Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to an anti-jamming device for a cutting platform of an intelligent sugarcane cutting machine. Background Art

[0002] Currently, sugarcane seed preparation and cutting primarily relies on traditional manual cutting or fixed-length cutting equipment. Manual cutting is inefficient and labor-intensive, while fixed-length cutting methods can easily lead to problems such as cutting into sugarcane nodes, a high bud injury rate, uneven cuts, and easily damaged cuts. The uneven quality of the sugarcane segments significantly impacts the budding rate, directly affecting sugarcane production yields and revenues. Therefore, the development of intelligent sugarcane pre-cutting equipment using intelligent technology is essential for ensuring the quality of pre-cut sugarcane seeds, improving cutting efficiency, and selecting high-quality sugarcane seeds. This plays a significant role in ensuring increased sugarcane production yields and revenues. For example, Patent Publication No. CN 109168499 A discloses a sugarcane pre-cutting workstation comprising a sugarcane conveying device, a sugarcane node identification device, and a cutting device. The sugarcane cutting workstation uses the location of sugarcane nodes, as determined by a node recognition device, to adjust the cutting positions of the various cutting mechanisms, ensuring that the cuts avoid nodes and buds, enabling large-scale production of sugarcane pre-cutting. However, the sugarcane cutting platform currently suffers from a problem where the blades are prone to jamming after cutting and retracting, resulting in poor overall system operation and overall inefficiency, impacting the subsequent cutting process.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The anti-stuck device of the cutting platform of the sugarcane intelligent seed cutter of the present invention is provided with a push rod and a sugarcane guide groove, and the combination of the push rod and the sugarcane guide groove can effectively improve the problem of sugarcane jamming. In the process of the cutter, since the blade has a certain thickness, it will be inserted into the sugarcane segment as a whole when the blade cuts the whole sugarcane, and the sticky sugarcane segment will move together when the blade is retracted. The function of the push rod and the sugarcane guide groove is to push off the sugarcane segment stuck to the cutter after cutting when the cutter is retracted, so that it can fall smoothly from the sugarcane drop groove, and prevent it from being stuck in the sugarcane receiving groove and affecting the subsequent cutting process.

[0016] (2) The anti-stuck device of the present invention is provided with a photoelectric sensor above the sugarcane trough to detect whether there is sugarcane in the trough, so as to facilitate the normal operation of the cutting work, reduce the jamming caused by the sugarcane being in the trough but not being detected, and improve the continuity of the entire system.

[0017] (3) The anti-stuck device of the present invention is provided with a cutting table support directly behind the cutting table and on the movable cross bar. The cutting table support can effectively prevent the cutting table from being deformed and tilted backward due to long-term cutting work, thereby avoiding the phenomenon of being unable to completely cut the sugarcane caused by the deformation and tilting backward of the cutting table, and ensuring the long-term and efficient operation of the system.

DETAILED DESCRIPTION

[0023] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0024] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations such as "include" or "comprising", etc., will be understood to include the stated elements or components but not to exclude other elements or other components.

[0025] like Figures 1 to 3 As shown, according to a specific embodiment of the present invention, an anti-stuck device for a cutting platform of an intelligent sugarcane cutting machine is provided. The cutting platform includes a frame 1 and a plurality of cutting mechanisms 2, and each cutting mechanism 2 is provided with an anti-stuck device 3. Each cutting mechanism 2 includes a cylinder 21, a cylinder bracket 22, a cutter 23 and a cutting table 24. The cylinder bracket 22 is connected to the movable cross bar 28. A driving mechanism is provided below the cylinder bracket 22. The cylinder bracket 22 and the movable cross bar 28 are synchronously moved forward and backward on the frame 1 by the driving mechanism. The cylinder 21 is mounted on the cylinder bracket 22. A cutter 23 is mounted at the front end of the piston rod of the cylinder 21. A cutting table 24 is provided in front of the cutter 23. The cutting table 24 is provided on the movable cross bar 28. A sugarcane accommodating groove 25 is provided on the knife side of the cutting table 24. The sugarcane is placed horizontally in a sugarcane trough 25. During cutting, a cylinder 21 drives a cutter 23 toward a cutting platform 24, severing the sugarcane within the trough 25. Multiple seed cutting mechanisms 2 are provided, allowing the sugarcane to be cut into multiple sections. For details on the specific structure of the seed cutter, please refer to the applicant's prior patent application, publication number CN 109168499 A.

