Description

Technical Field

[0001] This invention relates to the field of building material lifting technology, and in particular to a small building material lifting device for construction. Background Technology

[0002] Currently, most commonly used small lifting devices are driven by motors, belts, or chains, which move the loading platform or hopper for vertical transport.

[0003] The invention patent with authorization announcement number CN119503350B discloses a lifting device for cement processing, including a frame, a transmission component installed on the frame, a lifting shell that can move up and down reciprocally connected to the transmission component, a lifting component driven by the transmission component installed inside the lifting shell, an annular lifting belt and a toothed belt connected to the lifting component, the annular lifting belt and the toothed belt rotating in opposite directions, a set of regularly distributed lifting components installed on the annular lifting belt, and the lifting component including a hopper that engages with the annular lifting belt, with a feeding ramp fixedly provided at the bottom of the hopper.

[0004] However, the aforementioned invention patents still have drawbacks: the mechanical scraper mechanism has a complex structure and many transmission links, especially relying on the precise cooperation of reciprocating screws and gears, which not only results in high manufacturing and maintenance costs, but also easily creates dead angles during the scraping process, and has limited cleaning effect on highly adhesive materials; pneumatic cleaning requires a high-pressure air source and a periodically start-stop air pump, which not only increases energy consumption and equipment complexity, but also easily causes air circuit blockage or failure in long-term use in dusty environments, resulting in low reliability and inconvenient maintenance. Therefore, a small building material lifting device for construction is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing a small building material lifting device for construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A small building material lifting device for construction includes a shell. Two limiting mounting plates are fixedly connected to the inner walls of both sides of the shell. Two evenly distributed transmission shafts are rotatably connected between the two limiting mounting plates. Transmission wheels are fixedly connected to both ends of the transmission shafts. Lifting belts are slidably connected to the inner walls of the two limiting mounting plates. The lifting belts are sleeved on the outer walls of the two transmission wheels on the same side. Several sets of lifting mechanisms are provided on the side of the two lifting belts facing each other.

[0008] The lifting mechanism includes two connecting rods, which are fixedly connected to the lifting belts on both sides respectively. A rotating shaft is rotatably connected to the opposite side of the two connecting rods. An installation block is fixedly connected between the two rotating shafts. A loading bucket is fixedly connected to the top of the installation block. A spherical seat is installed inside the installation block. An agitator is slidably connected inside the spherical seat.

[0009] An angle adjustment gear is fixed to the outer wall of one of the rotating shafts. A sliding rack meshes with the outer wall of the angle adjustment gear. The side wall of the sliding rack is slidably connected to the connecting rod. A limit slide is slidably connected to the end of the sliding rack. The limit slide is set between two limit mounting plates. The two limit mounting plates and the limit slide are fixedly connected by a connecting block.

[0010] The tail end of the stirring rod is rotatably connected to a connecting seat, the bottom of the connecting seat is fixedly connected to a telescopic rod, the end of the telescopic rod is fixedly connected to a rotating gear through a one-way bearing, the outer wall of the rotating gear meshes with the tooth block assembly, and the outer wall of the tooth block assembly is fixedly connected to a loop-shaped limiting track.

[0011] Preferably, a sliding base plate is fixedly connected to the bottom of the loop-shaped limiting track, and a second spring is fixedly connected between the connecting seat and the rotating gear.

[0012] Preferably, the sliding base plate is slidably connected to slide rails on both sides, and the two slide rails are fixed to the same mounting bracket.

[0013] Preferably, the mounting bracket is fixedly connected to the mounting block, and a threaded rod is threadedly connected to the inner side of the sliding base plate. The bottom end of the threaded rod is rotatably connected to the mounting bracket, and a transmission gear is fixedly connected to the top end of the threaded rod.

[0014] Preferably, the outer wall of the transmission gear is engaged with an adjusting rack, and the adjusting rack is slidably connected to the mounting bracket.

