Description

Technical Field

[0001] This utility model relates to the technical field of fruit washing equipment, and in particular to a drum-type washing machine. Background Technology

[0002] In the process of making candied fruit, the harvested fruits, such as plums and olives, need to be washed to remove sand, and this requires multiple washing processes. Therefore, a drum-type washing machine is needed to clean the fruits. A drum-type washing machine is a highly efficient cleaning device commonly used in industrial production and agricultural product processing. It removes surface dirt by rotating the drum, causing the materials to tumble and rub against each other, combined with spraying or soaking.

[0003] A search revealed Chinese patent publication number CN212035889U, which discloses a drum-type fruit washing machine. It includes a water tank with a rotating shaft at its upper end. Two gears are mounted on the shaft, and a motor is fixedly connected to one end of the shaft. The motor is fixed to the side wall of the water tank. The upper ends of the gears are rotatably connected to a drum. The drum and gears have gear teeth at their rotatable connection. The drum contains spiral blades, and both ends of the drum have end caps. Multiple connecting rods are located between the two end caps, and brushes are mounted on the connecting rods. A support plate is fixed to one side of the water tank, and a vertical plate supports a feed hopper. A discharge hopper is located at the other end of the water tank, below which is a sieve plate, and below that is a filter tank. Both the water tank and the filter tank have drain pipes. This drum-type fruit washing machine is suitable for washing most fruits without requiring adjustments to the washing mechanism for different fruits. Furthermore, the water tank has partitions, allowing for batch water changes, thus achieving water conservation.

[0004] In the aforementioned utility model, multiple connecting rods are provided on the end caps at both ends of the roller, and brushes are provided on the connecting rods. While the roller rotates, the brushes are used to clean the fruit. However, in actual use, the brushes cannot be installed or disassembled. After long-term use, the damaged brushes cannot be maintained or replaced, thus affecting the cleaning of the fruit. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a drum-type washing machine, which aims to improve the problem that damaged brushes after prolonged use can affect fruit washing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drum-type cleaning machine, comprising a workbench, a feed pipe fixedly connected to the upper surface of the workbench, a drum body disposed on the outer wall of the feed pipe, a discharge hopper disposed on the outer wall of the drum body, a hollow block disposed inside the drum body, a trapezoidal block slidably connected inside the hollow block, a tension spring fixedly connected to the outer wall of the trapezoidal block, the outer wall of the tension spring fixedly connected to the inner wall of the hollow block, a U-shaped frame rotatably connected inside the trapezoidal block, a slide block rotatably connected to the outer wall of the U-shaped frame, a slide rail slidably connected to the inner wall of the slide block, the lower surface of the slide rail fixedly connected to the inner bottom wall of the hollow block, a limit rod fixedly connected to the outer wall of the slide block, the outer wall of the limit rod penetrating the interior of the hollow block and slidably connected to the interior of the drum body, bristles fixedly connected to the outer wall of the hollow block, and a drive assembly disposed on the outer wall of the workbench.

[0007] The above technical solution involves creating multiple grooves inside the roller body that correspond to hollow blocks. After the hollow blocks are installed inside the roller body, the rotation of the roller body causes the hollow blocks and brush bristles to rotate simultaneously, cleaning the fruit inside the roller body. The brush bristles remove sand and dirt from the surface of the fruit and also remove leaves. Once leaves become trapped in the brush bristles, the hollow blocks can be disassembled to facilitate cleaning of the leaves trapped in the brush bristles. This method provides efficient cleaning of the fruit and facilitates the maintenance of the brush bristles.

[0008] As a further description of the above technical solution:

[0009] The drive assembly includes a motor, the outer wall of which is fixedly connected to the outer wall of the worktable. The output end of the motor passes through the interior of the worktable and is fixedly provided with a gear. The tooth ends of the gear are meshed with a gear ring, and the interior of the gear ring is fixedly connected to the outer wall of the roller body.

[0010] The above technical solution utilizes a motor to drive a gear to rotate, which in turn drives a gear ring to rotate, thereby causing the drum body to rotate. This causes the fruit to continuously tumble, collide, and rub against each other inside the drum body.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the roller body is located inside the workbench, and the inner wall of the roller body is provided with spiral blades.

[0013] The above technical solution involves draining water into the workbench. As the drum body rotates, the fruit continuously changes position inside the drum body, achieving uniform washing. The spiral blades also rotate with the drum body, thus conveying the fruit.

[0014] As a further description of the above technical solution:

[0015] A water tank is fixedly connected to the outer wall of the workbench. One end of a flexible hose is installed inside the water tank, and a nozzle is installed at the other end of the flexible hose.

