Description

Technical Field

[0001] The present invention relates to the technical field of potato harvesting, and in particular to a potato conveying component, a potato harvester and a potato harvesting method. Background Art

[0002] Potatoes are one of the important economic crops in my country. Since potatoes grow under the soil and have tubers, they are usually harvested manually. However, the manual harvesting method is inefficient and it is difficult to improve the harvesting efficiency.

[0003] With the development of science and technology, a variety of potato harvesting devices have appeared on the market in recent years. Compared with manual harvesting methods, the use of potato harvesting devices to harvest potatoes has reduced the labor intensity of potato farmers to a certain extent and improved the efficiency of potato harvesting.

[0004] However, the current potato harvesting devices still have some deficiencies. Some potato harvesting devices still pile the potatoes on the ground after shoveling up the soil and potatoes, and still require manual labor to pick up the potatoes with a vehicle, and the degree of mechanization is low. On the other hand, some potato harvesting devices still have a lot of soil attached to the surface of the potatoes when shoveling up the soil and potatoes and conveying the potatoes. One reason for this is that when the potatoes are conveyed, the potatoes remain stationary relative to the part on the conveyor belt with which they are in contact, making it difficult to clean the soil adhered to the surface of the potatoes, thereby making the soil content in the collected potatoes high, which is not conducive to potato demuding.

[0005] Therefore, based on the above-mentioned deficiencies, there is an urgent need to design a potato conveying assembly, a potato harvester and a potato harvesting method so as to reduce the soil content in the collected potatoes and improve the convenience of collection. Summary of the Invention

[0006] The object of the present invention is to address the shortcomings of current potato harvesting methods and provide a potato conveying assembly, a potato harvester and a potato harvesting method so as to reduce the soil content in the collected potatoes and improve the convenience of collection.

[0007] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0008] A potato conveying assembly includes a potato conveying chain, a collecting cage and a potato receiving plate;

[0009] The potato conveyor chain is used to convey potatoes scooped from the soil to the bottom of the collection cage via the potato conveyor chain; the collection cage lifts the potatoes at its bottom by rotating, and under the action of gravity, the lifted potatoes in the collection cage fall onto the potato receiving plate; the potato receiving plate is used to cooperate with the tipping bucket, so that the potatoes fall onto the potato receiving plate and are collected by the tipping bucket;

[0010] The potato conveyor chain is provided with a plurality of gaps for separating potatoes from soil, so that the soil passes through the gaps and escapes from the potato conveyor chain; the collecting cage is hollow, and soil can fall out of the collecting cage when the collecting cage rotates.

[0011] As the preferred technical solution of this application, the potato conveyor chain is a chain conveyor, and the potato conveyor chain includes a plurality of baffles, the plurality of baffles are parallel, and the arrangement direction of the plurality of baffles is parallel to the length direction of the baffles, the baffles are used to contact and convey potatoes, and the gaps are formed between adjacent baffles.

[0012] As the preferred technical solution of this application, a brush tube is provided on the baffle bar, and a plurality of bristles are fixedly provided on the outer side of the brush tube. The plurality of bristles are arranged around the outer side of the brush tube, and in the direction around the central axis of the baffle bar, the brush tube is fixed relative to the baffle bar, and the bristles on the brush tubes on adjacent baffle bars can contact each other.

[0013] As the preferred technical solution of this application, a spring is provided on the baffle, which is elastic and is used to cooperate with the brush cylinder. The potato conveying chain is equipped with a baffle, which is used to cooperate with the brush cylinder. When the potato conveying chain conveys potatoes, the baffle is against the brush cylinder, causing the brush cylinder to move along the length direction of the baffle, and the spring is used to reset the brush cylinder.

[0014] As a preferred technical solution of this application, the baffle is S-shaped and wavy. When the potato conveyor chain conveys potatoes, the baffle abuts against the brush cylinder, causing the brush cylinder to move back and forth along the length direction of the baffle bar.

