The secondary grinding of the grains is quick and convenient, and the grinding efficiency is high.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution in the embodiment of the present application is to effectively solve the problem that when the existing grains are milled, after the initial milling, there is usually uneven milling, and the grains are of different sizes. The existing milling device is only provided with a screening device, but the subsequent secondary milling of the grains still needs to be manually collected and milled, which consumes manpower and has low milling efficiency. The overall idea is as follows: A grain milling device for primary processing of agricultural products includes a milling machine 1, and the milling machine 1 is provided with a collection mechanism for facilitating secondary milling of the grains, and the collection mechanism includes a screen 2, a fixing frame 3 and a conveyor belt assembly Part 4, L-shaped support rods 11 are fixedly installed on both side ends of the mill 1, the screen 2 is located between the two L-shaped support rods 11, the fixed frame 3 is located on one side of the mill 1, the conveyor belt assembly 4 is fixedly installed on the side end of the fixed frame 3, a feed hopper 13 is fixedly installed on the upper end of the mill 1, and a discharge port 12 is fixedly installed on the lower end of the mill 1. When the user grinds the grains, the user can start the mill 1 and put the grains into the mill 1 from the feed hopper 13. The mill 1 will grind the grains put into the mill 1, and after grinding, the grains will be discharged from the discharge port 12;

[0024] A fixing plate 21 is fixedly installed between the two end portions of the screen 2 and the two L-shaped support rods 11. However, after the initial grinding, the grains are not completely ground, and there are coarser grains and finer grains. The finer grains will pass through the screen 2 and enter the collection box 22;

[0025] A blocking plate 31 is fixedly installed on the side end of the fixing frame 3, a guide plate 32 is fixedly installed on the upper end of the blocking plate 31, at least two pusher plates 41 are fixedly installed on the circumferential end of the conveyor belt assembly 4, the end of the pusher plate 41 is in contact with the blocking plate 31, and an inclined slot 42 is provided on the upper end of each pusher plate 41, and coarser grains will pass through the inclined screen 2 to the pusher plate 41 on the conveyor belt assembly 4. The user can start the conveyor belt assembly 4, and the start of the conveyor belt assembly 4 will drive each pusher plate 41 to move, and the pusher plate 41 will collect the coarser grains filtered from the screen 2, and the conveyor belt assembly 4 rotates to drive the inclined slot 42 to move upward;

[0026] The guide plate 32 is inclined, and a collecting box 22 is provided under the screen 2. The end of the inclined groove 42 is attached to the end of the blocking plate 31, so the grains in the push plate 41 will not fall. When the conveyor belt assembly 4 drives the push plate 41 to move to the upper end of the guide plate 32, the end of the push plate 41 is no longer in contact with the blocking plate 31, and the coarser grains in the push plate 41 will fall into the guide plate 32. The guide plate 32 is inclined, and the grains falling into the guide plate 32 will fall into the feed hopper 13, and then enter the grinding machine 1 for secondary processing.

[0027] In view of the problems existing in the prior art, the utility model provides a grain grinding device for the primary processing of agricultural products. The device is equipped with a conveyor belt assembly 4 and a push plate 41. After the initial grinding, the conveyor belt assembly 4 can drive the push plate 41 to move to collect the coarser grains, and then put them back into the feed hopper 13 for secondary grinding. No manual processing is required, and the secondary grinding of the grains is quick and convenient, with high grinding efficiency.

[0028] Working principle:

[0029] When the user is grinding the grains, the user can start the mill 1 and put the grains into the mill 1 from the feed hopper 13. The mill 1 will grind the grains put into the mill 1. After grinding, the grains will be discharged from the discharge port 12. However, the grains after the initial grinding are not completely ground. There are coarser grains and finer grains. The finer grains will pass through the screen 2 and enter the collection box 22, while the coarser grains will pass through the inclined screen 2 to the push plate 41 on the conveyor belt assembly 4. The user can start the conveyor belt. When the conveyor belt assembly 4 is started, each push plate 41 is driven to move. The push plate 41 collects the coarser grains filtered from the screen 2. The conveyor belt assembly 4 rotates to drive the chute 42 to move upward. The end of the chute 42 is attached to the end of the blocking plate 31, so the grains in the push plate 41 will not fall. When the conveyor belt assembly 4 drives the push plate 41 to move to the upper end of the guide plate 32, the end of the push plate 41 is no longer attached to the blocking plate 31, and the coarser grains in the push plate 41 will fall into the guide plate 32. The guide plate 32 is inclined, and the grains falling into the guide plate 32 will fall into the feed hopper 13, and then enter the mill 1 for secondary processing, and the coarser grains are secondary milled to ensure that the grain particles after milling are uniform. When the existing grains are milled, after the initial milling, there is usually uneven milling, and the grain particles are of different coarseness. The existing milling device is only provided with a screening device, but the subsequent secondary milling of the grains still needs to be manually collected and milled, which consumes manpower and has low milling efficiency. A conveyor belt assembly 4 and a push plate 41 are provided to cooperate with each other. After the initial grinding, the conveyor belt assembly 4 can drive the push plate 41 to move to collect the coarser grains and re-feed them into the feed hopper 13 for secondary grinding without manual processing. The secondary grinding of the grains is quick and convenient, and the grinding efficiency is high. In addition, the device is provided with a screen 2 and a collection box 22 to cooperate with each other. After each grinding, the grains can be filtered through the screen 2 to ensure that the grain particles after filtering are of uniform coarseness and fineness, thereby ensuring the production quality during grain grinding.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
