DETAILED DESCRIPTION

[0031] As Figure 1 and Figure 2As shown, a sand blasting machine sand changing distribution trolley, including a movable frame 1, a filter module 2 horizontally slidingly installed on the top of the movable frame 1, a constant volume module 3 longitudinally slidingly installed on the left end of the top of the movable frame 1, and a sand hourglass module 4 installed on the right end of the middle of the movable frame 1, the sand hourglass module 4 is longitudinally arranged side by side with the constant volume module 3, the left end of the filter module 2 is provided with a scraper 5, when the filter module 2 horizontally slides to the leftmost end of the movable frame 1, the filter module 2 is located directly above the constant volume module 3, when the filter module 2 horizontally slides to the rightmost end of the movable frame 1, the scraper 5 pushes the excess sand in the constant volume module 3 into the sand hourglass module 4 for collection. The filter module 2 adds the qualified sand to the constant volume module 3, and the scraper 5 pushes the excess sand in the constant volume module 3 into the sand hourglass module 4, so that the sand in the constant volume module 3 is quantified, and finally the sand in the constant volume module 3 is added to the sand blasting machine 16. Compared with the traditional sand changing, it is more rapid, convenient and accurate. In the unused state, the filter module 2 is located at the rightmost end of the top of the movable frame 1, and the constant volume module 3 is accommodated in the leftmost end of the top of the movable frame 1, so as to avoid the interference of the constant volume module 3 in the process of the left end of the movable frame 1 extending into the sand blasting machine 16. Specifically, the bottom corners of the movable frame 1 are respectively provided with rollers 24, so that the distribution trolley can change sand for sand blasting machines 16 at different positions, and has strong applicability.

[0032] As shown in Figure 2 and Figure 6 The filter module 2 includes a filter box 2a, a horizontal slide rail group 2b and a screen, the top of the filter box 2a is provided with an inlet 6, the bottom is provided with an outlet 7, the two sides of the top of the filter box 2a are slidingly connected with the movable frame 1 through the horizontal slide rail group 2b, the horizontal slide rail group 2b is installed on the middle of the top end of the movable frame 1, the screen is installed in the filter box 2a to screen the sand, and the scraper 5 is installed on the left end of the filter box 2a. When the filter box 2a is pushed to the leftmost end of the movable frame 1 through the horizontal slide rail group 2b, the filter box 2a is located directly above the constant volume module 3. Specifically, the filter box 2a is funnel-shaped; the horizontal slide rail group 2b includes a slide rail and a sliding block, the slide rail is installed on the two sides of the middle of the top end of the movable frame 1, and the sliding block is installed on the two sides of the filter box 2a, the slide rail and the sliding block are slidingly matched, which is a prior art and will not be described in detail here; in order to limit the moving stroke of the filter box 2a and avoid collision between the filter box 2a and the movable frame 1 during horizontal movement of the filter box 2a, the two ends of the slide rail are respectively provided with a stop block 25 for limiting the moving stroke of the filter box 2a; the scraper 5 is installed on the left end of the filter box 2a through a hinge 26, and the scraper 5 is inclinedly arranged; in order to facilitate pushing the filter box 2a, a handle 27 is arranged on the right end of the filter box 2a.

[0033] As shown in Figure 2 and Figure 7As shown, the constant-volume module 3 includes a constant-volume box 3a, a vertical guide rail set 3b, a material guiding plate 3c, and a driving set 3d. The constant-volume box 3a is provided with a sand inlet 8 at the top and a sand outlet 9 at the bottom. The top surface of the sand inlet 8 is substantially flush with the bottom surface of the scraper 5. The constant-volume box 3a is slidably connected to the movable frame 1 through the vertical guide rail set 3b installed at the left end of the top of the movable frame 1. The material guiding plate 3c is installed in the constant-volume box 3a to guide the sand material. The driving set 3d is distributed on the top of the movable frame 1 to drive the constant-volume box 3a to move up and down. In the initial state, the constant-volume box 3a is accommodated at the leftmost end of the top of the movable frame 1, and the filter box 2a is located at the rightmost end of the top of the movable frame 1. The driving set 3d can drive the constant-volume box 3a to move down along the vertical guide rail set 3b until the constant-volume box 3a stops at a suitable position. Specifically, the constant-volume box 3a is shaped with a wide middle and gradually narrowing ends, thereby ensuring sufficient filling of the sand material in the constant-volume box 3a. The vertical guide rail set 3b includes guide rails and guide blocks. The guide rails are installed on both sides of the left end of the top of the movable frame 1, and the guide blocks are installed on both sides of the constant-volume box 3a. The guide rails and the guide blocks are in sliding fit. This is a prior art and will not be described in detail. Similarly, to limit the movement stroke of the constant-volume box 3a, the guide rails are also provided with stop blocks 25 at both ends. The cross section of the material guiding plate 3c is in inverted Y shape, which is designed to avoid the situation that the sand material is accumulated in the middle of the constant-volume box 3a and not fully filled around. In order to facilitate observation of whether there are obvious foreign matters in the constant-volume box 3a and whether the sand material particles have large differences, the sidewall of the constant-volume box 3a is provided with an observation window 10. The left end and both sides of the sand inlet 8 at the top of the constant-volume box 3a are provided with sand blocking plates 28, and the right end is provided with a discharging plate 29. The scraper 5 pushes the excess sand material of the constant-volume box 3a and rolls it to the sand hourglass module 4 through the discharging plate 29. In order to facilitate observation, a constant-quantity line can be provided on the sand blocking plate 28, which is slightly higher than the top surface of the sand inlet 8.

