During the rice feeding stage, it is necessary for multiple people to cooperate to add rice into the specific gravity stone removing machine, which has an adverse effect on the rice feeding.

[0005] Therefore, a suction specific gravity stone removing machine is proposed, which has the advantage of being easy to feed from a high feeding port, thereby solving the problems in the above background art. Content of the Utility Model

[0006] The purpose of the utility model is to solve the defects existing in the prior art, and a suction specific gravity stone removing machine is proposed.

[0007] To achieve the above object, the utility model adopts the following technical solutions: a suction specific gravity stone removing machine, including a specific gravity stone removing machine body. The lower part of the specific gravity stone removing machine body is connected with a sieve body through a telescopic hose. A stone outlet is arranged on the left side wall of the sieve body, and a discharge port is arranged on the right side wall of the sieve body. A base is arranged below the specific gravity stone removing machine body, and an excitation motor is fixedly installed on the top surface of the base. The output end of the excitation motor is connected with the bottom of the sieve body through an eccentric mechanism. A feed nozzle is arranged on the right side of the upper part of the specific gravity stone removing machine body. A feeding box is welded on the right side of the top surface of the base, and a bearing plate is welded inside the feeding box. Two driving rollers are rotatably installed in the U-shaped opening on the surface of the bearing plate, and a conveyor belt is wound on the surfaces of the two driving rollers. A guide plate is welded at the lowest end of the U-shaped opening of the bearing plate. A driving motor is fixed at the upper edge of the bearing plate, and a driving belt is wound between the output end of the driving motor and the driving roller on the upper part of the bearing plate. A number of elastic feeding hoppers are equidistantly installed on the surface of the conveyor belt, and each elastic feeding hopper is composed of a movable plate and triangular telescopic fabrics stitched on both sides. And a swinging round rod is fixedly connected to the bottom of each elastic feeding hopper. A counterweight roller is rotatably installed on the upper part of the movable plate of the elastic feeding hopper. An arc groove is opened on the surface of the conveyor belt corresponding to the swinging round rod, and the arc groove and the swinging round rod are rotatably connected.

[0008] As a further description of the above technical solution: The guide plate is integrally in a V-shaped structure, and an arc part is arranged at the bottom of the guide plate. And the size of the arc part of the guide plate is adapted to the rotation track of the elastic feeding hopper in the area where the driving roller is located.

[0013] The utility model has the following beneficial effects:

[0014] In the present utility model, a feeding box is installed at the feeding nozzle of the specific gravity stoner body. As the driving motor drives the driving roller above the bearing plate to rotate under the action of the driving belt, the conveyor belt wound around the two driving rollers drives a number of elastic feeding hoppers on its surface to rotate. When the elastic feeding hopper approaches the guiding plate inside the feeding box, the open end of the elastic feeding hopper contacts the rice gathered on the guiding plate and expands. The movable plate rotates in the arc-shaped groove opened on the surface of the conveyor belt with the swinging round rod at its bottom as the basis, so that the triangular telescopic fabric is fully unfolded to form an elastic feeding hopper in the shape of a right triangle until the rice scooped up in the elastic feeding hopper is transferred to the feeding nozzle. Compared with the prior art, it is easier to feed materials at a higher feeding port. Secondly, when the elastic feeding hopper approaches the area of the feeding nozzle, the rice in the elastic feeding hopper is poured into the feeding nozzle, and under the action of gravity, the counterweight roller at the upper end of the movable plate is forced to rotate towards the conveyor belt direction, causing the triangular telescopic fabric to contract, avoiding the situation that the elastic feeding hopper contacts the feeding nozzle and affecting subsequent feeding.

In this device, the triangular telescopic fabric 18 is connected to the conveyor belt 14 to form a closed structure, which is convenient for scooping rice. The principle of the specific gravity stoner body 1 is a known technology in the prior art, and there are mature products, so no further explanation of its principle will be made. The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art.

The wiring diagram of the power element and the power supply are common knowledge in the art. And the present utility model is mainly used to protect the mechanical device, so the control mode and wiring layout will not be further explained in detail in the present utility model;

[0023] In one embodiment, the guide plate 9 is integrally in a V-shaped structure, and the bottom of the guide plate 9 is provided with an arc part. The size of the arc part of the guide plate 9 is adapted to the rotation trajectory of the elastic feeding hopper 15 in the area where the driving roller 11 is located. The guide plate 9 is welded to the inner wall surface of the feeding box 7. Through the setting of the guide plate 9, it is convenient for the aggregation of rice and easy for the elastic feeding hopper 15 to scoop. Through the arc part of the guide plate 9, it can make way for the elastic feeding hopper 15 on the surface of the conveyor belt 14.

[0024] In one embodiment, the expanded state of the elastic hopper 15 is in a right triangle structure, and the open end at the upper end of the elastic hopper 15 forms a rice loading opening. Through the setting of the elastic hopper 15, it can automatically "expand and contract" under the action of gravity, avoiding the situation that the elastic hopper 15 contacts the feed nozzle 10 and affecting the subsequent feeding.

Through the upper port, it is easy to receive the rice that fails to enter the feed nozzle 10. Through the rice feeding port, it is easy to feed the rice conveniently.

[0028] Working principle:

[0029] During use, first, the rice to be screened is fed into the feeding box 7. Then, the vibration motor 5 is started to drive the sieve body 2 of the specific gravity stoner body 1 to screen the rice, and with the cooperation of the fan, the rice and gravel are separated. During this process, as the drive motor 12 drives the drive roller 11 on the upper part of the carrier plate 8 to rotate under the action of the drive belt 13, the conveyor belt 14 wound around the two drive rollers 11 drives a number of elastic hoppers 15 on its surface to rotate. When the elastic hopper 15 approaches the guide plate 9 inside the feeding box 7, the open end of the elastic hopper 15 contacts the rice gathered on the guide plate 9 and expands, and the movable plate 17 rotates in the arc groove 20 opened on the surface of the conveyor belt 14 based on its bottom swing round rod 19, so that the triangular expandable and contractible fabric 18 is fully expanded to form a right triangle-shaped elastic hopper 15 until the elastic hopper 15 is completely filled with rice. When the elastic hopper 15 approaches the area of the feed nozzle 10, the rice in the elastic hopper 15 is poured into the feed nozzle 10, and under the action of gravity, the counterweight roller 16 at the upper end of the movable plate 17 is forced to rotate towards the conveyor belt 14, causing the triangular expandable and contractible fabric 18 to contract, avoiding the situation that the elastic hopper 15 contacts the feed nozzle 10 and affecting the subsequent feeding.