[0016] The above technical solution involves using a nozzle to draw water from inside the water tank through a hose, and then spraying the fruit that needs to be washed.

[0017] As a further description of the above technical solution:

[0018] A U-shaped plate is fixedly connected to the lower surface of the nozzle, and a connecting rod is fixedly connected inside the U-shaped plate.

[0019] The above technical solution achieves the effect of fixing the nozzle by means of a U-shaped plate, and the U-shaped plate moves with the connecting rod by means of the fixing between the U-shaped plate and the connecting rod.

[0020] As a further description of the above technical solution:

[0021] Both ends of the connecting rod are rotatably connected to fixed blocks, and the lower surface of the fixed blocks is fixedly connected to the upper surface of the workbench.

[0022] The above technical solution achieves the effect of fixing the fixed block by using the worktable, and limits the rotation of the connecting rod by using the inside of the fixed block.

[0023] As a further description of the above technical solution:

[0024] A hydraulic rod is fixedly connected to the upper surface of the workbench, and a transmission block is fixedly connected to the output end of the hydraulic rod. The inner wall of the transmission block is slidably connected to the upper outer wall of the workbench.

[0025] The above technical solution involves using a hydraulic rod to move the transmission block, and using the upper outer wall of the worktable to limit the movement of the transmission block.

[0026] As a further description of the above technical solution:

[0027] The transmission block is internally slidably connected to an L-shaped frame, which is internally fixedly connected to the outer wall of the connecting rod.

[0028] The above technical solution achieves the transmission effect of the L-shaped frame by moving the transmission block, and the L-shaped frame drives the connecting rod to rotate.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the cooperation between hollow blocks, trapezoidal blocks, tension springs, U-shaped frames, sliding seats, slide rails and limiting rods makes it easier for maintenance personnel to install and disassemble the bristles, facilitating maintenance and replacement. At the same time, the position and number of bristles can be flexibly adjusted, thereby enhancing the cleaning effect of removing sand and impurities from fruits.

[0031] 2. In this utility model, the angle of the nozzle is adjusted by the cooperation between the hydraulic rod, transmission block, L-shaped frame, connecting rod, fixing block and U-shaped plate, so that water is sprayed onto the fruit from different directions, realizing all-round cleaning of the fruit. At the same time, the angle of the nozzle is reasonably adjusted to enhance the cleaning efficiency of the fruit. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a drum-type cleaning machine, including a workbench 1, a feed pipe 2 fixedly connected to the upper surface of the workbench 1, a drum body 3 provided on the outer wall of the feed pipe 2, a discharge hopper 4 provided on the outer wall of the drum body 3, a hollow block 6 provided inside the drum body 3, a trapezoidal block 7 slidably connected inside the hollow block 6, a tension spring 8 fixedly connected to the outer wall of the trapezoidal block 7, the outer wall of the tension spring 8 fixedly connected to the inner wall of the hollow block 6, a U-shaped frame 9 rotatably connected inside the trapezoidal block 7, a slide block 10 rotatably connected to the outer wall of the U-shaped frame 9, a slide rail 11 slidably connected to the inner wall of the slide block 10, the lower surface of the slide rail 11 fixedly connected to the inner bottom wall of the hollow block 6, a limit rod 12 fixedly connected to the outer wall of the slide block 10, the outer wall of the limit rod 12 penetrating the interior of the hollow block 6 and slidably connected to the interior of the drum body 3, bristles 13 fixedly connected to the outer wall of the hollow block 6, and a drive assembly 5 provided on the outer wall of the workbench 1.

[0041] Specifically, the trapezoidal block 7 is stepped, and under the action of the hollow block 6, the movement of the trapezoidal block 7 is supported and offset. Short rods are set on both sides of the U-shaped frame 9 for rotating inside the trapezoidal block 7 and the slide 10. Thus, the U-shaped frame 9 transmits power to the slide 10 through the trapezoidal block 7. The fixed slide rail 11 supports and offsets the movement of the slide 10. The hollow block 6 achieves the effect of offset restriction on the movement of the limiting rod 12. The limiting rod 12 slides in and out inside the roller body 3 to limit or release the hollow block 6 and the bristles 13. Without external force pressing the trapezoidal block 7, the tension of the tension spring 8 provides support for the limiting rod 12 inside the roller body 3 through the trapezoidal block 7, the U-shaped frame 9 and the slide 10. The roller body 3 has multiple grooves that match the hollow block 6, which facilitates flexible adjustment of the number of hollow blocks 6 and bristles 13.

