Bridge assembly for agricultural works

 

(57) Abstract:

Usage: in the agricultural industry, in particular in devices for control peresecheniyami of agromet. The inventive Assembly provides for the consolidation of the wheel one or more reference self-propelled trucks sensors signal to stop the wheels of the carts after the passage of the scheduled cut from the site of the previous stop. The sensor has a magnet attached to the end plate, equipped with a gravitational load. The plate is fixed with use of a magnetic coupling, located on the wheel truck. The magnet interacts with the magnetic reed switch attached to the end of the arrow. The axis of rotation of the latter is also coaxial with the axis of the truck wheels, and the axle may be fixed in a predetermined position. The unit relieves the operator from counting the number of rows of plants and associated errors during transitions agromet from one job to the next. 1 C. p. F.-ly, 5 Il.

The invention relates to the agricultural industry and can be used in agromostveni.

The purpose of the invention facilitate the work of the operator agromet by automating the execution stops AGR is ment goals is ensured by the fact that the sensor magnet is fixed to the end plate, equipped with a gravitational load and fixed by means of an electromagnetic clutch that is located on an axis coaxial with the axis of the wheel truck, with the possibility of rotation with the wheel or independently relative to the axis, and a mechanism for specifying the planned segments of the transition path is made in the form of an arrow, the axis of rotation which is coaxial with the axis of rotation of the wheels of the truck to lock this arrow in a given spatial position, the reed switch of the above-mentioned sensor is installed on the end of the arrow, and the plate that secures the sensor magnet, equipped with a damping plate.

In Fig.1 shows the proposed unit, the cross-section of Fig.2 is a view of the gauge wheels; Fig.3 wheel and the sensor in a vertical diametrical section; Fig.4 is a view along arrow a in Fig.2 shows the interaction of the magnet and the reed switch of Fig.5 is a view along arrow And modified when the run unit.

Bridge Assembly for agricultural work has on the wheel 1 one or more reference self-propelled trucks 2, the sensor signal to stop the wheels of the carts after the passage of the planned stretch of road from the previous stanoeva electromagnetic clutch 6, located on an axis coaxial with the axis of the wheel truck, with the possibility of rotation with the wheel or independently relative to the axis. The setting mechanism of the planned segments of the transition path is made in the form of the arrow 8, the axis of rotation which is coaxial with the axis 9 of rotation of the truck with the possibility of fixing this arrow in a given spatial position, the sealed contact reed switch 7 of the above-mentioned sensor is installed on the end of the arrow. Axis 9 can be fixed in a given position by means of a screw 10, which after installation of the arrow to the desired position is screwed into a corresponding threaded socket on the plateau 11. Plateau 11, as the body 6 of the electromagnetic clutch is held in a stationary position by the rod 12 attached to the braces 13 wheel bearings. The conductors 14 reed withdrawn through the longitudinal channels in the axis 9 and the rod 12. The housing 6 of the electromagnetic clutch has a coil 15 and a spring-loaded by a spring 16 hollow core 17 with the disks 18 and 19 at the ends. When the coil 15 is de-energized, the spring force of the plate 4 through the friction pad is securely clamped between the disk 19 and the disk 20, which covers the cavity of the drum 21 using the sealing gasket 22.in order to speed up the calming plate 4, the locking magnet 3 sensor, equipped with light damping plate 24. The bridge Assembly is also provided with a hub 25 of the wheel, the housing 26 of the wheel gear; angular gear 27, the drive shafts 28, the motor-reducer 29 of the drive wheels, the movable platform 30 for mounting interchangeable guns, moving on wheels 31 for guiding farm Agramonte, push the Cam-roller 32 that communicates with the contact system 33, which may be used instead of the reed switch.

Bridge Assembly for agricultural work is used as follows.

When the operator needs to move the bridge Assembly to perform repeated operations on adjacent subsequent section, such as hilling rows of potatoes, the operator presses the power supply and start in motion all wheel unit, causing the unit begins with a small speed of the front to move up until the magnet 3, the spatial moving with the wheel 1 from the original upper position, will be moved and will be equal to the reed switch 7 and switch signal is given to stop all wheels of the unit. The value of the path on which you want to move the unit depends on the number of shares of the total width of Catamenia 7 and arrows 8 turn and set at a desired angle relative to a reference point, which plateau 11 always correspond to the twelve o'clock clockwise on the time dial, where the magnet 3 starts its movement. In the original upper position the magnet puts the load 5, when the disk 4 lashing, what happens when the winding 15 serves voltage, while the presence of light from the damper plate 24 substantially shortens the time of vibration of the disk, reducing him to a practically acceptable.

Move the reed switch and the fixation of its provisions comply with the screw 10 fixedly mounted on the plateau 11, for which the first screw turn of the screw slot and then turn to the appropriate new nest.

If the wheel unit (see Fig.2) moves from left to right, the reed switch will close its contact and stop the wheel Assembly when the magnet 3 rotates about 25 min on the minute hand. To increase the mileage of the wheels 1 to the stop screw 10 should be placed in the appropriate slot, for example, 50 minutes and minute hands, and if the transfer should be more than the circumference of the wheel 1, then put more of the selector device, for example, operating on the principle of stepper seeker who stopped the wheel Assembly is at the first signal of the reed switch, and C the trucks, in accordance with the provision rows on the ground and the provisions of the sighting rods, which are installed on each self-propelled cart, and ensures that the sighting rods always would be built over the bed and in a straight line. When deviations any of trucks the operator by pressing the appropriate button, includes a reversible gear motor 29 and adjusts the position of the trolleys. After the correction of the position of any of the trucks, and also after stopping the unit to a new position, either automatically or from the operator's hand, the winding 15 is provided, the disk 4 raskrasavitsa and under the influence of the load 5, the magnet 3 is the original upper position for repetition of the cycle of the unit.

If the unit is a short single chassis on it enough to have one sensor signal to stop the wheels mounted on any one wheel; a long multi-span bridge unit with one sensor may have two spaced cabins, allowing you to adjust the alignment of the sighting rod with two ends of agromet two operators at the same time, when the terrain does not allow you to see the rods from one cab. The presence of sensors on the wheels of all trucks allows you to use the processing circuit signarama spans automatically and reliably exactly on target and bed very complex).

A sufficient degree of sealing disk space 20 with a gasket 22 allows to use instead of the reed switch dust-tight contact system 33 (see modification according to Fig.5).

The device relieves the operator's attention, which is freed from the tedious drainage number of rows, free from errors, reduces fatigue.

1. BRIDGE ASSEMBLY FOR AGRICULTURAL WORK, including agromet at least one sensor signal to stop the wheels of the truck, made in the form magnetosensitive pair, the output of which through logical unit associated with the switch actuators trucks, the magnet sensor is installed with the possibility of joint rotation with the wheel, wherein the sensor magnet is fixed to the end plate, equipped with a gravitational load and fixed by means of an electromagnetic clutch that is located on an axis coaxial with the axis of the wheel truck, with the possibility of its rotation with the wheel or independently about the axis, and setting mechanism of the planned segments of the transition path is made in the form of an arrow, the axis of rotation which is coaxial with the axis of rotation of the wheels of the truck to lock this arrow is specified in the Unit p. 1, wherein the plate, the locking magnet sensor, equipped with a damping plate.
