Description

Technical Field

[0001] The invention relates to the technical field of chestnut processing, and in particular to a chestnut debulking device. Background Art

[0002] Chestnut, also known as chestnut and Chinese chestnut, is a plant of the genus Castanea of ​​the beagraceae family. It is native to China and grows in areas with an altitude of 370-2800 meters. It is mostly found in mountainous areas and has been widely cultivated by humans. Chestnuts are rich in nutrients, with a higher vitamin C content than tomatoes and more than ten times that of apples. Chestnuts also contain a wide range of minerals, including potassium, zinc, iron, etc. The existing chestnut processing process is: chestnut fruits on the mountain are picked manually, and then the picked chestnuts are transported to the foot of the mountain. Finally, the chestnuts are put into the chestnut de-brooming machine for de-brooming, so as to obtain chestnut fruits.

[0003] At present, the chestnut processing process is relatively cumbersome. Due to the large size of the existing chestnut debulking machine, transporting it to mountainous areas is not only time-consuming and laborious, but also requires laying circuits for power supply, which is too costly and difficult to achieve mountain operations. As a result, the cumbersome process of chestnut picking, transportation and debulking occurs, which increases work intensity and labor costs. For this reason, we propose a chestnut debulking device. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the current chestnut processing process is relatively cumbersome. Due to the large size of the existing chestnut debulking machine, transporting it to mountainous areas is not only time-consuming and labor-intensive, but also requires laying circuits for power supply, which is too costly and difficult to achieve mountain operations. As a result, the cumbersome process of chestnut picking, transportation and debulking occurs, which increases the work intensity and labor costs. The present invention provides a chestnut debulking device.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] A chestnut debulking device comprises a crushing barrel, the bottom of which is fixedly connected to a supporting base, and a driving motor is buried in the center of the upper end of the supporting base, the output shaft of the driving motor is arranged to pass through the center of the crushing barrel upward, and a center conical grinding wheel is fixedly connected to the output shaft of the driving motor corresponding to a key section of the inner cavity of the crushing barrel, the inner wall of the crushing barrel is provided with a conical inner wall grinding wall, and the spacing between the conical inner wall grinding wall and the center conical grinding wheel gradually decreases from top to bottom, the upper end of the crushing barrel is fixedly connected to a barrel cover, and a feeding port is provided between the upper end of the barrel cover corresponding to the conical inner wall grinding wall and the center conical grinding wheel, the upper end of the feeding port is fixedly connected to a feeding barrel, and a pre-cutting mechanism is provided in the feeding barrel.

[0007] Furthermore, the pre-cutting mechanism includes a plurality of elastic pressing plates, the upper end of each elastic pressing plate is fixedly mounted on the upper end of the inner wall of the feeding barrel, and the lower end of the elastic pressing plate is close to the center of the feeding barrel, and a cutting blade is fixedly connected to the inner wall of the elastic pressing plate near the lower end, and the width of the cutting blade is four to six millimeters.

[0008] Furthermore, the outer wall of the central conical grinding wheel and the inner wall of the conical inner wall grinding wall are both provided with spiral ridges, and the spiral ridges on the outer wall of the central conical grinding wheel and the spiral ridges on the inner wall of the conical inner wall grinding wall have opposite rotation directions.

[0009] Furthermore, a discharge port is provided on one side of the bottom of the crushing barrel corresponding to the conical inner wall grinding wall and the bottom gap of the central conical grinding wheel, and a material guide trough is fixedly connected to the inner side of the discharge port at the bottom of the crushing barrel.

[0010] Furthermore, a plurality of sweeping silicone plates are fixedly connected to the outer wall of the central conical grinding wheel in a circular array near the bottom, and the outer sides of the sweeping silicone plates abut against the inner wall of the conical inner wall grinding wall.

[0011] Furthermore, the upper end of the feeding barrel is threadedly connected with a fixed thread ring, and the upper ends of the plurality of elastic pressing sheets are respectively welded and fixed to the bottom of the fixed thread ring.

[0012] Furthermore, a circle of convex rings is provided on the outer edge of the bottom of the barrel cover, and a matching step is provided on the outer wall of the upper end of the crushing barrel. The bottom convex ring of the barrel cover is sleeved and fixed on the matching step on the upper end of the crushing barrel, and connecting bolts are threadedly connected at equal intervals on the outer side of the bottom convex ring of the barrel cover, and the inner ends of the connecting bolts pass through the bottom convex ring of the barrel cover and then abut against the outer wall of the matching step on the upper end of the crushing barrel.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention provides a crushing barrel, and the central conical grinding wheel in the crushing barrel can rotate at a uniform speed driven by a driving motor. After the chestnuts are picked, they are inserted from the feeding barrel and pushed by a short stick, so that the chestnut buds are cut with scratches by the pre-cutting mechanism and then fall into the conical inner wall grinding wall and the central conical grinding wheel. The rotating central conical grinding wheel rotates and crushes the chestnut buds, and the spacing between the conical inner wall grinding wall and the bottom of the central conical grinding wheel is five millimeters larger than the size of the chestnuts, so that the chestnut bud fragments larger than the chestnuts will continue to be crushed in the conical inner wall grinding wall and the central conical grinding wheel until the chestnuts are separated from the chestnut buds and fall from the gap between the conical inner wall grinding wall and the bottom of the central conical grinding wheel, so that the chestnuts are separated on site. The device has a compact structure and is easy to carry. It can be carried and used on site in the chestnut forest. The chestnut buds are easier to be crushed through pre-cutting, so as to avoid damage to the chestnuts caused by excessive crushing, thereby improving the crushing efficiency and reducing the breakage rate.

[0015] 2. The present invention provides multiple elastic pressing sheets and cutting blades. When the chestnut shrub is inserted into the center of the multiple elastic pressing sheets, the multiple elastic pressing sheets can keep their lower ends close to the center under the action of their own elastic force and keep in contact with the outer wall of the chestnut shrub. The cutting blade cuts the surface of the chestnut shrub passing through and cuts knife marks on the chestnut shrub to facilitate subsequent crushing and crushing. The width of the cutting blade can be changed according to the variety of chestnuts being processed, so that the width of the cutting blade is close to the skin thickness of the chestnut shrub and does not exceed the skin thickness of the chestnut shrub, thereby ensuring the cutting effect while avoiding scratching the chestnuts and improving the yield rate.

[0016] 3. The present invention sets up multiple sweeping silicone plates, and the lower end of the bottom spiral ridge of the conical inner wall grinding wall is set on the upper side of the sweeping silicone plate. The multiple sweeping silicone plates can sweep the chestnuts and chestnut fluff separated at the bottom of the crushing barrel as the central conical grinding wheel rotates, until they fall at the discharge port, so as to facilitate the discharge of the chestnuts in the crushing barrel.
