Description

Technical Field

[0001] This utility model relates to the field of sieve bed technology, and in particular to the stabilizing tie rod of the sieve bed seat of a gravity sorting machine. Background Technology

[0002] The sieve bed of the gravity sorting machine has a certain inclination angle in both the length and width directions, which we call the longitudinal inclination angle and the transverse inclination angle, respectively. During operation, the sieve bed vibrates back and forth under the action of the transmission mechanism. Seeds fall onto the sieve bed, and under the action of the airflow from the fan below, the seeds on the table are stratified, with the heavier seeds falling to the bottom of the material.

[0003] The patent specification with announcement number CN201310001687.6 discloses a screening machine filter screen shaft, which "includes a screen surface composed of a movable flange-type screen shaft (4), a movable screen bar-type screen shaft (5), and a spring-type screen shaft (24). The beneficial effects of this invention are: ensuring the screening particle size and solving the problem of material blockage inside the hollow filter screen shaft. Its application will realize many problems of screening machines such as strong impact resistance, high-efficiency screening, particle size assurance, no material blockage, iron removal, uniform material distribution, meeting two or more discharge particle sizes, and convenient maintenance and replacement of spare parts, which is another major breakthrough in the field of screening machines."

[0004] However, during the implementation of the relevant technology, the following problems were found with the screen shaft: During operation, the vibrating screen shaft of the screen bed is prone to wear due to its long-term reciprocating vibration. In traditional gravity separator screen beds, once the shims are damaged, the operation cannot continue and the whole machine needs to be repaired, resulting in poor stability. Therefore, a stabilizing tie rod for the screen bed of the gravity separator is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stabilizing tie rod for the sieve bed of a gravity sorting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stabilizing tie rod for a gravity sorting machine screen bed, comprising an inner plate of the screen machine, a placement groove being provided in the center of the front side of the inner plate of the screen machine, mounting plates being fixedly provided on both sides inside the placement groove, a vibrating screen shaft being inserted and connected between the two mounting plates, tensioning components being provided at both ends of the vibrating screen shaft, a detection component being provided on the surface of the placement groove, each of the two tensioning components comprising a tensioning wheel, a cavity, and a gasket, the two tensioning wheels being threadedly connected to one side of the two mounting plates respectively, the inner walls of the two tensioning wheels being provided with cavities matching the vibrating screen shaft, gaskets being fixedly provided inside the two cavities, toothed rings being fixedly provided on the surface of the two tensioning wheels, a first motor being fixedly provided at the top of one side of the two mounting plates, gears being fixedly connected to the drive shafts of the two first motors, and the two gears being meshed with the two toothed rings respectively.

[0007] As a further description of the above technical solution: the detection component includes a guide rail, a slide groove, several linkage rods, two bidirectional lead screws, four sliders, and four lead screw nuts. The guide rail is fixedly installed on the surface of the placement groove. The slide groove is opened at the top of the vibrating screen shaft. Linkage rods are fixedly installed on both sides of the inner wall of the guide rail and both sides of the inner wall of the slide groove. A bidirectional lead screw is fixedly installed between every two opposing linkage rods. Two sliders are slidably connected inside the guide rail and inside the slide groove.

[0008] As a further description of the above technical solution: pulleys are fixedly provided on the surfaces of both linkage rods, and a linkage belt is connected between the two pulleys. A second motor is fixedly provided on one side of the guide rail, and the drive shaft of the second motor is fixedly connected to one end of one of the linkage rods.

[0009] As a further description of the above technical solution: an infrared controller is fixedly provided at the bottom of each of the two sliders, and an infrared recognition module is fixedly provided at the top of each of the other two sliders.

[0012] This utility model has the following beneficial effects:

[0013] The gravity sorting machine screen bed seat stabilizing tie rod designed in this utility model uses a combination of shims, a first motor, gears, a gear ring, and tension wheels. Therefore, the distance between the two shims and the vibrating screen shaft can be adjusted by rotating the two tension wheels, thereby restoring the two shims to their vibrating screen limiting function. This effectively prevents the screen bed from becoming inoperable due to wear and aging of the shims, and effectively improves the service life and stability of the screen bed.

[0014] The gravity sorting machine screen bed stabilizing tie rod designed in this utility model, through the design of a second motor, a two-way lead screw, a linkage belt, a pulley, a lead screw nut, and a slider, etc., works together.

[0021] Reference Figure 1-4 The gravity sorting machine sieve bed seat stabilizing tie rod provided by this utility model includes a sieve machine inner plate 1, a placement groove 2 is provided in the middle of the front of the sieve machine inner plate 1, and mounting plates 3 are fixedly provided on both sides inside the placement groove 2. A vibrating sieve shaft 4 is inserted and connected between the two mounting plates 3. Tensioning components 5 are provided at both ends of the vibrating sieve shaft 4, and a detection component 6 is provided on the surface of the placement groove 2.

