Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a soil crushing device for seedling raising. Background Art

[0002] In the process of agricultural planting, seedling raising needs to be carried out first. The existing seedling raising method is mainly carried out in seedling trays. After sowing is completed, a layer of fine soil needs to be covered in the seedling trays. The existing fine soil is mainly obtained by crushing the soil, so a soil crusher is needed.

[0003] As disclosed in the patent application number CN201620996962.1, an agricultural planting soil crushing device is provided. The anti-slip pad of this patent makes the crushing device placed more stably and plays a certain shock-absorbing role to reduce noise; the second feeding port is used to add some fertilizers necessary for planting crops while crushing the soil, so that the fertilizer and the soil are combined more fully; the extrusion roller can initially crush large soil blocks, facilitate the subsequent crushing work, reduce the wear of the crushing blades, and extend the service life; the crushing rod can crush the initially crushed soil again to make it more fully integrated with the fertilizer and more suitable for planting.

[0004] In the process of using the existing soil crushing device, the soil is first broken by the sawteeth on the extrusion roller. However, the sawteeth on the extrusion roller have a poor crushing effect on large-sized soil blocks, and there will be a slipping situation, which requires long-time crushing. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a soil crushing device for seedling raising to solve the problems of low soil crushing efficiency, long time consumption, and large limitation of the existing soil crushing equipment described in the background art.

[0007] A soil crushing barrel, which is arranged on two support plates;

[0008] A plurality of soil crushing rollers, which are rotatably arranged in the soil crushing barrel;

[0009] A soil crushing cover, the lower end of which is open and arranged on the upper port of the soil crushing barrel, and the upper end wall of the soil crushing cover is provided with a feeding port;

[0010] A pressing plate, which is annular and is arranged in the soil crushing cover in a liftable manner;

[0011] A guiding plate, which is conical and is located in the soil crushing cover, and the guiding plate is fixedly connected to the soil crushing barrel through a support rod;

[0012] Wherein, the guiding plate is used to introduce the soil blocks onto the inner wall of the bottom of the soil crushing cover;

[0013] The airbag cloth is arranged on the inner circumferential wall of the soil crushing cover. The airbag cloth and the inner wall of the soil crushing cover form an airbag. At the position corresponding to the airbag on the side wall of the soil crushing cover, there are a number of air pipes, and electromagnetic valves are provided on the air pipes.

[0014] Preferably, a number of pressure rods are arranged on the lower surface of the pressing plate.

[0015] Preferably, at the position corresponding to the pressing plate on the upper end wall of the soil crushing cover, there is a hydraulic cylinder, and the output end of the hydraulic cylinder is fixedly connected to the pressing plate.

[0016] Preferably, at the position corresponding to the feed inlet on the soil crushing cover, there is a feed pipe.

[0017] Preferably, a material guiding hopper is fixedly connected to the inner wall of the soil crushing barrel, and the material guiding hopper is located above the soil crushing roller.

[0018] Preferably, at the position corresponding to the rotating shaft of the soil crushing roller on the outer wall of the soil crushing barrel, there is a gearbox. The output end of the gearbox is connected to the rotating shaft of the soil crushing roller, and a driving motor for driving the gearbox is provided on the outer wall of the gearbox.

[0019] The beneficial effects of adopting the above technical solutions are as follows:

[0020] In this application, the pressing plate provided can first crush the incoming soil blocks for the first time, and then the airbag can expand the airbag cloth, so that the airbag cloth can push the crushed soil, making the crushed soil fall into the soil crushing barrel and be further crushed by the soil crushing roller. Therefore, the soil crushing method in this application has a good effect. Description of the Drawings

Detailed Description of the Embodiment

[0025] The following will describe the embodiments of the present utility model in detail with reference to the drawings.

[0026] As Figures 1-3, in the first embodiment, a soil crushing device for seedling cultivation includes

[0027] a soil crushing barrel 20, which is arranged on two support plates 10;

[0028] a plurality of soil crushing rollers 70, which are rotatably arranged in the soil crushing barrel 20;

[0029] a soil crushing cover 30, the lower end of which is open and arranged on the upper port of the soil crushing barrel 20, and a feed port 31 is provided on the upper end wall of the soil crushing cover 30;

[0030] a pressing plate 40, which is annular and is arranged in the soil crushing cover 30 in a liftable manner;

[0031] a material guiding plate 50, which is conical and is located in the soil crushing cover 30, and the material guiding plate 50 is fixedly connected to the soil crushing barrel 20 through a support rod 51;

[0032] wherein, the material guiding plate 50 is used to introduce soil blocks onto the inner wall of the bottom of the soil crushing cover 30;

[0033] a bladder cloth 60, which is arranged on the inner circumferential wall of the soil crushing cover 30, and the bladder cloth 60 and the inner wall of the soil crushing cover 30 form an air bag. A plurality of air pipes 61 are provided on the side wall of the soil crushing cover 30 corresponding to the air bag, and electromagnetic valves 62 are provided on the air pipes 61.

[0034] This embodiment is implemented as follows:

[0035] When this application is in use, soil blocks are put into the feed port 31. Under the guidance of the material guiding plate 50, the soil blocks fall on the lower inner wall of the soil crushing cover 30. Then the pressing plate 40 moves downward so that the pressing plate 40 can crush the soil blocks. Then, water is flushed into the air bag through the air pipe 61, so that the bladder cloth 60 pushes the soil blocks away, and the soil blocks fall into the soil crushing barrel 20. Then, the soil blocks are crushed by the rotation of the soil crushing rollers 70.

[0036] The advantage of this application compared with the prior art is that it can improve the crushing efficiency and effect of soil blocks.

[0037] Please refer to Figure 2 , a plurality of pressing rods 41 are arranged on the lower surface of the pressing plate 40.

[0038] The crushing effect on soil blocks can be improved by the pressing rods 41 on the pressing plate 40.

[0040] The pressing plate 40 can be driven to move vertically by the hydraulic cylinder 42.

[0041] Please refer to Figure 1 and 2 , at the position of the soil-breaking cover 30 corresponding to the feed inlet 31, there is a feed pipe 32.

[0042] Through the feed pipe 32, it is convenient for workers to put the soil clods in.

[0043] Please refer to Figure 2 , a material guiding hopper 73 is fixedly connected to the inner wall of the soil-breaking barrel 30, and the material guiding hopper 73 is located above the soil-breaking roller 70.

[0044] Through the material guiding hopper 73, it can be avoided that the soil moves to the gap between the soil-breaking roller 70 and the inner wall of the soil-breaking barrel 30.

[0045] Please refer to Figure 1 , at the position of the outer wall of the soil-breaking barrel 30 corresponding to the rotating shaft of the soil-breaking roller 70, there is a gear box 71. The output end of the gear box 71 is connected to the rotating shaft of the soil-breaking roller 70, and a driving motor 72 for driving the gear box 71 is provided on the outer wall of the gear box 71.