[0015] Preferably, a stirring abutment rod is fixedly connected to the side of the connecting seat away from the second spring, a corrugated abutment rod is fixedly connected to the side of the limiting slide plate near the loading hopper, the corrugated abutment rod abuts against the stirring abutment rod, a lower abutment block is fixedly connected to the side of the corrugated abutment rod away from the limiting slide plate, and an upper abutment block is fixedly connected to the inner side of the housing, the lower abutment block and the upper abutment block are located on the same plane, and the upper abutment block is located diagonally above the lower abutment block.

[0016] Preferably, an outlet and an inlet are fixedly connected to both sides of the shell, and two symmetrically distributed guide plates are slidably connected to the top of the outlet. A first spring is fixedly connected between the two guide plates and the outlet.

[0018] Compared with existing technologies, the advantages of this invention are as follows:

[0019] This invention effectively breaks up material buildup and prevents blockages by continuously agitating the material in an elliptical motion during the conveying process, while simultaneously improving the uniformity of material mixing. Utilizing the telescopic movement of the agitator rod within the spherical seat, it effectively agitates the material while automatically scraping away any material adhering to the rod, achieving efficient self-cleaning without the need for additional pneumatic or complex scraping devices. Furthermore, through the cooperation of the limiting slide plate and the sliding rack, the posture changes of the loading hopper during lifting, unloading, and resetting are automatically controlled. The loading hopper adjusts its posture (tilting, vertical, etc.) during discharge, and residue on the inner wall is scraped off from the edge of the discharge port, ensuring no material accumulation in each cycle and guaranteeing stable material conveying and thorough unloading. The entire process requires only a single power source, significantly improving conveying efficiency and quality consistency while reducing equipment manufacturing difficulty, energy consumption, and maintenance requirements. It achieves efficient, clean, and stable continuous operation, and is particularly suitable for the continuous and efficient conveying of various granular, powdery, and slightly sticky building materials.

Therefore, they should not be construed as limitations on this invention.

[0033] Reference Figures 1-10 A small building material lifting device for construction includes a shell 1. Two limiting mounting plates 8 are fixedly connected to the inner walls of both sides of the shell 1. Two evenly distributed transmission shafts 13 are rotatably connected between the two limiting mounting plates 8. Transmission wheels 6 are fixedly connected to both ends of the transmission shafts 13. Lifting belts 7 are slidably connected to the inner walls of the two limiting mounting plates 8. The lifting belts 7 are sleeved on the outer walls of the two transmission wheels 6 on the same side. Several sets of lifting mechanisms are provided on the opposite side of the two lifting belts 7.

[0034] The lifting mechanism includes two connecting rods 11, which are fixedly connected to the lifting belts 7 on both sides respectively. A rotating shaft 22 is rotatably connected to the opposite side of the two connecting rods 11. An installation block 28 is fixedly connected between the two rotating shafts 22. A loading bucket 9 is fixedly connected to the top of the installation block 28. A spherical seat 20 is installed inside the installation block 28. An agitator 19 is slidably connected inside the spherical seat 20.

[0035] The two sides of the housing 1 are respectively fixedly connected to the discharge port 4 and the inlet port 3. The top of the discharge port 4 is slidably connected to two symmetrically distributed guide plates 5. The two guide plates 5 are respectively fixedly connected to the discharge port 4 with the first spring 30.

[0036] A drive motor 2 is fixedly connected to the outer wall of the housing 1, and the drive motor 2 is fixedly connected to one of the transmission shafts 13.

[0037] In this embodiment, building materials enter the loading hopper 9 through the feed inlet 3, are conveyed upwards by the lifting belt 7, and finally discharged from the discharge outlet 4. During this process, the drive motor 2 drives the two lifting belts 7 to operate synchronously through the transmission shaft 13, and drives the connecting rod 11 and its components to move in coordination, thereby achieving continuous material lifting.

[0038] Among them, the connecting seat 32 is fixedly connected to the side away from the second spring 31 with an agitating abutment rod 23, the limiting slide plate 14 is fixedly connected to the side near the loading hopper 9 with a corrugated abutment rod 15, the corrugated abutment rod 15 abuts against the agitating abutment rod 23, the corrugated abutment rod 15 is fixedly connected to the side away from the limiting slide plate 14 with a lower abutment block 18, the inner side of the housing 1 is fixedly connected with an upper abutment block 12, the lower abutment block 18 and the upper abutment block 12 are located on the same plane, and the upper abutment block 12 is located diagonally above the lower abutment block 18.

