[0002] A chestnut shelling machine is an advanced agricultural machine, mainly used for shelling during the chestnut processing process, aiming to improve the shelling efficiency and reduce labor costs. Specifically, the working principle is that the motor drives the sheller to rotate, and the sheller further rotates under the action of the conveyor belt to send chestnuts into the machine. Inside the sheller, through continuous stirring of the clamping pieces, the spiny shells of the chestnuts are removed and broken at the threaded steel bar grid, thereby achieving the purpose of shelling.

[0003] Currently, during the use of the chestnut shelling machine, the operator shovels the chestnuts with shells to the feeding port. After entering the roller and completing the shelling under the rotation of the sheller, they are then conveyed to the screening device for screening the shells and chestnuts. However, in the feeding step, since the feeding port is directly connected to the roller, due to the particularity of the chestnut shell, when entering the roller, it will splash due to the rotational force inside the roller. This requires the operator to put the splashed chestnuts back into the feeding port again, increasing the workload. Content of the Utility Model

The transmission device is provided with a motor 51 and a plurality of belts 52. A rotating shaft 33 is provided on the same side central axis of the first roller 31 and the second roller 32. The rotating shaft 33 is axially connected to the output end of the motor 51 through the belt 52. The screening device is located below the first roller 31 and the second roller 32. The motor 51 is fixed on the frame 1 and is located below the screening device.

[0027] Please continue to refer to Figure 1As shown in the figure, a first discharge port 311 is provided at the bottom of the first roller 31. An activity baffle (not shown in the figure) is provided at the first discharge port 311. A second discharge port is provided at the bottom of the second roller 32. An activity baffle is also provided in the connection channel between the first roller 31 and the second roller 32. During the use of the hulling machine of the present invention, the chestnuts with hulls enter the first roller 31 from the feed hopper 2 and are hulled by the huller in the first roller 31. In necessary cases, the raw materials can be hulled twice. Specifically, the activity baffle below the first roller 31 is opened, and the activity baffle between the first roller 31 and the second roller 32 is opened, so that the chestnuts can pass through the first roller 31 and the second roller 32 in sequence to achieve double hulling treatment. The hulled chestnuts are screened by the screening device.

[0028] In addition, as Figure 1 shown, the screening device is provided with a bent plate 43, a first sieve plate 41, a second sieve plate 42 and a bottom plate 44. The first sieve plate 41, the second sieve plate 42 and the bottom plate 44 are arranged in sequence from top to bottom. The first sieve plate 41 can screen out the hulled chestnuts and enter the second sieve plate 42. An outlet is provided at one end of the second sieve plate 42 away from the bent plate 43. The screened chestnuts enter the storage bag through this outlet for collection.

[0029] Please also refer to Figure 1 and Figure 2 shown. In this embodiment, a pressing plate 60 is provided at the inlet of the feed hopper 2 of the chestnut hulling machine. The pressing plate 60 includes a fixed frame 61 and a plurality of pressing plates 62. The pressing plates 62 are hinged to the top corners of the fixed frame 61.

At the same time, another belt 52 sleeved on the rotating shaft 33 drives the rotating member 7, thereby starting the vibrator and driving the vibration of the screening device, and then realizing the processes of chestnut screening and impurity treatment. In addition, this embodiment further includes a dust removal device, and the dust removal device includes a blower and a dust removal chamber. The dust removal device is used to collect the substances on the bottom plate 44.

[0032] Through the above technical solutions, the beneficial effects of the present utility model include: a pressing plate 60 is provided at the feed hopper 2 of the present utility model. The pressing plate 60 can be compressed downward by means of the elastic force of the spring member 623 and automatically return to its original position when not subjected to external force. Thus, during the feeding process, when the chestnuts enter through the feed hopper 2, the pressing plate 62 of the pressing plate 60 can prevent the splashing chestnuts from leaving the feed hopper 2, and thus the step of manual secondary picking and then hulling can be omitted. In addition, the chestnut huller of the present utility model is provided with two hulling roller shafts, and the first roller shaft or both roller shafts can be selected for hulling treatment according to actual needs.
