Description

Technical Field

[0001] This utility model relates to the technical field of pump truck receiving devices, specifically an anti-clogging pump truck receiving device. Background Technology

[0002] The concrete pump truck receiving device is a crucial component of a concrete pump truck, used to receive concrete material. It plays a vital role in the concrete transportation process. A concrete pump truck is a machine that uses pressure to continuously transport concrete along pipelines. Concrete pump trucks generally do not carry concrete material themselves; instead, the concrete material is directly fed into the receiving device.

[0003] Currently, the material receiving device on the pump truck still has some problems in actual use. For example, because concrete contains stones of different sizes, when the concrete material enters the pump truck's material receiving device, it will be filtered by the filter structure on the material receiving device to prevent larger stones from entering the material receiving device and affecting the subsequent material feeding operation of the pump truck. However, larger stones will be temporarily stored on the filter structure. As the feeding operation continues, some large stones are easy to accumulate on the filter structure, which will block the subsequent feeding. Therefore, we have proposed an anti-clogging pump truck material receiving device to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-clogging pump truck receiving device to solve the problem mentioned in the background art that the current receiving devices on pump trucks are inconvenient to clean the large-volume stones filtered out, which can clog subsequent feed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging pump truck receiving device, comprising a main body, a filter screen fixed inside the main body, stone removal rollers on both sides of the filter screen, bearings at both ends of the stone removal rollers connected to the main body, the filter screen inclined towards the stone removal rollers inside the main body, stone receiving boxes fixed on both sides of the main body, a baffle plate at the connection between the stone receiving boxes and the main body, a motor mounted outside a protective cover, the protective cover mounted outside the main body, a drive shaft, a transmission shaft, and a driven shaft inside the protective cover, the drive shaft fixed to the output end of the motor, the transmission shaft mounted outside the main body via bearings, the driven shaft fixed to the outer end of the stone removal rollers, a receiving base at the bottom of the main body, a spiral blade on the upper side of the receiving base, the spiral blade fixed to the drive shaft at the output end of the motor, and a discharge port at the bottom of the main body, the discharge port being opposite to the spiral blade.

[0006] Preferably, the filter grid is provided with a guide plate on its upper side, and the guide plate is fixed inside the upper end of the main body.

[0007] Preferably, the guide plate is formed in a funnel shape within the main body, and the guide plate never comes into contact with the filter grid and the stone removal roller.

[0008] Preferably, the desander roller is provided with actuating teeth, the actuating teeth are conical in shape, the actuating teeth are staggered with the filter grid, and the spacing between the actuating teeth is equal to the width of the filter grid.

[0009] Preferably, the baffle plate is provided with a groove, and the outer dimensions of the groove are adapted to the actuating teeth on the stone removal roller.

[0010] Preferably, the drive shaft and the transmission shaft are connected by gear transmission, and both the drive shaft and the transmission shaft are connected to the driven shaft by chains and sprockets to form a transmission structure.

[0011] Preferably, the receiving bottom has an arc-shaped surface, and the spiral blade is located at the lowest point on the upper side of the receiving bottom.

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

[0013] (1) The anti-clogging pump truck receiving device is equipped with stone removal rollers on both sides of the filter screen. The filter screen can filter the concrete material, and the large stones filtered out will remain on the filter screen. By tilting the filter screen, the large stones will move to both sides of the filter screen.

[0024] 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.

[0025] Please see Figure 1-8 This utility model provides a technical solution: an anti-clogging pump truck receiving device, including a main body 1, a filter screen 3 fixed inside the main body 1, stone removal rollers 4 on both sides of the filter screen 3, a guide plate 2 on the upper side of the filter screen 3, the guide plate 2 fixed inside the upper end of the main body 1, the guide plate 2 forming a funnel shape inside the main body 1, ensuring that the incoming concrete material can accurately fall on the filter screen 3, thereby ensuring the normal operation of the feeding work, and the guide plate 2 never contacts the filter screen 3 and the stone removal rollers 4, ensuring the normal working state of the stone removal rollers 4.

