Description

Technical Field

[0001] The utility model relates to the technical field of concrete raw material conveying, in particular to a concrete raw material conveying device. Background Technique

[0002] Concrete is an engineering composite material in which a cementitious material binds aggregates into a whole. Usually, cement is used as the cementitious material, which is mixed with aggregates such as sand and stone in a certain proportion, and then water, additives and admixtures are added and stirred. Concrete is widely used in civil engineering.

[0003] For the mixing and preparation of concrete, the transported raw materials mainly include stones and powders. Continuous belt conveyors or lifting buckets are often selected for the transportation of stones, and screw conveyors are often selected for the transportation of cement and other additives; however, during the transportation of raw materials, whether due to the high moisture content of the raw materials themselves, the humid external environment, or the long storage time and improper transportation of the raw materials, it may cause the particles to stick to each other and form lumps. In this case, it will not only affect the efficiency of further material transportation, but also may cause quality problems during the concrete production process.

[0004] After retrieval, the Chinese utility model patent with the publication number CN212125252U discloses a transfer device for concrete raw material conveying, including a loading box. Two handles are fixedly connected above the rear end of the loading box. Groove two and groove one are respectively opened at the front ends of the two handles. A fixing column is fixedly connected to each of the left and right ends of the long column. A movable long rod two is sleeved on the fixing column at the right end of the long column, and a movable long rod one is sleeved on the fixing column at the left end of the long column. This application transports materials by loading them in the loading box. However, due to the open design of the loading box of this device, there is a greater possibility that the safety of the materials will be affected by the external environment during the transfer and transportation of the materials, such as moisture caking, mixing pollution, dust dispersion, etc. Content of the Utility Model

[0005] Aiming at the above-mentioned prior art, the utility model aims to provide a concrete raw material conveying device, and the main technical problem to be solved is how to ensure the safety of the concrete raw materials during transfer and transportation.

[0006] To achieve the above object, the technical solution of the embodiment of the utility model is realized as follows:

[0007] A concrete raw material conveying device includes a vehicle body, a rotating drum and a driving mechanism are arranged on the vehicle body, and the vehicle body transports raw materials through the rotating drum. The rotating drum includes a barrel body and a housing. A plurality of cross bars are arranged inside between the barrel body and the housing, and a plurality of claw nails are arranged on the inner wall of the barrel body. The rotating drum breaks up the raw materials through the cross bars and claw nails, and the driving mechanism is used to drive the rotating drum to rotate.

[0008] Furthermore, side plates and support plates are respectively and fixedly connected to both sides of the top end of the vehicle body. The rotating cylinder is located between the side plate and the support plate.

[0009] Furthermore, the housing is in a horn shape, and the thick-mouth end of the housing is fixedly connected to the barrel body. A material pipe is fixedly connected to the thin-mouth end of the housing. The material pipe is adapted to the groove, and a sealing cover is provided at the pipe orifice of the material pipe. The tip of the claw nail is curved.

[0010] Furthermore, a circular opening is formed at the top end of the plate body of the support plate, and a connecting shaft is rotatably connected to the support plate at the circular opening. One end of the connecting shaft close to the barrel body is fixedly connected to a support plate, and a driven wheel is key-connected to the other end of the connecting shaft.

[0011] Furthermore, a plurality of bolts are equidistantly and fixedly connected to the middle part of one side of the barrel body. A plurality of circular through holes are equidistantly formed on the outer side of the plate body of the support plate. The number of the bolts is the same as that of the circular through holes and they correspond to each other one by one. The bolts penetrate through the support plate at the circular through holes, and nuts are threadedly connected to the ends of the bolts.

[0012] Furthermore, the driving mechanism includes a motor. The motor is fixedly connected to one side of the top end of the vehicle body close to the connecting shaft.

[0027] Embodiment 1

[0028] Referring to the attached Figures 1-3 , this application provides a concrete raw material conveying device, including a vehicle body 1. A rotating drum 3 and a driving mechanism are provided on the vehicle body 1, and the vehicle body 1 transports and conveys raw materials through the rotating drum 3. Therefore, after the rotating drum 3 is closed with a sealing cover, the inside of the rotating drum 3 can be made into a closed environment. In this case, it is possible to avoid the influence of external air flow, moisture, sundries, etc. on the raw materials, such as dust generation, caking, pollution, etc., so as to ensure the safety of the raw material transportation. The rotating drum 3 includes a barrel body 301 and a housing 302. A number of cross bars 3012 are provided inside the barrel body 301 and the housing 302. The cross bars 3012 are arranged in a circular array inside the barrel body 301 and the housing 302, and both ends of the cross bars 3012 are fixedly connected to the inner walls of the barrel body 301 and the housing 302 respectively. A number of claw nails 3011 are provided on the inner wall of the barrel body 301. The rotating drum 3 disperses the raw materials through the cross bars 3012 and the claw nails 3011. The driving mechanism is used to drive the rotating drum 3 to rotate. When the rotating drum 3 rotates, the raw materials will gradually rise along with the rotation of its inner wall until they reach a certain height and then fall. That is, during the falling process of the raw materials, the cross bars 3012 can collide with the raw materials to disperse the raw materials. After that, the raw materials continue to fall and will contact the claw nails 3011, and the tips of the claw nails 3011 can further disperse the raw materials to avoid material caking. The tips of the claw nails 3011 are curved, and the bending direction of the tips of the claw nails 3011 is opposite to the rotation direction of the rotating drum 3. Therefore, it can be ensured that when the raw materials fall in a parabola, they can directly act on the tips of the claw nails 3011.

