Description

Technical Field

[0001] This invention relates to the field of construction technology, specifically to a concrete pumping device. Background Technology

[0002] A concrete pump, also known as a concrete delivery pump, consists of a pump body and a delivery pipe. It is a machine that uses pressure to continuously transport concrete along a pipeline. It is mainly used in building construction, bridge and tunnel construction. It is mainly divided into gate valve concrete delivery pumps and S-valve concrete delivery pumps. Another type is a pump truck, which is formed by mounting the pump body on a truck chassis and equipping it with a telescopic or flexible placing boom. The concrete delivery pipe should be configured according to the characteristics of the project and construction site and the concrete pouring plan.

[0003] The existing equipment has the following disadvantages: when pouring concrete into the pumping device, it is not convenient to remove large stones from the concrete, which can easily cause equipment failure. In addition, traditional equipment only sets up a filter to filter out large stones when cleaning stones. Later, the conveying equipment needs to be shut down to clean the stones separately, which affects the conveying efficiency of concrete. Furthermore, large stones are generally directly discarded and not used, which will cause some waste.

[0004] Therefore, this application proposes a concrete pumping device to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a concrete pumping device to solve the problems mentioned above, which require shutting down the conveying equipment later to separately clean up the stones, affecting the conveying efficiency of concrete, and large stones are generally directly removed and not used, which causes a certain amount of waste.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete pumping device, comprising a conveying box, a buffer box disposed on the upper part of the conveying box, a support disposed on the lower part of the conveying box, and a conveying pipe disposed at the bottom of the conveying box, and further comprising:

[0007] A filtration unit, located inside the buffer tank, is used to filter large stones from the concrete.

[0008] The processing unit, located at the top of the conveyor box, is used to crush and reuse the filtered large stones.

[0009] The processing unit includes a mounting frame on the upper part of the conveyor box, a support rod on the mounting frame, a connecting frame on the side of the support rod near the buffer box, a storage box with a top opening at the bottom of the connecting frame, and a guide box on the conveyor box. The support rod is connected to the crushing component by a traction rope. The crushing component is adjustable inside the guide box for crushing large stones inside the guide box.

[0010] The storage bin has a bottom plate hinged to its bottom. The bottom plate is connected to the storage bin via a first electric telescopic rod on the side away from the buffer bin. Top plates are provided on both sides of the storage bin. A micro switch is provided at the position of the storage bin corresponding to the top plate. The micro switch is electrically connected to the first electric telescopic rod. A buffer component is provided on the top plate to buffer the storage bin when it is reset.

[0011] The buffer component includes a fixed plate disposed on the buffer box, a buffer rod passing through the fixed plate, and a buffer plate disposed below the buffer rod. An elastic element is disposed between the buffer plate and the fixed plate on the buffer rod.

[0012] The lower part of the support rod is provided with a connecting block for connecting the traction rope. The traction rope passes through the mounting frame, and the mounting frame is provided with a guide wheel at the position corresponding to the traction rope.

[0013] The crushing component includes a guide rod designed on the mounting frame, a slider sleeved on the guide rod, and a crushing hammer set on the slider. The upper part of the crushing hammer is connected to the traction rope. The crushing hammer is adjustablely set inside the guide box. The guide box is provided with a limiting material opening at the position corresponding to the crushing hammer.

[0014] The upper part of the breaker hammer is provided with a positioning handle, and the mounting bracket is provided with a clamping component at the position corresponding to the positioning handle to fix the positioning handle.

[0015] The clamping component includes a fixed frame mounted on the mounting bracket. The bottom of the fixed frame has a snap-fit ​​groove at the position corresponding to the positioning handle. A second electric telescopic rod is provided at the lower part of the fixed frame. A snap-fit ​​plate is provided on the second electric telescopic rod. The snap-fit ​​plate passes through the fixed frame. The fixed frame has a limiting groove at the position corresponding to the snap-fit ​​plate for placing the snap-fit ​​plate.

[0016] The buffer box has an inclined discharge port on the side adjacent to the storage box for discharging materials. The discharge port is provided with a material limiting component for blocking stones on the side adjacent to the storage box. The material limiting component includes a connecting rod on the buffer box, a collar sleeved on the connecting rod, a material limiting plate on the side of the collar adjacent to the support rod, and a connecting plate on the other side of the collar. The lower part of the connecting plate is connected to the top plate by a connecting rope.

