Description
Technical Field
[0001] This invention relates to the field of construction machinery technology, specifically to a construction concrete mixing device with high-efficiency dust removal function. Background Technology
[0002] During construction, concrete mixing equipment generates a large amount of dust, which not only pollutes the environment but also endangers the health of operators.
[0003] In construction, it is often necessary to mix various materials in a certain proportion for subsequent use. During concrete mixing, materials are usually directly put into the mixing tank. However, since the raw materials generally contain various large hard impurities or lumps, hard impurities can easily damage the mixing paddle if put into the mixing tank, while lumps are not conducive to thorough mixing. Moreover, after the concrete is mixed, the mixing tank needs to be cleaned. Sometimes, the mixed materials accumulate on the inner wall of the mixing tank, making it difficult to clean. Summary of the Invention

A side connecting plate is fitted on the inner side of the inner fitting groove, and a transmission rod groove is opened on the fitting part of the side connecting plate. An outer fitting groove is provided at the contact point between the fitting part of the side connecting plate and the outer wall of the inner fitting groove. A vertical shaft is vertically installed in the middle of the extension plate, and a fifth motor is connected to the top of the vertical shaft. A first gear is fitted on the bottom of the vertical shaft.
[0008] The side connecting plate is attached to the inner wall of the mixing tank, the left sealing cover plate and the right sealing cover plate. Limiting sliders are installed on both sides of the outer wall of the side connecting plate, and the limiting sliders are engaged with the annular groove.
[0009] The transmission rod groove and the inner sleeve form a relative rotation structure;
[0010] The top of the mixing tank is connected to a hopper, and the top of the hopper is connected to a feeding box. The bottom of the feeding box is equipped with an inner filter screen, and the top of the feeding box is equipped with a top cover. The top of the top cover is equipped with a first motor, and the bottom of the first motor extends through the top cover with a first transmission rod. The outer wall of the first transmission rod is equipped with a flattening fan blade.
[0011] A feed pipe assembly is installed at one end of the outside of the mixing tank. A discharge inclined pipe is installed on the top wall of the outer wall of the spiral feeding pipe, and the discharge port of the discharge inclined pipe is connected to the feeding box. A filter-type dust suction interface is provided above the discharge port of the discharge inclined pipe, and a dust suction pipe is connected to the outer end of the filter-type dust suction interface.
[0012] Furthermore, the first gear and the second gear are connected by perpendicular meshing transmission.
[0013] Furthermore, the spiral feeding pipe is equipped with spiral auger blades inside, and a second motor is connected to the top of the spiral feeding pipe. A support frame is installed on the outside of the spiral feeding pipe.
[0014] Furthermore, a support frame is installed at the bottom of the mixing tank.
[0015] Furthermore, a water supply strip is embedded at the upper oblique part of the mixing tank, and a water supply pipe is installed at the water inlet of the water supply strip, and the water supply inlet of the water supply pipe is connected to a water tank and a pump.
[0016] Furthermore, a rotating shaft runs through the middle of the hopper, and an inner buckle plate is welded to the outer wall of the rotating shaft. One end of the rotating shaft is connected to a third motor.
[0017] Furthermore, the feeding size of the hopper and the size of the inner buckle plate are matched.
[0018] Furthermore, the discharge port of the feeding inclined tube and the filter-type dust suction interface are positioned in a mutually coordinated manner, and the feeding inclined tube is distributed in a downward inclined direction.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] 1. This invention uses a combination of a spiral feeding pipe and a feeding box for material feeding. The internal spiral auger blades are driven to rotate by a second motor, and the material is fed from the bottom. This method can reduce dust problems. The spiral feeding method provides relatively stable material feeding, which is directly introduced into the feeding box. The feeding box has an internal filter screen that can filter and separate the raw materials, removing large particles and lumps to avoid affecting the mixing effect.
[0021] The entire feeding box is sealed to reduce air circulation. When the material is fed through the inclined feeding tube, its position is coordinated with the filter-type dust collection interface. When the raw material falls from the inclined feeding tube, it forms a waterfall shape. The filter-type dust collection interface above can extract and isolate dust, effectively absorbing dust from all directions, reducing leakage and improving dust removal efficiency.
[0022] The surface of the inner filter screen is also equipped with ring-shaped flattening fan blades. Driven by the flattening fan blades, large particles and lumps of raw materials can be broken up and pushed to prevent them from affecting the filtration efficiency of the inner filter screen and thus prevent clogging.
[0023] The hopper serves two purposes: firstly, it temporarily stores the filtered raw materials; secondly, by controlling the drive of the third motor, the rotating shaft and inner buckle plate can be rotated, thereby controlling the opening and closing of the hopper and facilitating better batching and feeding operations.
[0024] 2. In this invention, sealing covers are provided on both sides of the mixing tank, and a limiting sleeve is provided at the center of the sealing cover;
[0025] A fourth motor is fixedly installed on the outside of the left sealing cover, and a transmission rod is inserted inward. By driving the mixing fan blades on the outer wall of the transmission rod, the raw materials inside can be broken up and mixed.
[0026] An inner sleeve is embedded inside the limiting sleeve, and the inner sleeve rotates within the limiting sleeve. A second gear is installed on the outer side of the inner sleeve away from the fourth motor. The inner sleeve can be mechanically rotated by the motor drive of the outer helical gear. An inner fitting groove is opened on the outer side of the inner sleeve, and a side connecting plate is engaged with the inner wall of the inner fitting groove on both sides, thereby driving the side connecting plate to rotate. The side connecting plate is attached to the inner wall of the mixing box, the left sealing cover plate and the right sealing cover plate, and can scrape the inner wall of the mixing box during rotation. It can thoroughly scrape the inner wall of the mixing box to clean the mixed materials on the inner wall of the mixing box, which is beneficial to the cleaning of the inner wall of the mixing box.
[0027] One end of the transmission rod is directly connected to the fourth motor through the inner sleeve, while the other end is embedded in the center of another set of inner sleeves. A bearing structure can be selected for auxiliary limiting. While ensuring the transmission stability of the transmission rod, the rotation of the inner sleeve is utilized. A side connecting plate is engaged on its outer side. The stability of the rotation structure of the side connecting plate is achieved by utilizing the fit between the side connecting plate and the inner wall of the mixing tank, as well as the limiting slider that fits with the annular groove on the inner wall of the sealing cover. Two sets of transmission structures are used to achieve relative rotation of the inner sleeves on both sides, so as to better mix and stir the internal raw materials. Attached Figure Description

