DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make its advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0020] Embodiment 1: Please refer to Figures 1-4 , the present utility model provides a technical solution: A subsoiler with a hydraulic lifting function, comprising: a subsoiler 1 and a bracket 7. The top of the bracket 7 is fixed with an oil cylinder bracket 3. A lifting oil cylinder 5 is hinged on the surface of the oil cylinder bracket 3. A lifting frame 4 is fixed on the piston rod of the lifting oil cylinder 5. A chute 12 is opened at the bottom end of the lifting frame 4. A number of groups of limit holes 16 are opened on the side wall of the lifting frame 4. The top end of the subsoiler 1 is slidably connected in the chute 12. A limit rod installation groove 13 is opened on the surface of the subsoiler 1. One end of a limit rod 14 is movably inserted into the limit rod installation groove 13. The other end of the limit rod 14 is movably inserted into a certain group of limit holes 16. The limit rod installation groove 13 is a circular groove body. The limit holes 16 are circular hole structures. The limit rod 14 is a round rod structure. A limit spring 15 is fixed at the end of the limit rod 14 extending into the limit rod installation groove 13. The other end of the limit spring 15 is fixed on the inner wall of the limit rod installation groove 13. A guide rail 8 is opened on the surface of the bracket 7. A number of groups of sliders 9 are slidably connected in the guide rail 8. The sliders 9 are in a "convex" shaped block structure. A guide sleeve mounting plate 10 is fixed at the end of the slider 9 extending out of the guide rail 8. There are two sets of lifting oil cylinders 5. The inlets and outlets of the two sets of lifting oil cylinders 5 are respectively connected through an oil pipeline 6. An anti-slip pad 17 is fixed on the surface of the slider 9.
[0021] In actual use, according to requirements, different numbers of deep loosening shovels 1 are inserted from the bottom between the guide sleeve 2 and the guide sleeve mounting plate 10. The guide sleeve mounting plate 10 is moved, causing the slider 9 to slide in the guide rail 8, thus moving the deep loosening shovels 1 to the desired position, thereby adjusting the distance between each group of deep loosening shovels 1. Then, the top of the deep loosening shovel 1 is inserted into the slide groove 12. During insertion, the limiting rod 14 is fully pressed into the limiting rod mounting groove 13, compressing the limiting spring 15. When the deep loosening shovel 1 is inserted into the slide groove 12 and the limiting rod mounting groove 13 is aligned with the limiting hole 16, the limiting spring 15 pushes one end of the limiting rod 14 into the limiting hole 16, thus limiting the deep loosening shovel 1 in the slide groove 12. This achieves the connection between the deep loosening shovel 1 and the lifting frame 4, completing the adjustment of the number and spacing of the deep loosening shovels 1. After adjustment, as described in the document with application number CN201320522390.X, the cylinder frame 3 is welded onto the existing subsoiler and subsoil rotary tiller, and the lifting cylinder 5 is installed. The cylinder body of the lifting cylinder 5 is hinged to the cylinder frame 3, and the piston rod of the lifting cylinder 5 is connected to the lifting frame 4 above the bracket 7. Then, the hydraulic oil inlet and outlet of the two sets of lifting cylinders 5 are connected through the oil supply pipe 6, and the oil supply pipe 6 is connected to the hydraulic system of the motor vehicle. The oil supply of the lifting cylinder 5 is controlled by the control valve to control the extension and retraction of the lifting cylinder 5, so that the height position of the lifting frame 4 of the subsoil shovel 1 is changed, realizing the synchronous arbitrary depth adjustment of the subsoil shovel 1. This replaces the traditional method of adjusting the tractor suspension or depth limiting wheel. This device is convenient, quick and improves the work efficiency.
[0022] Example 2: Based on Example 1, in order to reduce the wear of the deep loosening shovel 1, a guide sleeve 2 is installed on the surface of the guide sleeve mounting plate 10 by screws, and a gasket 11 is fixed on the surface of the guide sleeve mounting plate 10. The deep loosening shovel 1 is movably inserted into the gasket 11.
[0023] A gasket 11 is fixed on the surface of the guide sleeve mounting plate 10. The deep loosening shovel 1 is movably inserted into the gasket 11, so that the deep loosening shovel 1 will not rub against the guide sleeve 2 and the guide sleeve mounting plate 10 when it moves up and down. The gasket 11 is made of soft and wear-resistant rubber material, so that more wear occurs on the gasket 11.
[0024] In actual use, according to requirements, different numbers of subsoil shovels 1 are inserted from the bottom between the guide sleeve 2 and the guide sleeve mounting plate 10. The guide sleeve mounting plate 10 is moved, causing the slider 9 to slide in the guide rail 8, thus moving the subsoil shovels 1 to the desired position, thereby adjusting the distance between each group of subsoil shovels 1. Then, the top of the subsoil shovel 1 is inserted into the slide groove 12. During insertion, the limiting rod 14 is fully pressed into the limiting rod mounting groove 13, compressing the limiting spring 15. When the subsoil shovel 1 is inserted into the slide groove 12 and the limiting rod mounting groove 13 is aligned with the limiting hole 16, the limiting spring 15 pushes one end of the limiting rod 14 into the limiting hole 16, thus limiting the subsoil shovel 1 in the slide groove 12, achieving the connection between the subsoil shovel 1 and the lifting frame 4. After completing the adjustment of the number and spacing of the subsoil shovels 1, welding can be performed on the existing subsoiler and subsoil rotary tiller as described in the document with application number CN201320522390.X. The hydraulic cylinder frame 3 is used to install the lifting cylinder 5. The cylinder body of the lifting cylinder 5 is hinged to the hydraulic cylinder frame 3. The piston rod of the lifting cylinder 5 is connected to the lifting frame 4 above the bracket 7. Then, the hydraulic oil inlet and outlet of the two sets of lifting cylinders 5 are connected through the oil supply pipe 6. The oil supply pipe 6 is connected to the hydraulic system of the motor vehicle. The oil supply of the lifting cylinder 5 is controlled by the control valve to control the extension and retraction of the lifting cylinder 5, so that the height position of the lifting frame 4 of the deep loosening shovel 1 can be changed. This allows the deep loosening shovel 1 to be adjusted to any depth synchronously, replacing the traditional method of adjusting the tractor suspension or depth limiting wheel. This device is convenient, quick and improves work efficiency. A shim 11 is fixed on the surface of the guide sleeve mounting plate 10. The deep loosening shovel 1 is movably inserted into the shim 11, so that the deep loosening shovel 1 will not rub against the guide sleeve 2 and the guide sleeve mounting plate 10 when it moves up and down. The shim 11 is made of soft and wear-resistant rubber material, so that more wear occurs on the shim 11.