[0042] Reference Figure 1 and Figure 3 The drive assembly 5 includes a motor 501. The outer wall of the motor 501 is fixedly connected to the outer wall of the worktable 1. The output end of the motor 501 passes through the interior of the worktable 1 and is fixedly provided with a gear 502. The tooth end of the gear 502 is meshed with a gear ring 503. The interior of the gear ring 503 is fixedly connected to the outer wall of the roller body 3.

[0043] Specifically, the motor 501 drives the gear 502 to rotate, which in turn drives the roller body 3 to rotate via the gear ring 503. The worktable 1 is equipped with a support frame that matches the gear ring 503, thereby limiting the rotation of the roller body 3.

[0044] Reference Figure 4The outer wall of the roller body 3 is set inside the worktable 1, and the inner wall of the roller body 3 is provided with a spiral blade 14.

[0045] Specifically, as the roller body 3 rotates inside the worktable 1, it drives the water inside the worktable 1 to flow together, forming a water flow, thereby promoting the water flow to wash away the impurities on the surface of the fruit.

[0046] Reference Figure 4 and Figure 5 A water tank 15 is fixedly connected to the outer wall of the workbench 1. One end of a hose 16 is installed inside the water tank 15, and a nozzle 17 is installed at the other end of the hose 16. A U-shaped plate 18 is fixedly connected to the lower surface of the nozzle 17, and a connecting rod 19 is fixedly connected inside the U-shaped plate 18. Fixing blocks 20 are rotatably connected to both ends of the connecting rod 19, and the lower surface of the fixing blocks 20 is fixedly connected to the upper surface of the workbench 1. A hydraulic rod 21 is fixedly connected to the upper surface of the workbench 1, and a transmission block 22 is fixedly connected to the output end of the hydraulic rod 21. The inner wall of the transmission block 22 is slidably connected to the upper outer wall of the workbench 1. An L-shaped frame 23 is slidably connected inside the transmission block 22, and the inner wall of the L-shaped frame 23 is fixedly connected to the outer wall of the connecting rod 19.

[0047] Specifically, the hydraulic rod 21 is used to push or pull the transmission block 22 to move. The guide rail set on the upper surface of the workbench 1 restricts the movement of the transmission block 22. The groove opened inside the transmission block 22 is used to drive the L-shaped frame 23 to rotate around the connecting rod 19. The fixing blocks 20 at both ends of the connecting rod 19 support and restrict the rotation of the connecting rod 19, thereby driving the U-shaped plate 18 and the nozzle 17 to rotate around the connecting rod 19. The nozzle 17 sprays water onto the drum of the washing machine through the hose 16 and the water tank 15, realizing multi-angle cleaning of the fruit.

[0048] Working principle: When using this washing machine, the fruit is placed inside the feed pipe 2 and transported to the inside of the drum body 3. The motor 501 drives the gear 502, which in turn drives the gear ring 503 and the drum body 3 to rotate. A support frame is set on the rear side of the gear ring 503, and the worktable 1 fixes the support frame to limit the rotation of the gear ring 503 and the drum body 3. At the same time, a roller frame is set on the left inner wall of the worktable 1, which fits against the left outer wall of the drum body 3 to support the rotation of the drum body 3. The hydraulic rod 21 pushes the transmission block 22 to move on the outer wall of the worktable 1, which drives the L-shaped frame 23 to rotate forward, so that the connecting rod 19 rotates forward inside the fixed block 20, thereby driving the U-shaped plate 18 and the nozzle 17 to rotate. The spray angle of the nozzle 17 on the drum body 3 is adjusted to enhance the cleaning effect of the fruit.

[0049] When the drum body 3 rotates, the hollow block 6 and brush bristles 13 installed inside the drum body 3 remove sand and impurities from the fruit inside the drum body 3. Finally, as the drum body 3 and the spiral blade 14 rotate, the fruit inside the drum body 3 moves from right to left, so that the washed fruit is discharged through the discharge hopper 4. When it is necessary to disassemble the hollow block 6, the drum body 3 is kept stationary, the trapezoidal block 7 is pressed, and the tension spring 8 is stretched. The trapezoidal block 7 drives the U-shaped frame 9 to rotate backward and move to the left, thereby driving the slide block 10 to move to the left on the outer wall of the slide rail 11. This causes the limiting rod 12 to slide out of the inside of the drum body 3 and no longer limit the hollow block 6. The hollow block 6 and brush bristles 13 slide out of the inside of the drum body 3, realizing the disassembly of the hollow block 6 and brush bristles 13 for easy maintenance or replacement. Finally, the wastewater inside the workbench 1 is discharged through the discharge pipe set in the middle of the workbench 1.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
