Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a soil stabilizer spraying device for roadbed construction. Background Technology

[0002] In roadbed construction, spraying soil stabilizers is a technique that improves soil properties through chemical and physical processes. The active ingredients in the stabilizer react chemically with minerals in the soil to generate cementing substances such as calcium silicate and calcium aluminate, binding loose soil particles into a cohesive whole, forming a stable system similar to a "plate structure." This structure can significantly improve the compressive strength and bearing capacity of the roadbed, reducing roadbed settlement and deformation. Stabilizers are typically applied to the roadbed using spraying devices; however, these devices suffer from problems, as mentioned in the patent publication CN 222358648 U, "An Adjustable Spraying Device for Soil Stabilizer in Roadbed Construction." The nozzles are usually fixed, only covering a narrow area directly below the nozzle or in a limited direction, resulting in a limited spraying range and low efficiency. During equipment movement, it is difficult to efficiently cover more soil, and comprehensive spraying cannot be achieved in a short time. Utility Model Content

[0003] This invention addresses the problem of fixed nozzles and small spraying range in spraying devices used for spraying soil stabilizers. It provides a soil stabilizer spraying device for roadbed construction that allows for adjustment of the spraying range while the stabilizer is being sprayed.

[0004] To solve the above problems, the technical solution of this utility model is:

[0005] A soil stabilizer spraying device for roadbed construction includes a shell, a drive plate, and a column. Rotary rods are rotatably connected to both the left and right sides of the shell. Rollers extend from both ends of each rotary rod and are connected to the shell. The drive plate is slidably located within the left side of the shell. When the rotary rod on the left rotates, it drives the drive plate to reciprocate left and right via a transmission component. A groove is recessed on the top surface of the drive plate, and a loop frame, driven to move left or right by an electric push rod, is located within the groove. Multiple teeth are provided on the inner rear side of the loop frame. The column is rotatably connected to the top plate of the shell opposite the opening of the groove. A circular gear with meshing teeth is connected to the lower end of the column. A spray pipe is fixed to the upper end of the column, and multiple nozzles are connected to the left side of the spray pipe. A storage tank for pumping the stabilizer into the spray pipe is located on the upper part of the shell.

[0006] Furthermore, the transmission component includes a through hole and teeth. The drive plate is sleeved on the left rotating rod through the through hole. Multiple teeth are provided on both the upper and lower surfaces of the through hole. A sector gear is connected to the left rotating rod. When the protrusion of the sector gear faces upward, it meshes with the teeth on the upper side of the through hole. When the protrusion faces downward, it meshes with the teeth on the lower side of the through hole.

[0007] Furthermore, when the sector gear protrudes upward and its left end is disengaged from the upper tooth 2, there is a gap between the left end of the through hole and the sector gear, and a gap between the spur gear and the left end of the loop frame; when the sector gear protrudes downward and its right end is disengaged from the lower tooth 2, there is a gap between the right end of the through hole and the sector gear, and a gap between the spur gear and the right end of the loop frame.

[0008] Furthermore, the electric push rod is fixed to the right end of the groove, and the piston end of the electric push rod is connected to the right end of the loop frame to the left; there is a gap between the front end of the spherical gear and the front side plate of the loop frame.

[0009] Furthermore, the liquid storage tank is fixed to the top of the shell on the right side of the column, and the left side plate of the liquid storage tank is provided with an input end that connects to the pump body inside the liquid storage tank. The output end of the pump body is connected to the spray pipe through a connecting pipe. The top plate of the liquid storage tank is provided with an injection hole.

[0010] Furthermore, the distances from the front and rear ends of the spray pipe to the column are the same, and support rods are fixed to the front and rear parts of the outer bottom of the spray pipe. The lower end of each support rod is connected to a ball bearing that contacts the outer top surface of the housing.

[0011] The beneficial effects of this utility model through the above technical solution are as follows:

[0012] When the curing agent inside the spray pipe of this utility model is sprayed onto the soil, it pulls the utility model to move. Under the action of the left rotating rod, it can drive the drive plate to move to the right or left, and then drive the spray pipe to rotate clockwise or counterclockwise through the column. The oscillating spray pipe can increase the spraying range of the curing agent and achieve full spraying of the curing agent in a short time.

[0013] Furthermore, when the curing agent is sprayed while the device is stationary, the electric push rod can also drive the spray pipe to rotate clockwise or counterclockwise via the loop frame, which can also increase the spraying range of the curing agent and make it convenient to use.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1-5 As shown, a soil stabilizer spraying device for roadbed construction includes a housing 1, a drive plate 2, and a column 3. The housing 1 is a rectangular box with its lower opening sealed by a lower side plate. Rotating rods 4 are rotatably connected to both the left and right sides of the housing 1. Each rotating rod 4 is a round rod, and rollers 5 extend out of the housing 1 at both ends. The drive plate 2 is slidably disposed inside the left side of the housing 1. The drive plate 2 is a rectangular plate that slides against the inner side of the housing 1. When the rotating rod 4 on the left side rotates, it drives the drive plate 2 to reciprocate left and right via a transmission component. The top surface of the drive plate 2 has a recessed groove 6, which is an elongated groove along the length of the drive plate 2. A rectangular groove 6 is provided, and a loop frame 7 is provided in the groove 6. The loop frame 7 is a rectangular frame whose front and rear outer sides slide in contact with the groove 6 respectively. The upper end of the loop frame 7 slides in contact with the inner top surface of the housing 1 and the lower end slides in contact with the inner bottom of the groove 6. The rear inner surface of the loop frame 7 is provided with multiple teeth 10. The column 3 is rotatably connected to the top plate of the housing 1 opposite to the opening of the groove 6. The lower end of the column 3 is connected to a spur gear 11 that meshes with the teeth 10. The upper end of the column 3 is fixed with a spray pipe 12. The left side of the spray pipe 12 is connected to multiple nozzles 13. The upper part of the housing 1 is provided with a liquid storage tank 14 for pumping curing agent into the spray pipe 12.