[0034] As Figure 3As shown, the driving group 3d includes a hand wheel 3d1, a rotating shaft 3d2, a steel wire rope 3d3, a limiting piece 3d4, a driving wheel 3d5 and a directional wheel 3d6. The rotating shaft 3d2 is rotatably installed at the top right end of the movable frame 1, and the two ends of the rotating shaft 3d2 extend out of the movable frame 1 and are connected with the hand wheel 3d1 and the limiting piece 3d4 respectively. The driving wheel 3d5 is installed at the two ends of the rotating shaft 3d2 and located in the movable frame 1. The directional wheel 3d6 is installed at the top left end of the movable frame 1 and corresponds to the driving wheel 3d5. The right end of the steel wire rope 3d3 is wound around the driving wheel 3d5, and the left end passes through the directional wheel 3d6 and is connected with the side wall of the constant volume tank 3a. When the constant volume tank 3a needs to move downward, the hand wheel 3d1 is rotated, the rotation of the hand wheel 3d1 drives the rotating shaft 3d2 and in turn synchronously drives the driving wheel 3d5 to rotate, and the rotation of the driving wheel 3d5 loosens the steel wire rope 3d3. Due to the loosening of the steel wire rope 3d3, the constant volume tank 3a falls along the vertical guide rail group 3b under the action of its own gravity until the constant volume tank 3a falls to the appropriate position. At this time, the limiting piece 3d4 locks the rotating shaft 3d2 from rotating any more, and the constant volume tank 3a no longer falls.

[0035] As shown in Figure 4 The limiting piece 3d4 includes a ratchet wheel 3d41, a pawl 3d42, a flange 3d43 and a torsional spring 3d44. The ratchet wheel 3d41 is sleeved on the end of the rotating shaft 3d2. The flange 3d43 is installed on the movable frame 1. The pawl 3d42 is rotatably connected with the flange 3d43 through an axle shoulder screw 3d45. The torsional spring 3d44 is sleeved on the axle shoulder screw 3d45 to realize the automatic reset of the pawl 3d42. The pawl 3d42 is engaged with the ratchet wheel 3d41. When the constant volume tank 3a needs to move downward, the pawl 3d42 is rotated to separate from the ratchet wheel 3d41, then the hand wheel 3d1 is rotated until the constant volume tank 3a moves to the appropriate position, and finally the pawl 3d42 is released. Under the action of the torsional spring 3d44, the pawl 3d42 is automatically reset and engaged with the ratchet wheel 3d41, thereby locking the rotating shaft 3d2 and preventing the constant volume tank 3a from freely falling. In order to be beautiful and safe, the limiting piece 3d4 is arranged in the cover shell 30, and the cover shell 30 is installed on the movable frame 1.

[0036] As shown in Figure 2 and Figure 9As shown, the sand hourglass module 4 includes a sand hourglass box 4a, a sand bag 4b and an electronic scale 4c.

The sand discharging opening 21 is provided with a valve 22 and extends into the sand bag 4b. The sand bag 4b is placed on the electronic scale 4c which is installed at the middle of the movable frame 1. In order to ensure that the sand entering the sand blasting machine 16 has a fixed mass, the scraper 5 pushes the excess sand in the constant volume box 3a into the sand hourglass box 4a. The sand hourglass box 4a collects the excess sand in the constant volume box 3a. After the sand replacement is completed, the valve 22 is opened, and the excess sand collected in the sand hourglass box 4a falls into the sand bag 4b under the action of gravity. When the sand in the sand hourglass box 4a is emptied, the weight of the excess sand is directly measured for subsequent processing. Specifically, the valve 22 is a ball valve.

One end of the baffle 11 is hingedly connected to the fixed turning plate 12, and the other end is hooked by the opening hook plate 13. When it is necessary to open the sand outlet 9, the opening hook plate 13 is pulled to rotate counterclockwise around its hinged portion, the opening hook plate 13 is separated from the baffle 11, and the baffle 11 rotates clockwise around its hinged portion under the action of its own gravity, and the sand outlet 9 is opened. When it is necessary to close the sand outlet 9, the baffle 11 is pulled to rotate counterclockwise around its hinged portion until the baffle 11 contacts the sand outlet 9, and then the opening hook plate 13 is released. The opening hook plate 13 rotates clockwise around its hinged portion under the action of its own gravity until the opening hook plate 13 hooks the baffle 11, and the sand outlet 9 is closed. Specifically, the opening hook plate 13 is in the shape of L.