[0015] As the preferred technical solution of this application, the brush cylinder includes a brush cylinder body and a contact piece, the bristles are arranged on the brush cylinder body, the contact piece is fixed to the brush cylinder body, the contact piece is rod-shaped, and the contact piece is used to abut against the baffle, so that when the potato conveyor chain conveys potatoes, the contact piece guides the brush cylinder body to move along the length direction of the baffle.

[0016] As a preferred technical solution of this application, the potato conveying chain further comprises a sprocket and a chain, the baffle being fixed on the chain, the sprocket being engaged with the baffle, or the sprocket being engaged with the chain, and the rotation of the sprocket being used to move the baffle to convey potatoes.

[0017] As the preferred technical solution of this application, a plurality of partitions are provided in the collection cage, and the plurality of partitions are arranged circumferentially along the inner wall of the collection cage, and the length direction of the partitions is parallel to the central axis of the collection cage. The partitions are used to transport the potatoes located at the bottom of the collection cage to the upper part of the collection cage when the collection cage rotates. After the potatoes reach the upper part of the collection cage, the potatoes raised in the collection cage fall onto the potato receiving plate under the action of gravity.

[0018] A potato harvester comprises the potato conveying assembly as described above, and also comprises a frame, a knife plate and the tipping bucket. The knife plate, potato conveying assembly and tipping bucket are all arranged on the frame. The knife plate is used to be placed underground to scoop up soil and potatoes and transport them to the potato conveyor chain.

[0019] A potato harvesting method, using the potato harvester as described above to harvest potatoes, comprises the following steps:

[0020] S1: turning the soil, placing the blade into the ground, moving the blade forward to scoop up the soil and potatoes and transporting the soil and potatoes to the potato conveyor chain;

[0021] S2 cleaning and transportation: the potato conveyor chain separates the potatoes from the soil and conveys the potatoes to the collecting cage. The collecting cage lifts the potatoes at the bottom by rotating, and under the action of gravity, the lifted potatoes in the collecting cage fall onto the potato receiving plate.

[0022] S3 is collecting and packing, the potatoes dropped onto the potato receiving plate slide into the tipping bucket for collection, and after the tipping bucket collects the potatoes slowly, the tipping bucket partition is opened and the potatoes are put into bags or other storage tools.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] In the solution of the present application, the potato conveying assembly includes a potato conveyor chain, a collecting cage and a potato receiving plate. The potatoes scooped from the soil are conveyed to the bottom of the collecting cage via the potato conveyor chain. In the process of the potato conveyor chain conveying the potatoes, the gaps on the conveyor chain allow the potatoes and the soil to be separated, thereby reducing the soil mixed with the potatoes conveyed to the collecting cage, screening the potatoes and the soil, and the collecting cage lifts the potatoes at its bottom by rotating, while collecting the potatoes. The cage is hollow, so that when the potatoes are lifted, they roll and the potatoes in contact easily rub against each other, which facilitates the separation of soil attached to the potatoes from the potatoes. The potatoes are further screened, and the separated soil can fall through the hollow structure of the collection cage. This not only facilitates the transportation of potatoes from low to high places and facilitates bagging, thus avoiding manual picking up, but also further reduces the amount of soil mixed in the potatoes, which is beneficial for potato desludging and collection.

[0025] Furthermore, by providing a brush cylinder, and a plurality of bristles are fixedly provided on the outer side of the brush cylinder, the bristles are arranged around the outer side of the brush cylinder, and at the same time, in the direction of the central axis of the baffle, the brush cylinder is fixed relative to the baffle, so that the brush cylinder will not rotate around the central axis of the baffle. On the one hand, the provision of the brush cylinder increases the friction between the potatoes and the potato conveyor chain when they are in contact, and when the potato conveyor chain is tilted, it can improve the stability when conveying potatoes. On the other hand, in the process of conveying potatoes, on the baffle contacted by the potatoes, some soil can pass through the bristles between the brush cylinders on adjacent baffles, and some soil is stuck on the bristles between the brush cylinders on adjacent baffles. As the potato conveyor chain rotates periodically, in the process of changing the movement direction of the baffle, for example, in the process of changing the movement direction of the baffle from left to right, when the baffle changes direction, The brush rolls are used to pull the dirt from the conveyor belt and to remove the dirt stuck in the conveyor belt, thereby cleaning the dirt.

