[0002] Concrete products such as sidewalk bricks, curbstones, concrete slabs, driveway bricks, etc. are currently widely used in highway construction. Concrete products replace stone materials and have the characteristics of low cost and resource conservation. At present, many machines for producing concrete products have various shortcomings and cannot meet production needs. Therefore, I designed and invented a concrete slab casting and molding machine to solve some of the problems, but this molding machine is still used separately from the concrete tanker when in use, and the poured curbstones need to be transported to another site for storage, so it occupies a large area. Now in the construction process, the temporary site construction fee accounts for a large part of the construction cost of the project, and the rent is also very expensive, which has caused the cost of the enterprise to increase, thus bringing great trouble to the production enterprise.

DETAILED DESCRIPTION

[0030] The accompanying drawings are specific embodiments of the present invention. Figures 1 to 10 As shown, the vehicle-mounted prefabricated concrete component forming platform can use mains electricity or carry a 30-kilowatt generator on the vehicle to generate electricity. The present invention includes a concrete mixer truck, which is modified from a heavy-duty vehicle: a backward power output shaft 16 is added to the rear axle of the heavy-duty vehicle, and the power output shaft is a spline shaft, and then a clutch 18 is inserted and fastened, and the clutch is then connected to an electric reducer 17. The above connection method is a prior art and will not be repeated here. (If the electric reducer itself has a clutch, there is no need to install the clutch separately) The electric reducer 17 can be installed on the frame 1, and the concrete mixer truck can be driven forward by operating the electric reducer 17. The concrete mixer truck comprises a frame 1, on which a water storage and cleaning tank 2 and a mixing tank 4 are mounted. The water storage and cleaning tank 2 is a horizontally placed cylinder mounted below the mixing tank 4. An upper overflow pipe 201 is mounted on the upper portion of one end of the cylinder. The upper overflow pipe 201 is connected to an upper air inlet pipe 202 via a tee. Both the upper overflow pipe 201 and the upper air inlet pipe 202 are controlled by switches, and the upper air inlet pipe 202 can be connected to an air pump; a lower water inlet pipe 203 is mounted below the upper overflow pipe 201, and a lower water outlet pipe 204 is connected to the lower water inlet pipe 203 via a tee. Both the lower water inlet pipe 203 and the lower water outlet pipe 204 are controlled by switches. The lower water inlet pipe 203 can be connected to a water source, such as tap water, and the lower water outlet pipe 204 is connected to a water gun for flushing the mixing tank 4.

[0031] The use process of the water storage and cleaning tank 2 is as follows: first, turn on the switches on the lower water inlet pipe 203 and the upper overflow pipe 201, connect the lower water inlet pipe 203 to tap water, and fill it with water. When the upper overflow pipe 201 flows water outward, it means that it is full of water. At this time, turn off the switches on the lower water inlet pipe 203 and the upper overflow pipe 201; if it is necessary to rinse the mixing tank 4, connect a water gun to the lower water outlet pipe 204, turn on the switch, and then turn on the switch of the upper air inlet pipe 202, and then you can rinse the mixing tank 4.

[0032] The mixing tank 4 is a rectangular parallelepiped in the front-to-back direction as a whole: the four sides are respectively a front face 401, a left side face 402, a right side face 403 and a sealing plate 404 at the rear end; the top is an open top plate 405, and a circle of surrounding plates 406 are welded upward at the opening of the top plate 405 to prevent concrete from overflowing during the mixing process; the bottom is a bottom plate 407, and the bottom plate 407 is inclined, with the front higher and the back lower. In order to clean the concrete thoroughly, the bottom plate 407 is preferably an arc-shaped plate, and is transitioned by inclined plates 408 at the two bottom corners of the rear end; a concrete outlet 409 is opened at the lower end of the sealing plate 404. In order to make the sealing plate 404 firm, at least two reinforcing rib plates 410 are welded between the bottom plate 407 and the sealing plate 404 in the concrete outlet 409. In addition, a sliding door 411 is installed at the concrete outlet 409, which can be pushed and pulled in the up and down directions. Two guide grooves 412 in the up and down directions are welded at the left and right ends of the concrete outlet 409. The two ends of the sliding door 411 are located in the guide grooves 412. At least two pushing and pulling cylinders 413 are installed on the blocking plate 404 above the concrete outlet 409. The output ends of the pushing and pulling cylinders 413 face downward and are then fixed on the sliding door 411 respectively. The opening and closing of the sliding door 411 is controlled by the pushing and pulling cylinders 413.

[0033] A stirring tooth 414 is installed in the stirring tank 4 in the front and rear directions. The front and rear ends of the stirring shaft of the stirring tooth 414 are respectively fixed on the front end surface 401 and the blocking plate 404 through bearings, and a number of stirring blades are installed on the stirring shaft. In order to stabilize the stirring shaft, a bearing seat 415 can also be sleeved on the stirring shaft, and then a bearing is installed in the bearing seat 415. Two support frames 416 are welded on the bearing seat 415, and the support frame 1 is welded to the bottom plate 407 or two side surfaces at the same time. The stirring shaft is driven to rotate by a stirring motor.

