Description

Technical Field

[0001] The utility model belongs to the technical field of grading screens, in particular to a vibrating grading screen. Background Art

[0002] The vibrating grading screen is a machine that uses a vibrating screen surface to grade a mixture of particles of different sizes according to particle size. The vibrating grading screen adopts the principle of vibrating screening and ensures the grading effect through reasonable screen surface inclination angle and screen mesh aperture. It is widely used in the screening and grading of raw materials and finished products in various industries such as grain, food, chemical industry, and sugar making. In real life, vibrating grading screens are often used for screening in the process of cumin processing. However, since most vibrating grading screens are not equipped with a feeding mechanism, workers need to manually add materials multiple times during screening. The whole process is time-consuming and labor-intensive, which not only increases the work intensity of workers, but also easily causes over-feeding, thus affecting subsequent screening.

[0003] A Chinese patent document (application announcement number CN214718338U) discloses a vibrating grading screen, which includes a grading discharging area, a vibration area, a feeding device, a dust-proof discharging device, a vibration connecting rod, a horizontal base, and an inclined base. The bottom end of the grading discharging area is provided with a dust-proof discharging device, the bottom ends of the grading discharging area and the vibration area are respectively connected with a vibration connecting rod, the bottom end of the vibration connecting rod is connected with a horizontal base, the bottom surface of the horizontal base is connected to the top surface of the inclined base, and the top surface of the inclined base is at an angle of fifteen degrees to the horizontal plane.

[0004] It can be seen that the patent document cited above also has the same problem. It lacks a feeding mechanism, and workers are required to manually add materials multiple times during screening. The whole process is time-consuming and labor-intensive, which not only increases the workers' workload, but also easily leads to over-feeding, thus affecting subsequent screening.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a vibrating grading screen, comprising a screening box for vibrating grading screening, a feed pipe is connected to the top of the screening box, a storage box is connected to the top of the feed pipe, a fixed plate is installed on one side of the storage box, a feeding assembly is provided on the top of the fixed plate, and a stirring assembly is provided on the top of the storage box;

[0007] The feeding assembly includes a first motor, a rotating shaft is installed at the output end of the first motor, a first transmission gear is installed at the bottom end of the rotating shaft, a second transmission gear is meshed with the tooth edge of the first transmission gear, a connecting shaft is installed on the inner wall of the second transmission gear, a connecting rod is installed at the bottom end of the connecting shaft, a shift rod is installed at the bottom end of the connecting rod, a cross bar is provided on the outer wall of the shift rod, a partition is installed on one side of the cross bar, the outer wall of the partition passes through the feed pipe, and a feeding trough is opened at the top end of the partition.

[0008] As a preferred embodiment, the stirring assembly includes a transverse plate, a second motor is installed on the top end of the transverse plate, and a stirring shaft is installed on the output end of the second motor.

[0009] As a preferred embodiment, an observation window for observing the internal situation of the storage box is embedded on one side of the storage box, and support rods are installed on the four sides of the bottom end of the storage box, and the bottom ends of the four support rods are fixedly connected to the top end of the screening box.

[0010] As a preferred embodiment, the top end of the connecting shaft is connected to the bottom end bearing of the fixing plate.

[0011] As a preferred embodiment, a fixing groove is provided at the top end of the cross bar, and the inner side of the fixing groove is slidably connected to the outer wall of the lever.

[0012] As a preferred embodiment, two material blocking blocks are installed on the inner wall of the feed pipe near the top of the partition, and the top of the material blocking blocks is inclined.

[0013] As a preferred embodiment, during the movement of the partition, the outer side of the partition is always located in the inner wall of the feed pipe.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The vibrating grading screen benefits from the design of the first motor, the partition, the feed pipe and the storage box. The first motor drives the first transmission gear to rotate, and the first transmission gear rotates the second transmission gear intermittently, thereby driving the partition to intermittently reciprocate left and right. When the feed trough on the partition moves into the feed pipe, the storage box starts to unload materials. When the feed trough moves out of the feed pipe, the storage box stops unloading materials. In this way, equal amounts of materials can be automatically loaded. The whole process saves time and effort, not only reduces the work intensity of workers, but also avoids excessive feeding, thereby not affecting subsequent screening.

[0016] By arranging a stirring assembly at the top of the storage box, when the material to be screened is added into the storage box, the stirring assembly is turned on and the inside of the storage box is stirred by the stirring assembly, thereby avoiding the material jamming when the material in the storage box is discharged, thereby ensuring the normal discharge of the material.

When the loading trough 510 on the partition 509 enters the feed pipe 2, the storage box 3 loads the screening box 1. When the loading trough 510 moves out of the feed pipe 2, the loading is stopped at this time. In this way, the loading can be automatically carried out in equal amounts. The whole process saves time and effort, reduces the work intensity of workers, and avoids excessive feeding, thereby not affecting subsequent screening.

The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0036] How it works

[0037] The storage box 3 is filled with cumin to be screened, and then the second motor switch is turned on. The second motor 602 drives the stirring shaft 603 to rotate, so that the inside of the storage box 3 can be stirred, thereby avoiding the jamming of the cumin in the storage box 3 when the cumin is discharged. Next, the first motor switch is turned on, and the first motor 501 drives the first transmission gear 503 to rotate through the rotating shaft 502. The rotation of the first transmission gear 503 drives the second transmission gear 504 to rotate intermittently. The rotation of the second transmission gear 504 drives the connecting rod 506 to rotate through the connecting shaft 505, and then drives the cross bar 508 to move left and right through the shifting rod 507. The second transmission gear 504 reciprocates intermittently left and right under the action of the cross bar 508, and the movement of the partition 509 drives the partition 509 to reciprocate intermittently left and right. When the loading chute 510 at the top of the partition 509 moves into the feed pipe 2, the cumin in the storage box 3 enters the screening box 1 through the loading chute 510. When the loading chute 510 moves out of the feed pipe 2, the partition 509 blocks the inside of the feed pipe 2, and the storage box 3 stops unloading. In this way, the material can be automatically loaded in equal amounts. The whole process saves time and effort, not only reduces the work intensity of the workers, but also avoids excessive feeding, thereby not affecting the subsequent screening.