[0029] Preferably, side plates 2 and support plates 6 are fixedly connected to both sides of the top end of the vehicle body 1 respectively. The rotary drum 3 is located between the side plate 2 and the support plate 6. The side plate 2 and the support plate 6 are used to support the rotary drum 3 and provide conditions for its rotation and stable support. A semi-circular groove is formed at the top end of the support plate 6, and a hoop 4 is provided above the groove at the top end of the support plate 6. The space formed by the groove and the hoop 4 is used to provide a limiting effect on the material pipe 5, ensuring that it will not shift during the rotation process and cause instability of the rotary drum 3. The housing 302 is in a horn shape. After filling the material into the rotary drum 3, the horn-shaped housing 302 can ensure that there is a height difference between the material pipe 5 and the bottom surface of the barrel body 301. Therefore, the material will not stay at the material pipe 5. When the rotary drum 3 is inverted to take the material, the horn-shaped housing 302 can converge the material and discharge it more concentratedly. The thick end of the housing 302 is fixedly connected to the barrel body 301, and the thin end of the housing 302 is fixedly connected to the material pipe 5. The material pipe 5 is adapted to the groove, and a sealing cover is provided at the pipe orifice of the material pipe 5. A rope body is connected between the sealing cover and the material pipe 5, so as to prevent the loss of the sealing cover during the process of taking and placing the material.

[0030] Preferably, a circular opening is formed at the top end of the plate body of the support plate 6, and a connecting shaft 12 is rotatably connected to the support plate 6 at the circular opening. One end of the connecting shaft 12 close to the barrel body 301 is fixedly connected to a support plate 9, and the other end of the connecting shaft 12 is key-connected to a driven wheel 13. A plurality of bolts 11 are fixedly connected to the middle part of one side of the barrel body 301 at equal intervals. A plurality of circular through holes are formed at equal intervals on the outer side of the plate body of the support plate 9. The number of the bolts 11 is the same as that of the circular through holes and they correspond to each other one by one. The bolts 11 penetrate through the support plate 9 at the circular through holes, and nuts 10 are threadedly connected to the ends of the bolts 11. Through the threaded connection between the nuts 10 and the bolts 11, the detachable connection between the support plate 9 and the barrel body 301 can be realized, so as to facilitate the process of taking and placing the material of the rotary drum 3.

[0031] Preferably, the driving mechanism includes a motor 102. The motor 102 can be a servo motor, so the rotation speed of the rotary drum 3 can be controlled by the servo motor to ensure the effect of dispersing the raw materials. The motor 102 is fixedly connected to one side of the top end of the vehicle body 1 close to the connecting shaft 12. One end of the output shaft of the motor 102 is key-connected to a driving wheel 15. Both the driving wheel 15 and the driven wheel 13 are belt wheels, and the same belt 14 is sleeved outside the driving wheel 15 and the driven wheel 13. The diameter of the driving wheel 15 is smaller than that of the driven wheel 13. Using the smaller-diameter driving wheel 15 to drive the larger-diameter driven wheel 13 to rotate can achieve a deceleration effect. Therefore, the rotation speed of the rotary drum 3 can be controlled not to be too fast to generate centrifugal force, and further the effect of the raw materials tumbling in it is poor.

[0032] Preferably, the top of the vehicle body 1 is fixedly connected with support rods 7 on both sides below the cylinder body 301, and the tops of the two support rods 7 are fixedly connected with supports 8. The two supports 8 are arc-shaped, and the curvature of the supports 8 is the same as the curvature of the surface of the cylinder body 301. The supports 8 can be fitted on the outer wall of the cylinder body 301 to support it, thereby ensuring the convenience of installing the rotating drum 3 and the stability of rotating it. Universal wheels 101 are fixedly connected at the four corners on the outside of the bottom end of the vehicle body 1. The universal wheels 101 are used for moving the device, and the brakes on the universal wheels 101 can be used to maintain the stability of the device after moving, so as to ensure the convenience of transporting and conveying raw materials.

[0033] Working principle: When using this device to transport concrete raw materials, the raw materials can be loaded into the rotating drum 3, and after the sealing cover is covered, it can be placed on the two supports 8, and at the same time, it is ensured that the material pipe 5 is placed on the support plate 6, and the bolt 11 can penetrate the support plate 9. After that, the material pipe 5 can be limited by the clamp 4 on the one hand, and the nut 10 is threadedly connected to the bolt 11 on the other hand, so that the support plate 9 and the cylinder body 301 are in a fixed connection state;

[0034] After that, the motor 102 can be connected to an external power source and started, the motor 102 drives the driving wheel 15 to rotate, the driving wheel 15 drives the driven wheel 13 to rotate through the belt 14, and the driven wheel 13 drives the drum body 301 to rotate through the connecting shaft 12, so that the rotating drum 3 can roll the material inside by its own rotation;

[0035] Since the material tumbles by first rising along with the inner wall of the drum 3 and then falling down after reaching a certain height, the cross bar 3012 can be used to cause collision with the material during the falling process, thereby breaking up the material. After that, the material continues to fall and touches the claw nail 3011, so the tip of the claw nail 3011 can further disperse the material, thereby avoiding material agglomeration.

[0036] Example 2

[0037] See attached Figure 4 The present application provides a concrete raw material conveying device. Compared with Example 1, in order to ensure the smooth rotation of the rotating drum 3, a plurality of spherical grooves are equidistantly provided on the inner side of the support 8, and a ball 801 is provided in each spherical groove of the support 8. The ball 801 can reduce the friction between the rotating drum 3 and the support 8 when the rotating drum 3 rotates, thereby enabling the rotating drum 3 to rotate more smoothly.

[0038] Working principle: After the ball 801 is arranged on the inner wall of the support 8, the ball 801 can be used to replace the support 8 to contact the drum 3, and the rotation of the ball 801 can reduce the friction between the drum 3 and the support 8 when the drum 3 rotates, thereby making the rotation of the drum 3 smoother.
