Abstract
Description
Technical Field
[0001] This application relates to the field of road maintenance technology, and in particular to a road maintenance agent spraying device. Background Technology
[0002] Road maintenance agents can fully penetrate into the pores and tiny cracks of road concrete, moisturizing, activating, repairing and restoring aging road surfaces, thereby extending the service life of roads. The road maintenance agent is evenly sprayed onto the road surface using a road maintenance agent spraying device.
[0003] Existing road maintenance agent spraying devices can be divided into front spraying type and side spraying type. In the side spraying type, during operation, the operator pushes the spraying device to move the nozzle along the pre-spraying path, thereby separating the walking path from the spraying area and avoiding the operator stepping on the undried maintenance liquid while pushing the spraying device.
[0004] Regarding the aforementioned technologies, the inventors believe that existing side-spraying spraying devices typically use threaded connections to fix the nozzle connecting plate. Before use, operators need to install it with a torque wrench, and after the spraying operation is completed, it needs to be disassembled. The operation process is cumbersome and there are problems with inconvenience in disassembly and use. Utility Model Content
[0005] The purpose of this application is to provide a road maintenance agent spraying device to improve the problem of inconvenient disassembly and assembly of the nozzle connection plate.
[0006] The road maintenance agent spraying device provided in this application adopts the following technical solution:
[0007] A road maintenance agent spraying device includes a base with several rollers at its bottom and a push rod at one end. The base has a storage tank for storing the road maintenance agent, and the storage tank has an infusion hose. Several nozzles are located at the end of the infusion hose away from the storage tank. A slide rail extending along the width of the base is located at the end of the base away from the push rod. A sliding plate is slidably mounted on the slide rail, and a connecting vertical plate is mounted on the sliding plate. The slide rail has a first extension plate and a second extension plate that abut against the connecting vertical plate. The first extension plate has several insertion rods, and the connecting vertical plate has positioning holes for the insertion rods to pass through. The second extension plate has slots for the insertion rods to be inserted into. The connecting vertical plate also has mounting buckles for installing the nozzles.
[0008] By adopting the above technical solution, when performing the spraying operation, the slide plate in the slide rail is first pulled out, so that the insertion rod passes through the positioning hole and is inserted into the slot for fixation. Then, the nozzle connected to the infusion hose is installed and fixed on the connecting vertical plate. After the spraying is completed, the slide plate is returned to the slide rail and re-fixed, thereby simplifying the disassembly and assembly process of the connecting vertical plate and improving the problem of inconvenient disassembly and assembly of the connecting vertical plate.
[0009] Optionally, the end of the insertion rod away from the positioning hole is provided with an extension handle.
[0010] By adopting the above technical solution, operators can easily pull the plug out of the slot simply by holding the extension handle and pulling it outward, realizing a tool-free quick disassembly and assembly process and effectively improving the problem of inconvenient disassembly and assembly of the connecting vertical plate.
[0011] Optionally, the end of the extension handle away from the slot is provided with an auxiliary end.
[0012] By adopting the above technical solution, the auxiliary end provides more contact area for the operator when pulling out the plug, thereby making it easier for the operator to pull out the plug and improving the problem of inconvenient disassembly and assembly of the connecting vertical plate.
[0013] Optionally, the slot is provided with a resilient collar.
[0014] By adopting the above technical solution, when the insertion rod is inserted into the slot for fixation, the surface of the elastic collar and the surface of the insertion rod are tightly fitted together. The elastic abutment action enhances the tightness of the fit between the two, thereby significantly improving the stability of the insertion rod in fixing the connecting vertical plate.
[0015] Optionally, the slot is provided with a retaining groove for the resilient collar to be secured.
[0016] By adopting the above technical solution, the elastic collar and the retaining groove are designed to be embedded, which can effectively enhance the fixing effect of the elastic collar in the slot and prevent the elastic collar from coming out of the retaining groove when the insertion rod is disassembled, thereby ensuring that the elastic collar can play a continuous and stable fixing role.
[0017] Optionally, the end of the insertion rod near the slot is provided with a plug-in end, which can fit into the elastic collar.
