Description

Technical Field

[0001] The utility model relates to the technical field of concrete pushing equipment, in particular to a pushing mechanism for producing fine stone concrete. Background Art

[0002] Fine aggregate concrete generally refers to concrete with a maximum particle size of coarse aggregate not exceeding 15mm. The fine stone particles in fine aggregate concrete are smaller, making the concrete more compact, providing higher compressive strength and durability, and better bonding with various new and old concretes. It is not easy to delaminate after being smoothed and smoothed. Fine aggregate concrete can provide the load-bearing capacity of the structure and is used to build floors, ground, foundations, etc. In the production process of fine aggregate concrete, a single filler generation method or a composite filler generation method can be used. The single filler generation method uses a single filler material such as quartz sand, fine sand, etc., while the composite filler generation method uses a variety of different filler materials for proportioning, such as quartz sand, fine sand, crushed stone, etc.

[0003] The pushing mechanism for producing fine stone concrete usually refers to the mechanical part in a concrete mixing plant, conveyor truck or pumping equipment that is responsible for pushing fine stone concrete from one place to another. After the existing pushing mechanism is used, due to the viscosity and fine particles of fine stone concrete, it is easy to cause concrete residue inside the pushing mechanism, making it difficult to thoroughly clean the inside of the mechanism. Over time, the excessive residue will affect the pushing efficiency of the fine stone concrete. Utility Model Content

[0004] The utility model aims to provide a pushing mechanism for producing fine stone concrete, so as to solve the problem that the pushing mechanism for producing fine stone concrete proposed in the above-mentioned background technology usually refers to the mechanical part in a concrete mixing station, a conveyor vehicle or a pumping equipment, which is responsible for pushing the fine stone concrete from one place to another. After the existing pushing mechanism is used, due to the viscosity and fine particles of the fine stone concrete, it is easy to cause concrete residue inside the pushing mechanism, and it is difficult to thoroughly clean the inside of the mechanism. If it continues for a long time, the residue is too large, which will affect the pushing efficiency of the fine stone concrete.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A pushing mechanism for producing fine stone concrete comprises a pushing mechanism, and a flushing mechanism is arranged on the top of the pushing mechanism;

[0007] The propulsion mechanism includes two combination cylinders, the outer walls of the two combination cylinders are fixedly connected with a feed hopper, the bottom ends of the two combination cylinders are symmetrically fixedly connected with two hinges, a fixed shaft is rotatably sleeved in the hinge, both ends of the fixed shaft are fixedly connected with a support plate, the outer wall of the combination cylinder is symmetrically fixedly connected with two connecting blocks, the outsides of the two connecting blocks are rotatably connected with a lifting seat, a lifting plate is arranged at the bottom of the lifting seat, a driving motor is fixedly connected to the side wall of the support plate, a rotating shaft is fixedly connected to the output end of the driving motor, a spiral pushing plate is fixedly connected to the outer wall of the rotating shaft, and the two combination cylinders are sleeved with the spiral pushing plate.

[0008] Furthermore, two limit grooves are symmetrically provided on the lifting plate, and two T-blocks are symmetrically slidably embedded in the limit grooves about their vertical center planes. The T-blocks are fixedly connected to the bottom end of the lifting seat, and two hydraulic cylinders are symmetrically fixedly connected to the bottom of the lifting plate.

[0009] Furthermore, sealing rubber strips are fixedly arranged on opposite side walls of the two combined cylinders.

[0010] Furthermore, the ends of the two combined tubes are fixedly connected with sleeve shells, the two sleeve shells are sleeved with delivery pipes, and the outer walls of the delivery pipes are fixedly connected with fixing plates.

[0011] Furthermore, the flushing mechanism includes a base table, a support frame is fixedly connected to the top of the base table, a servo motor is fixedly connected to the top of the support frame, a screw rod is fixedly connected to the output end of the servo motor, an internal thread block is screwed and sleeved on the screw rod, a movable cavity plate is fixedly connected to the bottom of the internal thread block, a plurality of high-pressure nozzles connected to the interior of the movable cavity plate are fixedly connected at equal distances to the bottom of the movable cavity plate, an output end of a water pump connected to the interior of the movable cavity plate is fixedly connected to the top of the movable cavity plate, a water tank is fixedly connected to the input end of the water pump, and a water inlet pipe connected to the interior of the water tank is fixedly connected to the top of the water tank.

