Description

Technical Field

[0001] The invention relates to the technical field of potato harvesting, in particular to a potato harvesting machine. Background Art

[0002] A potato harvester is a type of agricultural machinery specially used for potato harvesting. It integrates multiple functions such as digging, separation, and cleaning. It is mainly composed of an excavating device, a conveying device, a separating device, a cleaning device, and a power system. Driven by mechanical power, the excavating device goes deep into the soil to dig out the potatoes, and then the conveying device transports the potatoes to the separating device to preliminarily separate the potatoes from soil, rhizomes and other debris. The cleaning device then further removes the remaining fine impurities, so that the harvested potatoes reach a higher degree of purity. It has the advantages of high efficiency, labor saving, and guaranteed harvest quality, which can greatly improve the potato harvesting efficiency and reduce labor costs. It is widely used in large-scale potato planting harvesting operations.

[0003] During the potato harvesting process, potatoes are easily damaged due to various reasons due to operations such as digging and transportation. The collision between the digging parts of the harvester and the soil and stones may scratch or squeeze the potatoes, causing damage to the skin. During transportation, potatoes move quickly on the conveyor belt of the machine and frequently collide with each other, which can easily cause abrasions and bruises.

[0004] These injuries will cause a series of serious problems, with microbial infection being the first to be affected. The injured potatoes lose the protection of their epidermis, and bacteria, mold and other microorganisms can easily breed and multiply in the wounds. Under suitable temperature and humidity conditions, microorganisms will spread rapidly, causing the potatoes to rot and mildew, and then further deteriorate during subsequent storage and transportation. The potato loss rate is high, and ultimately, in the potato processing industry, such as the production of potato chips and French fries, if the raw potatoes are heavily damaged, they will need to be manually screened and removed, increasing labor and time costs. For this reason, it is necessary to design a potato harvester. Summary of the invention

[0005] The purpose of the present invention is to provide a potato harvester to solve the problem that potatoes are damaged during the potato harvesting process, resulting in the need for manual screening and removal in the potato processing industry, which increases labor costs and time costs.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A potato harvester comprises a machine body, a temporary storage bin is fixedly mounted on the inner wall of the machine body, a discharge port is provided on one side surface of the temporary storage bin, a sorting channel for potatoes to pass through is mounted at the discharge port position on the outer surface of the temporary storage bin, a blocking gate for controlling the passage of potatoes is arranged on the inner wall of the sorting channel, an identification component is mounted above the sorting channel, a sorting flip plate that can be flipped downward is mounted on one side of the sorting channel close to the blocking gate, a collecting box for collecting potatoes is mounted on the surface of the machine body, and a partition for partitioning the internal space of the collecting box is mounted on the inner wall of the collecting box.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0033] See also Figures 1 to 10 , the present invention provides a technical solution.

[0034] A potato harvesting machine comprises a machine body 1, a temporary storage bin 2 is fixedly mounted on the inner wall of the machine body 1, a digging shovel 26 and a conveying chain rail 27, the conveying chain rail 27 is mounted on the inner wall of the machine body 1, the digging shovel 26 and the conveying chain rail 27 are connected end to end, when the machine moves forward, the digging shovel 26 turns out potatoes in the soil and pushes them onto the conveying chain rail 27, the conveying chain rail 27 lifts the potatoes and transports them to the temporary storage bin 2, and conventionally includes a separation device, during the transportation of the potatoes by the conveying chain rail 27, the potatoes are separated from the soil by the separation device, and finally the separated potatoes are transported to the temporary storage bin 2, a discharge port is opened on one side surface of the temporary storage bin 2, and a sorting channel for potatoes to pass through is installed at the discharge port position on the outer surface of the temporary storage bin 2 3. The inner wall of the sorting channel 3 is provided with a blocking gate 5 for controlling the on and off of potatoes. Here, the word on and off refers to the connection and blocking of the channel. The surface of the sorting channel 3 is installed with a first electric push rod, and the telescopic end of the first electric push rod is fixedly connected to the blocking gate 5. By starting the first electric push rod to push the blocking gate 5 to move horizontally, the blocking gate 5 controls the on and off of potatoes. An identification component is installed above the sorting channel 3. The identification component is used to identify whether the surface of the potato is damaged. A sorting flip plate 18 that can be flipped downward is installed on the side of the sorting channel 3 close to the blocking gate 5. A collecting box 22 for collecting potatoes is installed on the surface of the body 1, and a partition plate 23 for separating the internal space of the collecting box 22 is installed on the inner wall of the collecting box 22;

