Description

Technical Field

[0001] This utility model relates to a sugarcane harvesting device, specifically a sugarcane harvester that can quickly change different types of sugarcane buckets, belonging to the field of agricultural machinery and equipment technology. Background Technology

[0002] A sugarcane harvester is a device used to harvest sugarcane in sugarcane fields. Its operation involves cutting the sugarcane from the root and transporting the harvested sugarcane to a sugarcane collection bucket at the rear of the machine for automatic stacking. When the collection bucket is full, the sugarcane is transported to a designated unloading point in the field for centralized unloading. This allows transport vehicles to transport the harvested sugarcane in batches at a fixed location, thereby improving transport efficiency.

[0003] Because the unloading points in each sugarcane field vary—some are suitable for unloading from the left side of the sugarcane harvester, others from the right, and still others from the rear—existing sugarcane harvesters have several types of sugarcane collecting buckets, including side-tipping buckets, rear-tipping buckets, and buckets that don't require tipping. However, most sugarcane harvesters on the market are equipped with a fixed type of collecting bucket. Quickly changing to different types of collecting buckets for different unloading points is difficult because the different types of collecting buckets have different installation connection points and dimensions with the machine body, making them incompatible. Even if they are barely compatible, the disassembly and replacement of the collecting buckets is extremely cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a sugarcane harvester that can quickly change different types of sugarcane buckets, so that the sugarcane harvester can adapt to the unloading requirements of different unloading points by quickly changing different types of sugarcane buckets.

[0005] The specific technical solution of this utility model is as follows: A sugarcane harvester with interchangeable sugarcane buckets of different types features a tracked chassis with a body mounted on top. The body houses the power system and a driver's cab positioned slightly to the left. The machine is equipped with at least two different types of sugarcane buckets, one fixedly mounted on a standard mounting bracket at the rear of the machine, with the remainder as spares. At the upper front of the machine body is a top-cutting device for trimming the tops of the sugarcane to be harvested. At the lower front of the machine body are a sugarcane straightener for righting lodged sugarcane, a cutting device for root cutting, and a primary clamping and conveying device for feeding the sugarcane into the cutting device and conveying it backwards. Above the machine body, on the right side of the driver's cab, is a secondary clamping and conveying device for receiving the sugarcane output from the primary clamping and conveying device and conveying it backwards to the sugarcane bucket.

[0006] The standard mounting frame is located at the lower rear of the machine and includes a central support and two side frames on the left and right sides of the central support. The central support has two rearward-extending main support beams on its upper part, each with two lower limiting plates flush with the top surface of the main support beam and equipped with connection holes. The two side frames are rearward-extending, oppositely positioned inverted L-shaped side limiting angle plates, with connection holes on their side walls. Each sugarcane hopper has a standard base frame supporting the hopper body. The standard base frame has horizontal support rods on both sides, and two longitudinal support rods are fixedly connected between the two horizontal support rods at the front position. The end is welded with an upper perforated plate flush with the bottom surface of the longitudinal frame rod. The left and right crossbeams of the standard base frame are respectively welded with side edges, and the front end of the side edge is provided with a plug with a connection hole. When the sugarcane collecting bucket is installed on the standard mounting frame, the two longitudinal frame rods of the standard base frame are supported on the main support beam of the middle bracket of the standard mounting frame. The upper perforated plate is aligned with the lower limit plate of the main support beam and is locked with bolts passing through the connection hole. The side plug of the standard base frame is inserted into the inner side wall of the side frame of the standard mounting frame and is locked with bolts passing through the connection hole. Different types of sugarcane collecting buckets can be quickly disassembled and replaced through the standardized connection between their standard base frame and the standard mounting frame on the machine body.

[0007] Furthermore, the sugarcane collecting bucket is equipped with two types: a side-tipping unloading sugarcane collecting bucket that can tip over to the left or right and a bottom-unloading sugarcane collecting bucket that can be lifted and moved down to unload.