[0017] The filtering unit includes a second motor mounted on the buffer box and a transmission gear mounted on the power output end of the second motor. The transmission gear is connected to a transmission shaft via a transmission component. The transmission shaft passes through the buffer box, and an auger is installed at the position of the transmission shaft inside the buffer box.

[0018] The bracket is equipped with a first motor, the power output end of the first motor is equipped with a main gear, the main gear is threadedly connected to a driven gear, the driven gear is sleeved on a rotating shaft, the rotating shaft passes through the conveying box, and a stirring rod is installed at the position of the rotating shaft inside the conveying box.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention involves adding concrete into a buffer tank, where a filtration unit filters out large stones. The concrete is then conveyed to a processing unit for crushing. After crushing, appropriately sized stones fall into a conveying tank, where they are mixed and then transported through a conveying pipe. This design allows for the processing of stones during continuous concrete pumping, eliminating the need for separate stone removal, thus improving concrete pumping efficiency. Furthermore, it enables the crushing and utilization of large stones, reducing resource waste.

[0021] 2. In this invention, after the stones inside the storage bin are discharged, the first electric telescopic rod drives the bottom plate to reset and seal the bottom of the storage bin. The crushing component will move down instantly, and then the storage bin will move up instantly via the traction rope. Since the storage bin and the support rod are rigidly connected, the storage bin will collide with the component during the instantaneous upward movement, causing a certain amount of damage. Therefore, a buffer plate is set above the top plate. During the upward movement of the storage bin, the top plate will squeeze the buffer plate, causing the buffer rod to move up. The buffer plate will squeeze the elastic element, and the elastic element will convert kinetic energy into elastic potential energy, which can play a certain buffering role when the storage bin rises, reducing the possibility of damage to the storage bin.

[0022] 3. The second electric telescopic rod of the present invention is electrically connected to the micro switch. When the micro switch is turned on, the positioning handle is inserted into the inside of the locking groove. The second electric telescopic rod drives the locking plate to move into the inside of the limiting groove, so that the locking plate is inserted into the inside of the positioning handle, and the positioning handle is fixed to the fixing frame, so that the breaker hammer stays at the top for a period of time. Then, when the stones in the storage box are completely discharged into the upper part of the limiting port, the second electric telescopic rod drives the locking plate to reset. The breaker hammer moves down instantly under the action of gravity, and crushes the stones in the limiting port by impact force.

[0023] 4. In this invention, when the storage bin moves to its lowest point, the connecting rope is tightened. The connecting rope then pulls the connecting plate to rotate along the connecting rod, causing the limiting plate to block the stones at the discharge port. This prevents stones from continuing to be added to the storage bin during the discharge process. When the storage bin moves to the opposite point, the limiting plate resets, discharging the stones accumulated at the discharge port into the storage bin. This reduces the risk of stones that have just fallen from the storage bin not being discharged when the storage bin moves upward. If the storage bin moves upward and collides with the buffer plate, the stones may jump out of the storage bin and injure the operators on site. Attached Figure Description

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figure 1-17 The present invention provides a technical solution: a concrete pumping device, comprising a conveying box 1, a buffer box 2 disposed on the upper part of the conveying box 1, a support 6 disposed on the lower part of the conveying box 1, and a conveying pipe 5 disposed on the bottom of the conveying box 1, and further comprising:

[0044] Filter unit 3 is located inside buffer box 2 and is used to filter large stones in concrete.

[0045] Processing unit 4 is located on the upper part of conveyor box 1 and is used to crush and reuse the large stones that are filtered.

[0046] It should be noted that during operation, concrete is added into the buffer tank 2, and large stones in the concrete are filtered out by the filter unit 3 inside the buffer tank 2. Then, it is conveyed to the processing unit 4, where it is crushed. After crushing, stones of suitable size fall into the conveying tank 1, are mixed, and then conveyed through the conveying pipe 5. By setting this up, the stones can be processed during the continuous pumping of concrete, eliminating the need to remove the stones separately, thus improving the pumping efficiency of concrete. Furthermore, large stones can be crushed and utilized, reducing resource waste.

