Description

corn thresher

technical field

The invention relates to the field of corn processing, in particular to a corn thresher.

Background technique

Corn is rich in nutrition: it contains 74.8 grams of carbohydrates, 29 grams of protein, 16.6 grams of fat, and 6.9 grams of dietary fiber. It can be said that corn is the well-deserved No. 1 golden staple food.” According to nutrition experts, the “all-round nutrition” contained in corn is suitable for people of all ages. Its rich glutamic acid can promote brain development and is the best “benefit” for children. "Smart food"; the vitamin B group contained in it can regulate the nerves, and it is a "decompression food" suitable for white-collar workers; rich in linoleic acid and calcium, which can help regulate fat and lower blood pressure, and the high fiber content makes corn a good food The "scraping intestine food" can prevent middle-aged fat; in addition, the glutathione rich in corn is the most effective anti-cancer ingredient, and the rich vitamin E it contains can also help anti-aging and soften blood vessels. Corn is It is an important food crop and an important source of feed. It is rich in nutrients and is also the food crop with the highest total output in the world. However, due to the large size of corn, and only corn kernels can be eaten, in order to improve the storage efficiency of corn, it is necessary to Corn is threshed and stored. In the past, corn threshing was done manually, which was not only extremely inefficient, but also labor-intensive. Therefore, in order to solve the problem of corn threshing efficiency, corn threshers appeared on the market. Corn threshing The machine can quickly separate corn kernels and corn stalks, which is suitable for food processing factories to cooperate with quick freezing and corn canning manufacturers. However, in the operation of corn threshing, traditional corn threshers generally have threshing failures depending on the structure of the threshing device. If the corn kernels are clean or damaged, the remaining corn kernels on the corn stalks still need to be peeled manually after threshing by the net corn thresher, which increases the labor intensity of the operator; in addition, some corn kernels are damaged, resulting in unnecessary losses. , causing the waste of food and reducing the profits of enterprises.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a corn thresher with a simple structure, and the corn cobs are threshed by the swing rod. When the swing rod just contacts the corn, the inertia is relatively large, and the corn can be effectively Threshing: Since the threshing rod and the threshing rod make the gap match, after the threshing rod touches the corn, the corn kernels remaining on the corn cob are prevented from being damaged by the threshing rod, the threshing efficiency is high, the threshing effect is good, and unnecessary losses are avoided; in addition, The threshed corn kernels and corn stalks are discharged from different sides of the corn thresher, which is convenient for sorting and collecting.

A baffle is provided at the bottom of the end of the filter plate, and a corn stalk discharge port is provided between the baffle and the end of the box seat. , the bottom of the filter plate is provided with a corn grain discharge port; the cylindrical surface of the rotating shaft is distributed with a plurality of threshing rods, and the threshing rods are sleeved with a plurality of threshing rods, and the threshing rods are matched with the threshing rods, The rotating shaft is driven by a motor.

A further improvement solution of the present invention is that a sleeve is sleeved on the threshing rods between the throwing rods.

A further improvement of the present invention is that the throwing rod is connected to the threshing rod through a connecting sleeve, the outer diameter of the connecting sleeve is larger than the outer diameter of the casing, and the inner diameter of the connecting sleeve is larger than the diameter of the threshing rod.

A further improvement solution of the present invention is that the threshing rod is fixedly connected to the rotating shaft through a plurality of support plates that are uniformly distributed in the axial direction on the threshing rod.

A further improvement of the present invention is that the support plate is a regular polygon, the rotation axis passes through the geometric center of the support plate, and the number of sides of the regular polygon is equal to the number of threshing roots.

A further improvement of the present invention is that the cross section of the filter plate is an arc-shaped groove structure, and the filter plate is uniformly provided with filter holes, and the diameter of the filter holes is larger than that of corn kernels.

A further improvement solution of the present invention is that the top structure of the baffle matches the end of the filter plate.

A further improvement solution of the present invention is that the two ends of the rotating shaft are rotatably connected with the box seat through the bearing seat.

The further improvement of the present invention is that the corn stalk blanking port and the corn kernel discharge port are slope grooves, and the openings of the corn stalk blanking port and the corn kernel discharge port are respectively located on the two sides of the box base. side.

The beneficial effects of the present invention are:

First, the corn thresher of the present invention has a simple structure, and the corn cobs are threshed by the throwing rod. Cooperate, so after the rod touches the corn, the corn kernels remaining on the corn cob are prevented from being damaged by the rod, the threshing efficiency is high, the threshing effect is good, and unnecessary losses are avoided.

Second, in the corn thresher of the present invention, the threshed corn kernels and corn stalks are discharged from different sides of the corn thresher, which is convenient for sorting and collecting.