[0039] The outer wall of the transmission gear 29 is engaged with an adjusting rack 16, which is slidably connected to the mounting bracket 10.

[0040] Mounting bracket 10 is fixedly connected to mounting block 28. A threaded rod 27 is threadedly connected to the inner side of sliding base plate 25. The bottom end of threaded rod 27 is rotatably connected to mounting bracket 10, and a transmission gear 29 is fixedly connected to the top end of threaded rod 27.

[0041] In this embodiment, when running from bottom to top, the adjusting rack 16 contacts the lower abutment block 18, pushing the threaded rod 27 to move the sliding base plate 25 and its components upward, thereby causing the stirring rod 19 to extend from the spherical seat 20. As the stirring rod 19 enters the loading hopper 9 and continues to move upward, the stirring abutment rod 23 intermittently contacts the fixed corrugated abutment rod 15, causing the stirring abutment rod 23 to generate high-frequency reciprocating motion.

[0042] The tail end of the stirring rod 19 is rotatably connected to a connecting seat 32, the bottom of the connecting seat 32 is fixedly connected to a telescopic rod 36, the end of the telescopic rod 36 is fixedly connected to a rotating gear 35 through a one-way bearing, the outer wall of the rotating gear 35 meshes with the tooth block assembly 34, and the outer wall of the tooth block assembly 34 is fixedly connected to a loop-shaped limiting track 33.

[0043] A sliding base plate 25 is fixedly connected to the bottom of the loop-shaped limiting track 33, and a second spring 31 is fixedly connected between the connecting seat 32 and the rotating gear 35.

[0044] The sliding base plate 25 is slidably connected to the two sides of the sliding rails 26, and the two rails 26 are fixed to the same mounting bracket 10.

[0045] In this embodiment, the motion is transmitted to the stirring rod 19 and the spherical seat 20 via the connecting seat 32. Under the coordinated constraint of the rotating gear 35, the tooth block group 34, and the loop limiting track 33, the spherical seat 20 and the stirring rod 19 jointly perform a continuous and stable elliptical trajectory circular motion because the rotating gear 35 and the telescopic rod 36 are connected by a one-way gear. This motion mechanism effectively achieves thorough mixing of the material in the loading hopper 9 during the conveying process, preventing material accumulation or blockage, and improving the mixing uniformity and discharge smoothness.

[0046] After the agitating abutment rod 23 disengages from the corrugated abutment rod 15, the connecting seat 32 quickly resets under the elastic restoring force of the second spring 31. Simultaneously, the other end of the adjusting rack 16 contacts the upper abutment block 12, causing the entire assembly on the sliding base plate 25 to move downwards, retracting the agitating rod 19 into the spherical seat 20. During this process, the material adhering to the outer surface of the agitating rod 19 is thoroughly scraped off by the inner wall of the spherical seat 20, preventing residual material accumulation and ensuring equipment cleanliness and reliability for subsequent operation.

[0047] One of the rotating shafts 22 has an angle adjustment gear 21 fixedly connected to its outer wall. The outer wall of the angle adjustment gear 21 is meshed with a sliding rack 24. The side wall of the sliding rack 24 is slidably connected to the connecting rod 11. The end of the sliding rack 24 is slidably connected to a limiting slide plate 14. The limiting slide plate 14 is set between two limiting mounting plates 8. The two limiting mounting plates 8 and the limiting slide plate 14 are fixedly connected by a connecting block 17.

[0048] In this implementation plan, to ensure that the loading hopper 9 remains horizontal during the conveying process, as shown in the figure ( Figure 3 As the rotation radius of the limiting slide plate 14 gradually decreases, the sliding rack 24 slowly retracts, which in turn drives the angle adjustment gear 21 to adjust the posture of the loading hopper 9, ensuring the stability of the material during transportation. Subsequently, the rotation radius of the limiting slide plate 14 increases for the first time, pushing the sliding rack 24 to extend, causing the loading hopper 9 to gradually tilt and smoothly pour the material into the discharge port 4. The second increase in the rotation radius causes the loading hopper 9 to further turn into a vertical state. These two increases correspond to the two turning structures on the sides of the limiting slide plate 14, respectively.