[0042] The side connecting plate 906 is attached to the inner wall of the mixing tank 1, the left sealing cover plate 8 and the right sealing cover plate 9. Limiting sliders 907 are installed on both sides of the outer wall of the side connecting plate 906, and the limiting sliders 907 and the annular groove 10 are engaged.
[0043] The transmission rod groove 9061 and the inner sleeve 909 form a relative rotation structure;

The top of the top cover 201 is equipped with a first motor 202, and the bottom of the first motor 202 extends through the top cover 201 with a first transmission rod 204. The outer wall of the first transmission rod 204 is equipped with a flattening fan blade 205.
[0045] A feed pipe assembly 3 is installed at one end of the outer side of the mixing tank 1. A discharge inclined pipe 302 is installed on the top wall of the outer side of the spiral feeding pipe 301, and the discharge port of the discharge inclined pipe 302 is connected to the feeding box 2.

A support frame 304 is mounted on the outer side of the spiral feeding pipe 301. A pad frame 7 is installed at the bottom of the mixing tank 1; a water supply strip plate 5 is embedded at the upper diagonal of the mixing tank 1, and a water supply pipe 501 is installed at the water inlet of the water supply strip plate 5, and the water supply inlet of the water supply pipe 501 is connected to a water tank and a pump 502; a rotating shaft 601 runs through the middle of the feeding hopper 6, and an inner buckle plate 602 is welded to the outer wall of the rotating shaft 601, and a third motor 603 is connected to one end of the rotating shaft 601; the feeding size of the feeding hopper 6 and the size of the inner buckle plate 602 are matched; the discharge port of the feeding inclined pipe 302 and the filter-type dust suction interface 401 are matched in the upper and lower positions, and the feeding inclined pipe 302 is distributed in a downward inclined direction of 15 degrees.
[0046] The material is fed by the combination of spiral feeding pipe 301 and feeding box 2. The internal spiral auger fan blades are driven to rotate by the second motor 303. The bottom feeding method can reduce the occurrence of dust problems. The spiral feeding method is relatively stable and directly introduces the material into the feeding box 2. The feeding box 2 has an internal filter screen 203, which can filter and separate the raw materials, remove large particles and lumps, and avoid affecting the mixing effect.
[0047] The entire feeding box 2 is sealed, reducing air circulation. When the feeding inclined pipe 302 feeds the material, its position cooperates with the filter-type dust suction interface 401.

A second gear 904 is installed on the outer side of the inner sleeve 909 away from the fourth motor 802. The inner sleeve 909 can be mechanically rotated by the motor drive of the outer helical gear. An inner fitting groove 9091 is opened on the outer side of the inner sleeve 909. The inner walls of the inner fitting grooves 9091 on both sides are engaged with side connecting plates 906, thereby driving the side connecting plates 906 to rotate. The side connecting plates 906 are in contact with the inner walls of the mixing tank 1, the left sealing cover plate 8 and the right sealing cover plate 9. They can scrape the inner wall of the mixing tank 1 when rotating, which can fully scrape the inner wall of the mixing tank 1 to clean the mixed materials on the inner wall of the mixing tank 1, which is beneficial to the cleaning of the inner wall of the mixing tank 1.
[0053] One end of the transmission rod 803 is directly connected to the fourth motor 802 through the inner sleeve 909, while the other end is embedded in the center of another set of inner sleeves 909. A bearing structure can be selected for auxiliary positioning. While ensuring the transmission stability of the transmission rod 803, the rotation of the inner sleeve 909 is utilized.

The stability of the rotation structure of the side connecting plate 906 is achieved by utilizing the fit between the side connecting plate 906 and the inner wall of the mixing tank 1, as well as the limiting slider 907 that fits with the annular groove 10 on the inner wall of the sealing cover. By adopting two sets of transmission structures, the relative rotation of the inner sleeves 909 on both sides is achieved, so as to better mix and stir the internal raw materials.
