Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 7 As shown, the present application provides a device for preparing a preservative for fresh fruits and vegetables, comprising a supporting platform 7, and also comprising: The crushing mechanism 2 is arranged on the supporting platform 7 and is used to crush the raw materials for the production of the preservative. The filtering mechanism 1 is arranged on the supporting platform 7 and is used for filtering the crushed raw materials; The recovery mechanism 3 is arranged on one side of the filtering mechanism 1 and the crushing mechanism 2, and is used to recover the uncrushed production raw materials; The striking mechanism 4 is arranged in the filtering mechanism 1 and is used to increase the filtering efficiency; The first driven mechanism 5 is connected to the filtering mechanism 1 and the recovery mechanism 3 and is used to drive the recovery mechanism 3 to work; The second driven mechanism 6 is connected to the striking mechanism 4 and is used to drive the striking mechanism 4 to work; The crushing mechanism 2 includes a crushing chamber 21; a crushing knife 24 is rotatably connected in the crushing chamber 21; a guide plate 23 is fixedly connected to the side wall of the crushing chamber 21; the guide plate 23 is provided in multiple groups; a reversing plate 231 is fixedly connected to the side wall of the crushing chamber 21 below the guide plate 23; a feed pipe 22 is fixedly connected to the top of the crushing chamber 21; During operation, in the prior art, the raw materials are crushed by a crushing component, and the filter screen is prevented from being blocked by the raw materials by a cleaning component. However, in the actual crushing process, it is found that when the raw materials enter the tank body, they fall directly to the bottom due to the inertia of falling. Even if they are crushed by the crushing component during the falling process, some of the raw materials still do not contact the crushing component, resulting in these raw materials staying at the bottom and unable to be crushed. After the crushing is completed, the uncrushed raw materials need to be taken out and crushed again, resulting in a decrease in crushing efficiency. In order to prevent such incidents from happening, firstly, the production of the preservative The raw material is poured into the crushing bin 21 through the feed pipe 22, and the raw material is crushed by the crushing knife 24. When the raw material enters the crushing bin 21, the guide plate 23 is set to make the raw material contact with the crushing knife 24 to the greatest extent, so as to avoid the raw material entering the crushing bin 21 and falling directly to the bottom. After the raw material is crushed into small particles, it reaches the filtering mechanism 1 through filtration, and the filtering mechanism 1 is used to filter the raw material. Some unqualified raw materials will be transferred to the crushing mechanism 2 again through the recovery mechanism 3 for secondary crushing until they pass the filtration and screening, and the filtering efficiency is accelerated by the striking mechanism 4 during filtration.