[0008] This sugarcane harvester features a standard mounting frame at the rear of the machine and is equipped with at least two different types of sugarcane collection buckets. One bucket is mounted on the standard mounting frame at the rear of the machine, while the others are spare replacement parts. Each collection bucket has a standard base frame with simple connecting components corresponding to the standard mounting frame. Different types of collection buckets can be quickly disassembled and replaced through the standardized connection between their standard base frames and the standard mounting frames on the machine. Therefore, this machine can adapt to the unloading requirements of different unloading points by quickly changing different types of collection buckets, and the operation of changing collection buckets is very simple and convenient. Furthermore, the machine's overall structure is compact and rationally laid out, enabling efficient implementation of sugarcane harvesting processes such as cane felling, cutting, conveying, collection, and unloading. Operation is simple and work efficiency is high. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings. In the description of the present invention, directional terms such as "front," "rear," "left," "right," "up," and "down" are based on the accompanying drawings. Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 8 , Figure 10 The indicated orientation is defined from the perspective of the sugarcane harvester operator.

[0023] like Figures 1-12 As shown, this sugarcane harvester is equipped with a tracked chassis 1 that can move, and a body 2 is located above the tracked chassis 1. The body 2 is equipped with a power system and a cab 3 located slightly to the left. The machine is equipped with at least two different types of sugarcane collection buckets 4, one of which is fixedly installed on a standard mounting frame 5 at the rear of the body 2, and the rest are spare replacement parts. At the upper front of the body 2, there is a top-cutting device 6 for cutting the tops of the sugarcane to be harvested. At the lower front of the body 2, there is a sugarcane straightener 7 for straightening lodged sugarcane, a cutting device 8 for cutting the roots of the sugarcane, and a primary clamping and conveying device 9 for feeding the sugarcane into the cutting device 8 and conveying it backward. Above the body 2, on the right side of the cab 3, there is a secondary clamping and conveying device 10 for receiving the sugarcane output from the primary clamping and conveying device 9 and conveying it backward to the sugarcane collection bucket 4.

[0024] The standard mounting frame 5 is located at the lower rear of the machine body 2, and includes a central support 5.1 and two side frames 5.2 located on the left and right sides of the central support 5.1. The central support 5.1 has two rearwardly extending main support beams 5.1a mounted on its upper part. Each main support beam 5.1a has two lower limiting plates 5.1b, flush with the top surface of the main support beam 5.1a and equipped with connecting holes. The two side frames 5.2 are rearwardly extending, oppositely arranged in an inverted L-shaped side limiting angle plate, with connecting holes on their side walls. Each sugarcane hopper 4 has a standard base frame 4.1 at its lower part to support the hopper body 4.1 has horizontal support rods 4.1a on both sides of the standard base frame 4.1. Two longitudinal support rods 4.1b are fixedly connected between the two horizontal support rods 4.1a at the front position. The front ends of the longitudinal support rods 4.1b are welded... The standard base frame 4.1 has an upper perforated plate 4.1c that is flush with the bottom surface of the longitudinal frame rod 4.1b. The left and right horizontal frame rods 4.1a of the standard base frame 4.1 are welded with side edges, and the front end of the side edge is provided with a plug 4.1d with a connection hole. When the sugarcane hopper 4 is installed on the standard mounting frame 5, the two longitudinal frame rods 4.1b of the standard base frame 4.1 are supported on the main support beam 5.1a of the middle support 5.1 of the standard mounting frame 5. The upper perforated plate 4.1c is aligned with the lower limit plate 5.1b of the main support beam 5.1a and is locked with bolts passing through the connection hole. The side plug 4.1d of the standard base frame 4.1 is inserted into the inner side wall of the side frame 5.2 of the standard mounting frame 5 and is locked with bolts passing through the connection hole. Different types of sugarcane hoppers 4 can be quickly disassembled and replaced through the standardized connection between their standard base frame 4.1 and the standard mounting frame 5 on the machine body 2.

[0025] Furthermore, the sugarcane collecting bucket 4 is equipped with two types: a side-tipping unloading sugarcane collecting bucket that can tip over to the left or right and a bottom-unloading sugarcane collecting bucket that can be lifted and moved down to unload without tipping.