[0034] A hopper 5 is installed at the rear end of the frame 1. The hopper 5 is located below the concrete outlet 409. The hopper 5 is composed of a front vertical plate 501, a rear vertical plate 502 and blocking plates 503 at both ends. The front vertical plate 501 can be upright, but the rear vertical plate 502 is inclined, that is, the hopper 5 has a large upper opening and a small lower opening. The lower end of the rear vertical plate 502 is higher than the lower end of the front vertical plate 501. The upper ends of the front vertical plate 501 and the rear vertical plate 502 are connected together by a connecting plate 504. The distance between the two blocking plates 503 can be adjusted, that is, the positions of the two blocking plates 503 can be adjusted. The adjustment method is: 3, two ear plates 505 with holes are welded, the lengths of the two ear plates 505 are in the left-right direction, but the plane of one is in the horizontal direction, and the plane of the other is in the up-down direction. At the same time, a position adjustment plate 506 with a plurality of holes is welded on the connecting plate 504 and the front vertical plate 501, respectively. The two position adjustment plates 506 are matched with the two ear plates 505, respectively. Each pair of ear plates 505 and the position adjustment plates 506 are fixed together by adjusting bolts 507. By adjusting the position of the adjusting bolts 507 on the position adjustment plates 506, the position of the blocking plate 503 is adjusted, thereby adjusting the size of the hopper 5. The connecting plate 504 and the front vertical plate 501 can be fixed on the frame 1.

[0035] A vibrator 6 is installed on the rear vertical plate 502 to evenly distribute the material in the hopper 5 and evenly flow into the curbstone mold box.

[0036] At the lower end of the hopper 5 is a hopper door 7, which can rotate, but there is no connection between the hopper door 7 and the front vertical plate 501 and the rear vertical plate 502, and its rotation is mainly achieved through the following structure (the structures at both ends of the hopper 5 are the same, so only one end is taken as an example): two connecting rods 8 are hinged on the connecting plate 504, and the two connecting rods 8 are arranged front and back, and the lower ends of the two connecting rods 8 are hinged at the ends of the hopper door 7, respectively, or the front vertical plate 501 and the hopper door 7 can be fixedly connected, and the rear vertical plate 502 and the hopper door 7 can be hinged, and a hopper cylinder 9 can be hinged on the frame 1, and this hopper cylinder 9 can swing up and down around its hinge point, and the output end of the hopper cylinder 9 faces backward and is hinged on the front connecting rod 8, through the hopper The cylinder 9 drives the connecting rod 8 to swing, thereby controlling the opening and closing of the hopper door 7; because the lower end of the front vertical plate 501 is lower than the lower end of the rear vertical plate 502, the lower end of the blocking plate 503 and the hopper door 7 are both inclined, so that the lower ends of the two connecting rods 8 are also not at the same height: the front connecting rod 8 is low, and the rear connecting rod 8 is high; because it is impossible and unnecessary to seal between the hopper door 7 and the rear vertical plate 502, during the vibration of the vibrator 6, some concrete will inevitably splash out and splash onto the operator. Therefore, a baffle plate 10 is installed on the rear vertical plate 502, and the lower end of the baffle plate 10 is lower than the lower end of the rear vertical plate 502. Because the hopper door 7 will hit the baffle plate 10 when it is opened, the baffle plate 10 is preferably made of rubber.

[0037] Two guide cylinders 11 in the up-and-down direction are respectively installed on both sides of the rear end of the frame 1. A guide rod 12 is sleeved in each guide cylinder 11. The lower end of the guide rod 12 is fixed on a lifting platform 14. A lifting cylinder 13 is also fixedly installed on the frame 1 between the two guide cylinders 11. Of course, the guide cylinder 11 and the lifting cylinder 13 can also be said to be installed on the two sides of the mixing tank 4; the output end of the lifting cylinder 13 faces downward, and its output end is fixed to the two ends of the lifting platform 14. The lifting platform 14 includes a rectangular frame 141, and a plurality of rollers 142 are installed in the frame 141. These rollers 142 are in the left-right direction, which is also the length direction of the lifting platform 14. There is a driving shaft 143 and a driven shaft 144 at the front and rear ends of the frame 141 respectively. Gears are installed at both ends of the driving shaft 143 and the driven shaft 144, and then the driving shaft 143 and the driven shaft 144 are connected by a transmission chain 145. The driving shaft 143 is linked to a driving motor 146 and is driven to rotate by the driving motor 146. The driving motor 146 can be installed on the guide rod 12 or fixed on the frame 141; a push rod 147 is connected between the two transmission chains 145.

[0038] The startup of all the above devices is controlled manually, so a control panel 3 is installed on the frame 1, and all control buttons are installed on the control panel 3.

[0039] The use process is as follows (taking the length of the curbstone as 1 meter and the operating interval between the curbstones on site as 30 centimeters as an example): first, drive the present invention under the large concrete tank, add the stirred concrete into the mixing tank 4, then drive it to the construction site, start stirring (it is always in a stirring state during the process of pouring the curbstone), raise the platform to a suitable position, place the curbstone mold box on the platform, adjust the position of the blocking plate 503, operate the two push-pull cylinders 413 to start at the same time, open the sliding door 411, start discharging materials into the hopper 5, and start the vibrator 6 at the same time, and judge how much material needs to be put in the hopper 5 based on experience (a ruler or a height indicator can also be set in the hopper 5 to adjust the capacity of the hopper 5 for different curbstone mold boxes each time) ), after a batch of materials is put out, the sliding door 411 is closed again, the vibrator 6 stops vibrating, the hopper cylinder 9 is started, the hopper door 7 is opened, and the concrete in the hopper 5 falls into the curbstone mold box. After falling, the hopper door 7 is closed, the lifting cylinder 13 is started, and the platform is driven to fall to a suitable position. At this time, the platform should be close to the ground. At the same time, the electric reducer 17 and the pushing motor 146 are started, and the push rod 147 pushes all the curbstone mold boxes away from the platform and falls to the ground. At this time, since the electric reducer 17 drives the entire invention to move forward, the position of the curbstone does not actually change much. The electric reducer 17 drives the present invention forward 1.3 meters, thereby opening a distance of 30 centimeters from the previous curbstone as an operating space, and then repeats the above steps.

[0040] Except for the technical features described in the specification, the other technical features are known technologies to those skilled in the art.