[0035] The potatoes transported to the temporary storage bin 2 roll along the inclined wall of the bottom surface of the temporary storage bin 2 toward the discharge port, and fall onto the sorting channel 3 from the discharge port, and are blocked by the blocking gate 5. Then, the recognition component recognizes the potatoes on the sorting channel 3. When it is recognized that the potato has no wounds, the blocking gate 5 is removed to connect the sorting channel 3. The potatoes on the sorting channel 3 are pushed by the potatoes behind to move to the sorting flip plate 18, and fall into one of the spaces in the collecting box 22 through the sorting flip plate 18 under the action of inertia. If the recognition component recognizes that the potatoes on the sorting channel 3 are damaged, the sorting flip plate 18 is flipped downward at the same time. Then, after the blocking gate 5 is removed, the potatoes on the sorting channel 3 are pushed by the potatoes behind to fall directly, and finally fall into another space in the collecting box 22, thereby completing the screening of damaged potatoes from undamaged potatoes.

[0036] The temporary storage bin 2 is provided with a device to prevent the discharge port from being blocked, such as a lever to move potatoes stuck in the discharge port away;

[0037] The damaged potatoes are screened and separated from the undamaged potatoes, and are collected in different spaces in the collection box 22, respectively, to avoid mixing the damaged potatoes with the undamaged potatoes. The damaged potatoes are easily infected by microorganisms and further affect the surrounding potatoes. Separate storage can prevent the damaged potatoes from having an adverse effect on the quality of the undamaged potatoes, thereby ensuring the integrity and quality of the undamaged potatoes, which is beneficial to the subsequent storage, processing and sales. By sorting the damaged and undamaged potatoes, the needs of different users for potato quality grading can be met, thereby improving the practicality and market competitiveness of the equipment.

[0038] A support bracket 17 is installed on one side of the sorting channel 3 close to the blocking gate 5, and the sorting flip plate 18 is rotatably connected to the surface of the support bracket 17. A first motor is installed on the surface of the support bracket 17, and the first motor is used to drive the sorting flip plate 18 to flip.

[0039] A second guide plate 24 is fixedly connected to the inner wall of the machine body 1 , and the second guide plate 24 is used to guide the potatoes rolling down from the horizontal sorting flip plate 18 to fall into the collecting box 22 .

[0040] A sorting slot 19 is arranged directly below the sorting flip plate 18, and the sorting slot 19 can be used for the sorting flip plate 18 to be flipped downward and placed. The sorting slot 19 is fixedly connected to the body 1, and a blocking inclined plate 20 is fixedly connected to the surface of the sorting slot 19, and a first guide plate 21 is fixedly connected to the surface of the blocking inclined plate 20. Please refer to Fig.11 Since the sorting slot 19 is located directly below the sorting flip plate 18, when the sorting flip plate 18 flips downward, it will be placed in the internal space of the sorting slot 19. Therefore, the conventionally set width and depth of the sorting slot 19 can be used for the sorting flip plate 18 to flip downward and enter. When the sorting flip plate 18 flips downward and is placed in the sorting slot 19, the potatoes falling from the sorting channel 3 will fall into the sorting slot 19. At this time, the potatoes will be blocked and restricted in the sorting slot 19 by the blocking inclined plate 20, and then the sorting flip plate 18 is flipped upward to push the potatoes to move obliquely upward along the inclined surface of the blocking inclined plate 20 until they are pushed to the surface of the first guide plate 21, and then slide along the surface of the first guide plate 21 into the collection box 22. By arranging the ends of the first guide plate 21 and the second guide plate 24 to be located above different spaces inside the collection box 22, the potatoes can slide into different spaces.

[0041] The sorting and turning plate 18 can realize the sorting and transferring operations of damaged potatoes through the basic downward turning and upward turning actions.

[0042] The inner surface of the blocking gate 5 is rotatably connected with an auxiliary roller 6 for contacting potatoes, and the bottom wall of the sorting channel 3 is installed with a transmission belt conveyor 4. When the blocking gate 5 blocks the potatoes, the transmission belt conveyor 4 is started to make the bottom of the potatoes have a force to move toward the blocking gate 5, and the potatoes are blocked and cannot move horizontally, and one side is in contact with the rotatable auxiliary roller 6 on the blocking gate 5, so that the potatoes are in a rolling state on the transmission belt conveyor 4. By rolling the potatoes, the potatoes are turned over to prevent the bottom of the potatoes from being unable to be recognized by the recognition component.

