The sensor device to control straight multi-span agricultural unit
(57) Abstract:Use: agricultural machinery, in particular sensors for control straight multi-span agricultural unit. The inventive sensor device includes magnets 2 enclosed in the spaces of the buildings of the supporting drum 3 tyre wheel Assembly. The magnets are secured to the plates 4 with gravity loads 5. While the magnets moving past the reed switches 15, periodically close their contacts with sending signals to the control circuit straightness of the movement of the bridge Assembly. These signals are processed in a known manner and the circuit outputs control commands to the wheels of the roller trucks. 5 Il. The invention relates to the agricultural industry, for the design of sensor that monitors preserving the linearity of the front movement multi-span bridge agricultural unit.A known design of sensors for motion control multi-span agricultural unit, for example, and. C. the USSR N 1782367, class A 01 B 49/00. The disadvantage of this sensor is that handled by the bridge unit agropedia must be equipped with a system epecial high precision, however, engineering equipment agropedia and care system frames during operation is expensive.The closest device adopted by the author for the prototype, is the design of the sensor. C. the USSR N 1142065, class A 01 C 25/09. The disadvantage of the sensor prototype is its bulkiness and difficulty of use: to put the sensor wheel to the initial position you need to approach each of migrant self-propelled trucks, with time that has to be done periodically (to put the wheel with the magnets in the desired position) as the roughness of the surface microrelief of agropedia contribute misalignment and distortion in the testimony of the traversed path trailed driven wheels of the sensor. High intensity sensor; it is bulky and complicated.The goal of improving performance and simplifying the design and improving reliability.The possibility of the realization of this goal is achieved by the fact that: magnet sensor misalignment angles enclosed in the space corps support drum tyre wheel multispan Agramonte, with magnets attached to the plates supplied by the gravitational loads and fixed for rotation relative to the clutch, fastening plate with the supporting drums wheels.In Fig. 1 shows an example of using the sensor for motion control multi-front sprinkler, presents the cross-section of the pivot of Fig. 2 example of using a sensor to control the movement of agromet, movable platform which is used for fastening removable agricultural tools, shows a cross-section of agromet; Fig. 3 supporting the drum wheel, in which is mounted the plate with two magnets; Fig. 4 the drum of one of the supporting-driving wheels multi-passage unit in which is mounted a plate containing a single magnet; Fig. 5 view of the wheel support pivot in the direction of arrow a in Fig. 1, the wheel shown in vertical section.The sensor device to control straight multi-span agricultural unit placed in the wheels 1. The magnets 2 sensor enclosed in the spaces of the buildings of the supporting drum 3 tires on the plate 4, provided with a gravity loads 5. Plate fixed for rotation about their axes, which are aligned to the axes of the wheels 1 multi-span bridge unit.One is esino two magnets, and the size of angles and1can be changed by moving the magnets in the respective adjacent slot in the plate 4 than the set permissible misalignment course trucks. All other plates 4 located in the drums of the wheels other self-propelled trucks, have one magnet (see Fig. 4). With housing support drum 3 plates 4 are fastened and raskreplyayutsya through the disk 6 with the use of electromagnetic clutches, fixed in the casing 7. Each of the discs 6 are made integral and its peripheral ring 8 is made of a nonmagnetic material, for example, from aluminum. Each of the electromagnetic couplings consists of a body 9 with the winding 10 and a movable armature disk 11 and 12 at its ends. The force of the spring 13 of the disk 12 constantly presses the plate 4 plate 14 made of friction material, for example, from Ferodo, to the Central thickening of the disk 6, which holds the plate 4 with the body of the drum 3 and causes the plate 4 to move as a unit with the wheel 1.The following notation: 15 the switches sealed contacts, triggered from the magnets 2; 16, 17 fasteners that hold in the stillness of the body 9 of the electromagnetic clutch; 18 wheel hub; 19 case wheel redona pipe sprinkler; 24 platform agromet for mounting interchangeable agricultural tools, moving on wheels 25 on rails multisupport farm; thrust bearing 26, and 27 in the brackets carrying the water distribution pipe.The device operates as follows. Pre-pass on the right two corners of the magnet 2 on the plate 4 sets of wheels that defines the limits of permissible misalignment misalignment course trucks. Then the bridge unit array aligned along a straight line and then all of a winding of the electromagnetic coupling serves voltage, resulting in plate 4 are released and under the influence of gravity loads 5 take the right initial position, shown in Fig. 3, 4. After de-energizing the electromagnetic clutch, the force of the springs 13 all plates 4 zaselyaetsya and begin to make one with the walls of the drum 3 rotates with them. While the magnets 2, moving past the reed switches 15 periodically close their contacts, sending these signals to the control circuit, which are processed in a known manner and the circuit outputs control commands to the wheels of the trucks. (The processing method is not explained it well known and contains, for example, in the description of the prototype and the repetition would mnoh driven wheels and the connecting hinge devices; the sensor does not increase the external dimensions of the bridge unit, equivalent work when the movement of the bridge Assembly both in one and in other party;
much better is the performance features: just press the button on the remote control to put the magnets in the desired position, and not be suitable for this, for example, each trolley 800-meter "Kulani"; (by installing magnets in the desired position will be done periodically and frequently, as, for example, from geodetic practice it is known that the testimony dimensional driven wheels, which clung to the previously used measuring bogies in parallel, from the accidents of microrelief soon began to disperse);
installation of the sensor on the impellers of the unit immediately detects the slip of the wheels; this is useful as it gives an opportunity for timely and automatically take the right action, because it is known that the rejection of the necessary measures have led even to breakage of the water distribution pipe sprinkler machines. The SENSOR DEVICE TO CONTROL STRAIGHT MULTI-span AGRICULTURAL UNIT including magnets sensor misalignment angles, vzaimodeystviya drums tires characterized in that the magnet sensor misalignment angles enclosed in the space corps support drum tyre wheel multispan Agramonte, with magnets attached to the plates supplied by the gravitational loads and fixed for rotation about their axes placed coaxially with the axes of the wheels of multispan Agramonte, when this sensor has a magnetic coupling, fastening plate with the supporting drums wheels.
