Abstract
Description
Technical Field
[0001] This utility model relates to the field of jam processing technology, and in particular to a pre-processing device for jam production. Background Technology
[0002] Before mangoes can be processed into jam, they need to undergo a series of processes including selection, washing, and peeling. Washing mangoes involves rinsing the selected mangoes under running water to remove surface dust, dirt, and impurities.
[0003] Mangoes are typically cleaned using a brush roller cleaning machine. This machine uses the friction of rotating brush rollers to remove dirt and impurities from the surface of the mango. It has a relatively simple structure and can effectively remove branches, leaves, soil, and other debris from the mango's surface.
[0004] When mangoes are conveyed by the rotating rollers of a brush roller washing machine, the irregular shape of the mangoes often causes them to accumulate between the rollers due to the gaps between the rollers. This accumulation of mangoes greatly reduces the washing efficiency and damages the mango flesh, increasing costs. Therefore, a pre-processing device for jam production is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a pre-processing device for jam production, which aims to improve the problem that when mangoes are cleaned by a brush roller washing machine in the prior art, the irregular surface of the mangoes will accumulate between the brush rollers.

[0033] 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.
[0034] Reference Figures 1-3One embodiment of this utility model is a pre-processing device for jam production, which includes a trough frame 1. The trough frame 1 of the roller washing machine includes a drive motor, a limiter, a filter assembly and other structural equipment. This is prior art and does not belong to the improvement content of this application, so it will not be described in detail here. A fixed block 3 is fixedly connected to the bottom of the tray 1. A lifting assembly is installed at the bottom of the fixed block 3. The lifting assembly lifts and tilts the tray 1 through the fixed block 3 to prevent mangoes from accumulating inside the washing machine due to their irregular surface. The lifting assembly includes a telescopic leg 4, which is rotatably connected to the outside of the fixed block 3. When the telescopic leg 4 is lifted, the tray 1 rises and tilts, changing its angle. The fixed block 3 lifts the tray 1 without changing the contact area. A screw 6 is threadedly connected to the inside of the telescopic leg 4. When the screw 6 rotates, it drives the telescopic leg 4 to move up and down. A bevel gear 7 is fixedly connected to the bottom of the screw 6. The screw 6 is driven to rotate through the bevel gear 7. A fixed leg 5 is installed on the outside of the lifting assembly. The telescopic leg 4 moves up and down inside the fixed leg 5. A transmission assembly is installed on the outside of the fixed leg 5. The transmission assembly rotates the screw 6 to achieve the up and down movement of the telescopic leg 4. The transmission assembly includes a housing 11, which protects the internal transmission assembly and reduces the impact of the environment on the internal structure. The housing 11 is fixedly connected to the outside of the fixed leg 5. 1. Two fixed legs 5 are fixed to make the structure more stable. A motor 10 is fixedly connected inside the outer shell 11. A rotating shaft 9 is fixedly connected to the output end of the motor 10. Starting the motor 10 drives the rotating shaft 9 to rotate. Both ends of the rotating shaft 9 are fixedly connected to bevel gears 8. The rotating shaft 9 drives the bevel gears 8 to rotate. The bevel gears 8 mesh with the bevel gear 7. The rotating bevel gears 8 drive the bevel gears 7 to rotate, thereby rotating the screw 6 to realize the up and down movement of the telescopic leg 4, and adjusting the height of the slot frame 1. The bottom of the frame 1 is fixedly connected to a fixing block 2 14, and the bottom of the fixing block 2 14 is rotatably connected to a support leg 13. When the slot frame 1 is lifted and tilted by the telescopic leg 4, the contact surface between the slot frame 1 and the support leg 13 changes. The support leg 13 maintains the contact surface with the slot frame 1 through the rotatably connected fixing block 2 14, thereby providing effective support. The side of the support leg 13 is fixedly connected to a crossbar 12, which is fixedly connected between the support leg 13 and the fixing leg 5. The crossbar 12 connected between the support leg 13 and the fixing leg 5 makes the bottom structure more stable.
