Description

Technical Field

[0001] This invention relates to the field of hawthorn production and processing technology, specifically to a hawthorn fruit raw material sorting device for the production and processing of dried hawthorn slices. Background Technology

[0002] Hawthorn berries are rich in nutrients and highly beneficial to human health. Nowadays, hawthorn berries are often processed into dried hawthorn slices and other food products, which are very popular. During hawthorn fruit production and processing, the raw materials need to be sorted first, selecting fresh fruits of suitable ripeness and good quality, while removing diseased, rotten, and impurity fruits. This sorting and removal process is generally done manually, which is time-consuming, labor-intensive, and has relatively low speed and efficiency.

[0003] Chinese patent CN109078745A discloses a hawthorn fruit raw material sorting device for the production and processing of dried hawthorn slices, which can quickly sort out diseased, insect-infested and rotten hawthorn fruits without the need for manual sorting.

[0004] However, although the above-mentioned device can sort out the bad hawthorn fruits, it cannot screen the hawthorn fruits by size. Further screening is required, and mud and sand will remain on the surface of the screened hawthorn fruits, which is not conducive to subsequent processing. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the present invention proposes a hawthorn fruit raw material sorting device for the production and processing of dried hawthorn slices, so as to solve the above problems.

[0006] The objective of this invention is achieved through the following technical solution: This invention provides a hawthorn fruit raw material sorting device for the production and processing of dried hawthorn slices, comprising: The sorting water tank has an inlet at one end and an outlet at the other end. A water storage tank is connected to an inlet pipe and an outlet pipe respectively. A first water pump is installed on the inlet pipe and is connected to the inlet. The outlet pipe is connected to the outlet. The screening mechanism includes multiple screening units arranged at intervals in the sorting tank. Each screening unit includes a rotating roller. Two rotating rollers are respectively rotatably installed at the top and bottom ends of the sorting tank. Multiple conveyor bars are arranged around the two rotating rollers. A screening area is formed between two adjacent conveyor bars. The width of the screening area of ​​each screening unit decreases from the inlet to the outlet. A transmission mechanism for driving the conveyor bar to move downwards on the side near the inlet; The discharge bin is located at the bottom of the sorting water tank on the side of each screening mechanism near the water inlet. One end of the discharge bin is connected to the sorting water tank and the other end is provided with a discharge port facing downwards. The inner wall of the discharge bin is provided with cleaning bristles. Each discharge bin is provided with a boosting mechanism that can drive the hawthorn fruit to roll through the cleaning bristles. The rejection mechanism is used to remove bad hawthorn fruit from the raw material.

[0007] Furthermore, the boosting mechanism includes a pusher plate, a booster roller, and a rack plate. A plurality of notches are provided on one side of the discharge bin, and a booster roller is rotatably mounted on the outer side of each notch. One side of the booster roller extends into the notch and is provided with a booster brush, while the other side is provided with a drive tooth. The pusher plate is located outside the discharge port and has sliding plates on both sides that are slidably connected to the outer wall of the discharge bin. A spring is connected between the sliding plate and the outer wall of the discharge bin. The rack plate is connected to the sliding plate and meshes with each drive tooth.

[0008] Furthermore, the upper roller in each of the screening mechanisms is offset toward the inlet so that the top of the conveyor bar is tilted toward the inlet.

[0009] Furthermore, each of the screening mechanisms has a backing plate on the inner side of the conveyor bar, the backing plate being attached to the side of the conveyor bar near the water inlet, and the backing plate having multiple passages facing each screening area.

[0010] Furthermore, the transmission mechanism includes a belt and a motor. A belt is respectively arranged around the top rollers of two adjacent screening mechanisms. The motor is installed on the outside of the sorting tank and is connected to one of the rollers for transmission.

