Description

Technical Field

[0001] The invention relates to the technical field of vegetable leaf harvesters, in particular to a flushing and decontamination vegetable leaf harvester. Background Art

[0002] The leaves need to be harvested after they mature. In order to improve the efficiency of harvesting, a harvester is used instead of traditional manual harvesting. In order to avoid the roots and stems of the leaves remaining on the leaves, only the leaves need to be cut off during harvesting. At the same time, mud and impurities adhere to the harvested leaves, so they need to be cleaned. For example, a green cabbage harvester with publication number CN110946003A includes a frame, a walking mechanism and a cutting and conveying device. The cutting and conveying assembly includes a frame, a leaf cutting component, a root and stem dividing device and a flexible clamping and conveying device. The flexible clamping and conveying device includes a first clamping and conveying component, a second clamping and conveying component and a flexible adjusting mechanism. The first clamping and conveying component and the second clamping and conveying component are arranged relative to each other. A clamping and conveying channel for straightening and clamping the head is formed between the first clamping and conveying component and the second clamping and conveying component. The flexible adjusting mechanism is used to adaptively adjust the width of the clamping and conveying channel according to the size of the head. The cabbage heads are straightened and clamped in the process of entering the clamping and conveying channel, and the width of the clamping and conveying channel is adaptively adjusted according to the size of the cabbage heads, so that cabbage heads of different sizes can be effectively clamped and conveyed, thereby improving the reliability of cabbage head transportation and reducing the damage rate of cabbage heads during transportation;

[0003] For example, the publication number CN108966796A is a pickled mustard tuber harvester, which is used to solve the problem of pickled mustard tuber harvesting in the prior art. It comprises: a power assembly, a harvesting assembly installed on the power assembly, the harvesting assembly is driven by the power assembly to move forward or backward in a straight line; the harvesting assembly comprises: a vegetable leaf cutting device, the vegetable leaf cutting device is suspended and located at the front of the pickled mustard tuber harvester, the vegetable leaf cutting device; a vegetable stem cutting and conveying device, the vegetable stem is located at the rear and lower part of the vegetable leaf cutting device, and the vegetable stem cutting and conveying device is used to cut and convey the vegetable stem. Directly removing the vegetable leaves effectively saves subsequent processing steps. However, the above-mentioned harvester still has the following disadvantages during actual use:

[0004] 1. Most traditional harvesters do not have a structure for cleaning the leaves when harvesting them. They usually need to be rinsed centrally after harvesting, which not only prolongs the entire harvesting time but also reduces the freshness of the leaves. Alternatively, they use vibration to clean the leaves, which is not clean enough.

[0005] 2. At the same time, some harvesters use liquid flushing for cleaning. After cleaning, a large amount of liquid remains on the surface of the leaves. There is a lack of structure to remove excess water, which leads to the subsequent accumulation and rotting of the leaves.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original vegetable leaf harvester. Summary of the invention

[0007] The object of the present invention is to provide a vegetable leaf harvester with a flushing and decontamination function, so as to solve the problem that most traditional harvesters proposed in the above background technology do not have a structure for cleaning the vegetable leaves when harvesting them, and usually require centralized flushing after the harvesting is completed. At the same time, some harvesters use liquid flushing for cleaning, and after cleaning, a large amount of liquid remains on the surface of the vegetable leaves, and there is a lack of structure for removing excess moisture.

[0008] To achieve the above object, the present invention provides the following technical solution: a washing and decontamination vegetable leaf harvester, provided with a frame, a material receiving plate fixed at the left end of the frame, and a cutter provided at the left end edge of the material receiving plate, a conveyor belt installed inside the frame, and baffles fixed at equal intervals on the surface of the conveyor belt;

[0009] The invention comprises: a motor installed on the outer side of the frame, wherein the output shaft of the motor is connected to a connecting shaft, and the outer side of the connecting shaft is connected to the end of the transmission shaft through a pulley mechanism, and a guide plate is fixed on the outer side of the transmission shaft, and the guide plates are distributed at equal angles on the transmission shaft, and the edge of the guide plate away from the transmission shaft is an arc structure;

[0010] A flushing mechanism is arranged on the guide plate, the flushing mechanism is communicated with a water storage tank, and the water storage tank is fixed to the outside of the frame;

[0011] The recovery component is arranged on the inner side of the conveyor belt, and the recovery component is also interconnected with the water tank.