[0018] By adopting the above technical solution, when the plug end on the plug rod passes through the elastic collar and is inserted into the slot, the side wall of the plug end fits against the elastic collar. The friction force generated by the elastic deformation strengthens the plug connection, effectively reducing the situation where the plug rod accidentally comes out of the slot due to non-human factors such as vibration and collision.
[0019] Optionally, the end of the plug-in terminal away from the plug rod is provided with a rounded edge.
[0020] By adopting the above technical solution, the rounded corners make it easier for the plug-in end on the plug rod to pass through the elastic collar. The rounded end abuts against the surface of the elastic collar, which facilitates the insertion of the plug-in end into the elastic collar while effectively reducing the possibility of the plug rod accidentally coming out of the slot due to non-human factors such as vibration and collision.
[0021] Optionally, the positioning holes are provided in a plurality of manner.
[0022] By adopting the above technical solution and setting multiple positioning holes, the connecting vertical plate can select the insertion rod to cooperate with different positioning holes according to the needs of the pre-spraying area, and flexibly adjust the extension length of the connecting vertical plate; at the same time, a corresponding number of spray heads can be installed on the connecting vertical plate to achieve precise adjustment of the spraying area.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. When performing spraying operations, first pull out the slide plate in the slide rail, let the insert rod pass through the positioning hole and insert it into the slot for fixation, and then install and fix the nozzle connected to the infusion hose on the connecting vertical plate; after spraying is completed, return the slide plate to the slide rail and fix it again, thereby simplifying the disassembly and assembly process of the connecting vertical plate and improving the problem of inconvenient disassembly and assembly of the connecting vertical plate.
[0025] 2. Operators can easily pull the plug out of the slot by simply holding the extension handle and pulling it outward, realizing a tool-free quick disassembly and assembly process, effectively improving the problem of inconvenient disassembly and assembly of the connecting vertical plate;
[0026] 3. When the plug end on the plug rod passes through the elastic collar and is inserted into the slot, the side wall of the plug end abuts against the elastic collar. The friction generated by the elastic deformation strengthens the plug connection, effectively reducing the possibility of the plug rod accidentally coming out of the slot due to non-human factors such as vibration and collision.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.
[0032] A road maintenance agent spraying device, as described in the following description Figure 1 The system includes a horizontal base 1, with several rollers 11 rotatably mounted on the bottom of the base 1. In this embodiment, the number of rollers 11 is preferably four. A push rod 12 is fixedly mounted on one end of the upper surface of the base 1 by welding. The base 1 is provided with a storage tank 13 for storing road maintenance agent, and the storage tank 13 is cylindrical.
[0033] Reference Figure 1 The storage tank 13 is threadedly connected to and fixedly provided with an infusion hose 14. The end of the infusion hose 14 away from the storage tank 13 is provided with several nozzles 15. In this embodiment, the number of nozzles 15 is preferably three. The infusion hose 14 and the nozzles 15 are connected by a distributor. Different types of distributors are replaced according to the number of nozzles 15.
[0034] Reference Figure 1 The base 1 is fixedly provided with a horizontal slide rail 2 extending along the width direction of the base 1 by welding at one end away from the push rod 12. The slide rail 2 is slidably provided with a horizontal slide plate 21. The slide plate 21 is fixedly provided with a connecting vertical plate 22 by welding. The connecting vertical plate 22 is a vertical plate.
[0035] Reference Figure 1 The slide rail 2 is fixedly provided with a first extension plate 23 and a second extension plate 24 that are in contact with the connecting vertical plate 22 by welding; the first extension plate 23 and the second extension plate 24 are vertical flat plates, and the first extension plate 23 and the second extension plate 24 clamp the connecting vertical plate 22 to ensure that the connecting vertical plate 22 is fixed on the slide plate 21.
[0036] Reference Figure 1The first extension plate 23 is provided with a plurality of insert rods 3, the connecting vertical plate 22 is provided with positioning holes 5 for inserting the insert rods 3 through, and the second extension plate 24 is provided with slots 4 for inserting and fixing the insert rods 3. In this embodiment, the number of insert rods 3 and slots 4 is preferably two, and the insert rods 3 are in the shape of round rods. When performing the spraying operation, the slide plate 21 in the slide rail 2 is first pulled out, and the insert rods 3 are inserted into the slots 4 after passing through the positioning holes 5. After the spraying is completed, the slide plate 21 is returned to the slide rail 2 and re-fixed, thereby simplifying the disassembly and assembly process of the connecting vertical plate 22 and improving the problem of the inconvenience of disassembling and assembling the connecting vertical plate 22.