[0020] like Figure 3-Figure 7As shown, the filtering mechanism 1 includes a filtering bin 11; a vibration box 12 is fixedly connected to the side wall of the filtering bin 11; a vibration spring 13 is fixedly connected inside the vibration box 12; a lifting block 131 is fixedly connected to the end of the vibration spring 13 away from the vibration box 12; the lifting block 131 is slidably arranged in the vibration box 12; a vibration filter plate 26 is fixedly connected to the end of the lifting block 131 away from the vibration spring 13; the vibration filter plate 26 is arranged at the connection between the crushing bin 21 and the filtering bin 11; a movable filter plate 14 is hingedly connected to the side wall of the filtering bin 11; the movable filter plate 14 is arranged below the vibration filter plate 26; a connecting column 142 is fixedly connected to the end of the movable filter plate 14 away from the filtering bin 11; and the end of the connecting column 142 away from the movable filter plate 14 is fixedly connected to the vibration filter plate 26 ; A movable discharge plate 15 is hingedly connected to the bottom of the movable filter plate 14; the end of the movable discharge plate 15 away from the movable filter plate 14 is fixedly connected to the filter bin 11; the side wall of the filter bin 11 is fixedly connected to a fixed filter plate 16; the fixed filter plate 16 is arranged below the movable filter plate 14; the side wall of the filter bin 11 below the fixed filter plate 16 is fixedly connected to a fixed discharge plate 161; the striking mechanism 4 is arranged between the fixed filter plate 16 and the movable filter plate 14; the striking mechanism 4 includes a rotating column 41; a bottom box 42 is fixedly connected to the rotating column 41; a telescopic spring 43 is fixedly connected in the bottom box 42; a striking head 44 is fixedly connected to the end of the telescopic spring 43 away from the bottom box 42; a pulley 45 is rotatably connected to the end of the striking head 44; the pulley 45 contacts the movable filter plate 14; During operation, the raw materials will fall onto the vibrating filter plate 26 after being cut by the crushing knife 24. At this time, the raw materials are cut into small particles. However, due to contact during the cutting process, the cut particle sizes of some raw materials will be different. At the same time, the mesh number on the vibrating filter plate 26 is not the mesh number required by production, while the movable filter plate 14 and the fixed filter plate 16 in the filtering mechanism 1 are the required mesh numbers. The mesh number on the vibrating filter plate 26 is larger. After the raw materials reach the vibrating filter plate 26, they will be filtered onto the movable filter plate 14 and filtered through the movable filter plate 14. Qualified raw materials will be filtered onto the movable discharge plate 15 below and discharged through the movable discharge plate 15, while unqualified raw materials will roll onto the fixed filter plate 16 below and be filtered again through the fixed filter plate 16. At the same time, in order to speed up the filtration efficiency, the rotating column 41 in the filter bin 11 is driven to rotate while filtering. When the rotating column 41 rotates, it will drive the striking head 44 to rotate. When rotating, the striking head 44 will hit the movable filter plate 14, thereby The movable filter plate 14 is lifted, and in the process of lifting, the upper vibrating filter plate 26 is driven to be lifted through the connecting column 142. When hitting the movable filter plate 14, the raw materials on the movable filter plate 14 will become active, thereby accelerating the filtering speed of the raw materials. When the vibrating filter plate 26 is lifted, the uncrushed raw materials on the vibrating filter plate 26 are lifted, so as to contact with the crushing knife 24, and the crushing knife 24 is used to crush the raw materials again. At the same time, when the vibrating filter plate 26 is lifted, the vibration spring 13 is pulled, and the vibrating filter plate 26 is driven to shake during rebound, thereby preventing the raw materials from being stuck on the vibrating filter plate 26. When the striking head 44 strikes the movable filter plate 14, the movable filter plate 14 and the striking head 44 can be protected by the telescopic spring 43 and the pulley 45, so as to avoid hard contact between the striking head 44 and the movable filter plate 14, thereby causing damage to the movable filter plate 14. While driving the movable filter plate 14 to rise, the movable discharge plate 15 is also driven to rise.

The unfiltered raw materials will slide through the fixed discharge plate 161 to the conveyor belt below, and then be transported to the recovery pipe 35 through the conveyor belt, and then the raw materials will be lifted by the spiral blades 33, and finally transported to the crushing bin 21 again through the conveying pipe 34 for secondary crushing, until all the raw materials are crushed to a qualified particle size.

[0022] like Figure 3-Figure 5 As shown, a driving box 38 is fixedly connected to the support platform 7; the recovery column 31 is fixedly connected to the top of the driving box 38; a driving gear 36 is rotatably connected in the driving box 38; the output end of the driving gear 36 is fixedly connected to the input end of the rotating shaft 32; a limiting plate 37 is fixedly connected to the bottom of the driving box 38; a transmission rod 371 is rotatably connected to the limiting plate 37; one end of the transmission rod 371 is fixedly connected to the transmission gear 372; the transmission gear 372 is meshed with the driving gear 36; the filter bin 1 above the conveyor belt 181 1 is rotatably connected to the side wall of the filter bin 11 with an inertia shaft 19; the inertia plate 191 is fixedly connected to the inertia shaft 19; the inertia plates 191 are provided in multiple groups; the inertia shaft 19 is provided at one end of the fixed filter plate 16 away from the filter bin 11; the first driven mechanism 5 includes a gear 1 51 and a gear 2 53; a belt 1 52 is sleeved on the gear 1 51 and the gear 2 53; the gear 1 51 is rotatably connected to the side wall of the filter bin 11; the input end of the gear 1 51 is fixedly connected to the output end of the inertia shaft 19; the gear 2 53 is fixedly connected to the transmission rod 371; During operation, when the unbroken raw materials fall onto the conveyor belt, they will contact the inertia plate 191, and the inertia of the falling raw materials will drive the inertia plate 191 and the inertia shaft 19 to rotate. When the inertia shaft 19 rotates, it will drive the gear 1 51 to rotate, thereby driving the gear 2 53 to rotate through the belt 1 52, and then driving the drive gear 36 to rotate through the transmission rod 371 and the transmission gear 372, and finally driving the rotating shaft 32 in the recovery column 31 to rotate, thereby realizing the recovery of raw materials.

