Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, and in particular, to a side-plate accumulation buffer hopper and a material transfer device. Background Technology

[0002] Funnels are common material transfer devices in industrial production, widely used in metallurgy, coal, transportation, power, building materials, chemical, light industry, food, and machinery industries. In intelligent batching and mixing machines, the precise proportioning and mixing of materials are crucial, and the head funnel, as the primary contact point for materials entering the equipment, directly affects the processing effect of subsequent materials.

[0003] like Figure 1 As shown, the feeding hopper commonly used in existing technologies for transferring materials with high hardness and large particle size generally consists of a hopper body, a redirecting roller, and a hopper cover. The material falls downward from the redirecting roller in a parabolic trajectory. To prevent strong impact from falling directly onto the transfer device below, a buffer step or buffer side plate is usually provided to absorb some of the impact. The buffer step can store some material, which will slide along the stored material when falling, preventing damage to the hopper body. However, setting only one step is not enough to protect multiple points on the impact side wall end face of the entire material receiving device. The hopper has poor wear resistance and requires frequent replacement. Furthermore, this method is not suitable for materials with high viscosity and small particle size. For equipment such as ore mixing carts that need to mix different types of ore, the accumulated material needs to be cleaned after each batch, which is inconvenient to use.

[0004] In view of this, it is necessary to propose a side-plate accumulation buffer hopper and material transfer device to solve or at least alleviate some of the above-mentioned defects and improve the wear resistance and ease of use of the hopper. Utility Model Content

[0005] The side-plate accumulation buffer hopper and material transfer device provided by this utility model solve the technical problem that the impact surface of the existing hopper body is easily damaged by impact.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A side-plate accumulation buffer hopper includes a hopper body with a side feed inlet and a bottom discharge outlet. An accumulation buffer groove is arranged on the impact sidewall of the hopper body opposite to the side feed inlet, and multiple accumulation buffer grooves are arranged at intervals on the impact sidewall.

[0008] Furthermore, the side plate accumulation buffer hopper also includes an accumulation buffer platform disposed on the impact side wall, the accumulation buffer platform being arranged protruding from the impact side wall and enclosing the impact side wall to form an L-shaped opening accumulation buffer groove.

[0009] Furthermore, the material accumulation buffer platform includes a buffer plate and a positioning drive component. The buffer plate is located on the inner side of the impact side wall and forms a material accumulation buffer groove with the impact side wall. The connecting end of the buffer plate is hinged. The positioning drive component drives the buffer plate to swing around the hinge axis and position it.

[0010] Furthermore, the impact sidewall is provided with plate insertion holes extending along its width direction. The side plate accumulation buffer hopper also includes a side plate shell, which is fixedly mounted on the outer wall of the impact sidewall. The plate insertion holes are arranged through the impact sidewall and the side plate shell. The accumulation buffer platform includes an accumulation plate and a positioning mechanism. The accumulation plate, positioning mechanism and plate insertion holes are arranged in a one-to-one correspondence. The accumulation plate is inserted from the outside of the side plate shell, passes through the plate insertion holes and extends into the hopper body. The inner end of the accumulation plate and the impact sidewall form an accumulation buffer groove. The accumulation plate is movably set relative to the impact sidewall. The positioning mechanism fixes the accumulation buffer platform on the impact sidewall.

[0011] Furthermore, there is a movable gap between the material accumulation plate and the top surface of the corresponding plate insertion hole, the material accumulation plate is movably set relative to the material impact side wall along the insertion direction, and / or the material accumulation plate is swayable relative to the material impact side wall in the height direction.

[0012] Furthermore, the positioning mechanism includes a support rib, a support base plate, and fastening bolts. The support rib is fixedly mounted on the outer wall of the side plate shell. Multiple support ribs are spaced apart along the width direction of the side wall impacted by the material. The support base plate is fixedly mounted on the support rib and is arranged corresponding to the plate insertion hole. The extended end of the material accumulation plate is mounted on the support base plate and fixedly connected to the support base plate by fastening bolts.

[0013] Furthermore, the positioning mechanism also includes a positioning block and a positioning bolt. The first end of the positioning block is inserted into the movable gap between the material accumulation plate and the corresponding plate insertion hole, and the second end of the positioning block is fixedly connected to the side plate shell through the positioning bolt.

[0014] Furthermore, the positioning block has an L-shaped shape.

[0015] Furthermore, a protective lining plate is attached to the inner wall surface of the impact sidewall.

[0016] This utility model also provides a material transfer device, including a conveyor and the above-mentioned side plate accumulation buffer hopper, wherein the output end of the side plate accumulation buffer hopper extends into the lateral feed inlet, and the output end of the side wall impacted by the material is located above the accumulation buffer trough.