[0047] In one embodiment, the processing unit 4 includes a mounting frame 410 disposed on the upper part of the conveying box 1, a support rod 43 disposed on the mounting frame 410, a connecting frame 42 disposed on the side of the buffer box 2 near the support rod 43, a storage box 41 with a top opening disposed at the bottom of the connecting frame 42, and a guide box 47 disposed on the conveying box 1. The support rod 43 is connected to the crushing component 46 by a traction rope 45. The crushing component 46 is adjustablely disposed inside the guide box 47 for crushing large stones inside the guide box 47. The mounting frame 410 is provided with a central shaft 4101 for connecting the support rod 43, and a limiting ring 4102 for guiding the traction rope 45 through the mounting frame 410.

[0048] With this design, large stones fall into the storage bin 41. When the stones inside the storage bin 41 accumulate to a certain amount, the storage bin 41 drives the support rod 43 to rotate along the central axis 4101. During the rotation, the support rod 43 drives the traction rope 45 to move, and the traction rope 45 drives the crushing component 46 to move upward. When the storage bin 41 reaches the lowest point, the stones inside the storage bin 41 fall into the guide box 47. Then the crushing component 46 moves downward and crushes the large stones inside the guide box 47 under the action of gravity.

[0049] In one embodiment, a bottom plate 401 is hinged to the bottom of the storage box 41. The side of the bottom plate 401 away from the buffer box 2 is connected to the storage box 41 via a first electric telescopic rod 412. Top plates 417 are provided on both sides of the storage box 41. A micro switch 49 is provided at the corresponding position of the top plate 417 of the storage box 41. The micro switch 49 is electrically connected to the first electric telescopic rod 412. A buffer component is provided on the top plate 417 to buffer the storage box 41 when it is reset.

[0050] With this design, after the storage bin 41 falls to its lowest point, the top plate 417 presses the micro switch 49, and the micro switch 49 opens the first electric telescopic rod 412. The first electric telescopic rod 412 drives the bottom plate 401 to flip, the storage bin 41 is opened, and then the stones inside the storage bin 41 fall into the guide box 47.

[0051] In one embodiment, the buffer component includes a fixed plate 413 disposed on the buffer box 2, a buffer rod 414 passing through the fixed plate 413, and a buffer plate 415 disposed below the buffer rod 414. An elastic element 416 is disposed between the buffer plate 414 and the fixed plate 413. The elastic element 416 is made of an elastic component such as a spring or a buffer pad.

[0052] The lower part of the support rod 43 is provided with a connecting block 431 for connecting the traction rope 45. The traction rope 45 passes through the mounting frame 410, and the mounting frame 410 is provided with a guide wheel 432 at the position corresponding to the traction rope 45.

[0053] With this design, after the stones inside the storage bin 41 are discharged, the first electric telescopic rod 412 drives the bottom plate 401 to reset and seal the bottom of the storage bin 41. The crushing component 46 will move down instantly, and then the storage bin 41 will move up instantly via the traction rope 45. Since the storage bin 41 and the support rod 43 are rigidly connected, the storage bin 41 will collide with the component during the instantaneous upward movement, causing a certain amount of damage. Therefore, a buffer plate 415 is set above the top plate 417. During the upward movement of the storage bin 41, the top plate 417 will squeeze the buffer plate 415, causing the buffer rod 414 to move up. The buffer plate 415 will squeeze the elastic element 416, and the elastic element 416 will convert kinetic energy into elastic potential energy, which can play a certain buffering role when the storage bin 41 rises, reducing the possibility of damage to the storage bin 41.

[0054] In one embodiment, the crushing component 46 includes a guide rod 462 designed on the mounting frame 410, a slider 461 sleeved on the guide rod 462, and a crushing hammer 463 disposed on the slider 461. The upper part of the crushing hammer 463 is connected to the traction rope 45. The crushing hammer 463 is adjustablely disposed inside the feed box 47. The feed box 47 is provided with a limiting material outlet 48 at the position corresponding to the crushing hammer 463.

[0055] With this design, the breaker 463 moves downward, causing the slider 461 to slide on the guide rod 462. The guide rod 462 can play a certain guiding role when the breaker 463 moves downward. The stones accumulate above the limiting port 48. The bottom of the limiting port 48 is set at an angle, and the opening size at the lower end of the limiting port 48 is smaller than the size of the qualified stones, which can block the stones. Then the breaker 463 moves downward instantly, and the impact force generated by its own gravity crushes the stones in the limiting port 48. The qualified stones fall from the limiting port 48 into the interior of the conveyor box 1.

[0056] In one embodiment, a positioning handle 464 is provided on the upper part of the breaker hammer 463, and a clamping component 411 for fixing the positioning handle 464 is provided at the corresponding position of the mounting bracket 410.

