Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a rotatable construction material feeder. Background Technology

[0002] In various construction projects, it is often necessary to vertically or inclinedly lift building materials (such as sand, gravel, concrete, bricks, mortar, etc.) piled on the ground or at low levels to higher work platforms (such as floors or operating levels) for construction use. Currently, a common method used in the industry is to use a material hoist (or material lifting machine) to accomplish this lifting task. The basic structure and working principle of this type of traditional material hoist are usually as follows: a relatively fixed support structure is built or installed on site as the main support, supplemented by an electric winch. The electric winch provides lifting power by winding or releasing the steel wire rope (or chain) on it. The lower end of the steel wire rope (or chain) is connected to a hopper for holding building materials, thereby hoisting the building materials from a lower level to a higher platform for construction.

[0003] For example, a construction material loading machine published by Chinese Patent Publication No. CN217025102U uses a slider to slide along the surface of a lead screw, which moves the support and lifts the pallet to a high position. The hydraulic cylinder is then activated to push the support rod to slide along the inner wall of the support, moving the pallet horizontally to the target platform. This replaces the method of manually pulling ropes to lift building materials, reducing labor, saving time and effort, and improving work efficiency.

[0004] However, the above-mentioned device has drawbacks: its degree of freedom is limited, the hopper can only move up and down and near and far, and the accuracy of the feeding position is not easy to control; the base support effect is poor and unstable, and it is easy to rotate and deviate during the feeding process. The hopper is prone to rotating and colliding with the building, and its poor stability can easily cause safety accidents. In addition, it is inconvenient to move the material out of the hopper, the position is very limited, and it is inconvenient to unload and other operations. Utility Model Content

[0005] The purpose of this utility model is to provide a rotatable building material feeder with multiple degrees of freedom, which can flexibly adjust the position of the hopper components, making the feeding position accurate, with the advantages of good stability and convenient unloading, ensuring the safety of the feeding process, and enhancing the vertical transportation efficiency of building materials, making the transportation process more stable and efficient.

[0031] The specific embodiments of this utility model will be described in more detail below with reference to the schematic diagrams. The advantages and features of this utility model will become clearer from the following description. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0032] The preferred embodiments of this utility model are given below with reference to the accompanying drawings and described in detail.

[0033] Figure 1 This is an isometric drawing of a rotatable building material feeder according to an embodiment of the present invention. Figure 2 This is a schematic diagram of a rotatable building material feeder according to an embodiment of this utility model. Please refer to it. Figure 1 and Figure 2 This utility model provides a rotatable building material feeder, including a rotating base 2, a column assembly, a crossbeam arm 6, and a hopper assembly. The crossbeam arm 6 extends horizontally. The hopper assembly is used to hold materials and is connected to the crossbeam arm 6. The hopper assembly can move along the crossbeam arm 6 to adjust its horizontal position.

[0034] The column assembly is rotatably mounted on the rotating base 2. The column assembly includes a column body 4 and a lifting assembly 5. The lifting assembly 5 includes a lifting part and a fixing part. The lifting part can move up and down along the column body 4. The fixing part is connected to the column body 4. The crossbeam arm 6 is connected to the lifting part.

[0035] For further details, please refer to... Figure 3 and Figure 4 The rotating base 2 includes a fixed base 21, a rotating assembly 3, and a driving assembly mounted on the fixed base 21. The rotating assembly 3 can rotate on the fixed base 21. The rotating assembly 3 includes a rotating platform 31, and a column assembly is mounted on the rotating platform 31. The driving assembly includes a driving gear 32 and a first motor 37. The outer circumference of the rotating platform 31 is provided with teeth that mesh with the driving gear 32. The first motor 37 drives the driving gear 32 to rotate, thereby driving the rotating platform 31 to rotate. For example, the fixed base 21 can be a hollow structure with an internal cavity, such as... Figure 4 As shown, the top of the fixed base 21 is provided with a clearance hole to allow space for the rotary table 31 and the drive gear 32. The rotating assembly 3 also includes a rotating shaft 39, which is fixedly connected to the bottom of the rotary table 31 (or the rotating shaft 39 is integrally formed with the rotary table 31) and coaxial with the rotary table 31. The rotating shaft 39 is located in the cavity of the fixed base 21, and the lower end of the rotating shaft 39 is rotatably connected to the bottom of the fixed base 21. A bearing seat hole is machined in the bottom of the fixed base 21, and the lower end of the rotating shaft 39 is connected to the bottom of the fixed base 21 through a rolling bearing.

[0036] Please refer to Figure 4 The fixing part includes a second motor 54 and a drive screw 53 driven by the second motor 54. The second motor 54 is connected to the rotary table 31, and the column body 4 is also connected to the rotary table 31. Therefore, the fixing part is connected to the column body 4 through the rotary table 31. The lifting part includes a lifting sleeve 51 sleeved on the drive screw 53. Preferably, the drive screw 53, the rotary table 31, the rotating shaft 39, and the lifting sleeve 51 are coaxially arranged. The inner wall of the lifting sleeve 51 is provided with an internal thread that mates with the drive screw 53. One end of the lifting sleeve 51 extends out of the column body 4 and connects to the crossbeam arm 6, thereby adjusting the height of the crossbeam arm 6 by lifting the lifting sleeve 51, and thus adjusting the height of the hopper assembly. It is understood that... Figure 2 The image shows the lowest position of beam arm 6.