[0012] Preferably, the flushing mechanism includes spray nozzles fixed at equal intervals at the edge of the guide plate, and the guide plate is hollow inside, and connection holes are reserved on the back of the guide plate. Liquid is sprayed from the spray nozzles onto the leaves, and dirt and impurities adhering to the surface of the leaves can be flushed away.

[0013] Preferably, the guide plates are interconnected through connecting holes and fixing holes, and the sleeve plate is fixed to the back of the guide plate, and the fixing holes are distributed at equal angles on the sleeve plate. At the same time, the fixing holes and the connecting holes are arranged one by one, and the liquid in the fixed cylinder can be transmitted to the inside of the guide plate through the through grooves, fixing holes and connecting holes.

[0014] Preferably, a fixing tube passes through the interior of the sleeve, and a through groove is provided at one end of the fixing tube close to the sleeve. The through groove is an arc-shaped structure, and the arc length of the through groove is 1 / 4 of the circumference. At the same time, the distance between the through groove and the center of the transmission shaft is equal to the distance between the fixing hole and the center of the transmission shaft.

[0015] Preferably, the end of the fixed cylinder rotates in contact with the inner wall of the sleeve plate, and the fixed cylinder is fixedly inserted into the frame, and the fixed cylinder and the transmission shaft are rotationally connected, the guide plate and the sleeve plate rotate synchronously, and the fixed cylinder remains stationary, so the guide plate can only be connected to the liquid when it rotates from a horizontal state to a vertical state.

[0016] Preferably, the side of the fixed cylinder is connected to the interior of the water tank through a water pipe, and a turbine is installed inside the water tank, and the turbine is fixedly sleeved on the outside of the connecting shaft. When the turbine rotates, the liquid in the water tank can be transferred to the fixed cylinder through the water pipe.

[0017] Preferably, the recovery component includes a filter screen arranged on the inner side of the baffle, and a through hole is opened at the lower edge of the baffle, and a reflux hole is reserved on the conveyor belt at the bottom of the baffle, and the reflux holes are distributed at equal intervals. When the conveyor belt transports the vegetable leaves, the residual moisture on the leaves can fall on the conveyor belt and flow to the reflux holes through the through holes on the conveyor belt.

[0018] Preferably, a water receiving box is fitted on the lower surface of the conveyor belt, and the water receiving box is fixed on the inner side of the frame, and the bottom of the water receiving box is connected to the inside of the water storage tank through a connecting pipe, and the sediment in the excess water can be intercepted by the filter, and the water can flow to the water receiving box through the reflux hole and flow back to the water storage tank through the connecting pipe.

[0019] Preferably, a movable shaft is fixed to the end of the connecting shaft away from the motor, and a guide rod is fixed to the end of the movable shaft, and the two movable shafts are connected to each other by a pulley mechanism. At the same time, the guide rod is made of rubber. When the connecting shaft rotates, the guide rod can be driven to rotate synchronously through the movable shaft, and the guide rod can be driven to knock the conveyor belt to cause it to vibrate underneath.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the washing and decontamination vegetable leaf harvester can simultaneously wash away the dirt and impurities on the vegetable leaves by liquid washing while harvesting, and does not need to be washed centrally after harvesting, thus saving time. Moreover, after washing, the excess water on the vegetable leaves can be removed, thus avoiding the phenomenon of a large amount of water remaining and the accumulation of vegetable leaves causing damage and rot. The specific contents are as follows:

[0021] 1. The motor can also drive the turbine to rotate synchronously through the connecting shaft, and then the liquid in the water tank is transmitted to the fixed cylinder through the water pipe, and then transmitted to the cavity in the guide plate through the through groove, the fixing hole and the connecting hole, and finally can be sprayed out from the spray nozzle and sprayed on the leaves to wash them;