[0023] like Figure 3-Figure 5 As shown, the second driven mechanism 6 includes a gear 3 61 and a gear 4 62; the gear 3 61 and the gear 4 62 are sleeved with a belt 2 63; the gear 3 61 and the gear 4 62 are rotatably connected to the side wall of the filter bin 11; the output end of the gear 4 62 is fixedly connected to the input end of the striking column; the input end of the gear 3 61 is fixedly connected to the output end of the feed shaft 18; During operation, the conveying shaft drives the conveying belt to rotate, and at the same time drives the gear three 61 to rotate, and then drives the gear four 62 to rotate through the belt two 63, and finally drives the striking column to rotate to achieve the striking effect.

[0024] like Figure 2As shown, the side wall of the filter bin 11 is provided with a discharge port 111; the discharge port 111 is provided in two groups; the side wall of the filter bin 11 is fixedly connected with a baffle plate 141; the baffle plate 141 is provided in two groups; the baffle plate 141 is provided above the movable filter plate 14; the side wall of the filter bin 11 below the fixed discharge plate 161 is fixedly connected with a baffle plate 2 17; During operation, qualified raw materials can be received through the discharge port 111. At the same time, when the striking column strikes the movable filter plate 14, the raw materials on the movable filter plate 14 will be bounced up. During the bouncing process, the raw materials will contact with the baffle 141 and fall on the baffle 141. Through the angle set by the baffle 141, the raw materials can slide to the middle of the movable filter plate 14 to be filtered again. At the same time, through the setting of the baffle 2 17, the raw materials can be blocked when they slide from the fixed filter plate 16 to the conveyor belt to prevent the raw materials from spilling.

[0025] like Figure 2 As shown, a crushing motor 25 is fixedly connected to the top of the crushing bin 21; the crushing knife 24 is driven to rotate by the crushing motor 25; a feeding motor 182 is fixedly connected to the side wall of the filter bin 11; and the feeding shaft 18 is driven to rotate by the feeding motor 182; During operation, the crushing motor 25 drives the crushing knife 24 to rotate, thereby achieving the crushing of the raw materials, and the feeding motor 182 drives the feeding shaft 18 to rotate, thereby driving the feeding belt 181 and the striking head 44 to rotate.

