Description

Technical Field

[0001] This utility model relates to sugarcane harvesting equipment, specifically a mobile sugarcane cutting and impurity removal combined operation equipment, used to cut and remove impurities from harvested whole sugarcane stalks during the sugarcane harvesting process, belonging to the field of agricultural machinery and equipment technology. Background Technology

[0002] Sugarcane is an important raw material crop for sugar production in southern my country, with a wide planting area and a huge harvest. Traditional manual sugarcane harvesting methods are labor-intensive and inefficient, and are gradually being replaced by mechanized harvesting methods. Mechanized sugarcane harvesting equipment can be divided into two categories based on its construction: combined sugarcane harvesting equipment and step-by-step sugarcane harvesting equipment. Combined sugarcane harvesting equipment refers to integrated machinery that completes a series of operations—harvesting, conveying, stripping, cutting, and removing impurities—in the sugarcane field. These machines are large and suitable for large-scale plain sugarcane growing areas. Step-by-step sugarcane harvesting equipment refers to equipment that separately completes these operations using sugarcane cutters, field collection and transport machines, sugarcane stripping equipment, sugarcane cutting equipment, and sugarcane impurity removal equipment. It is suitable for small-scale planting areas in hilly terrain and is more suitable for the current planting conditions in the main sugarcane producing areas of southern my country.

[0003] Existing sugarcane step-by-step harvesting equipment, including sugarcane cutting and cleaning equipment, is generally fixed, meaning it is installed at a designated location. This requires land for facilities, resulting in high construction costs. Furthermore, its functional integration is low, failing to achieve the integrated function of "cutting + conveying + multi-stage cleaning + mobility," making it unsuitable for field use. Utility Model Content

[0004] The purpose of this invention is to provide a mobile sugarcane cutting and cleaning combined operation equipment, which can be used as part of a step-by-step sugarcane harvesting equipment. It can be moved to the field and complete a series of operations in the field, including automatic feeding, fixed-length cutting, multi-stage cleaning and centralized output of sugarcane, which can effectively improve the mechanization and automation level of sugarcane harvesting.

[0005] The specific technical solution of this utility model is as follows: A mobile sugarcane cutting and impurity removal combined operation equipment includes a chassis, a feeding belt conveyor, a conveying and cutting assembly, a primary impurity removal fan, a discharge chain conveyor, a secondary impurity removal fan, and a power unit.

[0006] The chassis is located at the bottom of the equipment. The chassis adopts a wheeled chassis structure, including a frame and a wheel assembly that supports the frame and has a braking function. The front or rear end of the frame is provided with a lug for tractor towing.

[0007] The rear end of the feeding belt conveyor is hinged to the upper front of the frame, and the front end of the feeding belt conveyor extends forward and downward towards the frame. A front telescopic hydraulic cylinder is hinged to the front end of the frame, and the piston rod of the front telescopic hydraulic cylinder is hinged to the middle of the feeding belt conveyor. The tilt angle of the feeding belt conveyor is controlled by the front telescopic hydraulic cylinder. The feeding belt conveyor is driven by a hydraulic motor, which conveys materials from the lower front to the upper rear.

[0008] The conveying and cutting assembly is mounted on the vehicle frame at a position corresponding to the rear of the feeding belt conveyor and forms a feeding connection with the feeding belt conveyor.

[0009] The primary impurity removal fan is mounted above the vehicle frame at the rear of the corresponding conveyor cutting assembly. The primary impurity removal fan has an overhead fan support and a horizontally mounted axial flow fan supported by the fan support. The axial flow fan is driven by a hydraulic motor, which blows air downwards.

[0010] The front end of the discharge chain conveyor extends into the fan bracket of the primary impurity removal fan, directly below the axial flow fan, and is hinged to the frame. This positions the front end of the discharge chain conveyor below and behind the conveying and cutting assembly, receiving the sugarcane segments output by the assembly. The rear end of the discharge chain conveyor extends obliquely upwards and backwards towards the frame. A rear lifting cylinder is hinged to the rear end of the frame, and its piston rod is hinged to the middle of the discharge chain conveyor. The rear lifting cylinder controls the tilt angle of the discharge chain conveyor. The discharge chain conveyor is driven by a hydraulic motor, which conveys material from the lower front to the upper rear.

