Technical Field

[0001] The utility model relates to the technical field of agricultural product processing, in particular to a threshing device for agricultural products with branches which can prevent blockage by branches and leaves. Background Art

[0002] In agricultural product processing and production, after workers harvest the mature agricultural products together with the branches and leaves, they still need to go through processes such as drying, threshing, and screening to separate the fruits from the branches and leaves.

[0003] In order to solve the problem of labor-intensive and low-efficiency in the manual beating threshing process, a rotating beating plate can be used to beat and thresh the clamped agricultural products with branches at the end of the feed conveyor belt of the threshing device. The branches and fruit particles that have been beaten and threshed are separated through a screening and feeding mechanism to achieve efficient threshing.

[0004] However, some miscellaneous leaves, thin and short branches on the branches will be produced in large quantities after beating. The branches, miscellaneous leaves and thin and short branches after beating and threshing will easily cause branch blockage in the screening and feeding mechanism during the branch transportation process, which will seriously affect the transmission of the branches and thus reduce the threshing efficiency of the branches to be threshed. Utility Model Content

[0005] Based on the above problems, the utility model provides a threshing device for agricultural products with branches that can prevent clogging by branches and leaves. It can reduce the content of short branches and miscellaneous leaves in the screened fruits, improve the quality of the products, and also reduce the problem of clogging caused by accumulation of short branches and miscellaneous leaves in the screening and feeding mechanism.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0027] Example:

[0028] See also Figure 1 A device for threshing agricultural products with branches and preventing them from being blocked by branches and leaves comprises:

[0029] A frame 1, wherein the frame 1 is provided with a feed end and a discharge end;

[0030] A feed conveyor belt 2 is installed on the frame 1 and is used to convey the agricultural products with branches input from the feed end;

[0031] A clamping conveyor belt 3 is installed just above the end of the feed conveyor belt 2 in the transmission direction. The clamping conveyor belt 3 is used to form a gap with the feed conveyor belt 2 for the passage of agricultural products with branches, and the gap decreases along the direction of material movement. It is used to convey and clamp agricultural products with branches near the end of the feed conveyor belt 2 in the transmission direction;

[0032] The beating component 4 is installed on the frame 1 near the end position of the feeding conveyor belt 2 in the transmission direction, and is used to beat and thresh the agricultural products with branches output from the gap position;

[0033] The screening and conveying mechanism is located below the feed conveyor belt 2 and is used to receive the material output from the end of the feed conveyor belt 2. The screening and conveying mechanism includes a plurality of first rotating rods 5 arranged at intervals, and each first rotating rod 5 is fixed with a plurality of rotating pieces 6 at intervals to separate the particles that fall from the branches and convey the branches to the discharge end.

[0034] An air outlet 7 is provided on the frame 1 and is located above the end of the feed conveyor belt 2 in the transmission direction;

[0035] The air supply mechanism 8 is installed on the frame 1, the air outlet 7, the particle assembly 4 and the air outlet end of the air supply mechanism 8 are located on the same straight line, and the particle assembly 4 is located between the air outlet 7 and the air outlet end of the air supply mechanism 8.

[0036] In this embodiment, the feed conveyor belt 2 and the clamping conveyor belt 3 are both driven to rotate by a motor. The feed conveyor belt 2 conveys the agricultural products with branches to the gap between the feed conveyor belt 2 and the clamping conveyor belt 3. Since the gap decreases along the direction of material movement, the running directions of the feed conveyor belt 2 and the clamping conveyor belt 3 are set, so that the agricultural products with branches are clamped by the feed conveyor belt 2 and the clamping conveyor belt 3 and output from the end of the feed conveyor belt 2. The agricultural products with branches are beaten (beaten) by the beating component 4, so that the fruits of the agricultural products with branches are threshed from the branches. After beating and threshing, the branches and fruits fall into the screening and conveying mechanism, and the separation of the fruits and branches is realized by the screening and conveying mechanism. The separated branches are output from the discharge end during the rotation of the rotating piece 6. In this embodiment, before the branches after beating fall onto the screening and conveying mechanism, air can be blown to the branches by the air supply fan, so that the light leaves, thin and short branches and other impurities beaten in the branches are blown out of the frame 1 from the air outlet 7, and the fruits and whole branches on the branches fall onto the screening and conveying mechanism for separation due to their large weight, which can reduce the content of thin and short branches and miscellaneous leaves in the screened fruits and improve the quality of the product. It can also avoid the increase in the operating load of the screening and conveying mechanism after a large number of thin and short branches and miscellaneous leaves enter the screening and conveying mechanism, and reduce the problem of blockage caused by the accumulation of thin and short branches and miscellaneous leaves in the screening and conveying mechanism, so that the branches after beating can be transported stably and efficiently, ensuring the threshing quality and efficiency of the branches to be threshed on the feed conveyor belt 2.