[0022] As a further implementation of the above technical solution: each of the two tensioning components 5 includes a tensioning wheel 51, a cavity 52 and a gasket 53. The two tensioning wheels 51 are respectively threaded to one side of the two mounting plates 3. The inner wall of each of the two tensioning wheels 51 is provided with a cavity 52 that matches the vibrating screen shaft 4. The gasket 53 is fixedly provided inside each of the two cavities 52.

[0023] Both tensioning wheels 51 are fixedly provided with toothed rings 7, and both mounting plates 3 are fixedly provided with first motors 8 on one side of the top. The drive shafts of the two first motors 8 are fixedly connected with gears 9. The two gears 9 are respectively meshed with the two toothed rings 7. When the vibrating screen shaft 4 is offset due to the wear of the two shims 53, the two infrared controllers 13 control the operation of the two first motors 8 respectively. After the two gears 9 rotate, they cause the two toothed rings 7 to rotate. Since the two tensioning wheels 51 are respectively threadedly connected to the two mounting plates 3, the distance between the two shims 53 and the vibrating screen shaft 4 can be adjusted by rotating the two tensioning wheels 51, so that the two shims 53 can restore the vibrating screen limiting function.

[0024] As a further implementation of the above technical solution: the detection component 6 includes a guide rail 61, a slide groove 62, several linkage rods 63, two bidirectional lead screws 64, four sliders 65 and four lead screw nuts 66. The guide rail 61 is fixedly installed on the surface of the placement groove 2. The slide groove 62 is opened at the top of the vibrating screen shaft 4. Linkage rods 63 are fixedly installed on both sides of the inner wall of the guide rail 61 and both sides of the inner wall of the slide groove 62. A bidirectional lead screw 64 is fixedly installed between every two opposing linkage rods 63. Two sliders 65 are slidably connected inside the guide rail 61 and inside the slide groove 62. Lead screw nuts 66, which are threadedly connected to the two bidirectional lead screws 64, are fixedly installed on the inner walls of several sliders 65.

[0025] Two of the linkage rods 63 are fixedly provided with pulleys 10, and a linkage belt 11 is connected between the two pulleys 10. A second motor 12 is fixedly provided on one side of the guide rail 61, and the drive shaft of the second motor 12 is fixedly connected to one end of one of the linkage rods 63.

[0026] Infrared controllers 13 are fixedly installed at the bottom of two sliders 65, and infrared recognition modules 14 are fixedly installed at the top of the other two sliders 65. The second motor 12 operates to rotate one of the bidirectional lead screws 64, and the linkage belt 11 drives the transmission between the two pulleys 10, so that the two bidirectional lead screws 64 rotate at the same speed. Then, through the cooperation of several lead screw nuts 66, each pair of opposite sliders 65 moves relative to each other. Thus, the detection range of the two infrared controllers 13 can be adjusted according to the vibration amplitude of the vibrating screen shaft 4.

[0027] As a further implementation of the above technical solution: the two first motors 8 are electrically connected to the two infrared controllers 13 respectively.

[0028] As a further implementation of the above technical solution: a switch panel 15 is fixedly provided on the surface of the mounting plate 3, and a motor switch is provided on the surface of the switch panel 15. The second motor 12 is electrically connected to the power supply through the motor switch.

[0029] Working principle: When using this utility model, the inner plate 1 of the screening machine is first fixedly installed inside the screening bed. Then, the vibrating motor driving the screening bed causes the vibrating screen shaft 4 to vibrate, thereby driving the screening mechanism at the top of the screening bed to vibrate. At the same time, two infrared controllers 13 respectively detect the position of both sides of the vibrating screen shaft 4. When the two infrared recognition modules 14 exceed the detection range of the two infrared controllers 13, the vibrating screen shaft 4 shifts due to the wear of the two shims 53. At this time, the two infrared controllers 13 respectively control the operation of the two first motors 8, and the rotation of the two gears 9 causes the two gear rings 7 to rotate. Due to the two tensioning wheels 5 1 is threadedly connected to two mounting plates 3 respectively, so the distance between the two shims 53 and the vibrating screen shaft 4 can be adjusted by rotating the two tensioning wheels 51, so that the two shims 53 can restore the vibrating screen limiting function. The second motor 12 can be used to rotate one of the bidirectional lead screws 64, and the linkage belt 11 can be used to drive between the two pulleys 10, so that the two bidirectional lead screws 64 rotate at the same speed. Then, through the cooperation of several lead screw nuts 66, each pair of opposite sliders 65 can move relative to each other, so that the detection range of the two infrared controllers 13 can be adjusted according to the vibration amplitude of the vibrating screen shaft 4.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
