[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0032] This application discloses an artificial sand-spreading device. (Refer to...) Figures 1 to 5 The manual sand spreading device includes a sand spreading support 1, an outwardly expanding protrusion 2, a scale 3, a movable bracket 4, a sand spreading support plate 5, a tray funnel 6, a sand spreading assembly 7, and a manual adjustment assembly 8. The outwardly expanding protrusion 2 is fixedly connected to the bottom outer side of the sand spreading support 1, the scale 3 is snapped into the inner side of the outwardly expanding protrusion 2, the movable bracket 4 is slidably connected to one side of the sand spreading support 1, the sand spreading support plate 5 is slidably connected to the top of the movable bracket 4, the tray funnel 6 is fixedly connected to the top of the sand spreading support plate 5, the sand spreading assembly 7 is installed inside the sand spreading support 1, and the manual adjustment assembly 8 is installed on the outer side of the sand spreading support 1.
[0033] The outwardly expanding convex strip 2, together with the scale 3, is used to detect the width of the sand spreading. The movable bracket 4, together with the sand spreading component 7, is used to slide and support the sand spreading support plate 5 and adjust the sand spreading path of the sand spreading support plate 5. The tray funnel 6 is used to place standard sand particles. The manual adjustment component 8 is used to manually adjust the sand scraping thickness and sand scraping area.
[0034] The manual adjustment assembly 8 includes a screw groove frame 81, a handle screw 82, a cross slider coupling 83, a sand scraper 84, and a sand leakage area adjustment part 9. The screw groove frame 81 is fixedly connected to one side of the sand spreading support plate 5. The handle screw 82 is threaded onto the inner side of the screw groove frame 81. The cross slider coupling 83 is installed on the inner side of the connection between the handle screw 82 and the sand scraper 84. The sand leakage area adjustment part 9 is installed on the outer side of the sand spreading support 1.
[0035] The sand leakage area adjustment part 9 includes a grooved fixing ring 91, a pushing ring 92 and an anti-splash plate 93. The grooved fixing ring 91 is fixedly connected to the surface of the sand spreader support 1, the pushing ring 92 is slidably engaged with the outside of the grooved fixing ring 91, and the anti-splash plate 93 is fixedly connected to the outside of the pushing ring 92.
[0036] The sand-laying assembly 7 includes a stepper motor 71, a threaded rod 72, and a linear shaft 73. The stepper motor 71 is installed inside the sand-laying support 1, the threaded rod 72 is installed outside the output end of the stepper motor 71, and the linear shaft 73 passes through the interior of the movable bracket 4 and is fixedly connected to the inner wall of the sand-laying support 1.
[0037] The inner side of the push ring 92 is also fixedly connected to a frosted insert 10 that matches the groove size of the grooved fixing ring 91.
[0038] A displacement sensor 11 for detecting the movement distance of the anti-splash plate 93 is also installed in the middle of the sand-laying support plate 5.
[0039] An electric telescopic rod 12 is also installed on one side of the top of the movable support 4. The outer side of the output end of the electric telescopic rod 12 is fixedly connected to the surface of the sand-laying support plate 5.
[0040] The usage process of the manual sand-spreading device in this embodiment is roughly as follows:
[0041] Standard sand particles are loaded into the tray funnel 6, and the sand-spreading width is determined by the engagement of the outwardly expanding ridge 2 and the scale 3. Rotating the handle screw 82 drives the scraper blade 84 to move downward, and the deflection is compensated by the cross-slider coupling 83 to adjust the gap between the bottom surface of the scraper blade 84 and the road surface. When adjusting the sand leakage area, the push ring 92 of the sand leakage area adjustment part 9 is pushed, which drives the abrasive insert 10 to slide in the groove of the grooved fixing ring 91 to adjust the sand leakage area. The anti-splash plate 93 moves synchronously with the push ring 92 to isolate non-working areas and reduce sand scattering. The displacement sensor 11 monitors the displacement of the anti-splash plate 93 in real time and sends the sand leakage adjustment range back to the control terminal. During the sand-laying process, the stepper motor 71 is started, driving the threaded rod 72 to rotate, which in turn drives the movable bracket 4 to move laterally at a constant speed along the linear axis 73. The electric telescopic rod 12 adjusts the output of the inner rod to the surface distance of the anti-splash plate 93, thereby repeatedly pushing the sand-laying support plate 5 to move on the sand-laying road surface under electric drive. The sand particles fall onto the road surface through the tray funnel 6 and are scraped flat by the sand scraper 84 to form a uniform single layer. Excess sand particles overflow along both sides of the scraper. After the sand-laying reaches the end point, the stepper motor 71 automatically stops, and the handle screw 82 is manually reversed to raise the sand scraper 84. The area of the blank area not covered by sand particles is measured, and the texture depth, roughness, or anti-skid performance of the road surface is calculated based on the sand volume.
[0042] The beneficial technical effects of the manual sand-spreading device in this application are roughly as follows:
[0043] This device adjusts the lateral position of the sand-spreading support plate 5 by sliding it, and uses a scale 3 to read the sand-spreading width in real time, thus adapting to different road surfaces. The height of the scraper plate 84 is finely adjusted via a thread to control the sand layer thickness, ensuring uniformity of the single-layer sand particles. The cross-slider coupling 83 compensates for the eccentric force during scraper movement, preventing jamming. Furthermore, the opening and closing degree of the sand outlet is changed by sliding the push ring 92, controlling the sand flow rate and coverage area. The anti-splash plate 93 reduces sand scattering during sand spreading, improving the cleanliness of the operating environment. The stepper motor 71 drives the threaded rod 72, which, in conjunction with the linear shaft 73, drives the sand-spreading support plate 5 to move at a uniform speed along the linear shaft 73, ensuring sand-spreading accuracy.
[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
