Background technique

According to the applicant's understanding, for a long time, the pod removal of soybean (edamame) has always relied on manual operation, which has low efficiency and high labor intensity. The search found that although there are patent applications for threshing of bean crops, for example, the Chinese patent application No. 90204717.5 discloses a "bean thresher", the threshing cylinder of this machine consists of a threaded rod with threaded teeth and a threaded rod without The spiked threaded rods are connected on two different circumferences of the threshing drum disc. In addition, the Chinese patent application with the application number 200620022454.X discloses a "soybean thresher", which includes a feed inlet, a threshing chamber, a discharge chamber, a slide plate and a discharge port, between the threshing chamber and the discharge chamber There is a screen in between, and there is an exhaust fan on the opening on the side of the discharge chamber. There is a rotating shaft in the threshing chamber, and there are rake teeth on the rotating shaft. Both the rotating shaft and the exhaust fan are driven by a motor through a belt. However, none of these prior art techniques is suitable for depodding soybeans.

Utility model content

The purpose of this utility model is: to propose a green soybean pod removal machine, thereby realizing the mechanized operation of soybean pod removal, improving efficiency and reducing labor intensity.

In order to achieve the above purpose, the green soybean pod removal machine of the present utility model includes a frame, the upper part of the frame is provided with a conveying chain sent in the horizontal direction, and the lower part is provided with a cleaning fan; the middle part of the conveying chain is equipped with a rotating Pod removing device; wherein, the conveying chain is located on one side of the frame, and the clamping platen above the conveying chain constitutes a clamping and conveying mechanism; the depodding device is supported by at least one pair of upper 1. The lower pod roller is formed, the roller shaft of the pod roller has flexible pod teeth distributed at intervals and radially extending, the axis of the roller shaft is at an angle to the conveying direction; the upper and lower pod rollers The flexible pod teeth are interlaced.

When working, put one end of the non-pod bean stalks in the clamping and conveying mechanism composed of the conveying chain and the clamping platen, and gradually enter between the upper and lower depod rollers with the movement of the conveying chain. Under the impact of the teeth, the bean pods fall off from the bean stalk one after another. During the falling process, the cleaning fan will blow off the fallen bean leaves, thereby completing the mechanized operation of soybean pod removal.

The further improvement of the utility model is that the de-clamping device is composed of first and second pairs of de-pod rollers distributed front and rear, and the included angle between the axis of the first de-pod roller and the conveying direction is smaller than that of the second de-pod roller. The angle between the axis of the pod roller axis and the conveying direction. In this way, the pod-free pods are struck by the flexible de-pod teeth twice in different directions during the conveying process, which can further improve the pod removal rate.

A further improvement of the utility model is that a vibrating cleaning screen is provided at the pod drop place at the bottom of the frame, and the pods dropped after pod removal can be screened out to keep full pods, eliminating the need for pods after pod removal. Manual screening to further improve the degree of mechanization.

The green soybean pod removing machine of present embodiment is as shown in Figure 1 and Figure 2, and one end of the upper part of frame 9 is collecting platform 3, and one side of frame is provided with the conveyor chain 1 that feeds along horizontal direction next to collecting platform 3 , the conveyor chain is composed of a driving sprocket 10 and a driven sprocket 11 respectively supported at both ends of the frame, and a chain 12 surrounding the two sprockets. A hook-shaped bar presser 14 is installed above the driven sprocket 11. The feeding port 2 is formed between the bar presser and the chain, and the clamping pressure plate 13 bearing the force of the spring 15 is installed on the frame above the conveying chain 1, and the chain 12 of the conveying chain and the clamping pressure plate 13 matched therewith constitute Clamping conveying mechanism.

The middle part of the conveying chain 1 is equipped with a rotary pod removal device, which is composed of the first and second pairs of upper and lower pod removal rollers 5, 5' and 6, 6' supported on the inner side of the clamping and conveying mechanism. The roller shaft of the pod roller has rubber pod removal teeth distributed at intervals and radially extending, and the angle between the axes of the first pair of pod rollers 5, 5' and the conveying direction is about 45° (45° ± 5°), The included angle between the axes of the second pair of pod removal rollers 6, 6' and the conveying direction is about 70° (70°±5°). The flexible pod teeth of the upper and lower pod rollers are interlaced.