[0022] The transmission component includes a through hole 15 and teeth 16. The drive plate 2 is sleeved on the left rotating rod 4 through the through hole 15. The through hole 15 is a rectangular hole that passes through the front and rear sides of the drive plate 2. Multiple teeth 16 are provided on the upper and lower surfaces of the through hole 15. A sector gear 17 is connected to the left rotating rod 4. When the protrusion of the sector gear 17 faces upward, it meshes with the teeth 16 on the upper side of the through hole 15. When the protrusion faces downward, it meshes with the teeth 16 on the lower side of the through hole 15. Multiple teeth 16 on the same side of the through hole 15 are spaced apart along the length of the through hole 15.

[0023] When the sector gear 17 protrudes upward and its left end is disengaged from the upper tooth 16, there is a gap between the left end of the through hole 15 and the sector gear 17, and a gap between the spur gear 11 and the left end of the loop frame 7; when the sector gear 17 protrudes downward and its right end is disengaged from the lower tooth 16, there is a gap between the right end of the through hole 15 and the sector gear 17, and a gap between the spur gear 11 and the right end of the loop frame 7.

[0024] The electric push rod 9 is fixed to the right end of the groove 6, and the piston end of the electric push rod 9 is connected to the right end of the loop frame 7 with its left side facing the groove. There is a gap between the front end of the spherical gear 11 and the front side plate of the loop frame 7.

[0025] The liquid storage tank 14 is fixed to the top of the shell 1 on the right side of the column 3. The left side plate of the liquid storage tank 14 is provided with an input end that connects to the pump body 18 inside the liquid storage tank 14. The output end of the pump body 18 is connected to the spray pipe 12 via a connecting pipe 20. The top plate of the liquid storage tank 14 is provided with an injection hole 19. The right side of the liquid storage tank 14 is provided with a handle.

[0026] Limiting rings 21 are fixedly fitted on the columns 3 on the upper and lower sides of the housing 1, and the two limiting rings 21 slide in contact with the upper and lower surfaces of the top plate of the housing 1 respectively.

[0027] When the piston end of the electric push rod 9 is extended to its limit, there is a gap between the U-shaped frame 7 and the left end of the groove 6; when the piston end of the electric push rod 9 is retracted to its limit, there is a gap between the U-shaped frame 7 and the right end of the groove 6.

[0028] The distances from the front and rear ends of the spray pipe 12 to the column 3 are the same. Support rods 22 are fixed to the front and rear parts of the outer bottom of the spray pipe 12. The lower end of each support rod 22 is connected to a ball bearing 23 that contacts the outer top surface of the housing 1. The two support rods 22 can improve the stability of the rotation of the spray pipe 12.

[0029] Before use, soil stabilizer is injected into the storage tank 14 of this utility model through the injection hole 19;

[0030] As the utility model is moved to the right by pulling the handle, the pump body 18 drives the curing agent in the storage tank 14 into the spray pipe 12, which is then sprayed onto the soil through the nozzle 13. However, the electric push rod 9 does not work, and the two rotating rods 4 rotate clockwise under the drive of the roller 5 (the clockwise rotation of the rotating rod 4 is...). Figure 2 From the main viewpoint), the left-side rotating rod 4 drives the sector gear 17 to rotate clockwise. When the sector gear 17 protrudes upward, it engages with the second tooth 16 on the upper side of the through hole 15, driving the drive plate 2 to move to the right. The drive plate 2 drives the electric push rod 9 and the loop frame 7 to move to the right. The first tooth 10 on the loop frame 7 engages with the spur gear 11 to rotate clockwise (the clockwise rotation of the spur gear 11 is...). Figure 2 (From a top-down perspective), the column 3 rotates with the circular gear 11, and the column 3 drives the spray pipe 12 to rotate clockwise (the clockwise rotation of the spray pipe 12 is...). Figure 2 (From a top-down perspective), as the left-side rotating rod 4 continues to rotate, after the sector gear 17 disengages from the upper tooth 16 of the through hole 15, the sector gear 17 begins to mesh with the lower tooth 16 of the through hole 15, thereby driving the drive plate 2 to move to the left. The drive plate 2 drives the electric push rod 9 and the loop frame 7 to move to the left, thereby driving the column 3 and the spray pipe 12 to rotate counterclockwise back to the initial position. Therefore, during the process of pulling this utility model to the right, the spray pipe 12 can reciprocate clockwise or counterclockwise rotation. During the rotation of the spray pipe, the range of the curing agent sprayed by the nozzle 13 can be increased.

[0031] This invention requires the curing agent to be sprayed at a fixed position. When the left rotating rod 4 stops rotating, the electric push rod 9 is activated. The electric push rod 9 pushes the loop frame 7 to reciprocate to the right or left. When the loop frame 7 moves to the right, it can drive the upright and the spray pipe 12 to rotate clockwise. When the loop frame 7 moves to the left, it can drive the upright and the spray pipe 12 to rotate counterclockwise. Therefore, this invention can also increase the spraying range of the spray pipe 12 when it is fixed.

[0032] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
