Description

Adjustable brush gap structure Technical Field

[0001] This application relates to the field of cleaning equipment technology, for example to a structure with adjustable brush gap. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] Traditional double-row brush cleaning equipment typically employs a fixed-gap design, where the distance between the upper and lower brush rollers is a fixed, non-adjustable value. In practical applications, due to significant differences in the diameter of various materials (such as fruits, vegetables, medicinal herbs, or industrial parts), users need to customize cleaning equipment with appropriate gaps based on the size of the materials to be cleaned. For example, a larger gap cleaning machine is required for large-diameter materials, while a smaller gap machine is needed for small-diameter materials. This design has significant drawbacks: firstly, users need to purchase multiple dedicated machines for different material sizes, leading to a substantial increase in procurement costs; secondly, a single machine can only accommodate materials of a specific size, resulting in low equipment utilization and insufficient production flexibility. Summary of the Invention

[0004] This application provides an adjustable brush gap structure. Through the cooperation of screw and nut, the gap distance between the upper and lower brush rollers can be flexibly adjusted within a certain range, so that a single device can adapt to the cleaning needs of various materials with different diameters (such as fruits, vegetables, and medicinal materials with significant diameter differences), eliminating the need to purchase special equipment for materials of different sizes and significantly reducing the user's procurement costs.

[0005] An adjustable brush gap structure includes: a fixed plate, a roller, a support beam, a positioning rod, a fixing ring, a screw, and a nut;

[0006] The fixing plate is provided in two and is arranged at intervals relative to each other, including a fixing vertical plate and a fixing horizontal plate;

[0007] Multiple rollers are movably arranged between two fixed plates, with rotating shafts fixedly connected to both ends of each roller.

[0008] An elongated hole, set longitudinally on the fixed vertical plate, allows the shaft to be inserted and slide up and down;

[0009] The support beam has two beams, each located on the outside of two fixed plates, and has fixed holes that allow the shaft to be inserted.

[0010] Multiple positioning rods, with both ends passing through elongated holes in the fixed plate and connected to two support beams;

[0011] A fixed ring is detachably connected to the support beam, with its middle part rotatably connected to a rotating shaft.

[0012] Multiple screws are arranged longitudinally at intervals, with both ends penetrating the support beam and the fixing cross plate;

[0013] Multiple nuts are mounted on the screw, located on both sides of the support beam and the fixed cross plate, and are used to adjust and lock the position of the screw and the support beam.

[0014] By using the screw and nut, the gap between the upper and lower brush rollers can be flexibly adjusted within a certain range, allowing a single unit to adapt to the cleaning needs of various materials with different diameters (such as fruits, vegetables, and medicinal materials with significant diameter differences). This eliminates the need to purchase special equipment for materials of different sizes, significantly reducing the user's procurement costs.

[0015] In some embodiments, the rotating shafts of adjacent rollers are interconnected and rotate synchronously.

[0016] In some embodiments, the shaft of one of the rollers is connected to a motor assembly and driven to rotate; the motor assembly is mounted on a support beam.

[0017] In some embodiments, the upper end of the screw is connected to a hand-tightening handle.

[0018] In some embodiments, three positioning rods are provided, located at both ends and the middle of the support beam, respectively.

[0034] Unless otherwise stated, the term "multiple" means two or more.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0036] As shown in Figures 1-6, this embodiment of the present disclosure provides an adjustable brush gap structure, including: a fixing plate 11, a roller 13, a support beam 14, a positioning rod 17, a fixing ring 19, a screw 15, and a nut 16;

[0037] The fixing plate 11 has two plates that are spaced apart from each other. The fixing plate 11 is formed by bending a metal plate. The upper part of the fixing vertical plate is bent to form the fixing horizontal plate, and the lower part is fixed to the frame 12.

[0038] Two rows of brush rollers are provided between the two fixed plates 11. The lower row of brush rollers does not need to be adjusted and can be fixedly installed. The upper row of brush rollers can be adjusted. Of course, depending on the actual needs, you can choose which row of brush rollers to adjust or both can be adjusted.

[0039] Multiple rollers 13 are movably arranged between two fixed plates 11, and their two ends are fixedly connected to rotating shafts 131; the rollers 13 can be brush rollers or other rotating components such as conveyor rollers.

[0040] The elongated holes 111, in number and position, correspond to the roller 13 and the positioning rod 17, and are longitudinally set on the fixed vertical plate, allowing the rotating shaft 131 to be inserted and slide up and down;

[0041] The support beam 14 has two beams, which are respectively located on the outside of the two fixed plates 11. Each beam has a fixing hole that allows the rotating shaft 131 to be inserted. The support beam 14 is an approximately C-shaped or U-shaped structure formed by bending a metal plate.

[0042] Multiple positioning rods 17, with both ends passing through elongated holes 111 on the fixed plate 11, are connected to two support beams 14. The positioning rods 17 constrain and limit the spacing and position of the two support beams 14 to ensure their synchronous lifting and lowering adjustment. The positioning rods 17 are slidably set within the elongated holes 111.

[0043] The number and position of the fixed rings 19 correspond one-to-one with the rotating shafts 131 of the roller 13, and are detachably connected to the support beam 14, with the middle part rotatably connected to the rotating shaft 131;

[0044] Multiple screws 15 are arranged longitudinally at intervals, with both ends penetrating the support beam 14 and the fixing cross plate; each support beam 14 has one screw 15 at each end.

[0045] Multiple nuts 16 are mounted on the screw 15, located on both sides of the support beam 14 and the fixed cross plate, respectively, for adjusting and locking the position of the screw 15 and the support beam 14. Each screw 15 can have four nuts 16. The figure only shows the nuts 16 on the upper part of the support beam 14 and the fixed cross plate, as the bent portion of the support beam 14 and the fixed plate 11 covers the nuts 16 on the lower side, and therefore they are not shown.

[0046] With the cooperation of screw 15 and nut 16, the gap between the upper and lower brush rollers can be flexibly adjusted within a certain range, so that a single device can be adapted to the cleaning needs of various materials with different diameters (such as fruits, vegetables, and medicinal materials with significant diameter differences), eliminating the need to purchase special equipment for materials of different sizes and significantly reducing the user's procurement costs.

[0047] In some embodiments, the rotating shafts 131 of adjacent rollers 13 are connected to each other and rotate synchronously.

[0048] In some embodiments, the rotating shaft 131 of one of the rollers 13 is connected to the motor assembly 18 and driven to rotate. The motor assembly 18 is mounted on the support beam 14. The brush roller system adopts an independent drive design. The motor assembly 18 is fixed on the support beam 14 and moves up and down synchronously with the brush roller, avoiding problems such as transmission chain misalignment and belt slack caused by height adjustment in traditional linkage drives, thus ensuring the stability and service life of the equipment.

[0049] In some embodiments, the upper end of the screw 15 is connected to a hand-tightening handle.

[0050] In some embodiments, three positioning rods 17 are provided, located at both ends and the middle of the support beam 14, respectively.

[0051] In some embodiments, the support beam 14 is provided with a connecting hole, and the connecting hole is connected to the fixing ring 19 by screws.
