Description

Technical Field

[0001] The utility model relates to the technical field of vibration screening devices, in particular to a grain sorting vibration device. Background Art

[0002] Grains refer to grain particles, such as corn kernels, rice or beans. Grain crops need to be screened during processing to separate the grains into different sizes for easy subsequent processing and storage. This is also one of the common processing methods nowadays.

[0003] Grains are basically screened using a vibrating screen. The equipment is vibrated by a vibrating motor, and the vibration drives the grains inside the equipment to jump on the filter and move at the same time. Qualified grains will fall from the filter holes, and unqualified grains will be left behind. This method requires the vibrating motor to work continuously without stopping, which increases energy consumption. For this reason, a grain sorting vibration device is proposed. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: a grain sorting vibration device includes a base, two bases are provided, the top side walls of the two bases are fixedly connected to springs, the end of the spring away from the base is fixedly connected to a connecting plate, the top side wall of the connecting plate is rotatably connected to a filter plate, a rotating shaft is rotatably connected between the two opposite side walls of the base, a cam is fixedly connected in the middle of the rotating shaft, and a roller is rotatably connected in the middle of the side wall of the end of the cam away from the rotating shaft.

[0005] As an optimal technical solution of the present invention, a striking plate is fixedly connected to the bottom side wall of the filter plate and at a position opposite to the cam. The side wall of the striking plate away from the base is an inclined structure, and the roller rotates and fits with the bottom side wall of the striking plate.

[0006] As an optimal technical solution of the present invention, a side vertical plate is fixedly connected to one side edge of the top of the two bases, a knob is rotatably connected to the middle of the side vertical plate away from one end of the base, and a sliding groove is provided in the middle of the side wall of the side vertical plate opposite to the spring.

[0008] As a preferred technical solution of the present utility model, a motor is detachably embedded in one of the bases, a telescopic limit rod is fixedly connected to the middle of the top side wall of the base, the spring is sleeved on the telescopic limit rod, the top of the telescopic limit rod is fixedly connected to the bottom side wall of the connecting plate, and the output end of the motor is detachably connected to one end of the rotating shaft.

[0009] The utility model has the following advantages: the cam is driven by the motor to rotate the rotating shaft, and when the cam rotates with the roller to fit the impact plate, the filter plate will be pushed upward as the cam continues to move, thereby stretching the spring. At this time, the cam continues to move and finally separates from the bottom of the impact plate. The lifted filter plate suddenly falls after losing its supporting force, which will also cause the spring to contract. The elastic characteristics of the spring will drive the filter plate to shake up and down at high frequency, thereby realizing the function of the filter plate vibration, thereby driving the grains on the filter plate to jump and displace to achieve the screening effect. In this way, the traditional vibration motor can be abolished, and the existing motor does not need to operate at high frequency, thereby reducing energy consumption. In addition, the high-frequency vibration of the filter plate can be achieved through the cooperation of the spring and the cam, thereby ensuring the vibration screening effect.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to Figure 1-3 The grain sorting vibration device of the present invention includes a base 1. There are two bases 1. The top side walls of the two bases 1 are fixedly connected to springs 6. The end of the spring 6 away from the base 1 is fixedly connected to a connecting plate 9. The top side wall of the connecting plate 9 is rotatably connected to a filter plate 18. A rotating shaft 2 is rotatably connected between the opposite side walls of the two bases 1. A cam 3 is fixedly connected in the middle of the rotating shaft 2. A roller 4 is rotatably connected in the middle of the side wall of the end of the cam 3 away from the rotating shaft 2.

[0016] The bottom side wall of the filter plate 18 is fixedly connected to the impact plate 5 at a position opposite to the cam 3. The side wall of the impact plate 5 away from the base 1 is an inclined structure. The roller 4 rotates and fits with the bottom side wall of the impact plate 5. A side vertical plate 7 is fixedly connected to one side edge of the top of the two bases 1. A knob 8 is rotatably inserted and connected in the middle of the side vertical plate 7 away from the end of the base 1. A sliding groove 11 is provided in the middle of the side wall of the side vertical plate 7 opposite to the spring 6.

