[0001] This utility model belongs to the field of material transfer equipment, specifically relating to a tiltable and separating lifting mixing hopper. Background Technology

[0002] In the fields of industrial production and material handling, hoppers play an important role as common material transportation and storage equipment, especially in processes involving the mixing of multiple materials. The hopper is responsible for transferring materials from other feeding equipment to the mixing equipment, which involves feeding, hopper transportation, hopper lifting, and feeding. The traditional structure adopts a hopper structure with closed valves at both the top and bottom. The two closed valves at the top and bottom of the hopper are used to control the inlet and outlet, respectively. In addition, the transportation of the hopper relies on the hopper trolley. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a tiltable and separating lifting mixing hopper.

[0004] The technical solution adopted by this utility model is as follows: a tiltable and separable lifting mixing hopper, including a hopper, a lifting mechanism, and a hopper trolley. The hopper includes a hopper body, a sealed valve at the bottom of the hopper body, and rotating shafts fixedly connected to both sides of the hopper body, with bearing seats connected to the rotating shafts. The rotating shafts can rotate freely relative to the bearing seats.

[0005] The lifting mechanism includes a lifting fork that can be raised and lowered, and a first support arm is provided on the lifting fork. The first support arm is used to support the rotating shafts on both sides of the hopper body.

[0006] The hopper trolley includes a trolley body, with second support arms formed on the upper ends of both sides of the trolley body. The second support arms are used to support the bearing seats on both sides of the hopper body.

[0007] The first support arm is provided with a limiting seat, and the rotary shaft is limited by the limiting seat so that the rotary shaft cannot rotate relative to the first support arm.

[0008] The rotating shaft is provided with a mating shaft section with a regular hexagonal cross section. The limiting seat has two limiting support inclined surfaces with a 120-degree included angle. The two adjacent outer surfaces of the mating shaft section cooperate with the two limiting support inclined surfaces to form a limiting fit.

[0009] The limiting bracket includes two trapezoidal support blocks. The upper surface of the trapezoidal support block is inclined at 30 degrees relative to the horizontal plane to form a limiting support slope. The two trapezoidal support blocks are separated by a certain distance.

[0010] The limiting bracket includes two limiting blocks, and the side of the limiting block closest to the trapezoidal support block is a blocking surface perpendicular to the horizontal plane.

[0011] The bearing housing has a flat bottom, and the second support arm has a support plane at its upper end.

[0012] The upper end of the second support arm is fixed with a bearing housing mounting bracket, and the upper end of the bearing housing mounting bracket forms a support plane for supporting the bearing housing.

[0013] The bearing housing and the bearing housing mounting bracket are fixedly connected by threaded fasteners.

[0014] A flip positioning bracket is fixed on one or two rotating shafts. Each of the two ends of the flip positioning bracket is provided with a positioning slot. The second support arm is provided with a through positioning pin hole. When the positioning pin hole is opposite to the two positioning slot holes, the sealing valve is respectively facing upward and downward.

[0015] It is equipped with a flip-positioning pin, which is used to pass through the positioning pin hole and insert into the positioning slot hole.

[0016] The beneficial effects of this utility model are as follows: The hopper of this utility model can rotate relative to the bearing seat. After the bearing seat is fixed, the hopper can be flipped so that the sealing valve is upward for feeding or downward for discharging, thereby reducing the number of sealing valves.

Detailed Implementation

[0031] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0032] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0033] The directional and positional terms used in this utility model, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0034] like Figure 1 , Figure 2 As shown, a tiltable and separable lifting mixing hopper includes a hopper 100, a lifting mechanism 200, and a hopper trolley 300. The hopper 100 and the lifting mechanism 200 are separable, and the hopper 100 and the hopper trolley 300 are also separable. That is, the hopper 100 can be supported on the lifting mechanism 200 and the lifting mechanism 200 can realize the lifting and lowering of the hopper 100, and the hopper 100 can also be supported on the hopper trolley 300 and the hopper trolley 300 can realize the transfer of the hopper 100.

[0035] Furthermore, such as Figure 3 , Figure 4 As shown, the hopper 100 includes a hopper body, a sealing valve 110 at the bottom of the hopper body, and a rotating shaft 120 fixedly connected to both sides of the hopper body, with a bearing seat 130 connected to the rotating shaft 120. The rotating shaft 120 can rotate freely relative to the bearing seat 130. The rotating shaft 120 of the hopper 100 is fixedly connected to the hopper body, meaning that the two rotate synchronously. Rotating the rotating shaft 120 will cause the hopper body to rotate. The rotating shaft 120 is fitted with a bearing seat 130, which is a support with an internal bearing. The internal bearing is engaged with the outer circumference of the rotating shaft 120, allowing the rotating shaft 120 to rotate freely relative to the bearing seat 130. Thus, when supporting the bearing seat 130, the rotating shaft 120 and the hopper body can rotate freely, causing the sealing valve 110 to be positioned upwards or downwards, thereby enabling the hopper 100 to rotate freely.