[0011] Furthermore, the rejection mechanism includes a first conveyor belt, a rejection channel, and a defective fruit basket. The first conveyor belt is installed in the sorting tank near the water inlet. One end of the first conveyor belt is submerged below the water surface, and the other end extends obliquely upward in a direction away from the water inlet. The drive shaft of the first conveyor belt and one of its rotating rollers are respectively provided with meshing first gears. The rejection channel is installed at the top of the sorting tank and located below the other end of the first conveyor belt. The defective fruit basket is located on one side of the outer wall of the sorting tank and below the rejection channel, and the bottom surface of the rejection channel slopes downward toward the defective fruit basket.

[0012] Furthermore, it also includes a residual material collection mechanism, which includes a second conveyor belt and a residual material basket. The second conveyor belt is installed in the sorting tank near the outlet. One end of the second conveyor belt is located at the bottom of the sorting tank, and the other end is inclined upward towards the outlet and extends out of the sorting tank. The residual material basket is installed on the outer wall of the sorting tank and located below the other end of the second conveyor belt. The drive shaft of the second conveyor belt and one of its rotating rollers are respectively provided with mutually meshing second gears.

[0013] Furthermore, both the first and second conveyor belts have a mesh surface, and multiple pusher bars are evenly distributed on the outer side of the first and second conveyor belts along the conveying direction.

[0014] Furthermore, the bottom of the sorting tank is provided with multiple sets of spray nozzles on the side of each screening mechanism near the water inlet. Each set of spray nozzles includes multiple water outlets. The bottom of each set of spray nozzles is connected to a spray pipe. A second water pump is installed on the spray pipe and connected to the water storage tank.

[0015] Furthermore, a water receiving tank is provided below the sorting water tank, and multiple material receiving baskets are respectively provided on the top of the water receiving tank below each discharge bin. A filter screen plate is provided at the bottom of each material receiving basket. A return water pipe connected to the water storage tank is provided on the water receiving tank, and a third water pump is installed on the return water pipe.

[0016] As can be seen from the above technical solution, the present invention provides a hawthorn fruit raw material sorting device for the production and processing of dried hawthorn slices: 1. The water storage tank and the sorting tank are connected end to end by the inlet and outlet pipes. Water is pumped into the inlet by the first water pump, creating a unidirectional circulating water flow in the sorting tank. The water flow generates thrust to push the hawthorn fruits sequentially through each screening mechanism. The fruit size is sorted by the different width screening areas in the screening mechanism, achieving classification and sorting of hawthorn fruits by size. The transmission mechanism drives the conveyor bar near the inlet to move downwards, so that the fruits that are stuck on the conveyor bar due to the thrust of the water flow can be transferred into the discharge bin. This can promptly transfer the sorted hawthorn fruits and prevent the fruits from piling up on the conveyor bar. After passing through the discharge bin, the fruits are assisted by the push mechanism to roll and push, so that the fruits can be thoroughly cleaned by the cleaning bristles. Some water flows into the discharge bin to wash away the fruits and the dirt remaining on the cleaning bristles, improving the fruit cleaning effect. This invention can simultaneously achieve the screening of bad fruits, the sorting of fruit size, and the cleaning of fruits, which is beneficial to improving the sorting efficiency of hawthorn fruits and reducing intermediate steps. 2. A portion of the water flow, along with hawthorn berries blocked by the corresponding screening mechanism, will be sent into the discharge hopper. The hawthorn berries will move along the internal channel of the discharge hopper and have their surface dirt washed away by the cleaning bristles. The dirt is rinsed off by the water flow to promote its removal from the cleaning bristles and the surface of the hawthorn berries. When the hawthorn berries fall out of the discharge port, they will collide with the push plate. The impact force will push the push plate away from the discharge port, and then, under the action of the spring, it can be pulled back by the sliding plate. As more fruits fall, the sliding plate will drive the rack plate to move back and forth. The rack plate will drive each push roller to rotate repeatedly in both directions, thus allowing each push brush to swing back and forth in the discharge hopper. When subsequent hawthorn berries pass through the discharge hopper, the push brushes can make the hawthorn berries rotate, so that the surface of the fruit can be thoroughly washed by the cleaning bristles. At the same time, the push brushes can also help push some slightly larger fruits to prevent them from getting stuck in the discharge hopper and causing the channel to be blocked.

