Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a concrete storage hopper tilting structure based on a concrete placing boom. Background Technology
[0002] The working principle of a concrete placing boom is to add raw materials such as aggregates, water and cement into the mixer inside the machine in a certain proportion, and then mix the raw materials evenly through the rotation of the mixer. The mixed concrete is then transported to the construction site or a concrete mixer truck for use through a conveying device. Specifically, its workflow includes aggregate feeding, cement feeding, water feeding, mixing and stirring, and concrete conveying.
[0003] Currently, when raw materials for concrete mixing are fed through a hopper, it is difficult to fully discharge the raw materials in the hopper when it reaches the top of the mixing tank. Some mixed materials tend to remain in the hopper, and long-term accumulation can easily lead to clumping of the remaining mixed materials, which affects subsequent efficiency.
[0004] To address the aforementioned technical deficiencies, a solution is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a concrete hopper tilting structure based on a concrete placing boom. By setting an auxiliary mechanism, the concrete in the tilting hopper can be scraped, the discharge speed can be increased, and the concrete residue in the tilting hopper can be reduced, thereby saving material costs and improving construction efficiency, thus solving the problems mentioned in the background art.
[0006] The purpose of this utility model can be achieved through the following technical solution: a concrete storage hopper tilting structure based on a concrete placing boom, including a mounting frame one, two symmetrically arranged mounting frames two fixedly connected to one side of the mounting frame one, two symmetrically arranged inclined frames fixedly connected to the side of the mounting frame one near the top, a movable frame slidably connected to the inclined frame, a tilting hopper rotatably connected inside the movable frame, and an auxiliary mechanism provided on the upper surface of the mounting frame two.
[0007] The auxiliary mechanism includes a connecting frame fixedly connected to two mounting brackets. A sliding block is slidably connected inside the connecting frame. A connecting plate is fixedly connected to the upper surface of the sliding block. An electric push rod is fixedly installed on the upper surface of the connecting plate. A scraper is provided at the telescopic end of the electric push rod.
[0008] Preferably, the lower surface of the tipping hopper is rotatably connected to a roller two via a bracket, the inner walls of the two inclined frames are provided with guide grooves adapted to the roller two, each of the two inclined frames is fixedly connected to a guide frame adapted to the roller two, and a mixing tank is horizontally slidably connected directly below the guide frame.
[0009] Preferably, the movable frame is fixedly connected to two mounting plates at one end near the mounting bracket, and a pulley for cable traction is rotatably connected between the two mounting plates.
[0010] Preferably, the lower surface of the movable frame is rotatably connected to a roller via a bracket, and the roller is slidably connected to the inclined surface of the tilting frame.
[0011] Preferably, a screw is rotatably connected to the connecting frame on a fixed axis, and the screw passes through the sliding block and is screwed to the sliding block.
[0012] Preferably, the telescopic end of the electric push rod passes through the connecting plate and is fixedly connected to a telescopic rod, a spring is provided inside the telescopic rod, and the end of the telescopic rod is fixedly connected to the scraper.
[0013] The beneficial effects of this utility model are:
[0014] (1) By setting up an auxiliary mechanism, this utility model can scrape the concrete in the tipping hopper, increase the material discharge speed, and reduce the concrete residue in the tipping hopper, saving material costs and improving construction efficiency. It also ensures the compactness of the structure and the convenience of operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: This example is used to solve the problem that the raw materials in the existing hopper are difficult to fully discharge, and some mixed raw materials are easy to remain in the hopper. Over time, the accumulated mixed raw materials are prone to clumping, which affects the efficiency of subsequent processes.
[0025] Please see Figure 1 - Figure 5 As shown, this embodiment is a concrete hopper tilting structure based on a concrete placing boom, including a mounting frame 1. Two symmetrically arranged mounting frames 2 are fixedly connected to one side of the mounting frame 1. The mounting frame 1 is U-shaped, and the mounting frame 2 is bent. Two symmetrically arranged inclined frames 3 are fixedly connected to the top side of the mounting frame 1. A movable frame 4 is slidably connected to the inclined frame 3. The movable frame 4 slides on the inclined frame 3. The traction rope pulls the movable frame 4 to slide on the inclined frame 3, which can realize the conveying of the tilting hopper 5 on the movable frame 4. The tilting hopper 5 is rotatably connected inside the movable frame 4. When the tilting hopper 5 rotates on the movable frame 4, the concrete in the tilting hopper 5 can be discharged. An auxiliary mechanism is provided on the upper surface of the mounting frame 2.
[0026] The auxiliary mechanism includes a connecting frame 8 fixedly connected to two mounting brackets 2. A sliding block 10 is slidably connected inside the connecting frame 8. A connecting plate 11 is fixedly connected to the upper surface of the sliding block 10. An electric push rod 12 is fixedly installed on the upper surface of the connecting plate 11. A scraper 13 is provided at the telescopic end of the electric push rod 12. When the sliding block 10 slides inside the connecting frame 8, the connecting plate 11 fixedly connected to the sliding block 10 can be moved. The telescopic end of the electric push rod 12 pushes the scraper 13 to move in the vertical direction. As the scraper 13 moves, it can scrape the concrete in the tipping hopper 5, increase the concrete discharge speed, and reduce the amount of concrete residue in the tipping hopper 5.
