Description

A belt type material cleaning machine

technical field

The utility model relates to a material cleaning machine, in particular to a belt-type material cleaning machine suitable for peanuts, belonging to the technical field of agricultural machinery.

Background technique

Belt cleaners are often used for sorting granular materials such as soybeans and mung beans. When working, according to the difference in material friction coefficient and rolling characteristics, half of the materials such as soybeans and mung beans can be removed to improve the quality of seeds.

After peanut seeds are mechanically dehulled, most of the broken seeds are half-grained. In order to ensure the quality of the seeds, it is also necessary to remove the half-grained peanut seeds after dehulling. However, as far as the applicant knows, there is no special peanut half-seed removal equipment on the market at present. In order to improve the sorting efficiency, sometimes soybeans and mung beans have to be used to remove peanut half-seeds with belt-type cleaning equipment.

Because the physical characteristics of peanut seeds are very different from those of soybeans and mung beans, most peanut seeds have an arc-shaped rugby ball shape with good rolling properties, and some intact peanut seeds have flat outer surfaces with poor rolling properties. The movement characteristics of the upper run are similar to that of a half peanut. Usually, its flat surface is in contact with the belt of the belt cleaning machine and remains relatively still, so it is mistakenly selected as a half seed, and the sorting loss is relatively large. Therefore, how to disturb the entire cleaning mechanism to improve the accuracy of seed selection is a technical problem that needs to be solved urgently.

Utility model content

The purpose of the utility model is to provide a belt-type material cleaning machine that can effectively separate half-grained peanuts and whole-grain peanut seeds with a flat surface, so as to avoid wrong selection of intact peanut seeds and significantly reduce the loss of sorting.

The applicant has found through experimental research that although the whole peanut seeds with a flat surface are usually relatively stationary on the flat belt like half seeds, they still have rolling characteristics that half peanuts do not have under certain conditions. If the belt in the machine is properly disturbed, this kind of peanut will show its rolling characteristics, so as to realize the correct sorting. On the basis of this research, the applicant proposes a belt-type material cleaning machine of the present invention: it includes a drive roller supported on the frame at both ends of the length direction and axially inclined, and the drive roller is surrounded by a flat belt; The feeding end of the belt in the moving direction is connected to the feeding port of the feeding hopper, and a miscellaneous box is placed under the other end; the lower side of the flat belt is equipped with a discharge box; it is characterized in that: one of the driving rollers One end of the cam is equipped with a cam, and the cam and one end of the torsion bar hinged on the frame form a cam pair. The pin constitutes a moving pair, and the torsion bushing is fixedly connected with the disturbance shaft, and the disturbance shaft is supported on the frame with the axis perpendicular to the direction of motion of the flat belt, and the beating plates under the flat belt are fixed at circumferential intervals.

The technical scheme that the utility model is further limited is:

Further, the frame is provided with a torsion bar mounting bracket, and the torsion bar is movably mounted on the bracket through a pin shaft and a torsion spring.

Further, the frame is provided with a long hole, and the torsion bar mounting bracket is installed in the long hole through a fastener.

Further, three adjustment mounting holes are opened on the torsion bar.

Further, support bases are fixedly installed at both ends of the frame, and both ends of the disturbance shaft are supported on the support bases.

Further, the drive rollers are multi-layered, and each layer is installed parallel to each other on the frame.

Further, each layer of drive rollers is provided with a feeding port, and the feeding box is uniformly distributed.

Further, the discharge box includes a whole-grain discharge box and a whole-semi-round grain mixing discharge box, and the outlets of the whole-grain discharge box and the whole-semi-round grain mixing discharge box are located on both sides of the disturbance axis.

Further, there are at least three beating plates installed on the disturbance shaft.

The working principle of the utility model is: when the equipment is in operation, the peanut seeds fall on the flat belt through the feeding device. Since the flat belt is at a certain angle with the horizontal plane, the peanut seeds with a relatively regular shape will be lowered during the operation of the flat belt. One side of the peanut rolls and falls into the hopper of the whole seed to be sorted; and the half peanut seed will move to the other end with the flat belt because of its contact with the flat belt, and the half peanut seed will fall into the miscellaneous box , to achieve selection. Peanut seeds with a flat appearance will intermittently beat the flat belt due to the disturbance mechanism mainly composed of torsion bars, disturbance shafts and beating plates, and the disturbance will show rolling characteristics. Like regular-shaped peanut seeds, they will run on the flat belt. Roll towards the lower side during the process, and then fall into the whole semi-round grain hopper to realize the second sorting.

The beneficial effects of the utility model are: the utility model has simple structure principle, low cost and high work efficiency. By adding a disturbing mechanism, the accuracy of seed selection is improved, the loss of sorting is reduced, one machine with multiple functions is realized, and the utilization rate of equipment is improved. At the same time, the position of the support point of the torsion bar can be easily changed by adjusting the position of the bracket, so as to realize the adjustment of the rotation angle of the disturbance axis, thereby realizing the adjustment of different disturbance degrees required by different peanut varieties.

Working principle and process of the present utility model are:

When the equipment is in operation, peanut seeds (kernels) 17 enter the belt 11 through the feeding device, and the belt 11 is at a certain angle to the horizontal plane, and the peanuts 17 with a relatively regular shape roll on the belt sorting machine belt, toward the direction of the arrow shown in Figure 3. The A direction rolls into the hopper to realize the sorting of such seeds. During the movement of half peanut seeds (kernels), one side of the seed plane is in contact with the belt of the belt sorter. Due to the large friction force, it remains relatively stationary with the belt, and moves along with the belt in the direction shown by arrow B in the figure, so as to realize half peanut seeds (kernels). Peanut seeds (kernels) are sorted. During this process, some intact but flat peanuts will lie flat on the belt and move with the belt like a half peanut, so they will be mistakenly selected as half peanuts.