Detailed Implementation

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] like Figure 1-7 As shown in the figure, the hawthorn fruit raw material sorting device for the production and processing of dried hawthorn slices provided in this embodiment includes a sorting water tank 1, a water storage tank 2, a screening mechanism 3, a transmission mechanism 4, a discharge tank 5, a boosting mechanism 6, and a rejection mechanism 7.

[0021] The sorting trough 1 is elongated and open at the top. One end of the trough 1 has a water inlet 11, and the other end has a water outlet 12. It should be noted that the hawthorn fruits to be sorted should be fed into the trough 1 from the top end closest to the water inlet 11. Preferably, a feeding plate is provided at the top of the trough 1 above the water inlet 11 to allow the hawthorn fruits to be poured into the trough 1.

[0022] The water storage tank 2 is connected to an inlet pipe 21 and an outlet pipe 22. A first water pump 23 is installed on the inlet pipe 21 and connected to the inlet 11. The first water pump 23 pumps water from the water storage tank 2 into the sorting tank 1. The outlet pipe 22 is connected to the outlet 12. One end of the outlet pipe 22 is connected to the top of the water storage tank 2, and the other end is connected to the outlet 12. The outlet 12 is higher than the top of the water storage tank 2 to allow water to flow into the sorting tank 1. Water is pumped into the sorting tank 1 through the inlet pipe 21 and returned to the water storage tank 2 through the outlet 12, achieving water circulation and ensuring continuous flow of water from the inlet 11 to the outlet 12 within the sorting tank 1.

[0023] Preferably, the water storage tank 2 is also connected to a water supply pipe, which is connected to an external water source to replenish water into the water storage tank 2.

[0024] Multiple screening mechanisms 3 are arranged at intervals in the sorting tank 1. Each screening mechanism 3 is arranged sequentially along the direction of water flow. Each screening mechanism 3 includes a rotating roller 31. Two rotating rollers 31 are respectively rotatably installed at the top and bottom ends of the sorting tank 1. Multiple conveying strips 32 are arranged around the two rotating rollers 31. Specifically, multiple annular grooves for limiting the conveying strips 32 are arranged at intervals on the rotating rollers 31 so that the conveying strips 32 are embedded in the corresponding annular grooves to prevent displacement. The interval between two adjacent conveying strips 32 forms a screening area 33. The width of the screening area 33 of each screening mechanism 3 decreases from the inlet 11 to the outlet 12. Hawthorn fruits entering from the sorting tank 1 near the inlet 11 are pushed by the water flow through various screening mechanisms 3. Since the width of each screening area 33 decreases from the inlet 11 to the outlet 12, larger hawthorn fruits will be blocked by the earlier screening mechanism 3, and smaller hawthorn fruits will be blocked by the subsequent screening mechanisms 3 step by step, thus achieving the sorting of hawthorn fruits by size.

[0025] The transmission mechanism 4 is used to drive the conveyor bar 32 to move downwards on the side near the inlet 11.

[0026] Specifically, the transmission mechanism 4 includes a belt 41 and a motor 42. A belt 41 is arranged around the top rollers 31 of two adjacent screening mechanisms 3. When one roller 31 rotates, it will drive the adjacent roller 31 to rotate through the belt 41. The motor 42 is installed on the outside of the sorting tank 1 and is connected to one of the rollers 31 for transmission. The output shaft end of the motor 42 is connected to the end of the roller 31 to drive the roller 31.