[0022] Furthermore, since the guide plate and the sleeve plate can rotate, while the fixed cylinder is in a stationary state, and the through groove is an arc-shaped structure, the liquid can enter the guide plate from the through groove only when the guide plate rotates from a horizontal state to a vertical state, and the liquid will not enter when the guide plate is at other angles, thereby reducing the waste of water resources and ensuring efficient washing of the vegetable leaves;

[0023] 2. During the transmission process, the residual water on the leaves can fall on the conveyor belt. The liquid flows downward through the inclined conveyor belt and flows into the inside of the baffle through the through holes on the baffle bar, and then flows into the water receiving box through the reflux hole. When the liquid flows into the inside of the baffle bar, it can be filtered through the filter screen to intercept the sediment in the liquid. Then, the liquid entering the water receiving box can be transmitted to the water storage tank through the connecting pipe to realize the liquid recycling;

[0024] Furthermore, when the connecting shaft rotates, it can drive the guide rod to rotate synchronously through the movable shaft, so that the guide rod can contact the bottom of the conveyor belt and knock it when rotating. The vibration generated in this way can shake off the mud and sand intercepted by the filter, thereby improving the cleanliness of the conveyor belt and facilitating the subsequent continuous transportation of vegetable leaves.

DETAILED DESCRIPTION

[0038] 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.

[0039] See also Figure 1-Figure 12 , the present invention provides the following technical solutions:

[0040] Embodiment 1: In order to solve the problems existing in the prior art, the present embodiment adopts the following technical scheme: a flushing and decontamination vegetable leaf harvester, which is provided with a frame 1, a receiving plate 2 is fixed at the left end of the frame 1, and a cutter is provided at the left end edge of the receiving plate 2, a conveyor belt 3 is installed on the inner side of the frame 1, and guard bars 4 are fixed at equal intervals on the surface of the conveyor belt 3; it includes: a motor 5, which is installed on the outer side of the frame 1, the output shaft of the motor 5 is connected to a connecting shaft 6, and the outer side of the connecting shaft 6 is connected to the end of the transmission shaft 7 through a pulley mechanism, a guide plate 8 is fixed to the outer side of the transmission shaft 7, and the guide plates 8 are distributed at equal angles on the transmission shaft 7, and the edge of the guide plate 8 away from the transmission shaft 7 is an arc structure; a flushing mechanism is arranged on the guide On the plate 8, the flushing mechanism is connected to the water tank 10, and the water tank 10 is fixed to the outside of the frame 1; the recovery component is arranged on the inner side of the conveyor belt 3, and the recovery component is also connected to the water tank 10; first, the frame 1 is a part of the harvester, and the harvester drives the receiving plate 2 forward during the forward movement, and the cutting knife at the front end of the receiving plate 2 can cut off the vegetable leaves, and then the vegetable leaves fall on the receiving plate 2. When the motor 5 drives the connecting shaft 6 to rotate, the transmission shaft 7 can be driven to rotate synchronously through the pulley mechanism, and then the guide plate 8 is driven to rotate, and the cut vegetable leaves are transmitted to the conveyor belt 3. During the guiding process, the vegetable leaves are rinsed by spraying liquid, and the conveyor belt 3 drives the vegetable leaves to be transmitted upward for collection. During the transmission process, the excess water on the vegetable leaves can be cleaned synchronously.

