Description

Technical Field

[0001] This specification relates to the field of high-efficiency raisin crushing technology, specifically a high-efficiency raisin crusher. Background Technology

[0002] During the production and processing of raisins, it is necessary to break up the clumps. The traditional method of breaking them up is to use a crusher. However, crushers can only handle small clumps. If the clumps are large, the crusher will not break them up completely and will damage the raisins too much, affecting subsequent production. Raisins are prone to clumping during the production process, so it is necessary to break large clumps of raisins into smaller pieces.

[0003] However, existing raisin crushers have shortcomings in their crushing structure. They generally adopt single-stage crushing, which easily leads to low crushing efficiency, uneven crushing, and inability to thoroughly crush raisins, affecting the crushing efficiency. At the same time, crushed raisins are prone to remain at the bottom of the device after processing, which can cause problems with material discharge, reducing the practicality of the device and the stability of the crushing device needs to be improved. Therefore, there is an urgent need for a high-efficiency raisin crusher to solve the above problems.

[0026] Please refer to the following: Figures 1-7 ,in, Figure 1 This is a schematic diagram of the internal three-dimensional structure of a high-efficiency raisin crusher according to the present invention; Figure 2 This is a three-dimensional internal structural diagram of a high-efficiency raisin crusher according to the present invention from another angle; Figure 3 This is a three-dimensional structural diagram of the right side of a high-efficiency raisin crusher according to the present invention;

[0028] A high-efficiency raisin crusher includes: a base plate 1, support legs 2, and a crushing box 3. Support legs 2 are fixedly mounted on the top of the base plate 1, and are located at the four corners of the base plate 1. The crushing box 3 is fixedly mounted on the top of the support legs 2. A crushing motor 7 is detachably mounted on the left side of the base plate 1. A rotating shaft 8 is movably connected to the output end of the crushing motor 7. A first crushing shaft 9 is movably mounted on the end of the rotating shaft 8 away from the crushing motor 7. First crushing rods 10 are evenly mounted on the outer side of the first crushing shaft 9. A drive bearing 11 is sleeved on the outer side of the crushing motor 7. A belt 12 is sleeved on the outer side of the drive bearing 11. The belt 12 is located away from the drive bearing 7. A driven bearing 13 is provided at one end of the driven bearing 11. A second crushing shaft 14 is movably installed inside the driven bearing 13. A second crushing rod 15 is evenly installed on the outer side of the second crushing shaft 14. A discharge box 27 is fixedly installed at the bottom of the crushing box 3. A cylinder 28 is fixedly installed on the left side of the discharge box 27. A telescopic rod 29 is movably installed on the right side of the cylinder 28. A push plate 30 is fixedly installed on the right side of the telescopic rod 29. A discharge port 31 is fixedly installed on the right side of the discharge box 27. The discharge port 31 penetrates the right side of the crushing box 3 and extends to the outer side of the crushing box 3. A control switch 39 is fixedly installed on the front side of the crushing box 3.

[0029] When the crushing motor 7 is powered on, it drives the rotating shaft 8 to rotate, causing the first crushing rod 10 mounted on the upper side of the first crushing shaft 9 to rotate. Simultaneously, the belt 12 mounted on the rotating shaft 8 drives the driven bearing 13 to rotate, which in turn drives the second crushing rod 15 on the upper side of the second crushing shaft 14 to rotate. This results in relative movement between the first crushing rod 10 and the second crushing rod 15. This multi-stage crushing design provides high crushing efficiency, high crushing fineness, and uniform crushing, significantly improving the efficiency and quality of raisin raw material crushing, thereby enhancing work efficiency and product quality. The device consists of a cylinder 28, a telescopic rod 29, and a push plate 30. Activating the cylinder 28 causes the telescopic rod 29 to move, allowing the push plate 30 to push the raisins out of the discharge box 27. The raisins are then discharged from the discharge port 31, preventing the processed raisins from accumulating inside the box and causing blockages. This facilitates the discharge of the processed raisins, improving the device's practicality. The device is rationally designed, structurally stable, highly practical, easy to operate, provides good crushing results, and has high working efficiency.