[0017] The technical effect of this solution is as follows: the motor 16 in the start-up base 1 drives the rotating shaft 2 to rotate. As the rotating shaft 2 rotates, the cam 3 can be driven to rotate, and as the cam 3 rotates, it will hit the lower side wall of the impact plate 5, and because the roller 4 is connected to one end of the cam 3, when the cam 3 rotates, it will also drive the roller 4 to rotate on the bottom side wall of the impact plate 5, thereby lifting the filter plate 18. When the roller 4 moves away from the bottom side wall of the impact plate 5, the filter plate 18 will fall suddenly, and the spring 6 that was originally lifted and stretched will also retract. The spring 6 that retracts by inertia will also extend. In this way, the function of driving the filter plate 18 to vibrate at high frequency is achieved, so there is no need for the vibration motor 16 to run at high frequency, and the motor 16 currently used does not need to run at high frequency for a long time. It only needs to adjust the operating frequency of the motor 16 according to actual needs, which can effectively reduce energy consumption and improve application flexibility.

[0018] A screw 12 is rotatably connected in the slide groove 11, and a slider 13 is threadedly sleeved on the screw 12. One end of the slider 13 is fixedly connected to a movable baffle 14, and the top side wall of the side plate 7 opposite to the spring 6 is fixedly connected to a fixed baffle 15. One end of the knob 8 extends into the slide groove 11 and is detachably connected to the top of the screw 12. A follower plate 10 is set between the fixed baffle 15 and the movable baffle 14. The follower plate 10 is fixedly connected to one side wall of the connecting plate 9 through one end thereof. A motor 16 is detachably embedded in one of the bases 1, and a telescopic limit rod 17 is fixedly connected to the middle of the top side wall of the base 1. The spring 6 is sleeved on the telescopic limit rod 17, and the top of the telescopic limit rod 17 is fixedly connected to the bottom side wall of the connecting plate 9. The output end of the motor 16 is detachably connected to one end of the rotating shaft 2.

[0019] The technical effect of this solution is as follows: in order to adjust the vibration frequency of the filter plate 18, a fixed baffle 15 and a movable baffle 14 are set on the side wall opposite to the side plate 7 and the follower plate 10, and the follower plate 10 fixed on the side wall of the connecting plate 9 is set between the fixed baffle 15 and the movable baffle 14. When the filter plate 18 vibrates, it will also drive the connecting plate 9 and the follower plate 10 to shake synchronously. By adjusting the position of the movable baffle 14, the movable range of the follower plate 10 can be adjusted, thereby adjusting the frequency of vibration.

[0020] Specifically, when the present invention is used, the grains are placed in the filter plate 18, and then the motor 16 is started to drive the rotating shaft 2 to rotate. As the rotating shaft 2 rotates, the cam 3 rotates synchronously, and finally the roller 4 is pressed against the bottom side wall of the impact plate 5. As the cam 3 continues to rotate, the filter plate 18 is pushed upward, and the spring 6 is stretched upward and stretched. When the roller 4 separates from the bottom side wall of the impact plate 5 and the filter plate 18 and the spring 6 suddenly fall back, but due to the characteristics of the spring 6, it will stretch after falling back, thereby driving the filter plate 18 to continuously shake up and down, thereby realizing the function of high-frequency vibration. Because the vibration motor 16 is no longer used, the motor 16 used now can adjust the operating frequency according to actual needs, thereby reducing energy consumption, and according to actual needs, the knob 8 is turned to drive the screw 12 to rotate, and the slider 13 and the movable baffle 14 are driven to move through the threaded connection relationship, thereby adjusting the distance between the movable baffle 14 and the fixed baffle 15, so that the activity space of the follower plate 10 can be adjusted, thereby adjusting the vibration frequency of the filter plate 18 to increase the flexibility of equipment application.