[0041] Most existing harvesters do not have a structure for cleaning the leaves when harvesting them. Usually, they need to be rinsed centrally after harvesting, which not only prolongs the entire harvesting time but also reduces the freshness of the leaves. Alternatively, the leaves are cleaned by vibration, which is not clean enough. Figure 1-Figure 8 As shown, the flushing mechanism includes spray nozzles 17 fixed at equal intervals at the edge of the guide plate 8, and the guide plate 8 is hollow, and a connecting hole 16 is reserved on the back of the guide plate 8; the guide plate 8 is connected to the fixing hole 15 through the connecting hole 16, and the sleeve 14 is fixed to the back of the guide plate 8, and the fixing holes 15 are distributed at equal angles on the sleeve 14, and the fixing holes 15 and the connecting holes 16 are arranged one by one; the interior of the sleeve 14 is penetrated by a fixing cylinder 12, and the fixing cylinder 1 A through slot 13 is provided at one end close to the sleeve plate 14. The through slot 13 is an arc-shaped structure, and the arc length of the through slot 13 is 1 / 4 of the circumference. At the same time, the distance between the through slot 13 and the center of the transmission shaft 7 is equal to the distance between the fixing hole 15 and the center of the transmission shaft 7. The end of the fixing cylinder 12 is fitted and rotated with the inner wall of the sleeve plate 14, and the fixing cylinder 12 is fixedly inserted into the frame 1, and the fixing cylinder 12 and the transmission shaft 7 are rotatably connected. The side of the fixing cylinder 12 is connected to the inside of the water storage tank 10 through the water delivery pipe 11. The two water tanks 10 are interconnected, and a turbine 9 is installed inside the water tank 10, and the turbine 9 is fixedly sleeved on the outer side of the connecting shaft 6; when the vegetable leaves fall on the receiving plate 2, the guide plate 8 is driven to rotate by the transmission shaft 7 to transmit the vegetable leaves on the receiving plate 2 to the conveyor belt 3. While the motor 5 is driven, the turbine 9 can also be driven to rotate synchronously through the connecting shaft 6, so that the liquid in the water tank 10 is transmitted to the fixed cylinder 12 through the water pipe 11, and then transmitted to the cavity in the guide plate 8 through the through groove 13, the fixed hole 15 and the connecting hole 16, and finally can be sprayed from the spray nozzle 17 to spray on the vegetable leaves for washing. Since the guide plate 8 and the sleeve plate 14 can rotate, and the fixed cylinder 12 is in a stationary state, the through groove 13 is an arc-shaped structure. Therefore, only when the guide plate 8 rotates from a horizontal state to a vertical state, the liquid can enter the guide plate 8 from the through groove 13. When the guide plate 8 is at other angles, the liquid will not enter, thereby reducing the waste of water resources and ensuring efficient washing of the vegetable leaves.

[0042] Embodiment 2: Some existing harvesters use liquid flushing to clean, and a large amount of liquid remains on the surface of the leaves after cleaning. There is a lack of a structure to remove excess water, which leads to subsequent accumulation and rotting of leaves. Therefore, this embodiment adopts the following technical solutions, such as Figure 1 and Figure 9-12As shown, the recovery component includes a filter screen 18 arranged on the inner side of the baffle 4, and a through hole is opened at the lower edge of the baffle 4, and a return hole 19 is reserved on the conveyor belt 3 at the bottom of the baffle 4, and the return holes 19 are distributed at equal intervals; a water receiving box 20 is fitted on the lower surface of the conveyor belt 3, and the water receiving box 20 is fixed to the inner side of the frame 1, and the bottom of the water receiving box 20 is connected to the inside of the water storage tank 10 through a connecting pipe 21; a movable shaft 22 is fixed at the end of the connecting shaft 6 away from the motor 5, and a guide rod 23 is fixed at the end of the movable shaft 22, and the two movable shafts 22 are connected to each other through a pulley mechanism, and the guide rod 23 is made of rubber; the vegetable leaves guided by the guide plate 8 are transmitted on the conveyor belt 3, and the residual water on the vegetable leaves during the transmission process can fall on the conveyor belt 3, and the water on the vegetable leaves can fall on the conveyor belt 3. The inclined conveyor belt 3 allows the liquid to flow downward and flow into the interior of the baffle 4 through the through holes on the baffle 4, and then flow into the water receiving box 20 through the reflux hole 19. When the liquid flows into the interior of the baffle 4, it can be filtered through the filter screen 18 to intercept the mud and sand in the liquid. Then the liquid entering the water receiving box 20 can be transmitted to the water storage tank 10 through the connecting pipe 21, so that the liquid is recycled and water resources are saved. When the connecting shaft 6 rotates, the guide rod 23 can be driven to rotate synchronously through the movable shaft 22. The two movable shafts 22 are driven by a pulley mechanism, so that the guide rod 23 can contact and knock the bottom of the conveyor belt 3 when rotating. The vibration generated in this way can shake off the mud and sand intercepted by the filter screen 18, thereby improving the cleanliness of the conveyor belt 3, so as to facilitate the subsequent continuous transportation of vegetable leaves.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
