[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0028] like Figure 1-5As shown, a concrete batching machine with screening function provided by an embodiment of the utility model comprises a frame 1, a large stone batching hopper 11, a medium stone batching hopper 12, a small stone batching hopper 13 and a sand batching hopper 14 are fixedly connected to the upper part of the frame 1 along its length direction, a weighing hopper 4 corresponding to each batching hopper is installed at the lower part of the frame 1, a conveyor 2 is also arranged at the lower part of the frame 1, the conveyor 2 passes under each weighing hopper 4, gates 141 are installed at the discharge port of each batching hopper and the discharge port of the weighing hopper 4, a dredging component 3 is arranged in the sand batching hopper 14, and when the gate 141 on the sand batching hopper 14 is opened, the dredging component 3 pushes the sand to the discharge port of the sand batching hopper 14.
[0029] Specifically, the batching machine also includes a control unit, which is arranged in the control room of the concrete mixing station. Each batching hopper is equipped with a vibration motor. This is the prior art and can be directly applied without further elaboration. When the device is in use, the control unit controls the gates 141 of each batching hopper to open, and weighs large stones, medium stones, small stones and sand of corresponding weight according to the concrete grade, and unloads them onto the conveyor 2 through the gate 141 arranged at the bottom of the weighing hopper 4. During this process, when the gate 141 corresponding to the sand batching hopper 14 is opened, the dredging component 3 pushes the sand in the sand batching hopper 14 downward to assist the sand in falling into the corresponding weighing hopper 4. Optionally, the dredging component 3 includes a plate and a driving member for driving the plate to move up and down. The driving member is an existing linear driving mechanism and can be directly applied without further elaboration. The gates 141 include an arc-shaped gate plate and a driving member for driving the gate plate to rotate. This is the prior art and can be directly applied without further elaboration.
[0030] In this embodiment, by setting a dredging component 3 in the sand batching hopper 14, when the water content of the sand in the sand batching hopper 14 is high, the sand in the sand batching hopper 14 cannot fall into the corresponding weighing hopper 4 through the discharge port. At this time, the dredging component 3 can push the sand out of the discharge port from top to bottom to assist the sand in falling, thereby preventing the sand from being unable to fall and causing the concrete raw material ratio to not meet the standards, thereby affecting the concrete strength and affecting the construction progress.
[0031] Furthermore, the dredging assembly 3 includes a cylinder 31 and a first arc-shaped plate 322, and the cylinder 31 drives the first arc-shaped plate 322 to reciprocate in the vertical direction.
[0032] Specifically, in the present embodiment, the cylinder 31 is used to drive the first curved plate 322 to move back and forth, so as to push the sand in the sand batching hopper 14 downward to assist in the discharge of the sand. It should be noted that the width of the first curved plate 322 is smaller than the width of the sand batching hopper 14, so as to ensure that the first curved plate 322 can be moved to the discharge port position of the sand batching hopper 14 as much as possible, and to prevent the first curved plate 322 from being stuck at the discharge port position.
[0033] Furthermore, the dredging component 3 also includes a cross bar 321, which is arranged along the length direction of the discharge port of the sand batching hopper 14. Adjustment rods 32 are fixedly connected to both ends of the cross bar 321. Two groups of cylinders 31 are provided, and the cylinders 31 are fixedly connected to the upper part of the frame 1. The output end of the cylinder 31 is connected to the upper end of the corresponding adjustment rod 32, and the first arc plate 322 is symmetrically fixed to the outer wall of the cross bar 321 at equal intervals.
[0034] Specifically, by providing a cross bar 321 for installing multiple groups of first arc plates 322, the use of driving parts can be reduced, and the first arc plates 322 at various positions of the discharge port of the sand batching hopper 14 can push sand at the same time.
[0035] Furthermore, the first arc-shaped plate 322 is symmetrically arranged about the central axis of the crossbar 321 , and the end of the first arc-shaped plate 322 is bent downward.
[0036] Specifically, by bending the end of the first arc plate 322 downward, when the cylinder 31 pulls the adjusting rod 32 to move upward, the adjusting rod 32 drives the cross bar 321 to move upward through the cross bar 321. Since the concave surface of the first arc plate 322 is downward, the resistance of each first arc plate 322 can be reduced, thereby reducing the driving resistance of the cylinder 31 and protecting the cylinder 31.
[0037] Furthermore, a movable rod 33 is provided between any two first arc-shaped plates 322 arranged along the length direction of the cross bar 321 , the movable rod 33 is rotatably connected to the cross bar 321 , and a second arc-shaped plate 332 is fixedly connected to one side of the movable rod 33 facing the middle of the sand batching hopper 14 .
[0038] Specifically, by providing a movable rod 33 and fixing the second curved plate 332 on the movable rod 33, when the cross bar 321 is driven to move up and down, it can also drive the movable rod 33 to move up and down, so that the second curved plate 332 on the movable rod 33 can also push the sand at the inner wall of the sand batching hopper 14 downward, so that the sand in the lower and middle parts of the sand batching hopper 14 can be gradually transported to the discharge port, and since the movable rod 33 is rotatably connected to the cross bar 321, when moving up and down, the movable rod 33 is affected by the force of the sand, and its angle relative to the cross bar 321 will change to a certain extent. With this arrangement, when the cross bar 321 is driven to move back and forth up and down to transport sand, the second curved plate 332 on the movable rod 33 will not always move back and forth along the same trajectory, thereby expanding the pushing effect of the second curved plate 332 on the sand at the inner wall of the sand batching hopper 14.
[0039] Furthermore, the end of the second arc plate 332 is bent downward.
[0040] Specifically, the second arc plate 332 is bent downward to reduce the resistance encountered by the second arc plate 332 when it reciprocates, thereby reducing the load of the cylinder 31 .
[0041] Furthermore, a circular ring 331 is fixedly connected to the end of the movable rod 33 , and the circular ring 331 is sleeved on the cross bar 321 .
[0042] Specifically, the circular ring 331 is used to realize the rotation connection between the movable rod 33 and the cross rod 321 , which has a simple structure and is not easy to get stuck outside the cross rod 321 , thereby effectively preventing the movable rod 33 from being stuck and unable to rotate.
[0043] Furthermore, the inner diameter of the circular ring 331 is greater than the diameter of the cross bar 321 .
[0044] Specifically, since the inner diameter of the ring 331 is larger than the diameter of the cross bar 321, such a configuration further prevents the movable rod 33 from being stuck and unable to rotate, and when the cross bar 321 is driven to drive the movable rod 33 to move back and forth, the floating range of the movable rod 33 is expanded, and the pushing effect of the second arc plate 332 on the sand on the inner wall of the sand batching hopper 14 is further enhanced.
[0045] Furthermore, the lower end of each adjusting rod 32 and the upper end of each movable rod 33 are pointed.
[0046] Specifically, the resistance encountered by the adjusting rod 32 and the movable rod 33 during the reciprocating movement is further reduced, thereby protecting the cylinder 31 .
[0047] Furthermore, screens are provided at the openings of the upper parts of the large stone batching hopper 11, the medium stone batching hopper 12 and the small stone batching hopper 13, and the meshes of the screens on the large stone batching hopper 11, the medium stone batching hopper 12 and the small stone batching hopper 13 gradually become smaller.
[0048] Specifically, the screens provided in each batching hopper are adjusted according to the stones contained in each batching hopper, and the mesh openings are slightly larger than the diameter of the stones contained in the corresponding batching hopper, so as to facilitate filtering of larger stones and prevent large stones from entering the concrete mixing pot, affecting the strength of the concrete and causing blockage of the pump trucks in the on-site construction.
[0049] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
