Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to an energy-saving and environment-friendly straw rapid crushing device for agriculture with splash prevention. Background Art

[0002] Straw is the general term for the stems, leaves (ears) of mature crops. It usually refers to the remaining parts of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after harvesting the seeds. In order to reuse it, a straw crushing device will be used.

[0003] In the Chinese patent with the publication number CN220755639U, an energy-saving and environment-friendly straw rapid crushing device for agriculture with splash prevention is mentioned. It relates to the technical field of agricultural machinery and includes an outer shell I. The upper side of the outer surface of the outer shell I is fixedly connected with a feeding device. The right side of the upper surface of the feeding device is fixedly connected with a movable baffle. The upper surface of the movable baffle is provided with a limiting hole. The front left side of the outer surface of the feeding device is fixedly connected with a clamping device. The front surface of the outer surface of the outer shell I is fixedly connected with an outer shell II. Compared with the existing ordinary energy-saving and environment-friendly straw rapid crushing device for agriculture, when crushing straw, the straw is put into the feeding device, then the movable baffle is pushed to the left, and then the clamping device is clamped in the limiting hole of the movable baffle. When crushing, the straw will not splash out of the feeding device, preventing the waste of raw materials and the difficulty of recycling the splashed straw, which pollutes the environment.

[0004] When using the above straw crushing device, the movable baffle needs to be repeatedly opened and closed to quickly crush the straw, so it is troublesome to use. In addition, when crushing, its cutting blades are in a fixed position and cannot be adjusted, so it cannot be used for different purposes. For example, when making feed for cattle and sheep, larger particle sizes may be required to ensure the palatability and digestibility of the feed; when returning straw to the field, finer crushing degrees may be required to promote the decomposition of straw and the improvement of soil. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an energy-saving and environment-friendly straw rapid crushing device for agriculture with splash prevention to solve the problems existing in the prior art.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to Figures 1-4 as shown, the present utility model provides a fast straw crushing device for agricultural use with splash-proof and energy-saving and environmental protection functions, including a housing 1. A partition board 5 is vertically and fixedly connected inside the housing 1. A crushing assembly 7 is arranged on one side of the partition board 5, and a splash-proof assembly 6 is arranged on the side of the crushing assembly 7 away from the partition board 5;

[0027] The splash-proof component 6 includes two sets of conveyor belts 65, upper and lower. Inside the lower conveyor belt 65, there are a driving roller 67, a first linkage roller 68, and a second linkage roller 69. Inside the upper conveyor belt 65, there is a driven roller 63. The periphery of the conveyor belt 65 is provided with evenly arranged cutting blocks 66. The conveyor belt 65 is used to stably convey the straw to prevent splashing, and the cutting blocks 66 are used to assist in truncating the straw.

[0028] The pulverizing component 7 includes a pulverizing hopper 71, a pulverizing box 72, and a support frame 75. The support frame 75 is used to adjust the size of the pulverized particles.

[0029] In a further embodiment, the pulverizing hopper 71 is fixedly connected above the pulverizing box 72. The partition plate 5 is provided with a through groove at the position of the pulverizing box 72, and a part of the support frame 75 is slidably connected inside the pulverizing box 72.

[0030] In this embodiment, the pulverizing hopper 71 is used to guide the preliminarily cut straw. The connection between the pulverizing hopper 71 and the pulverizing box 72 is circular. The through groove of the partition plate 5 fits with the inner side of the pulverizing box 72. Thus, when the gap between the pulverizing cutter disc 73 and the pulverizing hopper 71 becomes smaller, the smaller the opening of the through groove through which the straw can pass, and thus smaller straw particles can be pulverized.

[0031] In a further embodiment, a driving motor 74 is installed at the bottom of the support frame 75. The output end of the driving motor 74 is installed with a pulverizing cutter disc 73. The pulverizing cutter disc 73 is located above the support frame 75 and inside the pulverizing box 72. Hydraulic cylinders 76 are provided on both sides of the support frame 75. The hydraulic cylinders 76 are installed inside the housing 1, and the output ends of the hydraulic cylinders 76 are fixedly connected to the bottom of the support frame 75.

