Description

A new wild soybean seed thresher

Technical Field

The utility model relates to the technical field of wild soybean processing, in particular to a novel wild soybean seed thresher.

Background technique

Wild soybean (Gycine soja Sjeb.et Zucc.) belongs to the soja subgenus of the Fabaceae family. It is also known as small falling beans, small falling bean vines, falling bean vines, mountain soybeans, wild soybeans, black beans, etc. Wild soybeans are annual twining herbs, 1-4 meters long. The stems and twigs are slender, and the whole body is sparsely covered with long brown stiff hairs. The leaves have 3 leaflets, up to 14 cm long, and the stipules are ovate-lanceolate, acute, and covered with yellow soft hairs. The inflorescence is usually short in racemes. The seeds are slightly constricted, oval, and easy to crack when dry. There are 2-3 seeds, which are oval, slightly flat, 2.5-4 mm long, 1.8-2.5 mm wide, brown or black, and the flowering period is July-August, and the fruiting period is August-October. Except for Xinjiang, Qinghai and Hainan, it is distributed throughout the country.

Cultivated soybeans are the product of wild soybeans that have been domesticated and selected. Wild soybeans have extremely high protein content, and the high-protein gene can be transferred to cultivated soybeans through conventional hybrid breeding. Wild soybeans have strong adaptability and resistance to the environment, so in addition to being cultivated as forage and feed, wild soybeans also play an important role in soybean breeding.

In the research and experimental planting of wild soybeans, when threshing the wild soybean seeds, since the wild soybean pods and beans are smaller than those of cultivated soybeans, it is impossible to use the thresher for threshing the wild soybeans, and manual threshing is required. The manual threshing method requires putting the dried wild soybean pods into a sack or cloth bag, and using a mallet, hammer or other hard object to gently tap the bag to crack the pods and release the beans, and then taking the beans out of the pods. The above manual threshing method has high labor intensity, and the threshing process is cumbersome, which reduces the threshing efficiency.

At the same time, a fan 4 is fixedly connected to one side of the threshing box 1, and the air outlet end of the fan 4 is connected to the top side of the threshing cylinder 2 to blow the bean pods inside the threshing cylinder 2. A slag discharge cylinder 5 is fixedly connected to the top end of the threshing cylinder 2 away from the fan 4, and the other end of the slag discharge cylinder 5 penetrates the threshing box 1 and extends to the outside of the threshing box 1. The bean pods blown by the fan 4 enter the inside of the slag discharge cylinder 5 and are then discharged to the outside of the threshing box 1. A hanging ring 501 is also fixedly connected to the outer wall of the slag discharge cylinder 5, and a hollow collecting bag is hung on the hanging ring 501 to collect the discharged bean pods to avoid splashing of the bean pods.

As shown in Figures 1 and 2, the bottom of the threshing cylinder 2 is fixedly connected with two groups of blocks 201, and the sieve plate 6 slides inside the two groups of blocks 201 and is attached to the outer wall of the threshing cylinder 2. The sieve plate 6 is installed on the two groups of blocks 201 and is attached to the inner wall of the threshing cylinder 2 for use, so that the sieve plate 6 can be quickly disassembled and installed, and the sieve plate 6 or the inside of the threshing cylinder 2 can be cleaned and maintained. Racks 601 are provided on the outer walls at both ends of the sieve plate 6. Two groups of drive rods 8 are rotatably connected inside the threshing box 1. The two groups of drive rods 8 are attached to the outer wall of the threshing cylinder 2. The walls are fixedly connected with half gears 801, and the two groups of half gears 801 are staggered and meshed with the two groups of racks 601, and the two groups of half gears 801 are driven to rotate by the driving rod 8, and the two groups of half gears 801 are staggered and meshed with the two groups of racks 601, so that the screen plate 6 can slide back and forth left and right on the block 201, and the beans on the screen plate 6 can be screened out through the sieve holes more quickly through the sliding of the screen plate 6, thereby improving the screening efficiency and avoiding the accumulation of beans on the screen plate 6.