[0026] Furthermore, an elastic spring is provided on the baffle, and the spring is used to cooperate with the brush cylinder, so that one end of the spring is against the brush cylinder, and the other end of the brush cylinder is against the baffle. At the same time, the potato conveying chain is equipped with a baffle, so that when the potato conveying chain conveys potatoes, when the baffle moves, the baffle is against the moving brush cylinder, so that the brush cylinder moves along the length direction of the baffle, and at the same time, under the action of the spring, the brush cylinder is reset. In this process, the brush cylinder moves along the length direction of the baffle, so that the bristles on the brush cylinder are hung on the soil and the bottom of the potatoes, which is convenient for crushing large pieces of soil and also convenient for scraping off the soil attached to the potatoes, thereby facilitating the crushed soil to fall from the gap and facilitating the separation of the soil from the potatoes.

[0027] Furthermore, the baffle is arranged in an S-shaped wave shape, so that when the potato conveyor chain conveys potatoes, in the process of the brush cylinder moving with the baffle bar, when the baffle plate and the brush cylinder are in contact with each other, the brush cylinder can move back and forth along the length direction of the baffle bar, and at the same time, the brush cylinders on adjacent baffle bars can move relative to each other, further improving the scraping effect of the bristles on the brush cylinder on the soil and potatoes, facilitating the separation of the soil and potatoes, and at the same time reducing the soil stuck in the gap, thereby improving the passing rate of the soil through the gap;

[0028] In another embodiment of the present application, a potato harvester is provided, comprising a potato conveying assembly, a frame, a blade, and a dump bucket, wherein the blade, potato conveying assembly, and dump bucket are all arranged on the frame. When harvesting potatoes, the blade is placed underground. Simultaneously, the potato harvester is towed by a tractor or other traction device, causing the blade placed underground to move, thereby scooping up soil and potatoes and transporting them to a potato conveyor chain. After the potatoes pass through the potato conveying assembly, the potatoes are separated from the soil, and potatoes in a low position are transported to a high position. The potatoes are then collected in the dump bucket, which facilitates soil cleaning and potato collection.

[0029] In another embodiment of the present application, a potato harvesting method is provided, in which potatoes are harvested using a potato harvester, which includes steps S1: turning over the soil, S2: cleaning and transportation, and S3: collecting and packaging. This method facilitates the separation of potatoes from soil and facilitates the harvest of potatoes containing less soil. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Example 1: See Figure 1-8 As shown,

[0047] This embodiment provides a potato conveying assembly 1, comprising a potato conveying chain 2, a collecting cage 3 and a potato receiving plate 4;

[0048] The potato conveyor chain 2 is used to convey potatoes scooped from the soil to the bottom of the collecting cage 3 via the potato conveyor chain 2; the collecting cage 3 lifts the potatoes at its bottom by rotating, and under the action of gravity, the lifted potatoes in the collecting cage 3 fall onto the potato receiving plate 4; the potato receiving plate 4 is used to cooperate with the tipping bucket 5, so that the potatoes fall onto the potato receiving plate 4 and are collected by the tipping bucket 5;

[0049] In addition, a plurality of gaps 7 are provided on the potato conveyor chain 2, and the gaps 7 are used to separate potatoes and soil, so that the soil passes through the gaps 7 and escapes from the potato conveyor chain 2; the collecting cage 3 is hollow, and soil can fall out of the collecting cage 3 when the collecting cage 3 rotates.