[0017] This utility model has the following beneficial effects:

[0018] This utility model discloses a side-plate accumulating buffer hopper and a material transfer device, comprising a hopper body with a lateral feed inlet and a bottom discharge outlet. Accumulating buffer troughs are arranged on the impact-receiving sidewall of the hopper body opposite the lateral feed inlet, and these troughs are interconnected with the bottom outlet. Multiple accumulating buffer troughs are spaced apart on the impact-receiving sidewall. When material is guided through the side-plate accumulating buffer hopper, as the material moves from the lateral feed inlet to the bottom discharge outlet and is discharged, the initial material accumulates and stores in each accumulating buffer trough. Subsequent material entering collides with the stored material and is discharged from the bottom discharge outlet, avoiding direct impact contact between the material and the impact-receiving sidewall as in the prior art, thus extending the service life of the hopper body.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0034] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 The present invention provides a side plate accumulation buffer hopper, including a hopper body 10, the hopper body 10 having a side feed inlet 101 and a bottom discharge outlet 102, and a material accumulation buffer groove 103 arranged on the material impact side wall 11 opposite to the side feed inlet 101 of the hopper body 10. Multiple material accumulation buffer grooves 103 are arranged at intervals on the material impact side wall 11.

[0035] This utility model provides a side-plate accumulation buffer hopper, including a hopper body 10. The hopper body 10 has a side feed inlet 101 and a bottom discharge outlet 102. The material receiving impact sidewall 11 opposite to the side feed inlet 101 of the hopper body 10 is provided with accumulation buffer grooves 103. The accumulation buffer grooves 103 are interconnected with the bottom outlet. Multiple accumulation buffer grooves 103 are arranged at intervals on the material receiving impact sidewall 11. When the material is guided through the side-plate accumulation buffer hopper, during the process of the material being transferred from the side feed inlet 101 to the bottom discharge outlet 102 and discharged, the initial material will be accumulated and stored in each accumulation buffer groove 103. When the subsequent material enters, it collides with the stored material and is discharged from the bottom discharge outlet 102. This avoids the direct impact contact between the material and the material receiving impact sidewall surface in the prior art, and extends the service life of the hopper body 10.

[0036] Understandably, in this invention, the material accumulation buffer trough 103 is interconnected with the bottom outlet; the funnel body 10 can be an isosceles trapezoidal funnel or a right-angled trapezoidal funnel. Optionally, the number of material accumulation buffer troughs 103 can be two, three, four, or other numbers, arranged according to the actual situation. More preferably, the multiple material accumulation buffer troughs 103 are evenly spaced along the height direction.

[0037] Furthermore, the side-plate accumulation buffer hopper also includes an accumulation buffer platform 20 disposed on the material impact sidewall 11. The accumulation buffer platform 20 protrudes from the material impact sidewall 11 and is arranged to enclose the material impact sidewall 11 to form an accumulation buffer groove 103 with an upper opening (L-shaped opening). It can be understood that if it is a right-angled trapezoidal funnel, the lateral feed inlet 101 is disposed on the upper part of the funnel body 10 and on the hypotenuse, and the right-angled side (vertical extension side) is the material impact sidewall 11.

[0038] Please refer to this again. Figure 2In an optional embodiment of this utility model, the material accumulation buffer platform 20 includes a buffer plate 21 and a positioning drive member 22. The buffer plate 21 is disposed on the inner side of the material impact side wall 11 and surrounds the material impact side wall 11 to form a material accumulation buffer groove 103. The connecting end of the buffer plate 21 is hinged. The buffer plate 21 is driven to swing around the hinge axis and be positioned by the positioning drive member 22. Specifically, the buffer plate 21 is horizontally arranged on the inner side of the impact side wall 11 via the positioning drive component 22. The buffer plate 21 is hinged to the impact side wall 11. The positioning drive component 22 is located at the lower part of the buffer plate 21. The positioning drive component 22 is a telescopic rod. One end of the telescopic rod is hinged to the impact side wall 11, and the other end is hinged to a sliding block. The sliding block is movably located at the bottom of the buffer plate 21 along the extension direction of the buffer plate 21. Ultimately, the telescopic rod drives the buffer plate 21 to swing and position around the hinge axis through its telescopic movement. When working, the telescopic rod drives the buffer plate 21 to be arranged horizontally. When not working or when unloading is required, the telescopic rod drives the buffer plate 21 to be arranged downwardly.

