Novel efficient potato harvester

Abstract

The utility model provides a novel efficient potato harvester which comprises a machine frame, a transmission shaft, a first rotating shaft, a first driven shaft, a first conveying belt, a second rotating shaft, a second driven shaft and a second conveying belt. And limiting in the axis direction of the connecting disc is achieved under the limiting and stopping effect of the limiting plate, it can be guaranteed that the second conveying belt can move downwards to the middle of the connecting disc along the inclined face of the limiting plate when the second conveying belt deviates or breaks away from the connecting disc, and therefore the situation that when potatoes fall on the second conveying belt after being conveyed from the first conveying belt, the potatoes are damaged is avoided. Due to the fact that the impact on the second conveying belt is too large due to the gravity action of the potatoes, the transmission connection stability is reduced, and it is guaranteed that the potato harvester can efficiently complete the harvesting action while running stably.

Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a new type of high-efficiency potato harvester. Background Art

[0002] A potato harvester is a kind of agricultural machinery and equipment specifically used for harvesting potatoes. They are designed to quickly and efficiently harvest potatoes in potato planting fields to improve productivity, reduce labor costs, and ensure the quality of harvested potatoes. Its main component groups are:

[0003] Digging system: Potato harvesters are usually equipped with a digging system for digging potatoes out of the soil. These systems usually consist of rotating digging knives or digging claws, which can smoothly dig out potato tubers.

[0004] Conveying system: The dug-out potatoes are conveyed to the rear of the machine, and through a conveyor belt or other devices, the potatoes are transferred from the digging position to a collection container or a subsequent processing unit.

[0005] Sorting system: Some advanced potato harvesters may be equipped with a sorting system for classifying and sorting potatoes after they are dug out. This helps to remove defective or unqualified potatoes, thereby improving the harvest quality.

[0006] Cleaning system: After harvesting, potatoes usually need to be cleaned to remove soil and impurities. Therefore, some harvesters are equipped with a cleaning system, such as a water spray or a rotating brush, for cleaning the surface of potatoes.

[0007] Collection container: The harvested potatoes will ultimately be conveyed into a collection container, which can be a collection box, a baffle, or other forms of containers for collecting and storing potatoes, facilitating subsequent processing and transportation.

[0008] Currently, it is usually carried out in a double-layer conveying manner during the conveying process. Among them, the first-layer conveying located above screens and picks out potatoes from the land, and after transmission, they fall to the second layer for conveying. The peeling of the surface soil blocks can be realized through the falling and the collision between potatoes. However, when the potatoes fall from the first layer to the second-layer conveying, due to their own gravity, it will impact the conveyor belt, thereby affecting the connection stability of the conveyor belt on the rotating shaft, causing deviation or detachment, and further reducing the stability of the subsequent conveying. Content of the Utility Model

[0009] In view of this, the technical problem to be solved by the utility model is: how to provide a new type of high-efficiency potato harvester to improve the connection stability of the conveyor belt when it is impacted by the gravity of potatoes.

[0011] The transmission shaft is arranged on the frame, and the end of the transmission shaft is connected to the end of the first rotating shaft by a belt. The transmission shaft transmits the power from the power component to the first rotating shaft through the belt;

[0012] Both ends of the first rotating shaft are rotatably connected to the frame, and both ends of the first driven shaft are rotatably connected to the frame. The first conveyor belt is connected between the first rotating shaft and the first driven shaft, and the first rotating shaft is arranged above the first driven shaft;

[0013] Both ends of the second rotating shaft are rotatably connected to the frame, and both ends of the second driven shaft are rotatably connected to the frame. The second conveyor belt is connected between the second rotating shaft and the second driven shaft, the second rotating shaft is arranged above the second driven shaft, and the second driven shaft is arranged below the first rotating shaft;

[0014] Connection discs are respectively arranged at both ends of the second rotating shaft and the second driven shaft, and the second conveyor belt is sleeved and connected to the connection discs. Wherein, limiting plates are arranged at both ends of the connection discs, the second conveyor belt is located between the two limiting plates on the connection discs, the opposite surfaces of the two limiting plates are inclined surfaces and are inclined towards the middle position of the connection discs, and the included angle between the opposite surfaces of the two limiting plates and the axis of the connection discs is an acute angle.