[0030] A feed box 4 is fixedly installed on the top of the crushing box 3, and a feed inlet 5 is fixedly installed on the top of the feed box 4. A primary crushing blade 6 is movably installed inside the feed box 4, and both ends of the primary crushing blade 6 penetrate the side wall of the feed box 4.

[0031] The feeding box 4 and the crushing box 3 are fixedly connected. The feeding port 5 is installed on the top of the feeding box 4, which can easily add raw materials into the feeding box 4. The primary crushing blades 6 are used to perform primary crushing of the raisin raw materials in the feeding box 4. The woven bag raw materials after primary crushing fall into the crushing box 3, improving the crushing efficiency of the raisin raw materials.

[0032] The crushing box 3 has a filter screen opening 19 on the right side, and a filter screen plate 20 is movably installed inside the filter screen opening 19. A positioning plate 21 is fixedly installed on the left side of the inner wall of the crushing box 3. The positioning plate 21 has a groove on one side of the filter screen plate 20. The left side of the filter screen plate 20 is inserted into the interior of the positioning plate 21. A handle 22 is fixedly installed on the right side of the filter screen plate 20. The handle 22 is connected to the filter screen plate 20 by welding.

[0033] The filter opening 19 facilitates the placement of the filter plate 20. The positioning plate 21 is used to position the filter plate 20, preventing it from tilting during placement and affecting its normal use. The filter plate 20 filters the crushed raisin raw material, and small raisin particles fall onto the sieve plate 25 for sieving. The handle 22 increases the contact area between the hand and the filter plate 20, making it easy to pull the filter plate 20 out from the filter opening 19.

[0034] The inner wall of the crushing box 3 is detachably equipped with a fixing plate 16, and crushing fixing teeth 17 are evenly installed on the upper side of the fixing plate 16. The fixing plate 16 is located on the rear side of the first crushing shaft 9.

[0035] The fixed plate 16 has positioning holes at all four corners to position it. The cooperation between the fixed plate 16 and the crushing fixed teeth 17 can assist in crushing the raisins when the first crushing shaft 9 and the first crushing rod 10 are crushing them, thereby improving the crushing efficiency of the raisin raw materials.

[0036] The inner wall of the crushing box 3 is fixedly installed with first inclined plates 18 on the left and right sides. The upper side of the first inclined plates 18 is threaded with positioning screws. The first inclined plates 18 are located directly below the crushing device.

[0037] The first inclined plate 18 has a positioning hole on its upper opening, which facilitates the installation of the positioning screw. At the same time, it can assist the raisin crushing equipment in fully crushing the raisins, saving operation steps, improving the efficiency of raisin crushing, and ensuring that the raw materials are fully crushed.

[0038] The crushing box 3 is fixedly installed with bearing plates 23 on the left and right sides. Screening pumps 24 are evenly installed on the upper side of the bearing plates 23. Screening screen plate 25 is fixedly installed on the top of the screening pump 24. The screening screen plate 25 is located directly below the filter screen plate 20.

[0039] The bearing plate 23 is fixedly installed on both sides of the inner wall of the crushing box 3, which serves to support the screening pump 24. With the cooperation of the screening pump 24 and the screening screen plate 25, the raisins can be screened, leaving the unqualified raisins above the screening screen plate 25, and the qualified raisins fall to the bottom and are discharged and collected, resulting in a good screening effect.

[0040] A second inclined plate 26 is fixedly installed inside the crushing box 3, and the second inclined plate 26 is located directly below the screen plate 25;

[0041] The second inclined plate 26 allows the raisins that have been screened on the upper side of the sieve plate 25 to fall directly into the discharge box 27, thus avoiding waste of raisins.

[0042] The crushing box 3 has uniformly spaced heat dissipation slots 32 on its left side, which are located on the left side of the cylinder 28. A dustproof mesh plate 40 is detachably installed on the outside of the crushing box 3, which is located outside the heat dissipation slots 32.