[0027] One discharge bin 5 is located at the bottom of the sorting tank 1 on the side of each screening mechanism 3 near the inlet 11. One end of the discharge bin 5 is connected to the sorting tank 1, and the other end has a discharge port 51 facing downwards. The inner wall of the discharge bin 5 is provided with cleaning bristles 52. The inner height of the discharge bin 5 is similar to the diameter of the hawthorn fruit blocked in the fruit screening area 33 of the corresponding screening mechanism 3. This allows the surface of the hawthorn fruit to come closer to the cleaning bristles 52 when hawthorn fruit of a certain size passes through the corresponding discharge bin 5, so that the discharge bins 5 at each screening mechanism 3 can effectively clean the surface dirt of the hawthorn fruit. Each discharge bin 5 is provided with a propulsion mechanism 6, which can drive the hawthorn fruit to tumble through the cleaning bristles 52 and promote the discharge of the hawthorn fruit from the discharge bin 5, preventing the hawthorn fruit from clogging in the discharge bin 5.

[0028] like Figure 5 and Figure 7As shown, in one embodiment, the boosting mechanism 6 includes a pusher plate 61, a booster roller 62, and a rack plate 63. A plurality of notches 53 are provided on one side of the discharge bin 5. A booster roller 62 is rotatably mounted on the outer side of each notch 53. One side of the booster roller 62 extends into the notch 53 and is provided with a booster brush 621, while the other side is provided with a drive tooth 622. When the booster roller 62 rotates, it drives the booster brush 621 to sway within the discharge bin 5. The pusher plate 61 is located outside the discharge port 51, and its two sides are provided with sliding joints that are slidably connected to the outer wall of the discharge bin 5. The sliding plate 64 can move the push plate 61 closer to or away from the discharge port 51. A spring 65 is connected between the sliding plate 64 and the outer wall of the discharge bin 5. The spring 65 can provide elastic force to pull the push plate 61 towards the discharge port 51 through the sliding plate 64. It should be noted that although the spring 65 can pull the push plate 61 towards the discharge port 51, there is still a distance between the push plate 61 and the discharge port 51 for the hawthorn fruit to fall out of the discharge bin 5. The rack plate 63 is fixedly connected to the sliding plate 64 and meshes with each drive tooth 622 respectively.

[0029] In actual use, a portion of the water flow and the hawthorn fruits blocked by the corresponding screening mechanism 3 will be sent into the discharge bin 5. The hawthorn fruits will move along the internal channel of the discharge bin 5 and be brushed by the cleaning bristles 52 to wash the dirt on their surface. The dirt is washed away by the water flow to promote its removal from the cleaning bristles 52 and the surface of the hawthorn fruits. When hawthorn fruits fall from the discharge port 51, they will collide with the push plate 61. The impact force will push the push plate 61 away from the discharge port 51. Then, under the action of the spring 65, the sliding plate 64 can pull the push plate 61 back. As more fruits fall, the sliding plate 64 will drive the rack plate 63 to move back and forth. The rack plate 63 will drive each push roller 62 to rotate repeatedly in the forward and reverse directions, so that each push brush 621 can swing back and forth in the discharge bin 5. When subsequent hawthorn fruits pass through the discharge bin 5, the push brush 621 can make the hawthorn fruits rotate, so that the surface of the fruit is thoroughly cleaned by the cleaning bristles 52. At the same time, the push brush 621 can also help push some slightly larger fruits to prevent the fruits from getting stuck in the discharge bin 5 and causing the channel to be blocked.

[0030] Preferably, the surface of the push plate 61 is provided with an elastic protective layer, which can be made of silicone or rubber to prevent the hawthorn fruit from being damaged when it is impacted.

[0031] It should be noted that the push plate 61 is set at an angle so that the hawthorn fruit can roll off on its own after falling onto the push plate 61, thus avoiding the accumulation of fruit.

[0032] The rejection mechanism 7 is used to remove bad hawthorn fruit from the raw material.

