Bunker genolagani machine
(57) Abstract:The invention relates to the mechanization of agricultural production, namely, land reclamation machines, and can be used on granolithic machines for the construction of close horizontal drainage. Bunker genolagani machine includes a box-shaped compartment, granolithic and formulacell-sealer loose protective filter material. Formulacell-seal has a width that matches the width of the trench, and made with consobrina corrugated working surface with narrowing of the diameter of the cone from its front side in the moving direction genolagani machine to its rear side, the inner diameter of the cone of formulates-sealer in its rear part is larger than the diameter of the drainage pipe on the thickness of the layer of loose protective filter material. Formulacell-sealer loose protective filter material is attached pivotally to the back of the box-shaped compartment, while between them the pressure spring. Improving the quality of construction by improving the operating conditions of the drainage pipe. 1 C.p. f-crystals, 4 Il. The invention relates to the field of agricultural mechanization is jitelstva closed horizontal drainage.Famous bunker genolagani machine, consisting of a box-shaped compartment defined therein the guide rollers for the laid pipe. In the box-shaped compartment is filled loose protective filter material (sand, rubble, gravel), which then sprinkled drainage pipe laid at the bottom of the drainage trench (B. C. Klyuchnikov and L. A. Kamishina "Mechanization of reclamation works". Leningrad: "Kolos". Leningrad branch, 1978, page 53).A disadvantage of the known device is that this bunker provides not only filling the drainage pipe to a given layer of loose protective filter material, and filling the cross-section of the drainage trench. This leads to a large (up to 0.3 m31 meter drains) flow bulk protective filter material, while the bulk protective filter material is not compacted, which leads to swelling (lifting from the bottom of the trench) plastic drain pipes, or its deformation (compression) soil falling into the trench when Samoobrona walls of the drainage trench, or soil entering the trench when backfilling.The closest technical solution is the hopper granolithic, enabling the least, also mounted on the rear wall of the box-shaped compartment scheduler loose protective filter material. While the scheduler is executed in the form lodkoobraznuyu of formulates with the side walls in the form of plates arranged in parallel and connected to the hopper for movement along the length of the trench (A. C. the USSR 1472583, MKI E 02 F 5/10, 1989).The disadvantage of this device is the fact that the bunker with the scheduler does not provide a quality seal loose protective filter material over the drain pipe, because this layer of protective filter material does not affect the sealing force from the scheduler. In addition, the scheduler, located behind the bunker, not protects laid on the bottom of the trench drain pipe from deformation (compression), the ground breaking of the walls of the trench or soil entering the trench when backfilling.The objective of the invention is the stability of the provisions of the drainage pipe, preventing its deformation (compression) from collapsing soil trench and soil coming into the trench when backfilling, and compaction of granular protective filter material.The task of the invention is the achievement of Titel loose protective filter material, this formulacell-seal has a width that matches the width of the trench, and made with bonusnobanes corrugated working surface with narrowing of the diameter of the cone from its front side in the moving direction genolagani machine to its rear part, with the inner diameter of the cone of formulates-sealer in its rear part is larger than the diameter of the drainage pipe on the thickness of the layer of loose protective filter material. In addition, formulacell-sealer loose protective filter material is attached pivotally to the back of the box-shaped compartment, while between them the presser spring.In Fig.1 shows a hopper genolagani machine (side view) with the hinge attached and spring formulacell-seal loose protective filter material. In Fig. 2 shows formulacell-seal (side view), and Fig.3 is a cross section of formulates-sealer of Fig.4 shows a diagram of backfill drainage trench the ground, falling on formulacell - sealant, located under the drain pipe and thereby protect it from deformation (compression).Information confirming the possibility of carrying out the invention
Formatoutput width of the trench, at the bottom of which is placed a drainage tube. The inner cavity of formulates-seal 2 is made conical and tapers from the front to the back. Formulacell-seal 2 is attached to the box-shaped compartment with hinge 3. Consobrina corrugated surface of formulates-sealer with 2 sides provided with a turned back up the wing 5, the contour of which is geometrically from the front edge to the rear, and the radii of curvature R1and R2in this same sequence is reduced, which allows you to condense loose protective filter material throughout the cross section of the drainage trench.Between the rear wall of the box-shaped compartment 1 and formulateed-seal 2 fixed clamping spring 4, the force which is transmitted through formulacell-seal 2 to the sealing layer of loose protective filter material.In the process genolagani machine loose protective filter material is poured from the box-shaped compartment I and ossipee laid on the bottom of the trench drain pipe 6. Formulacell-sealer 2 compacts (compacts) bulk protective filter material due to the narrowing of the inner cone of formulates-seal 2. The compression ratio (seal) the tel-2. In addition to the seal loose protective filter material, formulating-sealer 2 protects the drainage pipe 6 from the deformation (compression), the ground breaking of the walls of the drainage trench. Breaking from the walls of the trench the soil and the soil is poured into the trench with the longitudinal conveyor genolagani machine falls (Fig.4) on formulacell-seal 2, located above the drain pipe 6, thereby protecting the pipe 6 from the deformation (compression). After advancing genolagani machine (and hence formulates-sealer 2), soil presses drainage pipe 6 and does not allow her to break away from the bottom of the trench. The length "L" of formulates-seal 2 is made equal to the depth HTrthe drainage trench, and an inner diameter of the cone of formulates-seal 2 in its rear part is larger than the diameter of the drainage pipe on the thickness of the bulk protective filter material, tsepelovo over the drainage pipe.Thus, the use of formulates-seal 2 with a conical inner surface allows you to condense the bulk layer protective filter material over the drain pipe 6, which prevents swelling of the drainage tube 6 and its damage (compression) ground, collapsing with stroitelnyh defects closed horizontal drainage and thereby improves the quality of its construction. 1.
