Description

Technical Field

[0001] This invention relates to the field of brick forming machine accessories technology, and in particular to a feeding device for a hydraulic brick forming machine. Background Technology

[0002] Concrete block forming machines are a type of construction machinery. They are professional brick-making equipment for producing concrete products. Different models of block forming machines are selected according to the production volume. Based on the investment scale, simple, optimized, refined, semi-automatic, and fully automatic block forming machine production lines can be selected. Therefore, various brick forming machines have emerged. For example, Chinese patent document CN202010905845.0 discloses a concrete block forming machine, which solves the problem that existing block forming machines all use a pressure head to extrude materials into a mold box from the top via hydraulic drive. The mold box rises using a lifting mechanism, the pressure head rises, and the feeding box returns to the hopper to discharge materials again for a cycle. This method has many disadvantages, including large vibrations that affect the machine's service life, uneven material output, and air holes that affect quality. This invention includes a shell; a stirring device is installed inside the shell, which is connected to a discharge device and a transmission device. A pressure plate device is installed on one side of the transmission device, and the stirring device is also connected to a forming device. By adopting a mechanical mechanism, the vibration caused by hydraulic drive is reduced. In addition, the discharge device can control precise material output and achieve automated material output. The forming device can break up air holes in the mold. However, existing brick-forming machines often have problems with the surface layer of concrete blocks during production. This is because the mixing device cannot reach the surface, making it difficult to compact the material during feeding. Consequently, during die casting, insufficient material feeding results in numerous pits and depressions on the surface. These problems include slightly deep, narrow, and elongated pits, as well as insufficient or inadequate material distribution. Consequently, the overall surface of the concrete blocks is not smooth or strong enough, resulting in poor surface quality. Summary of the Invention

[0003] Therefore, in view of the above problems, the present invention proposes a feeding device for a hydraulic brick machine that improves the quality of concrete block bricks, the surface smoothness, and the overall solidity of the brick body.

[0004] To solve this technical problem, the present invention adopts the following solution: a feeding device for a hydraulic brick machine, including a fabric cart, on which a base feeding trough and a surface feeding trough are provided. A stirring mechanism is provided in the base feeding trough, and a swinging mechanism for stirring the fabric is provided in the surface feeding trough. The swinging mechanism includes a fixed seat, a lifting mechanism, a support frame, a horizontal swinging unit, and a swinging frame. The fixed seat is horizontally movable on the fabric cart and located on the surface feeding trough. The support frame is vertically movable on the fixed seat via the lifting mechanism and is located above the surface feeding trough. The horizontal swinging unit is located on the support frame, and the output end of the horizontal swinging unit is connected to and drives each swinging rod of the swinging frame to extend into the surface feeding trough to stir the slurry.

[0005] Furthermore, the horizontal swing unit includes a lead screw motor, which is fixed on the support frame and its output end is connected to the swing frame, driving the swing frame to swing back and forth in the horizontal direction.

[0006] Furthermore, the horizontal swing unit includes an eccentric drive mechanism, a first connecting rod, and a second connecting rod. The eccentric drive mechanism is mounted on a support frame, and its eccentric output end is connected to one end of the first connecting rod. The second connecting rod is movably mounted on the moving slot of the support frame. The end of the first connecting rod away from the eccentric drive mechanism is hinged to the upper end of the second connecting rod, and the lower end of the second connecting rod is connected to the swing frame. The eccentric output end of the eccentric drive mechanism drives the second connecting rod to move eccentrically on the moving slot via the first connecting rod, thereby driving each swing rod of the swing frame to extend into the surface material feeding slot to swing and agitate the fabric.

[0007] Furthermore, it also includes a moving mechanism, which is mounted on a support frame and has a moving seat fixed at its output end. The support frame is provided with a second moving groove on the output end of the eccentric wheel of the eccentric drive mechanism for horizontal adjustment of the eccentric drive mechanism. The eccentric drive mechanism is fixed on the moving seat and the eccentric wheel of the eccentric drive mechanism passes through the second moving groove.

[0008] Furthermore, the movable groove on the support frame is elliptical.

[0009] Furthermore, the fabric cart is equipped with a pushing mechanism, and the fixed seat of the swing mechanism is located on the output end of the pushing mechanism. The pushing mechanism drives the fixed seat of the swing mechanism to move horizontally back and forth.