[0026] See also Figure 1-Figure 7 As shown, the present application provides a method for preparing a preservative for fresh fruits and vegetables, comprising the following steps: S1, first, pour the preservative raw material from the feed pipe 22 into the crushing bin 21, then drive the crushing knife 24 to rotate, crush the raw material, and filter the raw material from the vibrating filter plate 26 after processing. The filtered raw material will fall onto the movable filter plate 14, and the qualified raw material will be filtered by the movable filter plate 14 to the movable discharge plate 15 below, and the unqualified raw material will pass through the fixed filter plate 16 again to the conveyor belt 181, and then be transported to the recovery mechanism 3 for recovery; S2, when the raw material reaches the recovery column 31 through the recovery pipe 35, it will be transferred to the feed pipe 34 by the spiral blade 33, and enter the crushing chamber 21 again for secondary crushing. At the same time, the guide plate 23 in the crushing chamber 21 can guide the raw material so that the raw material can better contact with the crushing knife 24 when falling into the crushing chamber; S3, during crushing, part of the raw materials may not be crushed and reach the vibrating filter plate 26. At this time, the driving column 41 rotates, and the striking head 44 strikes the movable filter plate 14 and the vibrating filter plate 26, so that the characteristics of the vibration spring 13 drive the raw materials on the vibrating filter plate 26 to jump up, thereby driving the raw materials to contact the crushing knife 24 again for crushing; During operation, first, the preservative raw material is poured from the feed pipe 22 into the crushing bin 21, and then the crushing knife 24 is driven to rotate to crush the raw material. After processing, the raw material is filtered from the vibrating filter plate 26, and the filtered raw material will fall onto the movable filter plate 14. The qualified raw material will be filtered by the movable filter plate 14 to the movable discharge plate 15 below, and the unqualified raw material will pass through the fixed filter plate 16 again to the conveyor belt 181, and then be transported to the recovery mechanism 3 for recovery. When the raw material reaches the recovery column 31 through the recovery pipe 35, it will be collected by the spiral blades. The sheet 33 is transmitted to the feed pipe 34 and enters the crushing chamber 21 again for secondary crushing. At the same time, the guide plate 23 in the crushing chamber 21 can guide the raw materials so that the raw materials can better contact with the crushing knife 24 when falling in. During crushing, part of the raw materials may not be crushed and reach the vibrating filter plate 26. At this time, the driving column 41 is driven to rotate, and the striking head 44 is used to strike the movable filter plate 14 and the vibrating filter plate 26, so that the characteristics of the vibration spring 13 are used to drive the raw materials on the vibrating filter plate 26 to jump up, thereby driving the raw materials to contact with the crushing knife 24 again for crushing.

[0027] Working principle of the present invention: after being cut by the crushing knife 24, the raw material will fall onto the vibrating filter plate 26. At this time, the raw material is cut into small particles. However, due to contact during the cutting process, the particle sizes of some raw materials will be different. At the same time, the mesh number on the vibrating filter plate 26 is not the mesh number required by production, while the movable filter plate 14 and the fixed filter plate 16 in the filtering mechanism 1 are the required mesh numbers. The mesh number on the vibrating filter plate 26 is larger. After the raw material reaches the vibrating filter plate 26, it will be filtered onto the movable filter plate 14 and filtered through the movable filter plate 14. Qualified raw materials will be filtered onto the movable discharge plate 15 below and discharged through the movable discharge plate 15, while unqualified raw materials will roll onto the fixed filter plate 16 below and be filtered again through the fixed filter plate 16. At the same time, in order to speed up the filtering efficiency, the rotating column 41 in the filter bin 11 is driven to rotate while filtering. When the rotating column 41 rotates, it will drive the striking head 44 to rotate. When rotating, the striking head 44 will hit the movable filter plate 14. Thereby, the movable filter plate 14 is lifted, and in the process of lifting, the upper vibrating filter plate 26 is driven to be lifted through the connecting column 142, and when hitting the movable filter plate 14, the raw materials on the movable filter plate 14 are activated, thereby accelerating the filtering speed of the raw materials, and when the vibrating filter plate 26 is lifted, the uncrushed raw materials on the vibrating filter plate 26 are lifted, so as to contact with the crushing knife 24, and the raw materials are crushed again by the crushing knife 24, and at the same time, when the vibrating filter plate 26 is lifted, the vibration spring 13 is pulled, and the vibrating filter plate 26 is driven to shake during rebound, thereby preventing the raw materials from being stuck on the vibrating filter plate 26, and when the striking head 44 strikes the movable filter plate 14, the movable filter plate 14 and the striking head 44 can be protected by the telescopic spring 43 and the pulley 45, so as to avoid hard contact between the striking head 44 and the movable filter plate 14, thereby causing damage to the movable filter plate 14, and while driving the movable filter plate 14 to rise, the movable discharge plate 15 is also driven to rise.

[0028] Among them, the raw materials filtered by the fixed filter plate 16 will reach the fixed discharge plate 161, and then be discharged from the fixed discharge plate 161. The unfiltered raw materials will slide through the fixed discharge plate 161 to the conveyor belt below, and then be transported to the recovery pipe 35 through the conveyor belt, and then the raw materials will be lifted by the spiral blades 33, and finally transported to the crushing bin 21 again through the conveying pipe 34 for secondary crushing, until all the raw materials are crushed to a qualified particle size.

[0029] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