[0033] Specifically, the rejection mechanism 7 includes a first conveyor belt 71, a rejection channel 72, and a spoiled fruit basket 73. The first conveyor belt 71 is installed in the sorting tank 1 at one end near the inlet 11, in the area between the screening mechanism 3 and the inlet 11. One end of the first conveyor belt 71 is submerged below the water surface, and the other end extends obliquely upward away from the inlet 11. The first conveyor belt 71 is driven by a drive shaft. The drive shaft of the first conveyor belt 71 and one of the rotating rollers 31 are respectively provided with meshing first gears 43. When the transmission mechanism 4 drives the rotating roller 31 to rotate, the two first gears 43 will synchronously drive the drive shaft of the first conveyor belt 71 to rotate. The rejection channel 72 is installed at the top of the sorting tank 1 and below the other end of the first conveyor belt 71. The spoiled fruit basket 73 is set on one side of the outer wall of the sorting tank 1 and below the rejection channel 72. The bottom surface of the rejection channel 72 is inclined downward toward the spoiled fruit basket 73. When the hawthorn fruits to be sorted are poured into the sorting tank 1 near the water inlet 11, diseased, rotten, and other bad fruits will float on the water surface due to the cavities and gas inside, while fresh, good fruits will sink naturally. As the water flows in the sorting tank 1, the floating bad fruits will be pushed to the end of the first conveyor belt 71 that is submerged in the water. As the first conveyor belt 71 is conveyed, these bad fruits will be transported along the belt surface of the first conveyor belt 71 and fall onto the rejection channel 72, and finally roll into the bad fruit basket 73 for unified collection for subsequent processing.

[0034] In use, the device pumps water from the storage tank 2 into the sorting tank 1 through the inlet 11 via the first water pump 23, creating a continuous flow of water within the sorting tank 1. This water flow has a thrust that pushes objects in the water toward the outlet 12. The hawthorn fruits to be sorted are poured into the sorting tank 1 near the inlet 11. Damaged fruits float on the surface and are pushed by the water flow to the rejection mechanism 7 for separation and collection. Good fruits sink into the water and are pushed by the water flow to various screening mechanisms 3. Hawthorn fruits larger than those passing through the screening area 33 are blocked by the corresponding screening mechanism 3 and remain between adjacent conveyor bars 32. Hawthorn fruits smaller than those passing through the screening area 33 pass smoothly to the next screening mechanism 3 for screening, thereby achieving fruit size sorting. The transmission mechanism 4 drives each roller 31 to rotate, which in turn drives the conveyor bar 32 to move downward on the side near the water inlet 11. The fruit blocked on the conveyor bar 32 will be sent into the discharge bin 5 as the conveyor bar 32 moves. When the hawthorn fruit passes through the discharge bin 5, it is brushed by the cleaning bristles 52 and assisted in rolling and pushing by the booster mechanism 6, and finally discharged from the discharge bin 5 and collected in a container.

[0035] This invention utilizes a rejection mechanism 7 to separate damaged fruit from good fruit and collects the damaged fruit for convenient subsequent processing. A water storage tank 2 is connected to a sorting tank 1 via an inlet pipe 21 and an outlet pipe 22. A first water pump 23 pumps water into the inlet 11, creating a unidirectional circulating water flow within the sorting tank 1. This water flow generates thrust, propelling the hawthorn fruits sequentially through each screening mechanism 3. The different widths of the screening areas 33 within each screening mechanism 3 are used to categorize the fruit by size, achieving a classification and screening process based on size. The transmission mechanism 4 drives the conveyor bar 32 to move downwards near the water inlet 11, thus carrying the fruits that are stuck on the conveyor bar 32 due to the water flow into the discharge bin 5. This allows for the timely transfer of hawthorn fruits after size selection, preventing fruit accumulation on the conveyor bar 32. Inside the discharge bin 5, the fruits are assisted by the pushing mechanism 6 to roll and push, ensuring thorough cleaning by the cleaning brush bristles 52. Some water flows into the discharge bin 5, rinsing away residual dirt on the fruits and cleaning brush bristles 52, improving the fruit cleaning effect. This invention can simultaneously remove damaged fruits, select fruits by size, and clean the fruits, improving the sorting efficiency of hawthorn fruits and reducing intermediate steps.

[0036] Preferably, the upper roller 31 in each screening mechanism 3 is offset towards the water inlet 11 so that the top of the conveyor bar 32 is inclined towards the water inlet 11. When the hawthorn fruit is blocked by the conveyor bar 32 of the screening mechanism 3, the fruit can move along the inclined conveyor bar 32 towards the bottom of the sorting tank 1 under the thrust of the water flow so that the fruit can be sent into the discharge bin 5.