[0010] Furthermore, the stirring mechanism includes a drive unit and a stirring shaft that is connected to and drives the output end of the drive unit to rotate. The two ends of the stirring shaft are respectively inserted through bearing seats into the side of the base material discharge groove of the fabric cart. The bearing seats at both ends of the stirring shaft are protective bearing seats to prevent slurry from entering the bearing.

[0011] Furthermore, the protective bearing housing includes a bearing housing body, an air blowing mechanism, and a bearing mounted on the bearing housing body. The bearing housing body extends into the inner edge of the substrate unloading groove of the fabric cart to form a protective ring. The bearing housing body is provided with an air pipe connector leading to the inner diameter of the bearing housing body at the upper end of the protective ring. The air outlet of the air blowing mechanism is connected to the inlet of the air pipe connector. The bearing housing body is provided with an outlet leading to the inner diameter of the bearing housing body at the lower end of the protective ring.

[0012] Furthermore, the bottom of the inner diameter of the bearing housing is provided with a chamfered opening at the outlet.

[0013] Furthermore, a dustproof ring is also provided on the inner diameter of the bearing housing within the protective ring.

[0014] By adopting the aforementioned technical solution, the beneficial effects of this invention are as follows: By setting a swing mechanism that can be raised and lowered on the surface layer feeding trough, each swing rod of the swing frame of the swing mechanism can extend into the surface layer feeding trough to swing and stir the slurry. This avoids the problem of unevenness and pits in the surface layer after the concrete block bricks are formed because the slurry cannot be stirred and compacted. The feeding of the concrete block bricks surface layer is achieved by inserting and swinging multiple swing rods with adjustable position and depth, which can be used to stir the surface layer of the concrete block bricks. This allows the surface layer to be compacted, greatly improving the quality of the concrete block brick surface layer, improving the surface flatness, and making the surface layer and the entire brick body more solid. It can be widely promoted and applied. Through further design, an eccentric drive mechanism is used to drive the second link via the first link, causing eccentric movement on the moving groove. This, in turn, causes the swing rods of the swing frame to extend into the surface material feeding groove, swinging and agitating the fabric. This multi-directional swinging of the swing rods further improves the overall compaction effect of the surface material, enhancing the flatness and strength of the brick surface structure. The moving mechanism allows users to adjust the swing amplitude of the swing rods on the swing frame according to the size requirements of the brick surface, effectively ensuring balanced surface material feeding. The elliptical shape of the moving groove ensures that the swing rods of the swing frame do not swing along a straight line. The back-and-forth stirring enhances the agitation effect of the material. A pushing mechanism, in conjunction with the oscillating mechanism, effectively compacts the slurry on the upper and side surfaces of the brick, further improving the structural strength and flatness of the brick. Protective bearing seats prevent damage to the bearings at both ends of the mixing shaft due to slurry penetration, extending the service life of the bearing seats. An air-blowing mechanism cleans the front end of the bearing from top to bottom, expelling any penetrated slurry from the outlet, preventing further penetration and effectively protecting the bearings, thus extending their service life.

The pushing mechanism 13 is driven by the extension and retraction of the cylinder to move the pushing rod horizontally back and forth, thereby driving the fixed base 51 on the pushing rod to move horizontally back and forth. The support frame 53 is vertically movable and positioned on the fixed base 51 via the lifting mechanism 52, and the support frame 53 is located on the surface layer. Above the feeding trough 12, the lifting mechanism 52 drives the support frame 53 to move up and down, adjusting the depth of each swing rod 552 of the swing frame 55 inserted into the fabric layer.

[0021] In this invention, the substrate feeding trough and the surface layer feeding trough can also be two separate feeding troughs. The horizontal swing unit can also be a lead screw motor, that is, the lead screw motor is fixed on the support frame and the output end of the lead screw motor is connected to the swing frame to drive the swing frame to swing back and forth in the horizontal direction. This structure only swings in a straight line, so the overall stirring effect is not optimal. The moving mechanism of the horizontal swing unit can also be omitted. The moving mechanism is set to adjust the swing amplitude of the swing frame. The lifting mechanism can be a cylinder, a hydraulic cylinder, or a lead screw motor. The cylinder of the pushing mechanism can also be replaced by a hydraulic cylinder or a lead screw motor.