[0027] The lower surface of the tipping hopper 5 is rotatably connected to roller 15 via a bracket. The inner walls of the two tilting frames 3 are provided with guide grooves that are adapted to roller 15. When the moving frame 4 moves along the surface of the tilting frame 3, roller 15 can slide on the inner walls of the opposite side of the tilting frame 3. Both tilting frames 3 are fixedly connected to guide frames 6 that are adapted to roller 15. The mixing tank 7 is horizontally slidably connected directly below the guide frame 6. As the moving frame 4 continues to move, roller 15 can move into the guide frame 6, thereby causing the tipping hopper 5 to tilt and automatically unload into the mixing tank 7.
[0028] Two mounting plates 16 are fixedly connected to one end of the movable frame 4 near the mounting bracket 1. A pulley 17 for cable traction is rotatably connected between the two mounting plates 16. A traction machine is fixedly installed on the mounting bracket 1. The traction machine is connected to the pulley 17 through the wire of the traction machine. When the traction machine is started, it can pull the movable frame 4 to slide along the inclined surface of the inclined frame 3, preventing the movable frame 4 from automatically sliding off the inclined frame 3 under the action of gravity when it is released.
[0029] The lower surface of the movable frame 4 is rotatably connected to a roller 14 via a bracket. The roller 14 is slidably connected to the inclined surface of the inclined frame 3. By setting the roller 14, the friction between the movable frame 4 and the inclined frame 3 can be reduced, making it easier to pull the movable frame 4 to slide on the inclined frame 3. At the same time, it can also ensure that the movable frame 4 and the tipping hopper 5 can be reset under gravity and transport concrete again.
[0030] A screw 9 is rotatably connected to a fixed axis inside the connecting frame 8. The screw 9 passes through the sliding block 10 and is screwed to the sliding block 10. A motor is fixedly installed on one side of the outer wall of the connecting frame 8. The motor drives the screw 9 to rotate, which allows the sliding block 10 to move inside the connecting frame 8, thereby adjusting the position of the connecting frame 8. This allows the scraper 13 to scrape the concrete in the tipping hopper 5, further accelerating the material discharge and reducing concrete residue in the tipping hopper 5.
[0031] Example 2: This example is used to solve the problem of rigid contact, which can easily lead to damage to the instrument.
[0032] Please see Figure 1 , Figure 5 As shown, in this embodiment, the concrete hopper tilting structure based on the concrete placing boom has an electric push rod 12 whose telescopic end passes through the connecting plate 11 and is fixedly connected to a telescopic rod. A spring is installed inside the telescopic rod, and the end of the telescopic rod is fixedly connected to the scraper 13. By setting the telescopic rod and the spring, the scraper 13 can be elastically connected to the telescopic end of the electric push rod 12, preventing the scraper 13 from rigidly contacting the inner wall of the tilting hopper 5, thereby causing interference and damage to the electric push rod 12 or the scraper 13.
[0033] Combining Example 1 and Example 2
[0034] By setting up an auxiliary mechanism, the concrete in the tipping hopper 5 can be scraped through the combination of connecting frame 8, sliding block 10, connecting plate 11, electric push rod 12 and scraper 13, which increases the discharge speed and reduces the residue of concrete in the tipping hopper, saving material costs and improving construction efficiency. Mounting frame 1 and mounting frame 2 form a stable and easy-to-install overall frame, ensuring the compactness of the structure and the convenience of operation. The sliding frame 4 on the tilting frame 3 allows the tipping hopper 5 to slide along the tilting frame 3, which enables the scraper 13 to be elastically connected to the telescopic end of the electric push rod 12, preventing the scraper 13 from rigidly contacting the inner wall of the tipping hopper 5, thereby causing interference and damage to the electric push rod 12 or the scraper 13.
[0035] like Figure 1 - Figure 5 As shown, the working process and principle of this utility model are as follows:
[0036] Step 1: Start the traction machine. The traction machine pulls the moving frame 4 through the wire, so that the moving frame 4 slides along the inclined surface of the inclined frame 3. Under the action of the inclined frame 3 and the guide frame 6, as the moving frame 4 continues to move, the roller 15 can move into the guide frame 6, so that the tipping hopper 5 is tilted and automatically unloads the material, so that the concrete in the tipping hopper 5 falls into the mixing tank 7.
[0037] Step 2: Start motor 1 on one side of the connecting frame 8. Motor 1 drives screw 9 to rotate, which allows sliding block 10 to move inside the connecting frame 8, thereby adjusting the position of the connecting frame 8. This allows scraper 13 to scrape the concrete in the tipping hopper 5, further speeding up the material feeding and reducing concrete residue in the tipping hopper 5.