[0037] Reference Figure 1 The positioning holes 5 are provided in a plurality of manner. In this embodiment, the number of positioning holes 5 is preferably 8. The connecting vertical plate 22 can be selected to cooperate with different positioning holes 5 according to the requirements of the pre-spraying area, and the extension length of the connecting vertical plate 22 can be flexibly adjusted. At the same time, a corresponding number of spray nozzles 15 are adapted and installed on the connecting vertical plate 22, thereby achieving precise adjustment of the spraying area.
[0038] Reference Figure 1 The connecting vertical plate 22 is fixedly provided with a mounting buckle 25 for mounting the nozzle 15 by welding. The mounting buckle 25 is provided with a U-shaped mounting groove. When installing the nozzle 15, the side wall of the nozzle 15 is fitted with the bottom of the U-shaped mounting groove of the mounting buckle 25, so that the nozzle 15 is installed on the mounting buckle 25. The number of nozzles 15 is selected according to the extension length of the connecting vertical plate 22.
[0039] Reference Figure 1 and Figure 2 The end of the insertion rod 3 away from the positioning hole 5 is fixedly provided with an extension handle 31 by welding. The extension handle 31 is in the shape of a round rod. The operator only needs to hold the extension handle 31 and pull it outward to easily pull the insertion rod 3 out of the slot 4, realizing a tool-free quick disassembly and assembly process, effectively improving the problem of inconvenient disassembly and assembly of the connecting vertical plate 22.
[0040] Reference Figure 1 and Figure 2 An auxiliary end 32 is fixedly provided at the end of the extension handle 31 away from the slot 4 by welding. The auxiliary end 32 is spherical. When the plug rod 3 is pulled out, the auxiliary end 32 provides more contact area for the operator, thereby making it easier for the operator to pull out the plug rod 3 and improving the problem of the connection plate 22 being inconvenient to disassemble and assemble.
[0041] Reference Figure 2 and Figure 3The slot 4 is provided with an elastic collar 41. In this embodiment, the elastic collar 41 is preferably made of rubber. The elastic collar 41 is circular. When the insertion rod 3 is inserted into the slot 4 for fixation, the surface of the elastic collar 41 is in close contact with the surface of the insertion rod 3. The slot 4 is provided with a fixing groove 42 for the elastic collar 41 to be fixed. The elastic collar 41 and the fixing groove 42 adopt an embedded fit design, which can effectively enhance the fixing effect of the elastic collar 41 in the slot 4.
[0042] Reference Figure 3 The insertion rod 3 is fixedly provided with a plug end 43 by welding at one end near the slot 4. The plug end 43 is cylindrical. After the plug end 43 passes through the elastic collar 41, the side wall of the plug end 43 can fit with the elastic collar 41, reducing the possibility of the elastic collar 41 dislodging from the slot 4 due to non-human factors.
[0043] Reference Figure 3 The end of the plug-in end 43 away from the plug rod 3 is provided with a rounded corner 431. The rounded corner 431 facilitates the plug-in end 43 on the plug rod 3 to pass through the elastic collar 41. The rounded corner end abuts against the surface of the elastic collar 41, which facilitates the insertion of the plug-in end 43 into the elastic collar 41, while effectively reducing the possibility of the plug rod 3 accidentally dislodging from the slot 4 due to non-human factors such as vibration and collision.
[0044] The implementation principle of this application embodiment is as follows:
[0045] Before spraying, pull the slide plate 21 outward to move the connecting vertical plate 22 out of the slide rail 2 to the target position. Pass the insert rod 3 through the positioning hole 5 of the connecting vertical plate 22 and insert it into the slot 4 of the second extension plate 24. The elastic collar 41 clamps the insert rod 3 by deformation and fits it with the connecting end, thus fixing the insert rod 3 to the slot 4. After the spraying is completed, pull out the insert rod 3, push the slide plate 21 back into the slide rail 2, and fix it again by the insert rod 3. This simplifies the disassembly and assembly process of the connecting vertical plate 22 and improves the problem of the connecting vertical plate 22 being inconvenient to disassemble and assemble.
