Description

Technical Field

[0001] This utility model belongs to the field of conveying equipment technology, and specifically relates to a concrete conveying equipment for construction. Background Technology

[0002] In modern construction engineering, concrete, as one of the most commonly used building materials, directly affects project progress and construction quality through its conveying efficiency and quality. As the construction industry develops towards higher-rise and larger-scale structures, the performance requirements for concrete conveying equipment are constantly increasing. In existing concrete conveying equipment, after the concrete is conveyed, some concrete adheres to the inner wall of the conveying box. If not cleaned promptly, this concrete can easily harden, affecting subsequent use, and cleaning is difficult.

[0003] Referring to Chinese patent document CN214885580U, entitled "A Concrete Conveying Device," the device includes a base, hydraulic cylinders, a conveying box, a feed hopper, and a discharge hopper. Two hydraulic cylinders are spaced apart on the base, and the conveying box is mounted on the output end of each cylinder. The hydraulic cylinders and the conveying box are hinged. The feed hopper and discharge hopper are located at opposite ends of the conveying box. In use, by adjusting the height of the two hydraulic cylinders, the discharge hopper of the conveying box can be positioned at different heights, facilitating the delivery of concrete to the pouring location.

[0004] Referring to the above technical solutions, after concrete pouring, some residual concrete adheres to the inner wall of the conveying box and is difficult to discharge. Concrete easily solidifies upon contact with air, causing clumps to form on the inner wall of the conveying box, making it difficult to clean and affecting conveying efficiency in subsequent uses. Therefore, this utility model provides a concrete conveying device for construction, which effectively solves the problem of difficult-to-clean concrete adhering to the inner wall of the conveying box after conveying, enabling automated cleaning and improving conveying efficiency. Utility Model Content

[0005] The technical problem to be solved by this utility model is that concrete adhering to the inner wall of the conveyor box is difficult to discharge, and the residual concrete is easy to solidify, which affects the conveying efficiency and the service life of the equipment.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a concrete conveying device for construction, including a conveying box, an inlet, a discharge outlet, and a drive motor. Concrete enters from the inlet of the conveying box and is subsequently discharged from the discharge outlet to a specific location. A cover plate is installed on the top of the conveying box; the cover plate is designed to be removable for easy maintenance of internal components. A locking ring is installed on the cover plate, and an infusion pipe is installed on the locking ring. The infusion pipe passes through the discharge end of the conveying box, meaning the locking ring can fix the infusion pipe. Water can enter through the infusion pipe, and a pump is installed on the infusion pipe. A spray nozzle located inside the conveying box is also installed on the infusion pipe. The pump delivers cleaning water to the nozzle, which is then aimed at the inner wall of the conveyor box for cleaning. A rotating shaft inside the conveyor box is connected to the output shaft of the drive motor. An auger blade is mounted on the rotating shaft; as the shaft rotates, it drives the auger blade to rotate, conveying concrete towards the discharge port. A linear array of arc-shaped scrapers is arranged on the rotating shaft for cleaning the inner wall of the conveyor box. During cleaning, the drive motor drives the rotating shaft to rotate slowly, which not only allows the arc-shaped scrapers to remove concrete adhering to the inner wall of the conveyor box, but also, driven by the auger blades, prolongs the time the water stays inside the conveyor box, improving cleanliness.

[0007] Optionally, the feed end of the conveyor box is equipped with a drain port, which allows the mixture of water and concrete to flow out under its own weight. The drain port is equipped with a twist cap, which prevents the concrete from falling out of the drain port during conveying.

[0008] Optionally, the conveyor box is equipped with an adjustment assembly for adjusting the height of the discharge port. The adjustment assembly includes a first bracket and a second bracket hinged to the conveyor box. A first set of anchor bolts is installed on the first bracket, and a second set of anchor bolts is installed on the second bracket. The height of the first bracket and the second bracket can be adjusted by controlling the first set of anchor bolts and the second set of anchor bolts, thereby adjusting the height of the discharge port.

[0009] Optionally, the conveyor box is equipped with a sliding assembly for moving equipment. The sliding assembly can help workers easily move equipment. The sliding assembly includes a support rod and a third bracket installed on the conveyor box. Both the support rod and the third bracket are equipped with casters. When the casters are in contact with the ground, workers can easily push the equipment to move and adjust its position and direction.

