Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of returning straw to fields, in particular to a deep crushing device for returning straw to fields. Background Art
[0002] Returning straw to the fields can increase soil organic matter, improve soil structure, make the soil loose, increase porosity, reduce capacity, promote microbial activity and the development of crop roots. When returning straw to the fields, in order to make the straw better turned into the soil and prevent large amounts of straw from having adverse effects on subsequent planting, the straw needs to be crushed.
[0003] According to a wheat straw crushing and returning device disclosed on the patent website (authorization announcement number: CN 220733602 U), "the utility model belongs to the technical field of straw returning to the field, and in particular to a wheat straw crushing and returning device, comprising a support frame, a crushing barrel is provided at the top of the support frame, the crushing barrel is rotatably connected to a guide seat, an atomizing pipe is fixedly connected to the inside of the crushing barrel, a spraying pipe is fixedly connected to the inside of the crushing barrel, a shielding cover is provided below the crushing barrel, and a scraper turntable is rotatably connected to the inside of the shielding cover; when the wheat straw is crushed by the crushing barrel and the guide seat, the atomizing pipe sprays atomized water to remove dust generated during the crushing process, and humidifies the crushed wheat straw after the atomized water drops, and the spraying pipe sprays the wheat straw, so that the wheat straw is in suitable conditions when it is returned to the field and composted, and the scraper turntable cooperates with the shielding cover to spread the wheat straw, so that the crushed wheat straw is evenly spread on the ground, thereby ensuring uniformity when the wheat straw is returned to the field."
[0004] In view of the above description, the applicant believes that the following problems exist:
[0005] During use, the utility model crushes the straw through the provided crushing barrel and guide seat, humidifies the crushed wheat straw after the atomized water drops, sprays the wheat straw with medicine through the spray pipe, and then sprinkles the wheat straw through the scraper turntable in cooperation with the shielding cover, so that the crushed wheat straw is evenly spread on the ground, thereby ensuring the uniformity of returning the wheat straw to the field. However, in actual use, the crushed and humidified straw has a certain viscosity and will adhere to the outside of the crushing roller and the inner wall of the crushing barrel. First, the straw adhered to the outside of the crushing roller may affect the subsequent crushing of the straw, thereby causing insufficient straw crushing and even blockage. Secondly, the straw adhered to the inner wall of the crushing barrel becomes thicker and thicker, which will make the discharge port gradually smaller, thereby causing abnormal discharge blockage, which is not convenient for subsequent return to the field. Therefore, it is necessary to improve a straw return to the field deep crushing device to solve the above problems. Utility Model Content

[0031] Furthermore, the rotating column 411 is movably installed inside the rotating drum 413, the two crushing rollers 44 are rotatably installed inside the crushing drum 2, the cleaning brush 46 is arranged on the outside of the crushing roller 44, and the bolt 47 is threadedly installed inside the crushing drum 2, so that the cleaning brush 46 can be replaced.
[0032] Embodiment 2:
[0033] See also Figure 5 , and combined with Example 1, it is further obtained that the returning mechanism 5 includes a motor 3 51, which is fixedly installed inside the support frame 1, and a turntable 52 is fixedly installed at the output end of the motor 3 51. Two guide plates 2 53 are fixedly installed inside the crushing cylinder 2, and an arc-shaped baffle 54 is fixedly installed on the inner side of the support frame 1. Two adjustment plates 55 are rotatably installed inside the arc-shaped baffle 54. Springs 2 56 are fixedly installed inside the two adjustment plates 55. A disc 57 is fixedly installed on the end of the spring 2 56 away from the adjustment plate 55. A plug post 58 is fixedly installed inside the disc 57, and the disc 57 can drive the plug post 58 to move.
[0034] Furthermore, the plug post 58 is slidably installed inside the adjustment plate 55, and a socket is provided at the corresponding position of the support frame 1 and the plug post 58, and the plug post 58 is inserted into the socket, so that the position of the adjustment plate 55 is fixed, which is convenient for adjusting the range of spreading wheat straw.
[0035] Furthermore, the disc 57 is slidably installed inside the adjustment plate 55, and the turntable 52 is set just below the gap between the two guide plates 53. The chopped platycodon grandiflorum falls to the top of the turntable 52 through the two guide plates 53, so that the chopped platycodon grandiflorum can be spread on the ground.
[0036] In actual operation, when this device is used, after the straw is transported into the crushing cylinder 2, the straw enters between the two crushing rollers 44 under the action of the two guide plates 13, the motor 141 drives the gear 142 to rotate, the gear 243 engages with the gear 142 to drive the two crushing rollers 44 to rotate synchronously in the opposite direction to crush the straw, and the cleaning brush 46 is arranged inside the crushing cylinder 2 through the mounting block 45 and the bolt 47. The cleaning brush 46 cleans the rotating crushing roller 44 to prevent the straw from adhering to the outside of the crushing roller 44 and affecting the subsequent crushing of the straw, thereby causing the problem of insufficient straw crushing. At the same time, the motor 24 is started. 10 drives the rotating column 411 to rotate, so that the rotating column 411 moves inside the rotating drum 413, so that the rotating drum 413 moves inside the moving block 412, and a spring 1 418 is provided between the second protrusion 417 and the movable block 414. The spring 1 418 is initially in a stretched state, so that the spring 1 418 drives the movable block 414 away from the crushing drum 2, thereby making the knocking column 416 away from the crushing drum 2. When the rotating column 411 rotates inside the rotating drum 413, driving the rotating drum 413 close to the crushing drum 2, at this time, the moving block 412 slides inside the rectangular plate 48, so that the connecting column 415 slides inside the second protrusion 417, driving the knocking column 416 to move away from the crushing drum 2. The column 416 knocks the crushing cylinder 2, and the spring 1 418 is compressed. When the rotating column 411 continues to rotate, the rotating column 411 no longer pushes the rotating cylinder 413 to approach the crushing cylinder 2. At this time, the spring 1 418 rebounds and drives the knocking column 416 away from the crushing cylinder 2, so that the knocking column 416 can knock the outside of the crushing cylinder 2 back and forth, causing the platycodon powder adhered to the inner wall of the crushing cylinder 2 to fall, and also making the platycodon powder fall faster, avoiding clogging of the discharge port. Before using the device, pull up the plug column 58 to disengage from the socket inside the support frame 1. At this time, the disc 57 moves up to compress the spring 2 56. The spring 2 56 is initially in a stretched state, and the adjusting plate 5 is rotated. Inside the arc-shaped baffle 54, after rotating to a suitable angle, the plug 58 is released. At this time, the spring 2 56 rebounds and drives the disc 57 downward, so that the plug 58 is inserted into the other socket, and the position of the adjustment plate 55 is fixed, which facilitates the adjustment of the wheat straw spreading range and makes it more convenient to adjust according to usage needs. The platycodon grandiflorum powder falls to the top of the turntable 52 through the two guide plates 2 53. The motor 3 51 drives the turntable 52 to rotate, so that the turntable 52 throws the platycodon grandiflorum powder to the ground so that it can be spread on the ground, preventing the accumulation of wheat straw powder, improving the uniformity of wheat straw return to the field, and achieving a better return effect.
