Description

Technical Field

[0001] This utility model relates to the field of soil selection technology, specifically to a soil ecological compatibility selection device for highway greening. Background Technology

[0002] Hydroseeding is a mature and efficient application solution for highway slope greening. Its core is to create growing conditions for plants by artificially preparing a substrate. It is especially suitable for slopes with poor soil, rock, or steep slopes. Hydroseeding requires a large amount of soil as raw material. In order to make the soil and other organic matter into artificial soil that can be used by hydroseeding machines, the soil needs to be screened.

[0003] A Chinese utility model patent (CN205518540U) discloses a soil screening machine, comprising a support frame, a hopper, a transmission mechanism, a drive motor, and a screen cylinder. Both ends of the screen cylinder have circumferentially arranged annular support portions, each supported on the support frame by at least two rotatable rollers, the axes of which are parallel to the axis of the screen cylinder. The drive motor is connected to the screen cylinder via the transmission mechanism and can drive the screen cylinder to rotate. The inlet of the screen cylinder is connected to the outlet of the hopper. The screen cylinder's axis is horizontally aligned, and its circumferential surface is a screen mesh forming a frustum around the axis. The inlet of the screen cylinder is located at the smaller diameter end of the screen mesh. This utility model has advantages such as simple structure, easy assembly and disassembly, easy manufacturing, high screening efficiency, reasonable stress distribution, and long service life.

[0004] However, in implementing the relevant technology, the above-mentioned soil screening machine has the following problems: In the existing technology, the soil is turned over and rolled in the screen cylinder, so that the soil adhering to the screen falls off when it is high up to prevent the screen holes from being blocked. However, relying solely on the soil rotating and falling off when it is high up to prevent blockage is not effective, and the problem of soil blocking the screen holes still exists. Therefore, an ecologically adapted screening device for soil for highway greening is proposed. Utility Model Content

[0005] This utility model proposes an ecological adaptation screening device for topsoil used in highway greening, which solves the problem that the related technologies rely on soil rotation and falling from a height to prevent clogging, which has poor effect and still has the problem of soil clogging the screen holes.

[0006] The technical solution of this utility model is as follows: A highway greening soil ecological adaptation screening device, comprising:

[0007] A support frame and connecting plates fixedly installed on both sides of the inner wall of the support frame, with a screen cylinder rotatably connected through the center of the connecting plates;

[0008] A support frame is fixedly installed on one side of the inner wall of the bearing frame. Rotating rods are fixedly installed on both sides of the inner wall of the support frame. A connecting rod is rotatably connected to the outer side of the rotating rod. A rectangular block is fixedly connected to one end of the connecting rod.

[0009] Rotating component one is rotatably connected to the bottom of the rectangular block;

[0010] The power assembly is disposed through one side of the support frame.

[0011] Preferably, the power assembly includes a motor, a rotating shaft, and a cam. The motor is fixedly mounted on one side of the support frame, and the output end of the motor passes through the support frame and is fixedly connected to the rotating shaft. The cam is located on the outer side wall of the rotating shaft.

[0012] Preferably, a second rotating component is rotatably connected to both sides of the inner wall of the connecting rod, and the cam is in contact with the second rotating component.

[0013] Preferably, a threaded rod is fixedly installed on the top of the rectangular block, and counterweights are installed on the outer side walls of the threaded rod via threads.

[0014] Preferably, a second motor is fixedly installed on one side of the inner wall of the support frame, and a drive gear is fixedly connected to the output end of the second motor.

[0015] Preferably, a toothed ring is fixedly installed on the outer wall of the screen cylinder, and the drive gear is meshed with the toothed ring.

[0016] Preferably, a support plate is fixedly installed on the top of each of the support frames, and rotating parts are rotatably connected to both sides of the inner wall of the support plate. An annular groove is opened on the outer wall of each of the screen cylinders.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] The power assembly, connecting rod, rectangular block, and rotating component 1 are configured such that when the protruding part of the power assembly contacts the rotating component 2, it drives the connecting rod to rotate upward. When the protruding part of the power assembly does not contact the rotating component 2, the connecting rod drives the rectangular block to move downward under the action of gravity. The rectangular block drives the rotating component 1 to strike the outer wall of the screen cylinder. In conjunction with the rotation of the screen cylinder, the soil adhering to the screen cylinder is knocked off, thereby effectively preventing soil from clogging the screen holes.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1 - Figure 4 This utility model provides a highway greening soil ecological adaptation screening device, comprising:

[0027] The support frame 1 has connecting plates 18 fixedly installed on both sides of the inner wall of the support frame 1, and a screen cylinder 2 is rotatably connected through the center of the connecting plates 18;

[0028] Support frame 3 is fixedly installed on one side of the inner wall of bearing frame 1. Rotating rods 4 are fixedly installed on both sides of the inner wall of support frame 3. A connecting rod 5 is rotatably connected to the outer side of the rotating rod 4. A rectangular block 6 is fixedly connected to one end of the connecting rod 5.