[0036] like Figure 5 , Figure 6 As shown, the lifting mechanism 200 includes a lifting fork 210 that can be raised and lowered. The lifting fork 210 is provided with a first support arm 220, which is used to support the rotary shafts 120 on both sides of the hopper body. The two first support arms 220 of the lifting fork 210 cooperate with the rotary shafts 120 on both sides of the hopper body, and the lifting and lowering of the hopper 100 is realized by supporting the rotary shafts 120 on both sides of the hopper body.

[0037] Furthermore, such as Figure 7-9As shown, the first support arm 220 is provided with a limiting seat 230. The rotary shaft 120 is limited and engaged with the limiting seat 230, preventing the rotary shaft 120 from rotating relative to the first support arm 220. Specifically, the rotary shaft 120 is provided with a mating shaft section 121 with a regular hexagonal cross-section. The limiting seat 230 has two limiting support inclined surfaces 231 with an included angle of 120 degrees. The two adjacent outer surfaces of the mating shaft section 121 engage with the two limiting support inclined surfaces 231 to form a limiting engagement. Further, the limiting seat 230 includes two trapezoidal support blocks 232. The upper end face of the trapezoidal support block 232 is inclined at 30 degrees relative to the horizontal plane to form the limiting support inclined surface 231. The two trapezoidal support blocks 232 are spaced a certain distance apart. This configuration can accommodate rotary shafts 120 of a certain size range without requiring precise fitting.

[0038] Furthermore, the limiting bracket 230 includes two limiting blocks 233, and the side of the limiting block 233 near the trapezoidal support block 232 is a blocking surface 234 perpendicular to the horizontal plane. This arrangement can prevent the hopper 100 from vibrating and causing the rotating shaft 120 to disengage from the limiting engagement with the limiting support inclined surface 231, thus blocking and restricting the rotating shaft 120.

[0039] like Figure 10 , Figure 11 As shown, the hopper trolley 300 includes a trolley body, and second support arms 310 are formed on the upper ends of both sides of the trolley body. The second support arms 310 are used to support the bearing seats 130 on both sides of the hopper body.

[0040] Furthermore, the bearing housing 130 has a flat bottom, and the second support arm 310 has a supporting flat surface at its upper end. For example... Figure 12 As shown, a bearing housing mounting bracket 311 is fixed to the upper end of the second support arm 310, and the upper end of the bearing housing mounting bracket 311 forms a support plane for supporting the bearing housing 130. Furthermore, the bearing housing 130 and the bearing housing mounting bracket 311 are fixedly connected by threaded fasteners. This connection is more stable and prevents the hopper from falling off the hopper trolley during transport.

[0041] Furthermore, such as Figure 12As shown, a flip positioning bracket 122 is fixed on one or two rotating shafts 120. Each end of the flip positioning bracket 122 has a positioning slot 123. The second support arm 310 has a corresponding through positioning pin hole 312. When the positioning pin hole 312 is opposite to the two positioning slots 123, the sealing valve 110 is positioned upwards and downwards respectively. A flip positioning pin 400 is provided to pass through the positioning pin hole 312 and insert into the positioning slot 123. In this embodiment, specifically, a flip positioning bracket 122 is provided on one side of the rotating shaft 120. The flip positioning bracket 122 is fixedly connected to the rotating shaft 120, forming a linkage to achieve positioning of the hopper at two flipped positions.

[0042] The usage process in this embodiment is as follows: The hopper bearing seat is fixed to the hopper trolley 300 with bolts. Rotating the hopper 100 allows the hopper 100's sealing valve 110 to be either at the bottom or the top. When the sealing valve 110 is at the top, it can be used for hopper feeding; when the sealing valve is facing down, it can be used for lifting to feed other equipment. The trolley has a flipping positioning pin 400. After the hopper is flipped into position, it is fixed with the flipping positioning pin 400 to prevent rotation. When the hopper 100 needs to be fed to the equipment by the lifting equipment, first flip the hopper 100 on the hopper trolley 300 until the sealing valve faces down, then push the hopper into the lifting fork 210 of the lifting equipment, loosen the bearing seat bolts fixed to the hopper trolley, lift the fork, and let the hexagonal mating shaft on the hopper enter the limiting seat 230 on the lifting fork 210. This will fix the hopper 100 on the lifting fork 210 and prevent it from flipping. The lifting equipment can then lift the hopper 100 to feed the equipment.

[0043] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