[0026] The side-tipping unloading sugarcane hopper is equipped with a standard base frame 4.1. Inside the standard base frame 4.1, there is a middle frame 4.3 that can be stored inside the standard base frame 4.1 and is flush with the standard base frame 4.1. The right end of the middle frame 4.3 is hinged to the right end of the standard base frame 4.1 and is equipped with a first linkage mechanism 4.5 driven by a first tilting cylinder 4.4 to control the tilting or storage of the middle frame 4.3. The middle frame 4.3 is equipped with two longitudinal beams 4.6 that can be stored on the top surface of the middle frame 4.3. The inverted trapezoidal bucket body 4.2 is fixedly installed on the two longitudinal beams 4.6. The left ends of the two longitudinal beams 4.6 are hinged to the left end of the middle frame 4.3 and are equipped with a second linkage mechanism 4.8 driven by a second tilting cylinder 4.7 to control the tilting or storage of the longitudinal beams 4.6. When the first tilting cylinder 4.4 drives the middle frame 4.3 to tilt up and the second tilting cylinder 4.7 controls the longitudinal beam 4.6 to retract, the bucket body 4.2 can be tilted and unloaded on the right side; when the first tilting cylinder 4.4 controls the middle frame 4.3 to retract and the second tilting cylinder 4.7 drives the longitudinal beam 4.6 to tilt up, the bucket body 4.3 can be tilted and unloaded on the left side.

[0027] The non-tipping unloading sugarcane hopper is equipped with a standard base frame 4.1. The standard base frame 4.1 supports the hopper body 4.2 via planar four-bar linkages 4.9 on both sides. Lifting cylinders 4.10 on both sides of the standard base frame 4.1 drive the planar four-bar linkages 4.9 to rotate, thereby lifting the hopper body 4.2 to move backward or lowering it forward. The hopper body 4.2 has vertical frames on both sides. The lower edges of the two vertical frames are hinged to a pair of rotatable, openable bottom gates. Clamping cylinders 4.11 on the outer sides of the two vertical frames drive the opening and closing of the two bottom gates. When the two bottom gates are closed, a V-shaped support is formed at the lower end of the two vertical frames. After the lifting cylinders 4.10 drive the hopper body 4.2 to move backward, the clamping cylinders 4.11 control the opening of the two bottom gates, enabling non-tipping unloading of the hopper body 4.2.

[0028] A front frame 11 is located at the lower front end of the machine body 2. The upper rear end of the front frame 11 is hinged to corresponding hinge seats at the front end of the machine body 2 on both the left and right sides. A frame lifting cylinder 12 is hinged between the front frame 11 and the machine body 2, and the swing angle of the front frame 11 is controlled by the frame lifting cylinder 12. Two spiral roller-type sugarcane lifters 7 are mounted at the front end of the front frame 11, arranged in a figure-eight shape with the front lower than the rear. A primary clamping and conveying device 9 is mounted on the front frame 11 at the rear inner side of the two sugarcane lifters 7. Below the primary clamping and conveying device 9, the front frame 11 is... A cutting device 8 is installed, consisting of two cutting discs 8.1, each driven by a hydraulic motor. The two cutting discs 8.1 are staggered vertically, and their disc supports 8.2 are connected as a single unit via a disc connecting rod 8.3 to ensure rigidity and prevent interference that could cause blade breakage. The disc connecting rod 8.3 is hinged to the front frame 11, and a disc lifting cylinder 8.4 is hinged between the disc supports 8.2 and the front frame 11, controlling the cutting height of the cutting discs 8.1. The cutting height of the cutting discs 8.1 can be adjusted according to different ridge heights to ensure that the sugarcane is cut into the soil, which is beneficial for the growth of the sugarcane rhizomes the following year. Furthermore, a weed-blocking ring 8.1a is provided around the top of the cutting disc 8.1 corresponding to the blade shaft to prevent the blade shaft above the cutting disc 8.1 from being entangled by weeds and causing rotational blockage.