[0035] Reference Figure 1 , Figure 2 and Figure 5A water tank 26 is installed at the bottom of the trough frame 1. The water tank 26 contains existing equipment such as a filter assembly, water level detection, and limiters, which are not improvements in this application and will not be described in detail here. The water tank 26 supplies water to the inside of the trough frame 1 and filters and reuses the wastewater from cleaning. A water pump 27 is installed on the outside of the water tank 26, and a water supply pipe 28 is fixedly connected to the output end of the water pump 27. A spray pipe 24 is installed inside the trough frame 1. The water pump 27 draws liquid from the water tank 26 and supplies water to the spray pipe 24 inside the trough frame 1 through the water supply pipe 28. A nozzle 25 is installed at the bottom of the spray pipe 24, and the liquid inside the spray pipe 24 is sprayed through the nozzle 25 to clean the mangoes. A brush roller 31 is installed inside the trough frame 1. The outer side of the brush roller 31 has protrusions made of soft rubber material, which cleans the surface of the mangoes without damaging the flesh and also transports and moves the mangoes. The mangoes are further cleaned via nozzle 25. An electric heating wire 18 is installed inside the trough frame 1, and an air blower 16 is installed on the inner side of the trough frame 1. The air blower 16 is connected to an external air source (this is existing technology and will not be described in detail). The air blower 16 blows the air heated by the electric heating wire 18 onto the cleaned mangoes to dry them, reducing the impact of moist mangoes on the later jam processing ratio. A sliding plate 2 is fixedly connected to one end of the trough frame 1, through which the mangoes slide into the trough frame 1 for cleaning. A discharge plate 29 is fixedly connected to the other end of the trough frame 1, and a collection box 30 is installed at the bottom of the discharge plate 29. The cleaned and dried mangoes slide out through the discharge plate 29 and fall into the collection box 30 for collection, thus improving production efficiency.
[0036] Reference Figure 1 , Figure 2 and Figure 4A motor 15 is fixedly connected inside the slot frame 1. A turntable 17 is fixedly connected to the output end of the motor 15. Starting the motor 15 drives the turntable 17 to rotate. A fixed shaft 19 is fixedly connected to the outer side of the turntable 17. The rotating turntable 17 drives the fixed shaft 19 to rotate in a circle. A connecting rod 20 is rotatably connected to the outer side of the fixed shaft 19. A transmission rod 21 is rotatably connected to the end of the connecting rod 20. The length of the connecting rod 20 is less than the longest distance from the center point of the fixed shaft 19 to the center point of the connection between the connecting rod 20 and the transmission rod 21. This causes the rotating fixed shaft 19 to drive the transmission rod 21 to swing back and forth at a fixed angle through the connecting rod 20. A rotating shaft 22 is fixedly connected inside the moving rod 21. A brush 23 is fixedly connected to the end of the rotating shaft 22. The back-and-forth swinging transmission rod 21 drives the brush 23 to swing left and right through the rotating shaft 22. The harvested mangoes have stems attached. When the mangoes are washed in the washing machine, some of the stems fall into the equipment. Some fall to the bottom of the washing machine, and some are conveyed by the brush roller 31 into the collection box 30. The fallen stems are impurities and will damage the mangoes being washed inside the washing machine. The swinging brush 23 obstructs the mango stems on the surface of the brush roller 31, preventing the mango stems from entering the collection box 30, reducing the need for subsequent cleaning, and greatly improving production efficiency.
[0037] Working principle: First, start motor 10 to drive shaft 9 to rotate. The rotating shaft 9 drives bevel gear 8 to rotate, which in turn drives bevel gear 7 to rotate. This causes screw 6 to rotate, moving telescopic leg 4 upward and lifting trough 1. This tilts trough 1 at a fixed angle to prevent mangoes from accumulating between rollers 31 due to their irregular surface inside the washing machine. Then, start motor 15 to rotate turntable 17. The rotating turntable 17 drives the fixed shaft 19 on the outer side to rotate in a circle. Because the length of connecting rod 20 is less than the longest distance from the center point of fixed shaft 19 to the center point where connecting rod 20 connects to transmission rod 21, the circular motion is fixed. The fixed shaft 19 drives the transmission rod 21 to swing back and forth at a fixed angle via the connecting rod 20. The back-and-forth swinging transmission rod 21 drives the brush 23 to swing left and right via the rotating shaft 22. The swinging brush 23 obstructs the mango stems on the surface of the brush roller 31, causing the mango stems to enter the collection box 30, reducing the need for subsequent cleaning and greatly improving production efficiency. The mangoes are slid into the trough frame 1 via the slide plate 2, where they are cleaned by friction from the brush roller 31 while being rolled and conveyed. They are then rinsed by water sprayed from the top nozzle 25. After cleaning, the mangoes are dried by the air blower 16 and slide out of the discharge plate 29 into the collection box 30 installed at the bottom, completing the cleaning before the mango jam pre-processing.