[0049] Subsequently, the loading bucket 9 moves vertically downwards, and any material that may be adhering to the inner wall of the loading bucket 9 is effectively scraped off by the edge of the discharge port 4. The connecting rod 11 moves downwards at an angle along with the lifting belt 7, maintaining the same angle as the current side wall of the loading bucket 9, ensuring that the material inside the bucket is completely emptied. Then, the rotation radius of the limiting slide plate 14 returns to its initial value, and the loading bucket 9 returns to a horizontal state, ready to start a new round of material conveying cycle.

[0050] The working principle and usage of this invention are explained in detail below: After the building materials enter the loading hopper 9 through the feed inlet 3, they are conveyed upwards by the lifting belt 7 and finally discharged from the discharge outlet 4. During this process, the drive motor 2 drives the two lifting belts 7 to operate synchronously through the transmission shaft 13, and drives the connecting rod 11 and its components to move in coordination, thereby realizing the continuous lifting of materials.

[0051] When running from bottom to top, the adjusting rack 16 contacts the lower abutment block 18, pushing the threaded rod 27 to move the sliding base plate 25 and its components upward, thereby causing the agitator rod 19 to extend from the spherical seat 20. As the agitator rod 19 enters the loading hopper 9 and continues to move upward, the agitator abutment rod 23 intermittently contacts the fixed corrugated abutment rod 15, causing the agitator abutment rod 23 to generate high-frequency reciprocating motion.

[0052] The motion is transmitted to the stirring rod 19 and the spherical seat 20 via the connecting seat 32. Under the coordinated constraint of the rotating gear 35, the tooth block group 34, and the loop limiting track 33, the spherical seat 20 and the stirring rod 19 jointly perform a continuous and stable elliptical trajectory rotation motion because the rotating gear 35 and the telescopic rod 36 are connected by a one-way gear. This motion mechanism effectively achieves full mixing of the material in the loading hopper 9 during the conveying process, preventing material accumulation or blockage, and improving the mixing uniformity and discharge smoothness.

[0053] After the agitating abutment rod 23 disengages from the corrugated abutment rod 15, the connecting seat 32 quickly resets under the elastic restoring force of the second spring 31. Simultaneously, the other end of the adjusting rack 16 contacts the upper abutment block 12, causing the entire assembly on the sliding base plate 25 to move downwards, retracting the agitating rod 19 into the spherical seat 20. During this process, the material adhering to the outer surface of the agitating rod 19 is thoroughly scraped off by the inner wall of the spherical seat 20, preventing residual material accumulation and ensuring equipment cleanliness and reliability for subsequent operation.

[0054] During the conveying process, to ensure that the loading bucket 9 remains horizontal at all times, as shown in the figure ( Figure 3 As the rotation radius of the limiting slide plate 14 gradually decreases, the sliding rack 24 slowly retracts, which in turn drives the angle adjustment gear 21 to adjust the posture of the loading hopper 9, ensuring the stability of the material during transportation. Subsequently, the rotation radius of the limiting slide plate 14 increases for the first time, pushing the sliding rack 24 to extend, causing the loading hopper 9 to gradually tilt and smoothly pour the material into the discharge port 4. The second increase in the rotation radius causes the loading hopper 9 to further turn into a vertical state. These two increases correspond to the two turning structures on the sides of the limiting slide plate 14, respectively.

[0055] Subsequently, the loading bucket 9 moves vertically downwards, and any material that may be adhering to the inner wall of the loading bucket 9 is effectively scraped off by the edge of the discharge port 4. The connecting rod 11 moves downwards at an angle along with the lifting belt 7, maintaining the same angle as the current side wall of the loading bucket 9, ensuring that the material inside the bucket is completely emptied. Then, the rotation radius of the limiting slide plate 14 returns to its initial value, and the loading bucket 9 returns to a horizontal state, ready to start a new round of material conveying cycle.

[0056] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