[0037] To prevent the hawthorn fruits blocked on the conveyor strip 32 from being excessively squeezed and deformed by the thrust of the water flow, causing the fruits that should have been blocked to pass through the corresponding screening mechanism 3, preferably, each screening mechanism 3 has a baffle plate 34 on the inner side of the conveyor strip 32. The baffle plate 34 is attached to the side of the conveyor strip 32 near the water inlet 11. The baffle plate 34 has multiple through holes 341 facing each screening area 33. The width of the through holes 341 is adapted to the width of the screening area 33. The baffle plate 34 can provide rigid support for the conveyor strip 32, and the through holes 341 can prevent the hawthorn fruits from squeezing through the conveyor strip 32 and passing through the screening mechanism 3.

[0038] In one embodiment, a residual material collection mechanism 8 is also included, which includes a second conveyor belt 81 and a residual material basket 82. The second conveyor belt 81 is installed in the sorting tank 1 at one end near the outlet 12, in the area between the screening mechanism 3 and the outlet 12. One end of the second conveyor belt 81 is located at the bottom of the sorting tank 1, and the other end is inclined upward towards the outlet 12 and extends out of the sorting tank 1. The residual material basket 82 is installed on the outer wall of the sorting tank 1 and located below the other end of the second conveyor belt 81. The second conveyor belt 81 is driven by a drive shaft. The drive shaft of the second conveyor belt 81 and one of the rotating rollers 31 are respectively provided with mutually meshing second gears 44. When the transmission mechanism 4 drives the rotating roller 31 to rotate, the two second gears 44 will synchronously drive the drive shaft of the second conveyor belt 81 to rotate. When small fruits or fruit stems pass through the last screening mechanism 3, they will be blocked by the second conveyor belt 81 and transported to the waste bin 82 along with the second conveyor belt 81, so as to collect the waste materials and prevent the waste materials from flowing back to the water storage tank 2 with the water flow.

[0039] Preferably, the belt surfaces of the first conveyor belt 71 and the second conveyor belt 81 are both mesh belt surfaces to facilitate water flow and reduce flow resistance. Furthermore, multiple pusher bars are evenly distributed on the outer sides of the belt surfaces of the first conveyor belt 71 and the second conveyor belt 81 along the conveying direction. The pusher bars can lift up damaged fruits or leftover materials to prevent objects from rolling back into the water.

[0040] In one embodiment, the bottom of the sorting trough 1 is provided with multiple sets of spray nozzles 13 on the side of each screening mechanism 3 near the water inlet 11. Each set of spray nozzles 13 includes multiple evenly distributed branch nozzles 131. The openings of each branch nozzle 131 are inclined upward and face the interception surface of the corresponding screening mechanism 3. The bottom of each set of spray nozzles 13 is connected to a spray pipe 14. A second water pump 15 is installed on the spray pipe 14 and connected to the water storage tank 2. The second water pump 15 can pump water from the water storage tank 2 to the spray nozzles 13, so that the bottom of the sorting trough 1 forms an upward thrust. This can prevent the fruit from sinking to the bottom of the sorting trough 1 and provide additional pushing force to promote water flow.

[0041] Preferably, a water receiving tank 16 is provided below the sorting water tank 1. The top of the water receiving tank 16 is located below each discharge bin 5 and a plurality of receiving baskets 161 are respectively provided. The receiving baskets 161 are used to receive the hawthorn fruits after washing in each discharge bin 5. A filter screen plate 162 is provided at the bottom of the receiving baskets 161 to filter excess water into the water receiving tank 16. A return water pipe 163 connected to the water storage tank 2 is provided on the water receiving tank 16. A third water pump 164 is installed on the return water pipe 163. The third water pump 164 can pump the water in the water receiving tank 16 back to the water storage tank 2 to reduce water loss.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