Figure 3 In an optional embodiment of this utility model, a plate insertion hole 111 extending along its width direction is provided on the material impact sidewall 11. The side plate accumulation buffer hopper also includes a side plate shell 30, which is disposed on the outer wall surface of the material impact sidewall 11. The plate insertion hole 111 is arranged through the material impact sidewall 11 and the side plate shell 30. The material accumulation buffer platform 20 includes a material accumulation plate 23 and a positioning mechanism 24. The material accumulation plate 23 and the positioning mechanism 24 are arranged in a one-to-one correspondence with the plate insertion hole 111. The material accumulation plate 23 is inserted from the outside of the side plate shell 30 through the plate insertion hole 111 and extends into the funnel body. The inner end of the material accumulation plate 23 and the material impact sidewall 11 enclose each other to form a material accumulation buffer groove 103. The material accumulation plate 23 is movably arranged relative to the material impact sidewall 11. The material accumulation buffer platform 20 is fixedly arranged on the material impact sidewall 11 by the positioning mechanism 24. Optionally, during operation, the material accumulation plate 23 is horizontally arranged on the side plate housing 30 and / or the material impact side wall 11 via the positioning mechanism 24. When not in operation or when unloading is required, the positioning structure is adjusted to pull the material accumulation plate 23 outward and / or tilt it downward. Optionally, the side plate housing 30 is connected to the material impact side wall 11 by a connecting flange.

[0040] In this embodiment of the present invention, the material accumulation buffer platform 20 on the inner side of the material impact sidewall 11 forms a material accumulation buffer trough 103, which can temporarily store a portion of the material in the material accumulation buffer trough 103. The falling material will collide with the stored material, avoiding direct contact with the liner plate, thus extending the service life of the funnel body. Furthermore, the material accumulation plate 23 is movable relative to the material impact sidewall 11. In actual production, the material accumulation plate 23 can be tilted to different tilt angles according to the material discharge situation on site to achieve material discharge.

[0041] Please refer to this again. Figure 4 , Figure 5 , Figure 6 and Figure 7 Furthermore, a movable gap is left between the material accumulation plate 23 and the top surface of the corresponding plate insertion hole 111. The material accumulation plate 23 is movably arranged relative to the material impact side wall 11 along the insertion direction, and / or the material accumulation plate 23 is swayable relative to the material impact side wall 11 in the height direction. Optionally, after being constrained by the contact positioning mechanism 24, the material accumulation plate 23 can be pulled out or swung up and down.

[0042] Furthermore, the positioning mechanism 24 includes a supporting rib plate 241, a supporting base plate 242, and fastening bolts 243. The supporting rib plate 241 is fixedly mounted on the outer wall surface of the side plate housing 30. Multiple supporting rib plates 241 are arranged at intervals along the width direction of the material impact side wall 11. The supporting base plate 242 is fixedly mounted on the supporting rib plate 241 and is arranged corresponding to the plate insertion hole. The extended end of the material accumulation plate 23 is mounted on the supporting base plate 242 and fixedly connected to the supporting base plate 242 by the fastening bolts 243. Optionally, the straight rib plate is a right triangle plate, with one right-angled side of the supporting rib plate welded on the side plate housing 30, and the supporting base plate 242 welded to the other right-angled top surface of the supporting rib plate 241.

[0043] Optionally, the material accumulation plate 23 is provided with fastening holes, and the fastening bolts 243 pass through the fastening holes and the support base plate 242 and then engage with the fastening nuts. In order to facilitate the adjustment of the tilt angle to accommodate different materials, multiple rows of fastening holes are arranged at intervals along the extension direction of the material accumulation plate 23.

[0044] Furthermore, the positioning mechanism 24 also includes a positioning block 244 and a positioning bolt 245. The first end of the positioning block 244 is inserted into the movable gap between the material accumulation plate 23 and the corresponding plate insertion hole 111, and the second end of the positioning block 244 is fixedly connected to the side plate housing 30 by the positioning bolt 245. It can be understood that the material accumulation plate 23 is supported at the bottom of the outer end of the material accumulation plate 23 by the supporting base plate 242 and fixed by the fastening bolt 243; the positioning block 244 clamps the material accumulation plate 23 from the top near the outer end of the material accumulation plate 23, thereby achieving stable installation and detachable and movable arrangement of the material accumulation plate 23.

[0045] Furthermore, the positioning block 244 has an L-shaped shape.

[0046] Furthermore, in order to further improve the service life of the funnel body, a protective liner is attached to the inner wall surface of the material impact side wall 11.

[0047] Furthermore, wear-resistant square steel is welded to the ends of the material accumulation plate 23 to prevent end wear.