[0043] By rolling the potatoes on the transmission belt conveyor 4, all sides of the potatoes can have a chance to be detected by the identification component, avoiding the situation where only the upper surface of the potato is detected while damage to other parts such as the bottom is missed, thereby greatly improving the comprehensiveness and accuracy of the identification of potato surface damage, ensuring that there will be no misjudgment during sorting, and the damaged potatoes are accurately screened out. During the continuous operation of the equipment, the rolling and turning of the potatoes are closely coordinated with the overall conveying, identification, and sorting processes, making the entire operation process smoother. This setting does not require the addition of a complex mechanical structure or a strong force to turn the potatoes, reducing the overall burden of the equipment.

[0044] The blocking gate 5 is arranged to be inclined inwardly, so that the potatoes will not run upward when rolling.

[0045] The identification component includes a detection and identification frame 7 and a damage detector 8, such as a linear array CCD camera. The detection and identification frame 7 is installed at the upper end of the sorting channel 3, and the damage detector 8 is installed on the inner top wall of the detection and identification frame 7. Conventionally, a shock absorbing device is installed at the connection between the detection and identification frame 7 and the sorting channel 3 to reduce the vibration of the detection and identification frame 7. The surface of the detection and identification frame 7 is provided with a glue coating component, which is used to apply biological glue to the damaged part of the potato.

[0046] Bio-glue contains biologically active ingredients. After being applied to the damaged part of potatoes, it can provide a suitable environment for the cells at the wound, promote cell division and growth, accelerate wound healing, and enable the potatoes to better maintain their integrity and physiological functions after harvest. In addition, applying bio-glue can form a protective film on the surface of the wound, isolating the wound from the external environment and preventing the invasion of microorganisms, thereby extending the storage life of potatoes and reducing the rot rate. It will also reduce the loss of water at the wound and slow down the oxidation process, which helps to maintain the freshness, taste and nutritional value of potatoes, making them more competitive in the market. Bio-glue suitable for potatoes can be chitosan obtained by deacetylation of chitin in the shells of crustaceans such as shrimps and crabs, natural polysaccharides (sodium alginate) extracted from brown algae, gelatin extracted from animal skins and bones, a polysaccharide substance produced by microbial fermentation (gellan gum), and a water-insoluble polysaccharide (curdlan) obtained by microbial fermentation.

[0047] The glue coating component includes a pumping pump 12, a storage tank 13 and a pipeline component. The storage tank 13 is installed on the surface of the detection and identification frame 7. The pumping pump 12 is installed on the surface of the storage tank 13. One end of the pipeline component is connected to the output end of the pumping pump 12, and the other end is movable through the surface of the detection and identification frame 7 and is placed on the inner side of the detection and identification frame 7. By starting the pumping pump 12, the biological glue in the storage tank 13 is extracted and transported through the pipeline component, so that the other end of the pipeline component is applied to the damaged part of the potato surface. Conventionally, the storage tank 13 is provided with a temperature control device. Conventionally, the biological glue is in a pumpable state. For example, chitosan is selected as the biological glue, dissolved in an acetic acid solution with a mass fraction of 2%, and prepared into a solution with a concentration of 1%-3%. Under the temperature condition of 30-40°C, the solution is in a pumpable state. It is adapted to a screw pump, and is matched with a corrosion-resistant plastic pipe and a fan-shaped nozzle to achieve coating on the potato surface.

[0048] The pipeline assembly includes a delivery hose 11 and a spray nozzle 10. One end of the spray nozzle 10 is connected to the output end of the pumping pump 12, and the other end is coaxially installed with a rotating sleeve 28. The rotating sleeve 28 and the spray nozzle 10 are coaxially rotatably connected. An electric mechanical arm 9 is installed on the inner wall of the detection and identification frame 7. The electric mechanical arm 9 is used to drive the spray nozzle 10 to move and apply. The delivery hose 11 is rotatably connected to the spray nozzle 10 with the help of the rotating sleeve 28. In this way, when the electric mechanical arm 9 drives the spray nozzle 10 to move, even if the spray nozzle 10 rotates, it will not cause the delivery hose 11 to twist.