[0037] In this embodiment, a windshield 9 is also installed on the frame 1. The windshield 9 is located between the air outlet 7 and the outlet end of the screening and feeding mechanism, and can play the role of wind shielding and diverting, ensuring that thin and short branches and miscellaneous leaves can be blown out of the air outlet 7. The windshield 9 in this embodiment is a flexible or elastic plate, which can ensure that the whole branches pass through the windshield 9 smoothly without causing blockage problems. It should be noted that the bottom of the windshield 9 can be tilted along the downstream of the screening and feeding mechanism, and the bottom of the windshield 9 can be extended to a position close to the top of the screening and discharging mechanism, further avoiding the problem that the windshield 9 is prone to blockage. In addition, the top of the windshield 9 is fixed at a position close to the edge of the air outlet 7, especially the top fixed end of the windshield 9 is set at the most downstream position of the air outlet 7. While ensuring wind protection, it can further ensure that thin and short branches and miscellaneous leaves can be blown out of the air outlet 7, rather than accumulating between the air outlet 7 and the windshield 9.

[0038] In this embodiment, a second rotating rod 10 is mounted on the frame 1, located upstream of the clamping conveyor belt 3. Comb-like teeth 11 are mounted on the second rotating rod 10 for combing the branched agricultural products on the feed conveyor belt 2. The rotating comb-like teeth 11 comb the incoming branches and guide them to the entrance of the gap, preventing the branches and any debris attached thereto from exceeding the entrance of the gap and causing blockage of the branched agricultural products.

[0039] The threshing device for branched agricultural products in this embodiment also includes a branch cutting mechanism 12. This mechanism 12 comprises a third rotating rod mounted above the rotating plate 6 and equipped with a plurality of comb-shaped rotating teeth. Each comb-shaped tooth is equipped with a blade for cutting off debris from the branches on the screening and feeding mechanism. The second rotating rod 10 drives the comb-shaped teeth 11 to initially comb the branches of the branched agricultural products on the feed conveyor 2. The third rotating rod and its blades then further cut debris from the branches after threshing. This dual combing and branch cutting mechanism not only improves production efficiency but also reduces production interruptions caused by blockages caused by debris, thereby ensuring stable operation of the entire branched agricultural products threshing line. In this embodiment, the central axis of the third rotating rod is perpendicular to the conveyor belt 2, ensuring that debris is cut, rather than cutting the branched agricultural products horizontally.

[0040] In this embodiment, the grain-beating component 4 includes a rotating drum and a grain-beating plate arranged on the rotating drum. The rotating drum drives the grain-beating plate to rotate, thereby beating and threshing the agricultural products with branches at the output end of the feed conveyor belt.

[0041] The frame 1 in this embodiment is provided with rollers 13 for the frame 1 to move. The rollers 13 are driven to rotate by a motor, so that the threshing device for agricultural products with branches and leaves that can be prevented from being blocked can be moved. After the agricultural products with branches are harvested, they are directly placed in the field for natural drying. Then, the movable threshing device for agricultural products with branches and leaves that can be prevented from being blocked by branches and leaves in this embodiment is used to perform the grain threshing operation. The operation is convenient and efficient, saving manpower and material resources.

[0042] In this embodiment, the branch-resistant agricultural product threshing device also includes a feed hopper 14 installed on the frame 1. The feed hopper 14 is fixed to a position corresponding to the feed end of the feed conveyor belt 2 on the frame 1, so as to facilitate movable field grain harvesting.