[0037] Furthermore, the lifting unit includes a limiting block 52 connected to the lifting sleeve 51. For example, the column body 4 may have an inner cavity for accommodating the lifting assembly 5. This inner cavity may be an open cavity. The cavity wall of the column body 4 is provided with a limiting guide groove 41 for the limiting block 52 to slide. The groove wall of the limiting guide groove 41 is used to limit the limiting block 52, thereby restricting the lifting stroke of the lifting sleeve 51. Specifically, the upper and lower groove walls of the limiting guide groove 41 play a limiting role. At the same time, the limiting guide groove 41 also serves to guide the movement of the lifting sleeve 51.

[0038] Preferably, the construction material feeder includes a counterweight assembly, which includes a counterweight base 34 and a counterweight block 35 located on the counterweight base 34. It is understood that the weight of the counterweight block 35 can be flexibly adjusted according to site conditions, such as the weight of the material in the hopper assembly. The counterweight base 34 is connected to the column body 4 to improve the stability of the rotating base 2 during rotation and enhance the stability of the construction material feeder. Preferably, the counterweight assembly includes a connecting rod 33, and the counterweight base 34 is connected to the column body 4 via the connecting rod 33. The bottom of the counterweight base 34 is provided with a first slider 38, and the rotating base 2 is provided with an annular groove 36 for cooperating with the first slider 38. That is, the top of the fixed base 21 is provided with an annular groove 36, and the clearance hole at the top of the fixed base 21 is opened within the range of the annular groove 36. Figure 4 As shown, when the rotary table 31 rotates, the first slider 38 moves in a circular motion along the annular groove 36. The hopper assembly is located on one side of the column assembly, and the counterweight 34 is located on the other side of the column assembly away from the hopper assembly, so as to balance the forces on the opposite sides of the column assembly and make the building material feeder more stable.

[0039] Please refer to Figure 5The construction material feeding machine includes a screw drive assembly 7, which is mounted on a crossbeam arm 6. Specifically, the crossbeam arm 6 has a through groove 73 for mounting the screw drive assembly 7, meaning the through groove 73 extends vertically through the crossbeam arm 6. The screw drive assembly 7 includes a third motor 72 and a slide 74. The screw drive assembly 7 also includes a lead screw or threaded rod connected to the third motor 72. The slide 74 has a threaded hole that mates with the lead screw or threaded rod and is fitted onto the lead screw or threaded rod. The slide 74 is connected to a hopper assembly. The third motor 72 drives the lead screw or threaded rod to rotate, thereby causing the slide 74 to move along the lead screw or threaded rod, i.e., along the crossbeam arm 6. This embodiment uses the motor 72 connected to the lead screw 71 as an example.

[0040] Preferably, the construction material feeder includes a hydraulic cylinder assembly 8, which is movably connected to a crossbeam arm 6. The crossbeam arm 6 is connected to a hopper assembly via the hydraulic cylinder assembly 8, allowing adjustment of the hopper assembly's height. Specifically, one end of the hydraulic cylinder assembly 8 is connected to a slide 74, and the other end (the bottom telescopic end) is used to connect to the hopper assembly. It is understood that the hydraulic cylinder assembly 8 can fine-tune the height position of the hopper assembly.

