Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to an anti-entanglement picking device and a harvester. Background Art

[0002] my country is a major sugar producer in the world. With the development of the sugar industry, the market demand for sugarcane, the main raw material of the sugar industry, has also been increasing. For a long time, an obvious weak link in domestic sugarcane mechanization has been the mechanization of the harvesting process, resulting in high sugarcane production costs and low international competitiveness of my country's sugar industry. In addition, in recent years, domestic labor costs have continued to rise, which has seriously threatened the healthy and sustainable development of my country's sugar industry. Therefore, the mechanization of sugarcane harvesting has become imperative.

[0003] At present, the technology development of sugarcane harvesters at home and abroad is in its early stages, and there are still some problems, including unstable speed of the walking system, high rate of broken sugarcane heads during harvesting, high impurity rate of sugarcane leaves during stripping, and sugarcane loss rate. The blockage of the sugarcane harvester channel by sugarcane leaves is a difficult problem in the design and manufacture of sugarcane harvesters. In addition, the sugarcane loss rate is also one of the difficulties in the design and manufacture of sugarcane harvesters. After the sugarcane is harvested mechanically, the unfed and fallen sugarcane is scattered in the field. If the sugarcane is harvested mechanically, the sugarcane will be scattered in the field. Manual collection of scattered sugarcane is not only labor-intensive but also has low collection efficiency. In addition, the cut sugarcane has many cuts and needs to be sent to the sugar factory for sugar extraction in a short time. Otherwise, the sugarcane will become moldy and affect the quality of the sugar. At the same time, since sugarcane is not a fine crop and there are many weeds in the fields, when using a machine to pick it up, the function of the picking roller is to pull the sugarcane in and transport it upwards. When working, it is close to the ground and is very easy to get dust, soil and grass, causing grass entanglement. In addition, the long sugarcane leaves are also prone to grass entanglement, which shortens the service life of the machine's operating parts.

[0004] Currently, there are technologies that improve the structure of floating rollers to prevent debris, dirt, minerals, and plant residues from entering the area where the mechanism responsible for rotating these rollers is installed. For example, patent CN112293060A uses sealing elements to prevent debris, dirt, minerals, and plant residues from entering the roller rotation mechanism. However, this technology does not have an anti-entanglement function and is targeted at floating rollers rather than pick-up rollers. Currently, there are also technologies that reduce grass entanglement by increasing the rotation radius. However, due to structural and functional limitations, these structural improvements have limited anti-entanglement effects and are less effective against long weeds and sugarcane leaves. In addition, their complex structures are difficult to clean and maintain, which is labor-intensive and affects harvesting efficiency. Summary of the Invention

[0040] like Figure 5As shown, the picking roller welded part 2 includes a picking toothed strip 25, a picking end plate 24, a first roller 22, a second roller 23, a picking tube welding part 21 and a toothed strip 26; the first roller 22 and the second roller 23 are connected through the picking tube welding part 21, the first roller 22 is welded close to the shaft end of the picking tube welding part 21, and the second roller 23 is welded at the other end; the picking end plates 24 are respectively arranged at both ends of the picking roller welded part 2, and the picking end plates 24 are respectively connected and welded to the first roller 22 and the second roller 23; the picking toothed strip 25 is evenly welded Connect to the first roller 22, the second roller 23 and the picking cylinder welding part 21, weld a circle, the adjacent two picking tooth bars 25 are 120° apart, and the two ends of the picking tooth bar 25 are respectively welded to the picking end plate 24; after welding the picking tooth bars 25, weld the rack 26, and the rack 26 is evenly welded between the adjacent two picking tooth bars 25 (for example, the number of picking tooth bars 25 is three, and the number of racks 26 is also three); the picking end plate 24 at one end of the picking roller welding part 2 is connected to the right baffle 12 in the motor end baffle welding 1 through the oil seal 8.

[0042] Furthermore, in one embodiment, a motor cover 4 or a seal is included, and the motor cover 4 or the seal is arranged at the motor end; by installing the motor cover 4 at the motor end and sealing it with glue or sealing the motor end with a seal, grass and soil are prevented from entering the motor to achieve anti-entanglement; the motor cover 4 is shaped like the oil pipe at the rear end of the motor.

[0044] The left motor end baffle weldment 1 and the right bearing end baffle weldment 3 form a labyrinth-type anti-grass double-sealing structure with the picking-up roller weldment 2; after the machine is started, the picking-up roller is rotated by the picking motor to continuously pull the sugarcane in and transport it upwards. The added labyrinth-type anti-grass double-sealing structure allows the grass and soil that enter to be spit out through this structure, that is, after grass, soil, dust, etc. enter from the picking-up end plate, they are blocked by the double-sealing structure composed of the oil seal 8, the picking-up end plate 24, the left baffle plate 32 and the right baffle plate 12 to prevent soil from entering; and the left baffle plate 32 and the right baffle plate 12 rotate the grass and soil out during the continuous rotation of the picking-up roller; by installing the motor cover plate 4 at the motor end and sealing it with glue or by sealing the motor end with a seal, grass and soil are prevented from entering from the motor; by installing the bearing end cover plate on the bearing seat at the bearing end with bolts or directly buckling the dust cover into the bearing seat, grass and soil are prevented from entering from the bearing end, forming a complete set of anti-winding devices with complete sealing performance.

[0045] The present invention forms a complete set of anti-entanglement picking devices with complete sealing performance through a labyrinth-type anti-entanglement double sealing structure + a dust cover + an imitation motor cover, which effectively prevents problems such as soil, grass and dust from entering the picking roller during operation, reduces equipment failure rate, maintenance rate, after-sales cost and fuel consumption, increases the service life of corresponding components, and improves work efficiency.

[0046] The anti-entanglement picking device disclosed in the present invention can reduce the entry of dust, soil, weeds and the like into the picking drum, has an anti-entanglement function, and has a good anti-entanglement effect. It has a simple structure and is easy to manufacture and clean.

[0047] The anti-entanglement picking device disclosed in the present invention can reduce the entry of dust, soil, weeds, etc. into the picking drum, thereby reducing the maintenance time of the machine and extending the service life of the machine operating parts. For example, the service life of working parts such as bearings and motors responsible for the rotation of the drum is prolonged; there is no need to disassemble the lower drum to clean dust, soil, weeds, etc., thereby reducing the number of disassembly times and improving working efficiency; the anti-entanglement picking device liberates labor and imitates the process of picking crops by a manual fork. The rotation speed of the picking drum is relatively low, and the grab teeth can support the bottom of the crops and send them into the interior of the machine during operation, which has little impact on fragile crops and greatly reduces the fruit drop rate and loss rate of crops during the picking process.