[0043] The heat dissipation slot 32 serves to dissipate the heat generated when the cylinder 28 is started, preventing the equipment from malfunctioning due to excessive temperature. The dustproof mesh plate 40 also serves to prevent dust from entering the crushing box 3 through the heat dissipation slot 32, thus avoiding the normal operation of the equipment inside the crushing box 3.

[0044] A placement plate 33 is fixedly installed on the right side of the crushing box 3. A water storage tank 34 is detachably installed on the upper side of the placement plate 33. A water supply pipe 35 is connected to the front side of the water storage tank 34. A water pump 36 is fixedly installed at the end of the water supply pipe 35 away from the water storage tank 34. A drain pipe 37 is fixedly installed on the top of the water pump 36. The drain pipe 37 passes through the top of the crushing box 3 and extends into the interior of the crushing box 3. A water spray plate 38 is fixedly installed at the end of the drain pipe 37 away from the water pump 36. Water spray nozzles are evenly opened on the upper side of the water spray plate 38.

[0045] The water storage tank 34 is supported by the placement plate 33. The combination of the water storage tank 34, water supply pipe 35, water pump 36 and drain pipe 37 can spray the dust generated during crushing inside the crushing box 3, reducing the dust inhaled by workers and the damage to the environment, thus improving the dust removal effect. In this invention, water can be sprayed into the inner cavity of the crushing box 3. The dust adheres to the water droplets, which can reduce the movement of dust to the outside of the crushing box 3, thus improving the dust reduction effect.

[0046] In summary, the high-efficiency raisin crusher provided in this specification, during operation, firstly checks the components used in the equipment and installs them sequentially. Raisin raw materials are added to the inside of the feed box 4 through the feed inlet 5. The primary crushing blades 6 perform primary crushing of the raisin raw materials in the feed box 4. The woven bag raw materials after primary crushing fall into the crushing chamber 3, improving the crushing efficiency of the raisin raw materials. Then, the raisins inside the feed box 4 fall directly into the crushing chamber 3. After the crushing motor 7 is powered on, it drives the rotating shaft 8 to rotate, thereby rotating the first crushing rod 10 installed on the upper side of the first crushing shaft 9. Simultaneously, the belt 12 installed on the rotating shaft 8 drives the... The rotating bearing 13 drives the driven bearing 13 to rotate the second crushing rod 15 on the upper side of the second crushing shaft 14 via the belt 12, thereby causing the first crushing rod 10 and the second crushing rod 15 to move relative to each other. This multi-stage crushing design results in high crushing efficiency, high crushing fineness, and uniform crushing, significantly improving the efficiency and quality of raisin raw material crushing, thus increasing work efficiency and product quality. The first inclined plate 18 assists the raisin crushing equipment in fully crushing the raisins, saving operation steps and improving crushing efficiency. Finally, the filter screen 20 filters the crushed raisin raw material. Small raisin granules fall onto the sieve screen 25 for screening. The handle 22 increases the contact area between the hand and the filter screen 20, making it easier to pull the filter screen 20 out of the filter opening 19 for cleaning. When dust suppression is needed inside the crushing chamber 3, the combination of a water tank 34, water pipe 35, water pump 36, and drain pipe 37 sprays away dust generated during crushing, reducing dust inhalation by workers and environmental damage, resulting in better dust removal. In this invention, water can be sprayed into the inner cavity of the crushing chamber 3; dust adheres to the water droplets, reducing dust dispersion to the outside of the crushing chamber 3. The device features a pneumatic cylinder 28, a telescopic rod 29, and a pusher plate 30. Activating the cylinder 28 drives the telescopic rod 29 to perform all movements, allowing the pusher plate 30 to push the raisins out of the discharge box 27. Finally, the raisins in the discharge box 27 are discharged from the discharge port 31, preventing the processed raisins from accumulating inside the discharge box 27 and causing blockages. This facilitates the discharge of processed raisins, improving the device's practicality. The device is rationally designed, structurally stable, highly practical, easy to operate, provides good crushing effect, and has high working efficiency.