[0026] The stone removal roller 4 has bearings at both ends connected to the main body 1. The filter screen 3 is inclined towards the stone removal roller 4 inside the main body 1. Stone collection boxes 6 are fixed on both sides of the main body 1. A baffle 5 is provided at the connection between the stone collection box 6 and the main body 1.

[0027] Furthermore, the stone removal roller 4 is equipped with actuating teeth 41. The actuating teeth 41 are conical in shape, which can make the front end of the actuating teeth 41 occupy the minimum space between the filter grids 3, so as to avoid the actuating teeth 41 affecting the normal feeding operation of the filter grids 3. The actuating teeth 41 and the filter grids 3 are staggered, and the distance between the actuating teeth 41 is equal to the width of the filter grids 3. During the rotation of the stone removal roller 4, the stones of the filter grids 3 can be stably actuated into the stone receiving box 6.

[0028] Furthermore, the baffle plate 5 is provided with a groove, and the outer dimensions of the groove are adapted to the actuating teeth 41 on the stone removal roller 4, so that the concrete material and stones adhering to the stone removal roller 4 can be scraped off by the baffle plate 5, ensuring that the subsequent rotation work can proceed normally.

[0029] The bottom of the main body 1 is provided with a receiving base 13, and a spiral blade 12 is provided on the upper side of the receiving base 13. The spiral blade 12 is fixed on the drive shaft 9 on the output end of the motor 8. A discharge port 14 is provided below the main body 1, and the position of the discharge port 14 is opposite to the spiral blade 12.

[0030] Furthermore, the receiving bottom 13 has an arc-shaped shape, and the spiral blade 12 is located at the lowest point on the upper side of the receiving bottom 13, which facilitates material discharge and improves the conveying efficiency of concrete materials.

[0031] The motor 8 is installed on the outside of the protective cover 7, which is installed on the outside of the main body 1. The protective cover 7 is equipped with a drive shaft 9, a transmission shaft 10, and a driven shaft 11. The drive shaft 9 is fixed on the output end of the motor 8, the transmission shaft 10 is installed on the outside of the main body 1 through bearings, and the driven shaft 11 is fixed on the outer end of the stone roller 4.

[0032] Furthermore, the drive shaft 9 and the transmission shaft 10 are connected by gear transmission, and the drive shaft 9 and the transmission shaft 10 are connected to the driven shaft 11 by chains and sprockets to form a transmission structure, ensuring that the motor 8 can drive the destone roller 4 to rotate normally.

[0033] Working principle: When using the anti-clogging pump truck receiving device, the prepared concrete material is first poured into the main body 1. After entering the main body 1 through the guide plate 2, the concrete material can be stably placed in the middle position of the filter grid 3. This ensures that the filter grid 3 can perform normal filtration of the concrete material and avoids the concrete material from contacting the stone removal roller 4, which would adversely affect the feeding operation.

[0034] Large stones in the concrete will be filtered by the filter screen 3 and remain on the filter screen 3. The filter screen 3 is set at an angle on both sides, and the large stones will slide to both sides of the filter screen 3, so that the large stones come into contact with the stone removal roller 4.

[0035] When the device starts working, the motor 8 is started, and the drive shaft 9 drives the transmission shaft 10 through gears. At the same time, the drive shaft 9 and the transmission shaft 10 drive the stone removal roller 4 to rotate through the sprocket and chain. When the stone removal roller 4 is rotating, it pushes the large stones on the filter screen 3 into the stone receiving box 6 through the actuating teeth 41, thereby completing the cleaning of the large stones on the filter screen 3 and effectively preventing the accumulation of large stones from clogging the discharge of the filter screen 3.

[0036] After the filter screen 3 filters out the large stones in the concrete, the concrete enters the lower part of the main body 1. The motor 8 drives the spiral blade 12 synchronously through the drive shaft 9, so that the spiral blade 12 rotates on the receiving bottom 13 at the bottom of the main body 1. The concrete is concentrated on the receiving bottom 13. Through the rotation of the spiral blade 12, the concrete can be quickly supplied to the pump truck through the discharge port 14 for concrete transportation.

[0037] The above completes the working process of the anti-clogging pump truck receiving device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