[0049] The surface of the storage tank 13 is connected with a horizontally movable conveying pipe return slider 14, and the surface of the storage tank 13 is provided with a slide groove 15 for horizontal movement of the conveying pipe return slider 14, and a return spring 16 is fixedly connected between the groove wall of the slide groove 15 and the conveying pipe return slider 14, and the conveying pipe return slider 14 is located between the conveying hose 11 and the detection and identification frame 7. When the electric mechanical arm 9 drives the spray nozzle 10 to move, so that the conveying hose 11 is pulled into the detection and identification frame 7, it will push the conveying pipe return slider 14 to move along the track of the slide groove 15 toward the detection and identification frame 7, so that the return spring 16 will be deformed and store elastic potential energy. When the electric mechanical arm 9 moves in the opposite direction, the conveying pipe return slider 14 will no longer have the thrust of the conveying hose 11. Under the elastic force of the return spring 16, the conveying pipe return slider 14 moves in the opposite direction, which will push the conveying hose 11 and pull the conveying hose 11 out of the detection and identification frame 7 to prevent the conveying hose 11 from being dragged in the detection and identification frame 7 and affecting the potatoes.

[0050] An ejection box 25 is installed inside the body 1, and a second electric push rod is installed inside the ejection box 25. The output end of the second electric push rod is fixedly connected to the collection box 22. By starting the second electric push rod, the collection box 22 is pushed to the outside of the body 1, so that potatoes in the collection box 22 can be easily removed.

[0051] The specific scheme is as follows: the harvesting machine is started to move forward in the field. When the machine moves forward, the digging shovel 26 goes deep into the soil, turns out the potatoes in the soil, and pushes them onto the conveying chain track 27. The conveying chain track 27 transports the potatoes to the temporary storage bin 2 fixedly installed on the inner wall of the machine body 1. The potatoes in the temporary storage bin 2 roll along the inclined wall of the bottom surface of the temporary storage bin 2 toward the discharge port, and fall from the discharge port onto the sorting channel 3. At this time, the blocking gate 5 is in a blocking state, preventing the potatoes from continuing to move forward.

[0052] The damage detector 8 on the top wall of the detection and identification frame 7 detects the potatoes on the sorting channel 3 to determine whether the surface is damaged. During the detection process, the transmission belt conveyor 4 is started to generate a force at the bottom of the potato to move toward the blocking gate 5. Since one side of the potato is in contact with the rotatable auxiliary roller 6 on the blocking gate 5 and is blocked by the blocking gate 5 and cannot move horizontally, it is in a rolling state on the transmission belt conveyor 4, and is turned over to ensure that all sides of the potato can be detected by the identification component.

[0053] When the identification component detects that the potato is damaged, the pumping pump 12 is started to extract the bio-glue in the storage tank 13. The bio-glue is sprayed out from the spray nozzle 10 through the delivery hose 11 and applied to the damaged part of the potato surface. The electric mechanical arm 9 drives the spray nozzle 10 to move and apply. During the movement of the spray nozzle 10, if the delivery hose 11 is pulled toward the detection and identification frame 7, the delivery tube return slider 14 will be pushed to move along the slide groove 15 track toward the detection and identification frame 7, causing the reset spring 16 to deform and store elastic potential energy; when the electric mechanical arm 9 moves in the opposite direction, the delivery tube return slider 14 moves in the opposite direction under the action of the elastic force of the reset spring 16, pushing the delivery hose 11 to be pulled outward from the detection and identification frame 7.

[0054] When it is identified that the potatoes are damaged, the first motor on the surface of the support bracket 17 is started to drive the sorting flip plate 18 to flip downward. If it is identified that the potatoes are not damaged, the sorting flip plate 18 remains in a horizontal state.

[0055] Then, if the sorting flip plate 18 is kept in a horizontal state, the first electric push rod is started to push the blocking gate plate 5 to move, so that the sorting channel 3 is connected, and the potatoes on the sorting channel 3 are pushed by the potatoes behind, or the transmission belt conveyor 4 is started to drive the potatoes to move, move to the sorting flip plate 18, and pass through the sorting flip plate 18 under the action of inertia, and fall into one of the spaces in the collecting box 22 along the guidance of the second guide plate 24; if the sorting flip plate 18 is in a downward state, the potatoes on the sorting channel 3 are pushed by the potatoes behind, and after passing through the sorting channel 3, they directly fall into the sorting trough 19, and are blocked and restricted by the blocking inclined plate 20. Subsequently, the first motor is reversed to flip the sorting flip plate 18 upward, and push the potatoes to move obliquely upward along the inclined surface of the blocking inclined plate 20 until they are pushed to the surface of the first guide plate 21, and then slide along the first guide plate 21 to another space in the collecting box 22, completing the sorting of damaged and undamaged potatoes.

[0056] After the operation is completed, the second electric push rod in the push box 25 is started, and its output end pushes the collection box 22 to move to the outside of the machine body 1, so that the staff can take out the potatoes in the collection box 22 for subsequent processing.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