[0010] Optionally, the third support and the conveyor box are hinged, and a telescopic cylinder is installed between the conveyor box and the third support. Both ends of the telescopic cylinder are hinged, meaning that the telescopic cylinder can tilt the third support at a certain angle while extending and retracting, which facilitates the adjustment of the third support by the staff and enhances the flexibility of the equipment during movement. Simultaneously, when the equipment is erected on the ground, the extension and retraction of the telescopic cylinder can make the casters of the third support contact the ground, serving as a support to enhance the stability of the device.

[0011] Optionally, a vibrator is installed on the conveyor box. The vibrator can improve the conveying efficiency of concrete and reduce the occurrence of blockages through vibration.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, by activating a pump, water is delivered from the infusion pipe to the nozzle. The water flow from the nozzle is aimed at the inner wall of the conveying box and the auger blades. Simultaneously, the drive motor is activated to rotate the shaft, auger blades, and arc-shaped scrapers. As the auger blades rotate, they can transport the water inside the conveying box upwards. The water flows towards the feed end of the conveying box due to its own gravity. The rotation of the auger blades can prolong the time that the cleaning water stays inside the conveying box, improving the cleaning of residual concrete on the inner wall of the conveying box. The spaced arc-shaped scrapers can scrape off the concrete on the inner wall of the conveying box, allowing the water and concrete mixture to flow together to the discharge end. Compared with existing technologies, this concrete conveying equipment can help workers easily clean residual concrete on the inner wall of the conveying box, reducing the labor intensity of workers and improving work efficiency.

[0014] Secondly, by adjusting the component settings, the first set of anchor bolts and the second set of anchor bolts can be rotated to adjust the height of the discharge port according to actual needs, increasing the flexibility and applicability of the equipment.

[0015] Thirdly, the sliding components make it easier to move and adjust the position of the equipment, thus improving construction efficiency.

[0016] Fourth, the combination of the telescopic cylinder and the third support not only enhances the flexibility of the equipment during movement, but also serves as a support to enhance the stability of the device when it is erected, thus improving the safety and stability of the equipment.

The rotating shaft 25 is connected to the output shaft of the drive motor 14. Both ends of the conveyor box 1 are equipped with bases for the rotating shaft 25, which are mounted through the shaft. The auger blades 26 are mounted on the rotating shaft 25, extending from the inlet 11 to the outlet 12. The auger blades 26 do not contact the nozzle 24, and the nozzle 24 is located on one side of the rotating shaft 25. The arc-shaped scraper 27 is arranged in a linear array on the rotating shaft 25. When the rotating shaft 25 rotates, the scraper can scrape away the concrete adhering to the inner wall of the conveyor box 1. The drain outlet 28 is installed at the feed end of the conveyor box 1 and is located below the feed inlet 11. The drain outlet 28 is equipped with a twist cover 29, which makes it convenient for workers to open or close the drain outlet 28. When it is necessary to clean the inside of the conveyor box 1, the twist cover 29 is opened to allow the wastewater and concrete mixture after cleaning to be discharged from the drain outlet 28.

[0027] like Figure 1 As shown, the adjusting assembly 3 includes a first bracket 31, a second bracket 32, a first set of anchor bolts 33, and a second set of anchor bolts 34. The first bracket 31 and the second bracket 32 ​​are H-shaped and spaced apart on the conveyor box 1. The first bracket 31 and the second bracket 32 ​​are hinged to the conveyor box 1. The first set of anchor bolts 33 is installed on the first bracket 31, and the second set of anchor bolts 34 is installed on the second bracket 32. Both the first set of anchor bolts 33 and the second set of anchor bolts 34 are designed to be height-adjustable. By rotating the bolts, the height of the first bracket 31 and the second bracket 32 ​​can be adjusted, thereby achieving the adjustment of the height of the discharge port 12.

[0028] like Figure 1As shown, the sliding assembly 4 includes a support rod 41, a third bracket 42, casters 43, and a telescopic cylinder. The support rod 41 is fixedly installed at the feed end of the conveyor box 1. The third bracket 42 is located between the first bracket 31 and the second bracket 32 ​​and is hinged to the conveyor box 1. The third bracket 42 is A-shaped. Casters 43 are installed at the bottom of both the support rod 41 and the third bracket 42. The support rod 41 has one caster 43 at its bottom, and the third bracket 42 has two casters 43 at its bottom. The casters 43 are equipped with foot brakes.