[0029] Both the primary clamping conveyor 9 and the secondary clamping conveyor 10 are equipped with two inclined conveyor chains, one lower at the front and one higher at the rear, positioned on the same inclined plane. Each conveyor chain is driven by a hydraulic motor to rotate in opposite directions at the same speed. Densely distributed, soft, wide rubber shims are fixedly connected to the periphery of the conveyor chains, moving synchronously with them. The rubber shims on adjacent chain segments of the two conveyor chains are distributed opposite each other and partially overlap, thus forming a clamping conveying channel. The clamping conveying channel of the primary clamping conveyor 9 has a V-shaped entrance and extends from the front center to the right rear to the front of the machine body 2. The clamping conveying channel of the secondary clamping conveyor 10... The clamping and conveying channel outlet of the primary clamping and conveying device 9 extends from the front of the machine body 2 to the top of the sugarcane collection hopper 4 on the right side of the machine body 2. The secondary clamping and conveying device 10 has upper guide bars 10.1 on the left and right sides of the upper end of its clamping and conveying channel to limit and guide the sugarcane conveying. The machine body 2 has a slanted support groove 10.3 below the clamping and conveying channel of the corresponding secondary clamping and conveying device 10, which is inclined in the same direction as the secondary clamping and conveying device 10. The secondary clamping and conveying device 10 has lower guide bars 10.2 extending to the left at the lower end of the outlet of its clamping and conveying channel to guide the sugarcane to fall into the middle of the sugarcane collection hopper 4. The clamping and conveying channel uses soft, wide rubber blades to flexibly clamp and convey the sugarcane, making it less likely to damage the sugarcane or its skin during the conveying process. Furthermore, the rubber blades are hollow V-shaped petals so that the two sets of opposing and partially overlapping rubber blades in the clamping and conveying channel can form a better flexible clamping and conveying effect.

[0030] The trimming device 6 is equipped with a fixed seat 6.1 installed on the lower front of the cab 3 on the left side of the fuselage 2. The fixed seat 6.1 is hinged to an upper connecting rod 6.2 and a lower connecting rod 6.3 that extend forward and upward and are parallel vertically. The front ends of the upper connecting rod 6.2 and the lower connecting rod 6.3 are bent to the right to the position corresponding to the middle of the fuselage and then bent forward. Then, a mounting seat 6.4 with a trimmer 6.6 is hinged at the front end. A trimming lifting cylinder 6.5 is hinged between the fuselage 2 and the lower connecting rod 6.3. The trimming lifting cylinder 6.5 drives the lower connecting rod 6.3 and the upper connecting rod 6.2 to simultaneously lift the mounting seat 6.4 with the trimmer 6.6 and control the lifting height. The middle and rear sections of the upper connecting rod 6.2 and the lower connecting rod 6.3 are offset to the left front side of the machine body 2. This prevents the upper connecting rod 6.2 and the lower connecting rod 6.3 from colliding with the sugarcane when the sugarcane is fed into the cutting device 8 by the primary clamping and conveying device 9 after the sugarcane has been cut by the top cutter 6.6. Furthermore, the top cutter 6.6 is equipped with a horizontally positioned top cutter disc driven by a hydraulic motor. Below the top cutter disc are forward-extending outward V-shaped gathering forks 6.7 to gather the sugarcane tails before cutting.

[0031] Before operating this sugarcane harvester, the appropriate type of sugarcane collection hopper 4 should be replaced according to the unloading requirements of the unloading point. When operating this sugarcane harvester, first align the sugarcane rows, adjust the swing angle of the front frame 11 through the frame lifting cylinder 12, control the cutting height of the cutting disc 8.1 through the cutter disc lifting cylinder 8.4, and control the cutting height of the tip cutter 6.6 through the tip lifting cylinder 6.5. Proceed forward at the operating speed. First, the two sugarcane straighteners 7 straighten the sugarcane that has fallen to the left and right sides. The tip cutter 6.6 cuts the tips of the sugarcane to be harvested. Then, the cutting disc 8.1 of the cutting device 8 cuts the sugarcane to the soil. Then, the primary clamping and conveying device 9 clamps the cut sugarcane and conveys it backward to the secondary clamping and conveying device 10. The secondary clamping and conveying device 10 then continues to convey the sugarcane backward, so that the output sugarcane falls neatly and orderly into the sugarcane collection hopper 4. After the harvested sugarcane is full, the machine is driven to the designated unloading point for centralized unloading. After unloading, it is driven back to continue the sugarcane harvesting operation.

[0032] The above illustrations are merely typical embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