[0026] The anti-stuck device 3 comprises a push rod 31, a sugarcane guide trough 32, a photoelectric sensor group 33, a magnetic induction sensor group 34, and a controller (not shown). The rear end of the push rod 31 is fixed to the cylinder bracket 22, located to one side of the cutter 23. The front end of the push rod 31 is located on a push-off portion 311, which is used to push the sugarcane off. Preferably, the push rod 31 is L-shaped, with the push-off portion 311 being a vertical rod. The push-off portion 311 of the push rod 31 is positioned perpendicular to or intersecting the horizontally placed sugarcane. A sugarcane guide trough 32 is located directly below the sugarcane receiving trough 25, through which the cut sugarcane is directed to the next process. The guide trough 32 is an inclined plate, ensuring smoother descent of the sugarcane segments. The push rod push-off portion 311 extends horizontally, close to the inner side of the guide trough 32 near the cutter body or near the inner edge of the sugarcane receiving trough 25. When the cutter 23 cuts the sugarcane and sticks to the cutter, the cutter moves back with the sugarcane to the push-off portion 311 of the push rod 31, and the push-off portion 311 pushes the sugarcane segment off and away from the cutter, allowing the sugarcane to fall smoothly from the sugarcane trough 25, preventing it from getting stuck in the sugarcane trough 25 and affecting the subsequent cutting process.

[0027] A photoelectric sensor group 33 is installed directly above the sugarcane trough 25. The photoelectric sensor group 33 consists of two photoelectric sensors, which are mounted on the bracket 27. The photoelectric sensor group 33 is used to detect whether there are sugarcane seeds in the sugarcane trough 25 below it. When the photoelectric sensor group 33 detects that sugarcane is in the sugarcane trough 25, it transmits a signal to the controller (not shown) to start the tool movement. The magnetic induction sensor group 34 is installed on the cylinder 21. The magnetic induction sensor group 34 includes at least two magnetic induction sensors. In this embodiment, there are two magnetic induction sensors, which are respectively located in the front and rear parts of the cylinder 21. It is used to detect the synchronization and real-time status of multiple groups of cylinder piston rods controlling the knife output. The magnetic induction sensor group 34 is installed at the front and rear of the small round bar on the upper left side of the cylinder rod body to check the real-time status of the cylinder knife. When the knife command is issued, it detects whether all knives are synchronized and adjusted. The controller is data-connected to the photoelectric sensor group 33 and the magnetic induction sensor group 34 , and controls the operation of the cylinder in the seed cutting mechanism 2 according to the data information of the photoelectric sensor group 33 and the magnetic induction sensor 34 .

[0028] Preferably, one side of the sugarcane trough 25 is a cutting platform, and the other side is provided with a vertical blocking rod 26. The blocking rod 26 plays a limiting role on the sugarcane in the sugarcane trough.

[0029] Preferably, the push-off portion 311 of the push rod 31 extends to the blocking rod 26 and is arranged parallel to the blocking rod 26. When the cutter retracts, the sugarcane segments stuck to the cutter are pushed off and fall smoothly from the sugarcane trough 25 to prevent them from getting stuck in the sugarcane trough and affecting the subsequent cutting process.

[0030] Preferably, baffles (not shown) are provided on both sides of the inclined plate of the sugarcane guiding trough 32 to prevent the sugarcane segments from deflecting when falling, thus playing a good guiding role.

[0031] Preferably, in another technical solution for the sugarcane guiding trough 25 , the sugarcane guiding trough 25 is concave, the bottom plate is an inclined plate, and baffles are formed on both sides.

[0032] Preferably, a cutting table support 35 is provided directly behind the cutting table 24 and on the movable crossbar 28. The cutting table support 35 is in the shape of a right triangle, with its two short sides respectively aligned with the cutting table 24 and the movable crossbar 28. The cutting table support 35 effectively prevents the cutting table from deforming and tilting backward during prolonged cutting operations, thereby preventing problems such as incomplete cutting of the sugarcane caused by deformation and tilting of the cutting table.

[0033] Preferably, a laser distance measuring sensor 36 is further included, which is arranged between the sugarcane container 25 and the movable cross bar 28 and is used to detect the position of the cutting mechanism 2.

[0034] When cutting sugarcane, if the sugarcane is too small, some sugarcane segments may get stuck in front of the push rod 31 below the sugarcane trough 23. Therefore, a sensor 36 is added here, placed between the movable crossbar 28 and the sugarcane trough 23. The detection direction is from front to back, and it can detect the position of multiple cutting mechanisms 2. The program determines the position (between which two cutting mechanisms the sugarcane segment is stuck) and moves the cutting mechanism according to the information to prevent it from falling, saving time.

[0035] The foregoing descriptions of specific exemplary embodiments of the present invention are for purposes of illustration and description. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is apparent that many modifications and variations are possible in light of the foregoing teachings. The exemplary embodiments have been selected and described for the purpose of explaining the specific principles of the present invention and their practical application, thereby enabling those skilled in the art to realize and utilize a variety of exemplary embodiments of the present invention and various options and variations.
