Specific embodiments

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As Figure 1 shown, the present utility model provides a waste recycling device for a concrete mixing plant, including a box body 1. Four support legs are fixedly connected to the lower surface of the box body 1 in a rectangular array. A stone discharging port 2 communicating inside and outside is provided on the front surface of the box body 1. A feeding port communicating up and down is provided on the upper surface of the box body 1. A feeding funnel 3 is fixedly connected inside the feeding port. Two motors 4 are fixedly connected mirror-symmetrically in the front and rear of the right side of the box body 1;

[0027] Due to the electrical connection of the motor 4 and the wire power supply, the phenomenon of easy startup is facilitated, so that the crushing structure works and the phenomenon of easy crushing of concrete blocks is facilitated. Due to the setting of the feeding funnel 3, the effect of facilitating the entry of concrete into the box body 1 is achieved.

[0028] As Figure 2As shown in the figure, the output shafts of the two motors 4 both penetrate into the interior of the box body 1 and are movably connected to each other. The left ends of the output shafts of the two motors 4 are fixedly connected with fixed shafts 11. The middle part of the outer surface of the fixed shaft 11 is fixedly connected through a broken cylinder 12. The left side of the outer surface of the fixed shaft 11 is movably connected to the left inner wall of the box body 1. On the left and right sides of the rear inner wall of the box body 1, mounting seats 14 are fixedly connected. A sliding rod 15 is fixedly connected through the opposite surfaces of the left and right mounting seats 14. On the left and right sides of the outer surface of the sliding rod 15, a first spring 16 is sleeved. The outer surface of the sliding rod 15 penetrates and is slidably connected with a trapezoidal screen plate 17. The left and right ends of the first spring 16 are fixedly connected to the opposite surfaces of the trapezoidal screen plate 17 and the mounting seat 14. On the upper left and right sides of the outer surface of the trapezoidal screen plate 17, a first baffle 18 is fixedly connected. On the lower surface of the inner wall of the box body 1, a sand discharging assembly 13 is fixedly connected;

[0029] By starting the two motors 4, the two fixed shafts 11 and the broken cylinder 12 rotate, facilitating the crushing effect. The crushed sand and gravel fall on the trapezoidal screen plate 17 for screening, separating the stones from the sand. The stones are discharged through the stone discharge port 2. Through the arrangement of the sliding rod 15 and the first spring 16, the left and right movement of the trapezoidal screen plate 17 is facilitated, and the first spring 16 is squeezed to have a buffering effect.

[0030] As Figure 3 shown in the figure, a strip-shaped opening 5 communicating inside and outside is formed in the middle of the rear side of the box body 1. A sand discharging port 6 communicating inside and outside is formed in the lower part of the rear side of the box body 1. A connecting block 101 is fixedly connected to the middle of the rear side of the trapezoidal screen plate 17. The outer surface of the connecting block 101 is slidably connected to the inside of the strip-shaped opening 5. Two adjusting plates 102 are arranged on the rear side of the box body 1. A connecting shaft penetrates through the two adjusting plates 102 and is movably connected. A vertical plate 103 penetrates through the outer surface of the connecting shaft and is movably connected. A square block is movably connected to the front side of the right adjusting plate 102. The front side of the square block is fixedly connected to the rear side of the box body 1. A cylinder 104 is fixedly connected to the upper right side of the rear side of the box body 1. The output end of the cylinder 104 is fixedly connected to the middle of the upper surface of the vertical plate 103;

[0031] By starting the cylinder 104, the vertical plate 103 moves up and down. Due to the arrangement of the connecting shaft, the two adjusting plates 102 move, driving the connecting block 101 to move, and then driving the trapezoidal screen plate 17 to move left and right, so as to perform the screening operation to quickly separate the sand and gravel. Through the arrangement of the sand discharging port 6, the sieved sand is discharged conveniently.

[0032] As Figure 4As shown in the figure, square grooves 1011 are provided on the front sides of the upper and lower surfaces of the connecting block 101. Roller shafts 1012 are movably connected to the left and right sides of the front and rear sides of the inner wall of the square groove 1011. The outer surface of the roller shaft 1012 is lapped with the inner wall of the strip-shaped opening 5. A cylindrical rod is movably connected to the rear side of the connecting block 101, and the outer surface of the cylindrical rod penetrates through the left adjusting plate 102 and is fixedly connected;

[0033] Through the arrangement of the square groove 1011 and the roller shaft 1012, it is convenient for the connecting block 101 to roll on the inner wall of the strip-shaped opening 5 when moving left and right, thereby reducing the phenomenon of friction, improving the flexibility of the left and right movement of the connecting block 101, and facilitating the movement.

[0034] As Figure 5 shown, the sand discharging assembly 13 includes an L-shaped plate 131. Spring two 132 is fixedly connected to the left and right sides of the front side in the horizontal direction of the L-shaped plate 131. Positioning grooves 133 are provided on the left and right sides of the rear side in the vertical direction of the L-shaped plate 131. Connecting plates are fixedly connected to the left and right sides of the rear side in the horizontal direction of the L-shaped plate 131. A positioning block is movably connected to the opposite surfaces of the left and right connecting plates. A discharging plate 134 is fixedly connected to the front side of the positioning block. Baffle two 135 is fixedly connected to the left and right sides of the upper surface of the discharging plate 134. The left and right baffle two 135 are in an inclined state and are mirror-image arranged. The discharging plate 134 is in an inclined state. Sliders 136 are fixedly connected to the left and right sides of the front side of the discharging plate 134. The lower surface of the discharging plate 134 is fixedly connected to the upper end of the spring two 132. The outer surface of the slider 136 is slidably connected to the inside of the positioning groove 133;

[0035] When the sieved sand falls on the discharging plate 134, and through the arrangement of the baffle two 135, it is convenient for the sand to be discharged. And when the sand falls on the discharging plate 134, it will drive the discharging plate 134 to move downward, thereby having a certain impact force, facilitating the extrusion of the spring two 132. Under the elastic force of the contraction of the spring two 132, the discharging plate 134 moves up and down, thereby preventing the wet sand from adhering to the discharging plate 134 and having a cleaning effect. At the same time, the slider 136 slides inside the positioning groove 133.

[0036] Next, specifically describe the working principle of the waste recycling equipment of the concrete mixing plant.

[0037] The start of two motors 4 causes the two fixed shafts 11 and the crushing cylinder 12 to rotate, facilitating the crushing effect. At the same time, the start of the cylinder 104 drives the vertical plate 103 to move up and down. Due to the setting of the connecting shaft, the two adjusting plates 102 are movable, driving the connecting block 101 to move, thereby driving the trapezoidal screen plate 17 to move left and right and squeezing the first spring 16. The setting of the sand discharge port 6 facilitates the discharge of the screened sand. When the screened sand falls on the discharge plate 134, the setting of the second baffle 135 facilitates the discharge of the sand. And when the sand falls on the discharge plate 134, it will drive the discharge plate 134 to move downward, generating a certain impact force. Due to the setting of the second spring 132, the discharge plate 134 moves up and down, preventing the wet sand from adhering to the discharge plate 134, and facilitating the recycling after the separation of sand and gravel.

[0038] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
