Description

Technical Field

[0001] The utility model belongs to the technical field of grass crushers, and more specifically, particularly relates to an agricultural grass crusher. Background Art

[0002] In animal husbandry, the feed used can be crop straw, etc. This can not only improve the utilization rate of straw, etc., avoid the waste of resources and environmental pollution caused by the straw being unable to be used and can only be burned, but also reduce the cost of breeding. However, if the straw is directly used as livestock and poultry feed, it is not only troublesome to use, but also difficult to digest. Therefore, the development of a new type of grass crusher is an inevitable requirement for social development and production, and will also make important contributions to improving the working efficiency of the grass crusher, saving energy, and promoting industrial development.

[0003] The existing publication number CN215269573U discloses an agricultural forage crusher. Although a plurality of first crushing knives are arranged on the peripheral side of the first crushing knife and are horizontally distributed with equal intervals, and a plurality of second crushing knives are arranged on the peripheral side of the second rotating shaft and are horizontally distributed with equal intervals, the forage can be crushed more thoroughly, and the crushed forage is easy for livestock to digest and absorb.

[0004] Based on the above, the inventors found the following problems: However, the spacing between the crushing knives of the grinder is fixed and has no adjustment function, resulting in the size of the crushed grass being always the same, while different livestock need to eat grass of different sizes, resulting in the deterioration of the scope of application of the grinder. At the same time, the grinder does not have the effect of screening the crushed grass, and some incompletely crushed grass is still used to feed livestock.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an agricultural grass crusher is provided to achieve a more practical purpose. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an agricultural forage crusher to solve the current problem that the size of the crushed forage is always the same, while different livestock need to eat forage of different sizes, resulting in a decrease in the scope of application of the crusher.

[0029] Among them, multiple groups of active crushing knives 6 are arranged vertically and equidistantly, and each group of active crushing knives 6 is provided with multiple active crushing knives 6, and multiple active crushing knives 6 are arranged circumferentially and equidistantly. The servo motor 4 drives the rotating shaft 5 to rotate, thereby driving the multiple active crushing knives 6 to rotate.

[0030] Among them, there are multiple fixed crushing knives 71, and the multiple fixed crushing knives 71 and the multiple groups of active crushing knives 6 are arranged in a one-to-one correspondence, so that the spacing between the multiple fixed crushing knives 71 and the multiple groups of active crushing knives 6 is the same. When it is necessary to adjust the size of the cut grass, the knob handle 11 is turned to drive the first threaded rod 10 to rotate on the second support rod 12 to change the horizontal height of the lifting rod 7, thereby adjusting the spacing between the fixed crushing knives 71 and the active crushing knives 6.

[0036] In the present invention, the size of the grass to be crushed is first adjusted according to the size of the grass to be crushed. By turning the knob handle 11, the first threaded rod 10 is driven to rotate on the second support rod 12 to change the horizontal height of the lifting rod 7, and then the distance between the fixed crushing knife 71 and the active crushing knife 6 is adjusted. When the lifting rod 7 moves up and down, the limit rod 8 slides in the slide groove 9, so that when the first threaded rod 10 is rotated, the lifting rod 7 will not rotate together. By turning the knob 19, the second threaded rod 18 is driven to rotate, and then the moving block 20 is driven to move, thereby driving A plurality of baffles 23 move simultaneously, and the screening holes 16 are blocked by the baffles 23. The size of the sieve holes 16 screening the grass is adjusted according to the size of the blocking, and then the servo motor 4 is started to drive the rotating shaft 5 to rotate, and drive the plurality of active crushing knives 6 to rotate, and then the grass is put into the feeding trough 2 for crushing, and the cut grass is screened by the screening plate 15. The grass that meets the specifications falls into the collecting box 13 from the screening holes 16, and the grass that does not meet the specifications falls on the top of the screening plate 15. Finally, the grass on the top of the screening plate 15 is crushed for the second time.