[0015] Further, the distance between the axis of the first rotating shaft and the axis of the first driven shaft is greater than the distance between the axis of the second rotating shaft and the axis of the second driven shaft.

[0016] Further, the transmission shaft is parallel to the first rotating shaft and the second rotating shaft.

[0017] Further, the range of the included angle between the opposite surfaces of the two limiting plates and the axis of the connection discs is 50° - 75°.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figures 1-4 As shown, the utility model provides a novel high-efficiency potato harvester, which includes a frame 11, a transmission shaft 12, a first rotating shaft 21, a first driven shaft 22, a first conveyor belt 23, a second rotating shaft 31, a second driven shaft 32, and a second conveyor belt 33.

[0025] The transmission shaft 12 is arranged on the frame 11. The end of the transmission shaft 12 is connected to the end of the first rotating shaft 21 by a belt. The transmission shaft 12 transmits the power conveyed by the power component to the first rotating shaft 21 through the belt. The transmission shaft 12 is arranged in parallel with the first rotating shaft 21 and the second rotating shaft 31. Specifically, at the rear side of the frame 11, that is, near the conveying end of the second conveyor belt 33, a storage chamber is arranged to realize the harvesting, accommodation and storage of the potatoes conveyed by the second conveyor belt 33.

[0026] Both ends of the first rotating shaft 21 are respectively rotatably connected to the frame 11. Both ends of the first driven shaft 22 are respectively rotatably connected to the frame 11. A first conveyor belt 23 is connected between the first rotating shaft 21 and the first driven shaft 22. The first rotating shaft 21 is arranged above the first driven shaft 22.

[0027] Both ends of the second rotating shaft 31 are respectively rotatably connected to the frame 11. Both ends of the second driven shaft 32 are respectively rotatably connected to the frame 11. A second conveyor belt 33 is connected between the second rotating shaft 31 and the second driven shaft 32. The second rotating shaft 31 is arranged above the second driven shaft 32. The second driven shaft 32 is arranged below the first rotating shaft 21.

[0028] The distance dimension between the axis of the first rotating shaft 21 and the axis of the first driven shaft 22 is greater than the distance dimension between the axis of the second rotating shaft 31 and the axis of the second driven shaft 32. Thus, it is ensured that the length of the first conveyor belt 23 is greater than the length of the second conveyor belt 33, and the conveying length of the potatoes at the front end is increased.

[0029] Connection disks 34 are respectively arranged at both ends of the second rotating shaft 31 and the second driven shaft 32. The second conveyor belt 33 is sleeved and connected to the connection disks 34. Among them, limit plates 35 are arranged at both ends of the connection disk 34. The second conveyor belt 33 is located between the two limit plates 35 on the connection disk 34.

[0030] The opposite surfaces of the two limit plates 35 are inclined planes and are inclined towards the middle position of the connection disk 34. The included angle between the opposite surfaces of the two limit plates 35 and the axis of the connection disk 34 is an acute angle. The range of the included angle between the opposite surfaces of the two limit plates 35 and the axis of the connection disk 34 is 50° - 75°.

[0031] The second conveyor belt 33 is used to receive the potatoes conveyed by the first conveyor belt 23. The second conveyor belt 33 is driven by the second rotating shaft 31 and the second driven shaft 32 to operate. Connection disks 34 are respectively arranged at the end parts of the second rotating shaft 31 and the second driven shaft 32. Limit plates 35 are respectively arranged at both ends of the connection disk 34. The opposite surfaces of the limit plates 35 at both ends are inclined planes and are arranged at an acute angle with respect to the axis of the connection disk 34.

[0032] Since the second conveyor belt 33 is sleeved on the connecting disk 34 and is limited in the axial direction of the connecting disk 34 under the limiting and blocking action of the limiting plate 35, it can be ensured that when the second conveyor belt 33 deviates or disengages from the connecting disk 34, it can move downward along the inclined surface of the limiting plate 35 to the middle of the connecting disk 34. Thus, when the potatoes are conveyed from the first conveyor belt 23 and fall on the second conveyor belt 33, the reduction of the transmission connection stability caused by the excessive impact on the second conveyor belt 33 due to the gravity of the potatoes can be prevented, and it is ensured that the potato harvester can efficiently complete the harvesting action while operating stably.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
