Description

A kind of corn thresher

technical field

The utility model belongs to the technical field of agricultural equipment, in particular to a corn thresher.

Background technique

As we all know, the corn thresher is a widely used small-scale agricultural machinery, and it is a device that can separate corn kernels and stems. At present, in rural areas, corn threshers after drying are generally operated manually, which is laborious and inefficient. It hindered other labor arrangements, so corn threshers appeared, and the efficiency was improved, but the cleanliness of corn kernels was not high, and the corn kernels that came off had to be reprocessed, which affected farmers' labor arrangements and brought new benefits to their lives. Inconvenient, the existing corn thresher corn is fed from the feed port, the corn is impacted by the high-speed rotating rotor and the drum, the grains are separated by the sieve, and the corn cobs are discharged from the tail of the machine, but the corn is bumped forward in the drum During the moving process, the force cannot be well received, resulting in the uncleaned corncobs being easily discharged from the tail of the machine, thus affecting the cleaning rate and threshing efficiency, and the purpose of fully threshing cannot be achieved.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a corn thresher. The corn thresher has a simple structure, can effectively improve the cleaning rate and threshing efficiency of corn, and has a simple structure, which is convenient for farmers to popularize and use.

The purpose of this utility model is achieved by the following technical solutions:

The threshing device is arranged in the lower casing, including a rotating shaft, the rotating shaft is connected to both sides above the lower casing through bearings, one end of the rotating shaft is connected to the motor through a transmission device, and first triangular brackets are respectively sleeved on both sides of the rotating shaft and a second triangular bracket, the first triangular bracket is arranged on the rotating shaft on the connecting side of the lower casing and the slag discharge channel, the second triangular bracket is arranged on the other end of the rotating shaft in the lower casing, the corner end of the first triangular bracket is connected to the second The side ends of the two triangular supports are corresponding, and three threshing rods are fixedly connected between the three corner ends of the first triangular support and the three corner ends of the second triangular support respectively, and several threshing hammers are fixedly arranged on the threshing rods.

Further, the transmission device includes a driving wheel, a driven wheel, and a belt, the output shaft of the motor is connected to the driving wheel, the driving wheel is connected to the driven wheel through the belt, and the driven wheel is connected to one end of the rotating shaft.

Further, the corner end of the first triangular bracket corresponds to the center position of the side end of the second triangular bracket.

Further, the threshing hammers on the threshing rod decrease successively along the direction of the second triangular support.

Further, the housing is configured in a cylindrical shape and is fixed on the ground by four support rods.

Further, the installation position of the slag outlet channel is lower than the bottommost position of the lower casing.

Further, a cover is provided on the feed port.

Further, the rotational speed of the motor is 700 rpm.

Beneficial effects of the utility model: the corn cobs are fed from the feeding port of the upper casing, the motor is started, and the rotating shaft is driven to rotate, and then the three threshing rods are rotated, and the corn cobs are driven back and forth by the threshing hammer on the three threshing rods in the casing Collision and rotation, because the corner end of the first triangular bracket corresponds to the side end of the second triangular bracket, the three threshing rods are arranged obliquely, which prolongs the collision time of the corn cob in the housing, making it difficult for the corn cob to fall from the side of the lower housing. The outflow improves the cleaning rate. The threshed corn kernels enter the corn kernel collection box from the corn kernel outlet at the bottom of the lower casing, and the corn cobs flow out from the slag discharge channel connected to the side opening of the lower casing for storage.

The corn thresher has a simple structure, is easy to use, and has a cleaning rate as high as 98%, which avoids repeated threshing, thereby improving the threshing efficiency, and is convenient for widespread use by farmers.
