Description

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 that has a branch cutting function. 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, during the branch conveying process of the screening and conveying mechanism, the branch blockage problem is easy to occur in the screening and conveying mechanism, which seriously affects the transmission of the branches and thus reduces the threshing efficiency of the branches to be threshed. Utility Model Content

[0010] A beating assembly is installed on the frame near the end of the feed conveyor belt in the transmission direction, and is used to beat and thresh the agricultural products with branches output from the gap position;

[0011] A screening and conveying mechanism is located below the feed conveyor belt and is used to receive the material output from the end of the feed conveyor belt; the screening and conveying mechanism includes a plurality of first rotating rods arranged at intervals, each of which is fixed with a plurality of rotating plates at intervals, which are used to separate the particles that fall from the branches and convey the branches to the discharge end;

The second rotating rod is equipped with a plurality of comb-shaped rotating teeth, and each comb-shaped rotating tooth is equipped with a blade for cutting off the miscellaneous branches on the branches of the screening and feeding mechanism by rotating the blade.

[0013] Furthermore, a third rotating rod is installed on the frame, and the third rotating rod is located upstream of the clamping conveyor belt. The third rotating rod is installed with comb teeth for combing the agricultural products with branches on the feeding conveyor belt.

[0014] Furthermore, the central axis of the second rotating rod is perpendicular to the transmission direction of the screening and conveying mechanism.

[0015] Furthermore, the blade is detachably mounted on the corresponding rotating tooth via bolts.

[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 and Figure 2 , a threshing device for agricultural products with branches and a branch cutting function, comprising:

[0029] A feeding conveyor belt 1 is installed on the frame and is used to convey the agricultural products with branches;

[0030] 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;

[0031] 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;

[0032] A screening and feeding mechanism is located below the feed conveyor belt 1 and is used to receive the material output from the end of the feed conveyor belt 1. The screening and feeding mechanism includes a plurality of first rotating rods 4 arranged at intervals, and each first rotating rod 4 is fixed with a plurality of rotating pieces 5 at intervals to separate the particles that fall from the branches and transfer the branches to the discharge end.

[0033] The branch cutting mechanism includes a second rotating rod 6, which is installed above the rotating plate 5. The second rotating rod 6 is equipped with a plurality of comb-shaped rotating teeth, and each comb-shaped rotating tooth is equipped with a blade 7, which is used to cut off the miscellaneous branches on the branches of the screening and feeding mechanism by rotating the blade 7.

[0034] In this embodiment, the feed conveyor belt 1 and the clamping conveyor belt 2 are both driven to rotate by a motor. The feed conveyor belt 1 conveys the agricultural products with branches to the gap between the feed conveyor belt 1 and the clamping conveyor belt 2. Since the gap decreases along the material movement direction, the running directions of the feed conveyor belt 1 and the clamping conveyor belt 2 are set, so that the agricultural products with branches are clamped by the feed conveyor belt 1 and the clamping conveyor belt 2 and output from the end of the feed conveyor belt 1. The agricultural products with branches are beaten (beaten) by the beating component 3, 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 5. In the process of outputting the branches after beating, the branch cutting mechanism located above the screening and feeding mechanism can cut the miscellaneous branches of the branches, thereby avoiding the problem that the miscellaneous branches of the branches are easily lifted up and abut against the inner wall of the frame and then accumulate and clog in the screening and feeding mechanism, so that the branches after beating can be transported stably and efficiently, ensuring the threshing efficiency of the branches to be threshed on the feed conveyor belt 1.

[0035] In this embodiment, a third rotating rod 8 is mounted on the frame, located upstream of the clamping conveyor belt 2. Comb-like teeth 9 are installed on this third rotating rod 8 to comb the branched agricultural products on the feed conveyor belt 1. After the rotating comb-like teeth 9 comb the incoming branches, they are guided to the entrance of the gap, preventing the branches and their associated debris from exceeding the gap entrance and causing clogging of the branched agricultural products. Furthermore, during the coordinated operation of the clamping conveyor belt 2, the feed conveyor belt 1, and the screening and conveying mechanism, the third rotating rod 8 and the second rotating rod 6 work together to form a highly efficient combing, anti-clogging, and grain-beating system. The specific working process is as follows: the third rotating rod 8 drives the comb teeth 9 to first preliminarily comb the branches of agricultural products with branches on the feed conveyor belt 1 and introduce them into the gap between the clamping conveyor belt 2 and the feed conveyor belt 1. After beating the grains, the second rotating rod 6 further cuts the miscellaneous branches on the branches after beating the grains. This dual anti-blocking mechanism of combing + cutting branches not only improves production efficiency, but also reduces the problem of production interruption caused by blockage caused by branches and miscellaneous branches, thereby ensuring the stable operation of the entire agricultural products with branches threshing production line.

[0036] In this embodiment, the central axis of the second rotating rod 6 is perpendicular to the transmission direction of the screening and feeding mechanism, ensuring that the miscellaneous branches are cut instead of the agricultural products with branches being cut horizontally.

[0037] The blade 7 in this embodiment is detachably mounted on the corresponding rotating tooth by means of bolts, which enables detachable installation of the blade 7 and facilitates repair or replacement of a damaged blade 7 .

[0038] In this embodiment, a distance sleeve 10 is provided between adjacent rotating pieces 5 on the same first rotating rod 4. The spacing of the first rotating rods 4 can be adaptively set according to the type of branched products, and different sizes of the distance sleeves 10 can be set to determine the spacing of the rotating pieces 5 on each first rotating rod 4, 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 5, and the size of the branches is made larger than the spacing of the rotating pieces 5 on the first rotating rod 4, so that the branches can be driven by the rotating pieces 5 through the first rotating rod 4 to output the branches individually to the discharge end.

[0039] In this embodiment, the grain-beating component 3 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.

[0040] In this embodiment, a seed material conveyor belt 11 for transporting the granular material under the screen of the screening and conveying mechanism is provided below the screening and conveying mechanism, which can realize the efficient collection and transportation of the granular material produced by beating and threshing.

[0041] In this embodiment, a baffle plate 12 is provided on the frame, and the baffle plate 12 is located between the end of the feed conveyor belt 1 and the inlet end of the screening and feeding mechanism. The setting of the baffle plate 12 can ensure that the branches can accurately fall onto the screening and feeding mechanism after the grain beating is completed, avoiding the problem of the branches easily falling onto the seed material conveyor belt 11.

[0042] The frame in this embodiment is provided with rollers 13 for the frame to move. The rollers 13 are driven to rotate by a motor to realize the movable operation of the agricultural product threshing device with branch cutting function. After the agricultural product with branches is harvested, it is directly placed in the field for natural drying, and then the movable agricultural product threshing device with branch cutting function in this embodiment is used to perform the grain beating operation. The operation is convenient and efficient, saving manpower and material resources.

[0043] In this embodiment, the branched agricultural product threshing device with branch cutting function also includes a feed hopper 14 installed on the frame. The feed hopper 14 is fixed to a position corresponding to the feed end of the feed conveyor belt 1 on the frame, so as to realize movable field grain harvesting.

[0044] The above is an embodiment of the present invention. The above embodiment and the specific parameters therein are only for the purpose of clearly describing the verification process of the utility model and are not intended to limit the scope of patent protection of the present utility model.