[0041] For further details, please refer to... Figure 6The hopper assembly includes a hopper body 9, a lifting rope 10, a loading trolley 92, and a discharge plate 91. The discharge plate 91 is hinged to the bottom of the hopper body 9. The discharge plate 91 can be closed with the hopper body 9 to form a cavity for holding materials. For example, the angle of movement of the discharge plate 91 is 0° to 90° (the angle with the horizontal plane). When the discharge plate 91 and the hopper body 9 are closed (when the discharge plate 91 is at 90° with the horizontal plane), a rectangular cavity is formed. The discharge plate 91 can be opened to the same plane as the bottom surface of the hopper body 9 (when the discharge plate 91 is at 0° with the horizontal plane) so that the loading trolley 92 can be moved from the hopper body 9 to the discharge plate 91. The hopper body 9 is movably connected to the crossbeam arm 6 via the lifting rope 10. Preferably, the hopper assembly further includes a lifting plate 95, and the number of lifting ropes 10 is three or more to ensure the balance of the hopper body 9. In this embodiment, four lifting ropes 10 are used as an example. The connection points of the lifting ropes 10 and the hopper body 9 are evenly distributed on the hopper body 9. Similarly, the connection points of the lifting ropes 10 and the lifting plate 95 are evenly distributed on the lifting plate 95. The lifting plate 95 is then connected to the bottom telescopic end of the hydraulic cylinder assembly 8. More preferably, the hopper assembly also includes an electric slide rail system, which includes a track 94, a drive slider 93, a fourth motor, and a controller. The hopper assembly also includes a lead screw or other transmission mechanism. Tracks 94 are provided on the bottom surface of the hopper body 9 and on the unloading plate 91, and the track 94 on the bottom surface of the hopper body 9 is connected to the track 94 on the unloading plate 91. A drive slider 93 that cooperates with the track 94 is provided at the bottom of the loading platform 92. The fourth motor is built into the electric slide rail system and drives the slider 93 to move through a drive lead screw (such as a trapezoidal lead screw) or other transmission mechanism. The controller is electrically connected to the fourth motor, thereby controlling the fourth motor. The drive slider 93 is a linearly movable part of the electric slide rail system. The drive slider 93 cooperates with the track 94 and is driven by the fourth motor to slide on the track 94. The drive slider 93 internally includes threaded holes, rolling bearings, balls, and other structures to cooperate with a lead screw or other transmission mechanism to achieve precise movement. During loading, the loading trolley 92 moves outward from the hopper body 9 via the drive slider 93 on the track 94, achieving extended loading and unloading of materials and facilitating loading and unloading operations for workers. After reaching the loading height, the height position of the hopper assembly can be finely adjusted via the hydraulic cylinder assembly 8, opening the unloading plate 91 and making it flush with the bottom surface of the hopper body 9. The drive slider 93 at the bottom of the loading trolley 92 extends outward from the hopper body 9 on the track 94, thereby transporting the material outward through the loading trolley 92. This facilitates the loading and unloading of materials and solves the problems of existing feeding machines being unable to move materials outward, having limited positions, and being inconvenient for unloading.

[0042] The construction material loading machine includes a frame 1 and rollers 11. The rollers 11 are installed at the bottom of the frame 1, and the rotating base 2 is installed on the frame 1. In use, the frame 1 is pulled to the construction material loading location, then the position of the frame 1 is fixed, and the construction material is loaded onto the loading trolley 92 inside the hopper body 9. After the building materials are loaded and stabilized, the lateral feeding position of the hopper body 9 is first adjusted by the screw transmission assembly 7. The third motor 72 is started to drive the lead screw 71 to rotate, which drives the hopper body 9 to move horizontally to the required lateral position via the slide block 74. Then, the vertical feeding height of the hopper body 9 is adjusted by the lifting assembly 5. The second motor 54 is started to drive the drive screw 53 to rotate. After the drive screw 53 rotates, it drives the lifting sleeve 51 to move up and down inside the column body 4. After reaching the feeding height, the unloading plate 91 is opened so that the unloading plate 91 is flush with the bottom surface of the hopper body 9. The drive slider 93 at the bottom of the loading trolley 92 is started to extend outward from the hopper body 9 on the track 94, thereby transporting the materials outward by the loading trolley 92. This facilitates the loading and unloading of materials and solves the problems of existing feeding machines that cannot move materials outward, have limited positions, and are inconvenient for unloading. Preferably, the hopper body 9 is also equipped with a locking device to limit the maximum distance that the cargo cart 92 can be transported outward, and to prevent the cargo cart 92 from falling out of the hopper body 9.

[0043] When the hopper body 9 needs to be rotated and adjusted during use, the first motor 37 can be started. The first motor 37 drives the drive gear 32 to rotate, and the drive gear 32 drives the rotary table 31 to rotate, thereby driving the column assembly to rotate. While the column assembly is rotating, the hopper body 9 is also rotated 360°. During the rotation of the column assembly, the counterweight seat 34 is also driven to rotate on the rotating base 2 through the connecting rod 33. By adding a counterweight block 35 to the counterweight seat 34, the stability of the rotating assembly 3 during rotation can be improved.

[0044] As configured above, this utility model is equipped with a rotating base 2, which enables the rotation of the crossbeam arm 6; a lifting component 5 is provided in the column assembly, which enables the raising and lowering of the crossbeam arm 6; the hopper assembly can move along the crossbeam arm 6, thereby allowing the horizontal position of the hopper assembly to be adjusted along the direction of the crossbeam arm 6; the column body 4 is connected to a counterweight component, which improves the stability of the building material feeder, making it less prone to rotational deviation during the feeding process, providing good support and ensuring the safety of the feeding process; the hopper body 9 is equipped with a loading trolley 92, and the unloading plate 91 can be opened to the same plane as the bottom surface of the hopper body 9, allowing the loading trolley 92 to move from the hopper body 9 to the unloading plate 91, solving the problem in the prior art that the feeding machine cannot move materials out of the hopper, thus facilitating unloading. In summary, the construction material feeding machine of this utility model has multiple degrees of freedom, which can flexibly adjust the position of the hopper components, making the feeding position accurate. It has the advantages of good stability and convenient unloading, which can ensure the safety of the feeding process and enhance the vertical transportation efficiency of construction materials, making the transportation process more stable and efficient.