[0029] Rotating component 7 is rotatably connected to the bottom of rectangular block 6;

[0030] The power assembly 8 is installed through one side of the support frame 3;

[0031] The power assembly 8 includes a motor 81, a rotating shaft 82, and a cam 83. The motor 81 is fixedly mounted on one side of the support frame 3. The output end of the motor 81 passes through the support frame 3 and is fixedly connected to the rotating shaft 82. The cam 83 is located on the outer side wall of the rotating shaft 82.

[0032] Rotating component 2 9 is rotatably connected to both sides of the inner wall of connecting rod 5, and cam 83 is in contact with rotating component 2 9;

[0033] When soil adheres to the screen cylinder 2, the output end of motor 81 drives the rotating shaft 82 to rotate, and the rotating shaft 82 drives the cam 83 to rotate. When the protruding part of the cam 83 contacts the rotating part 9, it drives the connecting rod 5 to rotate upward. When the protruding part of the cam 83 does not contact the rotating part 9, the rotating part 9 is a rotating wheel. Under the action of gravity, the connecting rod 5 drives the rectangular block 6 to move downward. The rectangular block 6 drives the rotating part 7 to strike the outer wall of the screen cylinder 2. The rotating part 7 is a rubber wheel in the prior art. It works with the rotation of the screen cylinder 2 to knock the soil adhering to the screen cylinder 2 off and prevent the soil from clogging the screen holes.

[0034] Specifically, a threaded rod 10 is fixedly installed on the top of the rectangular block 6, and counterweights 11 are installed on the outer side walls of the threaded rod 10 via threads.

[0035] Screw the counterweight 11 onto the outer wall of the threaded rod 10. Install an appropriate number of counterweights 11 according to actual needs and adjust the striking force of the rotating part 7.

[0036] Specifically, a motor 12 is fixedly installed on one side of the inner wall of the support frame 1, and a drive gear 13 is fixedly connected to the output end of the motor 12. A gear ring 14 is fixedly installed on the outer wall of the screen cylinder 2, and the drive gear 13 and the gear ring 14 are meshed together.

[0037] The output of motor 12 drives the drive gear 13 to rotate, and the drive gear 13 drives the screen cylinder 2 to rotate through the meshing gear ring 14, thereby screening the soil.

[0038] Specifically, a support plate 15 is fixedly installed on the top of the support frame 1, and rotating parts 16 are rotatably connected to both sides of the inner wall of the support plate 15. An annular groove 17 is opened on the outer wall of the screen cylinder 2.

[0039] Rotating component 3 16 is a rotating wheel. During the rotation of the screen cylinder 2, rotating component 3 16 rotates along the annular groove 17, which increases the stability of the screen cylinder 2 during the rotation process.

[0040] Working principle of this utility model: This utility model is a screening device for ecological adaptation of soil for highway greening. First, when using it, the soil to be screened is put into the hopper at the top of the support frame 1. The soil enters the screen cylinder 2 through the hopper. The output end of the motor 12 drives the drive gear 13 to rotate. The drive gear 13 drives the screen cylinder 2 to rotate through the meshing gear ring 14. Since the screen cylinder 2 is set at an inclination, the screened soil is discharged from the discharge hopper at the bottom of the support frame 1, and the stones in the soil are discharged through one end of the screen cylinder 2.

[0041] The output end of motor 81 drives the rotating shaft 82 to rotate. The rotating shaft 82 drives the cam 83 to rotate. When the protruding part of the cam 83 contacts the rotating part 9, it drives the connecting rod 5 to rotate upward. When the protruding part of the cam 83 does not contact the rotating part 9, the connecting rod 5 drives the rectangular block 6 to move downward under the action of gravity. The rectangular block 6 drives the rotating part 7 to strike the outer wall of the screen cylinder 2. In conjunction with the rotation of the screen cylinder 2, the soil adhering to the screen cylinder 2 is knocked off, preventing the soil from clogging the screen holes.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