[0032] In this embodiment, the driving motor 74 and the pulverizing cutter disc 73 are the pulverizing main bodies for pulverizing straw in the prior art.

[0033] In a further embodiment, a driving motor 61 is installed on the periphery of the housing 1. The output end of the driving motor 61 is connected to the driving roller 67. Both ends of the driven roller 63, the driving roller 67, the first linkage roller 68, and the second linkage roller 69 are rotatably connected to the inner wall of the housing 1. The driving roller 67 and the first linkage roller 68 are coplanar.

[0034] In this embodiment, the two sets of conveyor belts 65 are symmetrical, but the whole is inclined at 30 degrees, so that the driving roller 67 and the first linkage roller 68 inside the lower conveyor belt 65 are flush with the bottom of the port of the feed inlet 2, while the second linkage roller 69 is lower. Thus, when the straw enters the inside of the feed inlet 2, it will be first conveyed by part of the conveyor belt 65, and when it is at the inclined part, it will be truncated by the cutting blocks 66 between the two conveyor belts 65.

[0035] In a further embodiment, a driving gear 62 is fixedly connected to one end of the driving roller 67, a linkage gear 64 is fixedly connected to one end of the driven roller 63, the driving gear 62 is meshed with the linkage gear 64, both the driving gear 62 and the linkage gear 64 are rotatably connected inside the housing 1, and the output end of the driving motor 61 penetrates and is fixed to the driving gear 62.

[0036] In this embodiment, when the driving motor 61 operates, it will cause the lower conveyor belt 65 to rotate clockwise. After being transmitted by the driving gear 62 and the linkage gear 64, the driven roller 63 inside the upper conveyor belt 65 will rotate counterclockwise, thereby causing the upper conveyor belt 65 to rotate counterclockwise, achieving the counter-rotating of the two conveyor belts 65, and then cutting off the straw.

[0037] In a further embodiment, a feed inlet 2 is provided at one end of the housing 1, a discharge outlet 3 is provided at the other end of the housing 1, a dust-proof curtain 4 is installed at the port of the feed inlet 2, and a dust-proof baffle one 8 and a dust-proof baffle two 9 are provided on the side of the partition 5 away from the crushing assembly 7. The dust-proof baffle one 8 is located above the dust-proof baffle two 9.

[0038] In this embodiment, the dust-proof baffle one 8 and the dust-proof baffle two 9 have opposite inclination directions, and the dust-proof baffle one 8 is located at the through groove of the partition 5, so as to buffer the rapidly discharged straw, causing the dust to be raised, while the straw particles are guided.

[0039] The working principle of the present utility model is as follows:

[0040] When the crushing hopper 71 and the driving motor 74 can be driven through an external controller, the operation of the crushing hopper 71 will cause its output end to drive the driving gear 62 and the lower driving roller 67 to rotate clockwise, and the driving gear 62 meshes with the linkage gear 64 to make the upper driving roller 67 rotate counterclockwise, so that the two conveyor belts 65 drive the cutting blocks 66 to rotate in opposite directions, thereby conveying the straw, and the cutting blocks 66 can preliminarily cut the straw during this process, and convey it into the interior of the crushing hopper 71 and guide it into the interior of the crushing box 72. Then, when driven by the driving motor 74, the high-speed rotation of the crushing cutter disc 73 causes the straw to be crushed, quickly discharged from the through groove of the partition 5, and impacts on the dust-proof baffle one 8, causing part of the dust to float in the housing 1, while the heavier straw will be discharged from the discharge outlet 3 along the guidance of the dust-proof baffle one 8 and the dust-proof baffle two 9, and further enabling the discharge outlet 3 to have a certain anti-sputtering function;

[0041] Before the above processing, the hydraulic cylinder 76 can be driven as needed, so that the support frame 75 can drive the crushing cutter disc 73 and the driving motor 74 to move up and down to adjust the position, so that the distance between the crushing cutter disc 73 and the crushing hopper 71 can be adjusted, and then the overlapping part of the blade and the inner wall of the crushing box 72 can be adjusted. And since the through groove opened in the partition 5 is of a fixed size, the smaller the overlapping part, the smaller the crushing particles.

[0042] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