[0057] With this design, when the breaker 463 moves to its highest point, the positioning handle 464 is engaged in the clamping component 411. Then, when the stones inside the storage box 41 are completely discharged above the limiting port 48, the clamping component 411 releases the positioning handle 464, and then the breaker 463 moves down under the action of gravity.

[0058] In one embodiment, the clamping component 411 includes a fixing frame 4111 disposed on the mounting bracket 410. A snap-fit ​​groove 4112 is provided at the bottom of the fixing frame 4111 at the position corresponding to the positioning handle 464. A second electric telescopic rod 4114 is provided at the lower part of the fixing frame 4111. A snap-fit ​​plate 4115 is provided on the second electric telescopic rod 4114. The snap-fit ​​plate 4115 passes through the fixing frame 4111. A limiting groove 4113 for placing the snap-fit ​​plate 4115 is provided at the position corresponding to the snap-fit ​​plate 4115 on the fixing frame 4111.

[0059] With this design, the second electric telescopic rod 4114 is electrically connected to the micro switch 49. When the micro switch 49 is turned on, the positioning handle 464 is inserted into the slot 4112. The second electric telescopic rod 4114 drives the slot plate 4115 to move into the limiting slot 4113, so that the slot plate 4115 is inserted into the positioning handle 464, fixing the positioning handle 464 to the fixing frame 4111. This causes the breaker hammer 463 to stay at the top for a period of time. Then, when the stones in the storage box 41 are completely discharged into the upper part of the limiting port 48, the second electric telescopic rod 4114 drives the slot plate 4115 to reset. The breaker hammer 463 moves down instantly under the action of gravity, crushing the stones in the limiting port 48 by impact force.

[0060] In one embodiment, the buffer box 2 is provided with an inclined discharge port 36 for discharging materials on the side close to the storage box 41. The discharge port 36 is provided with a material limiting component 44 for blocking stones on the side close to the storage box 41. The material limiting component 44 includes a connecting rod 441 on the buffer box 2, a collar 442 sleeved on the connecting rod 441, a material limiting plate 443 on the side of the collar 442 close to the support rod 43, and a connecting plate 444 on the other side of the collar 442. The lower part of the connecting plate 444 is connected to the top plate 417 by a connecting rope 445.

[0061] With this design, when the storage bin 41 moves down to its lowest point, the connecting rope 445 will be tightened. Then, the connecting rope 445 will pull the connecting plate 444 to rotate along the connecting rod 441, so that the limiting plate 443 will block the stones at the discharge port 36, preventing stones from continuing to be added to the storage bin 41 during the discharge process. When the storage bin 41 moves up to its highest point, the limiting plate 443 will reset and discharge the stones accumulated at the discharge port 36 into the storage bin 41. This reduces the risk of stones that have just fallen from the storage bin 41 not being discharged from the storage bin 41 when it moves up. If the storage bin 41 collides with the buffer plate 415, the stones may jump out from the inside of the storage bin 41 and cause injury to the operators on site.

[0062] In one embodiment, the filter unit 3 includes a second motor 32 disposed on the buffer box 2 and a transmission gear 33 disposed on the power output end of the second motor 32. The transmission gear 33 is connected to the transmission shaft 34 through the transmission component 31. The transmission shaft 34 passes through the buffer box 2, and an auger 35 is disposed at the position of the transmission shaft 34 inside the buffer box 2.

[0063] With this design, the second motor 32 rotates, driving the transmission gear 33 to rotate the transmission component 31, which in turn causes the transmission shaft 34 to rotate. Then, the auger 35 on the transmission shaft 34 can move the large stones inside the buffer box 2 to one side of the discharge port 36, and then discharge them from the discharge port 36 into the storage box 41, which facilitates the automated collection and processing of stones.

[0064] In one embodiment, a first motor 11 is provided on the bracket 6, a main gear 12 is provided at the power output end of the first motor 11, a driven gear 13 is threadedly connected to the main gear 12, the driven gear 13 is sleeved on the rotating shaft 14, the rotating shaft 14 passes through the conveying box 1, and a stirring rod 15 is provided at the position of the rotating shaft 14 inside the conveying box 1.

[0065] With this design, the first motor 11 drives the main gear 12 to rotate, which in turn drives the slave gear 13 to rotate the rotating shaft 14, thereby causing the mixing rod 15 to mix the concrete inside the conveying box 1.