[0050] In the present application, the potato conveying assembly 1 includes a potato conveyor chain 2, a collecting cage 3 and a potato receiving plate 4. The potatoes scooped from the soil are conveyed to the bottom of the collecting cage 3 through the potato conveyor chain 2. In the process of conveying potatoes by the potato conveyor chain 2, the gaps 7 on the conveyor chain allow the potatoes and the soil to be separated, thereby reducing the soil mixed with the potatoes conveyed to the collecting cage 3. The collecting cage 3 lifts the potatoes at its bottom by rotating, and at the same time The collecting cage 3 is hollow, so that the potatoes roll during the process of being lifted, and the potatoes in contact are easily rubbed against each other, which facilitates the separation of soil attached to the potatoes from the potatoes. At the same time, the separated soil can fall from the hollow structure on the collecting cage 3, which is not only conducive to transporting potatoes from a low place to a high place and facilitating bagging and packaging, thereby avoiding manual picking up, but also further reduces the soil mixed in the potatoes, which is beneficial to the demuding and collection of potatoes.

[0051] As a preferred embodiment, on the basis of the above-mentioned method, further, the potato conveyor chain 2 is a chain conveyor, and the potato conveyor chain 2 includes a plurality of baffles 6, the plurality of baffles 6 are parallel, and the arrangement direction of the plurality of baffles 6 is parallel to the length direction of the baffles 6, the baffles 6 are used to contact and convey potatoes, and the gaps 7 are formed between adjacent baffles 6.

[0052] Furthermore, the potato conveyor chain 2 is a chain conveyor, and the potato conveyor chain 2 includes a plurality of bars 6. The gaps formed by adjacent bars 6 allow soil to pass through, and potatoes can be conveyed on the bars 6, thereby facilitating the separation of soil and reducing the soil contained in the conveyed potatoes.

[0053] Example 2: See Figure 1-8 As shown,

[0054] On the basis of the technical solution of Example 1, further, a brush tube 8 is provided on the baffle 6, and a plurality of bristles 9 are fixedly provided on the outer side of the brush tube 8.

[0055] Furthermore, by providing a brush barrel 8, and a plurality of bristles 9 are fixedly provided on the outer side of the brush barrel 8, the bristles 9 are arranged around the outer side of the brush barrel 8, and at the same time, in the direction of the central axis of the baffle 11, the brush barrel 8 is fixed relative to the baffle 6, so that the brush barrel 8 will not rotate around the central axis of the baffle 6. On the one hand, the provision of the brush barrel 8 increases the friction force when the potatoes contact the potato conveyor chain 2, and when the potato conveyor chain 2 is tilted, it can improve the stability when conveying potatoes. On the other hand, in the process of conveying potatoes, on the baffle 6 contacted by the potatoes, some soil can pass through the bristles 8 on the adjacent baffles 6, and some soil is stuck on the bristles 9 between the brush barrels 8 on the adjacent baffles 6. As the potato conveyor chain 2 rotates periodically, in the process of changing the movement direction of the baffle 6, for example, in the process of changing the movement direction of the baffle 6 from left to right, When the brush 8 is moved, the dirt stuck in the bristles 9 is stirred, so as to clean the dirt on the bristles 9 between the brush cylinders 8 on the adjacent bristles 6. At the same time, after the movement direction of the bristles 6 is changed, the dirt is transferred from the upper side of the potato conveyor chain 2 to the lower side of the potato conveyor chain 2, so that part of the dirt falls from the bristles 9 under the action of gravity. In the present application, the setting of the brush cylinder 8 can not only make the dirt fall from the gap 7, but also clean the dirt stuck in the gap 7, so that the potato conveyor chain 2 can reduce the accumulation of dirt on the potato conveyor chain 2 when it works for a long time, reduce the cleaning work of the dirt on the potato conveyor chain 2 in the later period, and enhance the friction when the potatoes contact the potato conveyor chain 2, thereby improving the stability during transportation.
