Technical Field

[0001] The invention belongs to the technical field of threshing, and in particular relates to a threshing device for fresh tung oil tree fruits. Background Art

[0002] In order to solve the shortage of grain and oil, in addition to planting oil crops, woody plant oils such as camellia oil and walnut oil have also been developed. However, due to the long cycle and low yield, they have not achieved the desired results. At present, a high-yield woody plant oil, tung oil (oil grape) oil, has been discovered and developed. This woody oil tree species overcomes the defects of camellia and walnut, can be planted in the east, west, south and north, and the yield of a single tree is 20-150 kilograms.

[0003] The fruit of the Chinese tung tree is hung in clusters like grapes. In the existing technology, the Chinese tung tree is often picked with part of the fruit and stem connected together. In order to quickly dry and squeeze the Chinese tung tree fruit, the fruit must be quickly removed and dried. At present, the Chinese tung tree fruit particles are mainly removed from the fruit clusters by hand, which is inefficient and costly.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Summary of the invention

The mountain ash fruit cluster branch is clamped by two conveyor belts 411 and moved along the axial direction of the threshing roller 3. During the movement, the fork rod 31 on the threshing roller 3 can fork the mountain ash fruit off the cluster.

[0029] Preferably, the driving unit 42 includes a first transmission gear 421, a second transmission gear 422 and a second motor 423; the first transmission gear 421 and the second transmission gear 422 are respectively mounted on the rotating shafts of the first pulleys 412 of the two conveying units 41; the first transmission gear and the second transmission gear 422 are meshed with each other, and the output shaft of the second motor 423 is connected to the first transmission gear 421; the first transmission gear 421 and the second transmission gear 422 are both located at the top of the box cover 2, and a gear box 21 is formed at the top of the box cover 2; the second motor 423 is fixedly mounted on the top of the gear box 21.

[0033] Preferably, the fork rod 31 is tilted toward the feeding direction, and the height of several fork rods 31 is wavy along the feeding direction. When the fork rod 31 is tilted toward the feeding direction, the fork rods 31 are more likely to enter between the fork rods 31 when the tung fruit clusters are moving, and the fork rods 31 will push the fruits down during the rotation. When the height of the fork rod 31 is set in a wavy form and the length of the fork rod 31 is constantly changed along the moving direction of the tung fruit, the tung fruit clusters can be constantly moved during the movement, and the fork rods 31 are more likely to be inserted between the fruit stalks.

It should be noted that the hands need to be kept above the protective plate 222 during the movement, and the tung oil spike branches pass through the through groove 223; this can prevent the hands from being accidentally injured by the conveyor belt 411.

[0035] Preferably, a threshing chamber 12 and a branch-throwing chamber 13 are formed in the threshing box, and the threshing chamber and the branch-throwing chamber 13 are separated by a partition, and the partition is in the plane where the axes of the two first pulleys 412 coexist, so that the branches can be thrown into the branch-throwing chamber 13 after passing through the partition; the branch-throwing chamber 13 is below the output end of the conveying component 4; the threshing chamber 12 is in front of the branch-throwing chamber 13; a first guide plate 14 is obliquely provided in the threshing chamber 12, and the first guide plate 14 forms a plurality of filter strips 141; in addition, a first discharge port 16 connected to the threshing chamber 12 is formed on a side wall of the threshing box of the first guide plate 14 near the input end of the conveying component 4, and a second discharge port 17 connected to the branch-throwing chamber 13 is formed on the side of the bottom of the threshing box 1 near the output end of the conveying component 4, and a A third discharge port 18 is connected to the threshing chamber 12, and the third discharge port 18 is below the first guide plate 14; specifically, a supporting foot is provided at the bottom of the threshing box, and frames are placed at the first discharge port 16, the second discharge port 17 and the third discharge port 18; when threshing, the Castanopsis chinensis fruits will fall into the threshing chamber 12, and roll out from the first discharge port 16 under the action of the first guide plate 14, and some fruit stalks may also be torn off by the threshing roller 3, at this time, they can fall below the first guide plate 14 through the filter strip 141, and fall into the frame from the third discharge port 18, while the branches falling into the branch throwing chamber 13 fall into the frame from the second discharge port 17, and finally the fruit and the stalk are separated. In addition, handles are provided on the two side walls of the threshing box 1 to facilitate lifting the entire device away.

[0036] The working process of the present invention is as follows: first, put the Castanopsis glabra fruit ears into the feed port 22, and release your hands until the two conveyor belts 411 clamp the branches of the Castanopsis glabra fruit ears. At this time, under the action of the two conveyor belts 411, they move along the length direction of the threshing roller 3. Under the action of the threshing roller 3, the Castanopsis glabra fruits can be forked off from the fruit stalks and fall into the threshing chamber 12 and roll out from the first discharge port 16, while the remaining branches will fall into the branch throwing chamber 13 and be discharged from the second discharge port 17, finally realizing the separation of the fruit and the fruit stalk.
