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. 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.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, 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.

[0025] Example:

[0026] See also Figure 1 and Figure 2 , a threshing device for agricultural products with branches, comprising:

[0027] A feeding conveyor belt 1 is installed on the frame and is used to convey the agricultural products with branches;

[0028] A clamping conveyor belt 2 is installed just above the end of the feed conveyor belt 1 in the transmission direction. The clamping conveyor belt 2 is used to form a gap with the feed conveyor belt 1 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 1 in the transmission direction;

[0029] The beating component 3 is installed on the frame near the end position of the feeding conveyor belt 1 in the transmission direction, and is used to beat and thresh the agricultural products with branches output from the gap position;

[0030] A rotating rake includes a first rotating rod 4, the first rotating rod 4 being perpendicular to the conveying direction of the feed conveyor belt 1, and a first rake nail row 5 being provided on the first rotating rod 4. The first rake nail row 5 is used to comb the branched agricultural products on the feed conveyor belt 1 by rotating; each rake nail in the first rake nail row 5 is provided with a blade 6 on a side that contacts the branches;

[0031] A fixed rake comprises a positioning portion 7 and a second rake nail row 8, wherein the positioning portion 7 is fixed to the frame, and the second rake nail row 8 is mounted on the positioning portion 7, the second rake nail row 8 extends to a position close to the top of the feed conveyor belt 1 and interlaced with the first rake nail row 5, and each rake nail in the second rake nail row 8 is provided with a shearing edge that cooperates with the blade portion 6 of the first rake nail row 5.

[0032] In this embodiment, agricultural products with branches, such as pepper with branches, chili with branches, and rice with branches, are transported to the feed conveyor 1 by a loading mechanism or manual loading. The feed conveyor 1 transports the agricultural products with branches to the gap between the feed conveyor 1 and the clamping conveyor 2. The feed conveyor 1 and the clamping conveyor 2 are both driven to rotate by a motor. Since the gap decreases along the direction of material movement, the running directions of the feed conveyor 1 and the clamping conveyor 2 are set, so that the agricultural products with branches are clamped by the feed conveyor 1 and the clamping conveyor 2 and output from the end of the feed conveyor 1. At this time, the grain-beating component 3 beats (beats) the agricultural products with branches output from the gap, so that the fruits of the agricultural products with branches are threshed from the branches. Because a rotating rake is provided above the feed conveyor belt 1 of this embodiment, on the one hand, the rake nails on the first rake nail row 5 can be used to comb the branched agricultural products before entering the gap to prevent the branches from clogging the feed conveyor belt 1. On the other hand, the rotating first rake nail row 5 can also rake the weeds mixed in the branched agricultural products to the first rake nail row 5. Then, when the rotating first rake nail row 5 passes through the second rake nail row 8 of the fixed rake, the blade 6 and the shearing blade that cooperate with each other will shear the weeds on the first rake nail row 5, thereby achieving the goal of clearing the weeds in the branched agricultural products and cutting the weeds at the same time, which can further avoid the problem of weeds entangled on the various rotating parts of the threshing device for agricultural products with branches, and ensure the normal and stable operation of the threshing device for agricultural products with branches.

[0033] In this embodiment, the cantilever end of each rake nail in the second rake nail row 8 is tilted along the conveying direction of the feed conveyor 1. In other words, the second rake nail row 8 is arranged upstream of the fixed rake, and each rake nail in the second rake nail row 8 is tilted in the downstream direction, which can avoid the problem of clogging caused by the interaction between branches and the second rake nail row 8.

[0034] This embodiment also includes a screening and feeding mechanism located below the feed conveyor belt 1 and configured to receive material output from the end of the feed conveyor belt 1. The screening and feeding mechanism comprises a plurality of spaced-apart second rotating rods 9, each of which is fixed with a plurality of rotating blades 10 at intervals, configured to separate the particles that have fallen from the branches after being beaten and transport the branches to the discharge end. After being beaten and threshed, the branches and fruit fall into the screening and feeding mechanism, which separates the fruit from the branches. The separated branches are then transported from the discharge end as the rotating blades 10 rotate.

[0035] In this embodiment, a distance sleeve is provided between adjacent rotating pieces 10 on the same second rotating rod 9. The distance between the rotating rods can be adaptively set according to the type of branched products, and different distance sleeve sizes can be set to determine the distance between the rotating pieces 10 on each second rotating rod 9, to ensure that the branches and fruits after threshing enter the screening and feeding mechanism and the fruits can fall from the gaps between adjacent rotating pieces 10, and the size of the branches is made larger than the distance between the rotating pieces 10 on the second rotating rod 9, so that the branches can be driven by the second rotating rod 9 to drive the rotating pieces 10 to output the branches individually to the discharge end.

[0036] The grain-beating assembly 3 in this embodiment includes a rotating drum and a grain-beating plate disposed on the rotating drum, which is used to beat and thresh the agricultural products with branches discharged from the gap. The rotating drum drives the grain-beating plate to beat (grain-beat) the agricultural products with branches, so that the fruits of the agricultural products with branches are threshed from the branches.

[0037] In this embodiment, a plurality of first rake nail rows 5 are provided on the first rotating rod 4 , and the plurality of first rake nail rows 5 are centrally symmetrically arranged along the central axis of the first rotating rod 4 , thereby ensuring efficient removal of weeds in agricultural products with branches.

[0038] In this embodiment, the first rotating rod 4 is driven to rotate by a servo motor, and the servo motor is connected to the first rotating rod 4 through a belt transmission. The advantage of the belt transmission is that it can not only realize transmission, but also when the first rotating rod 4 is stuck, the servo motor can operate normally by slipping, which is not likely to cause the servo motor to burn out.

[0039] In this embodiment, the threshing device for agricultural products with branches further includes a feed hopper 11 mounted on the frame. The feed hopper 11 is fixed to a position corresponding to the feed end of the feed conveyor belt 1 on the frame, so as to facilitate movable field threshing.

[0040] The above is an embodiment of the present invention. The above embodiments and the specific parameters therein are only for the purpose of explaining the verification process of the utility model, and are not intended to limit the scope of patent protection of the present utility model. The scope of patent protection of the present utility model shall still be based on its claims.
