Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

As shown in Figure 1, this small green edamame sheller is mainly composed of a frame 1, a vibrating feeding device 2, a roller shelling device 3, a screening device 4, a grain collection box 5 and a guide plate 6, among which the most critical components are It is a vibrating feeding device, a roll shelling device and a screening device.

The vibrating feeding device 2 is composed of a support frame 21, a body 22, a rocking wheel 23, a feeding roller 24, a discharging control board 25, a triangular material guide 26 and a material guide plate 27, as shown in FIG. 2 . The support frame 21 and the body 22 are connected by welding, and the triangular material guide plate 26 and the material guide plate 27 are connected with the body 22 by welding. The rocking wheel 23 and the feeding roller 24 are connected with the body 22 through rolling bearings, and the triangular material guide 26 facilitates the green edamame to enter the roller shelling device evenly.

Considering that the artificially placed green edamame is relatively messy, it is difficult to evenly fall into the roller shelling device, which will greatly affect the shelling efficiency of the green edamame sheller. As a result, 10 feed rollers and a rocking wheel are arranged in the front section of the feed device. Turn the rocker, the feed roller rotates and cooperate with the triangular guide plate, the green edamame can enter the roller shelling device in an orderly manner.

The ends of the multiple feeding rollers 24 in the storage hopper are equipped with gears, and the multiple gears are surrounded by chains. The rocking wheel 23 is fixedly connected to a feeding roller 24 through the body 22. With the rotation of the rocking wheel 23, it can drive multiple rollers. The feeding rollers 24 rotate synchronously and in the same direction, and together they drive the edamame in the storage hopper to be transported to the outside of the storage hopper.

The entire vibrating feeding device is connected to the frame through four connecting rods, as shown in Figure 5; it should be noted that the frame 1 is provided with an eccentric roller driven by a motor, and the bottom of the support frame 21 has a roller contacting the eccentric roller , the rotation of the eccentric roller drives the whole vibrating feeding device to vibrate at high frequency.

The roller dehulling device 3 is the core component of this small green edamame shelling machine. The green edamame is squeezed by the reverse rotation of the two rollers, and the shelling is gradually realized. The roll dehulling device is composed of a driving roll shaft 31 , a driven roll shaft 32 , a driven roll 33 and a driving roll 34 , as shown in FIG. 3 . The driving roller 34 is of a spindle structure, that is, the middle diameter is the largest, and gradually becomes smaller toward both sides. On the contrary, the middle diameter of the driven roller 33 is the smallest and gradually becomes larger toward both sides, and the radians of the driven roller 33 and the driving roller 34 match.

The two rolls are positioned and installed on the roll shaft through the shaft shoulder, and the two roll shafts are connected to the frame through rolling bearings, as shown in Figure 6.

The angle between the center line of the two rolls and the horizontal plane is set to 43° to improve the peeling efficiency. The assembly gap between the two rollers is about 1.5mm-2mm, which can only allow the green edamame pods to pass through, so as to realize the separate collection of the seeds and the pods. Squeeze, the edamame in the pod is squeezed upward, and finally the pod is stretched to achieve separation.

In the traditional extrusion shelling method, the rotation trajectory of the two rollers is circular, and the number of green edamame seeds peeled out by each rotation of the rollers is limited. Therefore, the roll shelling device is optimized, and the two rolls are designed to be arc-shaped, so that the number of grains peeled out by the rolls at one time can be increased, and the efficiency of the sheller can also be improved. At the same time, the curved surfaces of the two rollers are designed into a thread shape, which increases the friction force and positive pressure of the rollers on the green edamame, and facilitates the seeds to be released from the pods.

The screening device 4 is composed of a front support frame 41 , a rear support frame 42 and a screening mesh 43 , as shown in FIG. 4 . The main function of the screening device is to separate the peeled green edamame seeds from the insufficiently peeled green edamame, the seeds fall into the collection box, and the insufficiently peeled green edamame is subjected to secondary peeling. The setting of the screening device can effectively improve the work efficiency and save time.

The two support frames are connected with the screen by welding. The screening device is connected to the frame by four screws.

A grain collecting box 5 is arranged below the small green edamame sheller, as shown in FIG. 1 . The grain collection box is designed as a drawer for easy collection and removal of green edamame grains. As shown in Figure 7, the grain collection box is connected to the green edamame sheller frame through the cooperation of the slideways on both sides, the slideway is connected with the frame by screws, and the slideway is connected with the grain collection box by screws.

The guide plate 6 of the bean shell is connected to the frame of the green edamame sheller through three screws, as shown in Figure 8; the small green edamame sheller has a total of five pulleys, and the five pulleys are connected to the corresponding shafts through key connections.

The present invention is shown in Fig. 1, this type of green edamame shelling machine adopts the extrusion shelling method, and its working principle is: first put the green edamame into the storage hopper, rotate the rocking wheel 23, the feeding roller 24 rotates and cooperates with the output The feeding control board 25, the green edamame can fall on the triangular guide plate 26 relatively evenly, the exciting motor drives the feeding device to vibrate, and the green edamame falls into the roller shelling device through the guide plate 6. The flat end of the green edamame is first clamped by the rollers, and the driven roller 33 and the active roller 34 rotate in the opposite direction. Because there is a certain gap between the edamame grains, after being squeezed by the rollers, the grains and the bean shell will move relative to each other, and gradually The husks are opened and the kernels are separated from the husks. Due to the small gap between the two rollers, the edamame kernels cannot pass through, but the husks can. The bean shells fall into the grain collection box 5 through the screening device 4 . The grains peeled by the roller shelling device and the green edamame with insufficient shelling will fall on the screening device 4, and the holes on the screening net can only allow the grains to pass through, so the grains fall into the grain collection box 11 through the screening net. The green edamame with insufficient shelling continued to slide down and were collected manually for secondary shelling.

The core device of the present invention is a double-roller shelling device, which realizes the shelling of green edamame by means of the squeezing action of two counter-rotating rolls. The green edamame pods are transported to the driven roller by the vibration of the vibrating feeding device, the flat end of the edamame pod is first clamped by the roller, the two rollers rotate in the opposite direction, and the pod moves forward through the roller. Due to the small gap between the two rollers (less than the diameter of the green edamame), the thick drum in the middle of the edamame pod is difficult to pass through. There is a certain gap between the seeds of the edamame pods. Under the extrusion action of the roller, the seeds and the pods move relative to each other, so that the seeds stretch the pods and gradually break away from the shells to achieve shelling.

The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited to this. The equivalent replacement or change of the inventive concept thereof shall be included within the protection scope of the present invention.