[0012] Furthermore, both ends of the movable cavity plate are fixedly connected with sliding columns, and the outer portion of the sliding column is slidably sleeved with a limiting sleeve rod fixedly connected with the support frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Pour the fine stone concrete from the feed hopper into the combined cylinder, and then drive the output end of the motor to drive the rotating shaft and the spiral push plate to rotate. The spiral push plate can continuously push the fine stone concrete into the conveying pipe. Under the action of the extrusion force, the concrete can gradually rise from the conveying pipe and be transported to other equipment, thereby improving the pushing effect of the fine stone concrete. When cleaning the inside of the pushing mechanism, the hydraulic cylinder can drive the lifting plate to descend, so that the lifting seats on both sides of the lifting plate move closer to the middle, and the T-block will slide in the upper limit groove of the lifting plate. Since the end of the lifting seat is rotatably connected to the connecting block, the two combined cylinders can be driven to flip around the fixed axis at the same time, so that the propulsion mechanism can be unfolded, and then the flushing mechanism is used to flush the inside, so that the concrete stuck to the inside of the mechanism can be cleaned.

[0015] 2. The output end of the servo motor can drive the screw to rotate, thereby driving the internal thread block and the sliding columns at both ends of the movable cavity plate to slide in the limit sleeve. At the same time, the water pump can pressurize the water in the water tank into the movable cavity plate. In this way, the movable cavity plate can drive multiple high-pressure nozzles to flush the inner wall of the expanded combination cylinder and the surface of the rotating spiral push plate, thereby replacing manual cleaning and improving the cleaning efficiency of the propulsion mechanism.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 5 In an embodiment of the utility model, a pushing mechanism for producing fine stone concrete includes a pushing mechanism 100, and a flushing mechanism 200 is provided on the top of the pushing mechanism 100;

[0024] The propulsion mechanism 100 includes two combination cylinders 101, the outer walls of the two combination cylinders 101 are fixedly connected with a feed hopper 102, the bottom ends of the two combination cylinders 101 are symmetrically fixedly connected with two hinges 104, a fixed shaft 105 is rotatably sleeved in the hinge 104, and both ends of the fixed shaft 105 are fixedly connected with a support plate 106, and the outer wall of the combination cylinder 101 is symmetrically fixedly connected with two connecting blocks 108, and the outsides of the two connecting blocks 108 are rotatably connected with a lifting seat 109, and a lifting plate 111 is provided at the bottom of the lifting seat 109, and the support plate 111 is fixedly connected with the lifting seat 109. A driving motor 114 is fixedly connected to the side wall of 06, a rotating shaft 115 is fixedly connected to the output end of the driving motor 114, a spiral pushing plate 116 is fixedly connected to the outer wall of the rotating shaft 115, and the two combined cylinders 101 are socketed with the spiral pushing plate 116; two limiting grooves 112 are symmetrically provided on the lifting plate 111, and two T-blocks 110 are symmetrically slidably embedded in the limiting grooves 112 about their vertical center planes. The T-block 110 is fixedly connected to the bottom end of the lifting seat 109, and two hydraulic cylinders 113 are symmetrically fixedly connected to the bottom of the lifting plate 111.

[0025] Specifically, by pouring fine stone concrete from the feed hopper 102 into the combined cylinder 101, the output end of the driving motor 114 can drive the rotating shaft 115 and the spiral pushing plate 116 to rotate, and the spiral pushing plate 116 can be used to continuously push the fine stone concrete into the conveying pipe 203. Under the action of the extrusion force, the concrete can gradually rise from the conveying pipe 203 and be transported to other equipment, thereby improving the pushing effect of the fine stone concrete. When the interior of the pushing mechanism 200 is cleaned, the hydraulic cylinder 113 can drive the lifting plate 111 to descend, so that the lifting seats 109 on both sides of the lifting plate 111 move closer to the middle, and at the same time, the T-block 110 will slide in the upper limit groove 112 of the lifting plate 111. Since the end of the lifting seat 109 is rotatably connected to the connecting block 108, the two combined cylinders 101 can be driven to flip around the fixed axis 105 at the same time, so that the propulsion mechanism 100 can be unfolded, and then the flushing mechanism 200 is used to flush the interior thereof, so that the concrete stuck to the interior of the mechanism can be cleaned off.

[0027] In this embodiment, when the two combination tubes 101 are closed, the two sleeve shells 103 can be driven to close together. When the two sleeve shells 103 are closed, they can be squeezed and sleeved with the delivery pipe 203, thereby ensuring that the concrete can be pushed from the end of the combination tube 101 to the delivery pipe 203. By providing a sealing rubber strip 107 on the side wall of the combination tube 101, the sealing performance of the propulsion mechanism 100 when merging can be improved. Embodiment 2

At the same time, the water pump 210 can pressurize the water in the water tank 211 into the movable cavity plate 208, so that the movable cavity plate 208 can drive multiple high-pressure nozzles 209 to flush the inner wall of the unfolded combination cylinder 101 and the surface of the rotating spiral push plate 116, thereby replacing manual cleaning and improving the cleaning efficiency of the propulsion mechanism 100.