[0011] The secondary impurity removal fan is fixedly installed at the end of the discharge chain conveyor.

[0012] The power unit is located above the conveying and cutting assembly. The power unit is equipped with a hydraulic pump station and an electrical control system, which provide power and control to the hydraulic components of each part of the equipment.

[0013] The advantages of this mobile sugarcane cutting and cleaning combined operation equipment are as follows: This equipment can be moved to the sugarcane field by a tractor. It adopts a wheeled chassis structure, which can adapt to complex field terrain conditions. It does not require a fixed installation site, and has high flexibility and mobility.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings. In the description of the present invention, the directional terms "front," "rear," "left," and "right" are defined based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present invention, and do not refer to a specific orientation that the device or component must have, and should not be regarded as a limitation of the present invention.

[0023] like Figures 1-7 As shown, this mobile sugarcane cutting and cleaning combined operation equipment includes a chassis 1, a feeding belt conveyor 2, a conveying and cutting assembly 3, a primary cleaning fan 4, a discharge chain conveyor 5, a secondary cleaning fan 6, and a power unit 7.

[0024] The chassis 1 is located at the bottom of the equipment. The chassis 1 adopts a wheeled chassis structure, including a frame 1.1 and a wheel assembly 1.2 that supports the frame 1.1 and has a braking function. The front or rear end of the frame 1.1 is provided with a lug 1.3 for tractor towing. Furthermore, the four corners of the frame 1.1 are respectively provided with hydraulic outriggers 1.4 that can extend downwards. When the equipment is working, the hydraulic outriggers 1.4 can be lowered to the ground to provide more stable support for the equipment.

[0025] The rear end of the feeding belt conveyor 2 is hinged to the front upper part of the frame 1.1, and the front end of the feeding belt conveyor 2 extends forward and downward towards the frame 1.1. A front telescopic cylinder 8 is hinged to the front end of the frame 1.1, and the piston rod of the front telescopic cylinder 8 is hinged to the middle of the feeding belt conveyor 2. The front telescopic cylinder 8 controls the tilt angle of the feeding belt conveyor 2. The feeding belt conveyor 2 is driven by a hydraulic motor, so that the feeding belt conveyor 2 conveys materials from the front and lower to the rear and upper.

[0026] The conveying and cutting assembly 3 is mounted above the frame 1.1, corresponding to the rear of the feeding belt conveyor 2, and forms a feeding connection with the feeding belt conveyor 2. Specifically, the conveying and cutting assembly 3 has two sets of clamping conveyor rollers and one set of cutting cutter rollers; the two sets of clamping conveyor rollers are arranged one after the other, and each set of clamping conveyor rollers has an upper clamping roller 3.1 and a lower clamping roller 3.2 arranged vertically. A set of radially extending and circumferentially distributed conveying baffles 3.3 are installed on the outer side of the upper clamping roller 3.1 and the lower clamping roller 3.2. The upper clamping roller 3.1 and the lower clamping roller 3.2 are respectively driven by hydraulic motors to make the upper clamping roller 3.1 and the lower clamping roller 3.2 rotate in opposite directions. The conveying baffles 3.3 of the upper clamping roller 3.1 and the lower clamping roller 3.2 together support the sugarcane. The sugarcane is clamped and conveyed backward. The cutting roller is located at the rear end of the rear clamping and conveying roller. The cutting roller has an upper cutting roller 3.4 and a lower cutting roller 3.5 arranged vertically. A set of radially extending and circumferentially distributed wide blades 3.6 are installed on the outer side of the upper cutting roller 3.4 and the lower cutting roller 3.5. The upper cutting roller 3.4 and the lower cutting roller 3.5 are respectively driven by hydraulic motors to rotate in opposite directions. The blades 3.6 of the upper cutting roller 3.4 and the lower cutting roller 3.5 work together to cut the sugarcane into fixed length segments and push the cut sugarcane segments backward.

[0027] Furthermore, the lower clamping roller 3.2 of the clamping conveyor roller is a fixed roller, while the upper clamping roller 3.1 is a floating roller that can move up and down. Specifically, both ends of the upper clamping roller 3.1 are fixedly connected to radially extending end plates 3.7. The extended ends of the two end plates 3.7 are hinged to a fixed core rod 3.8 on the side of the upper clamping roller 3.1. The mounting holes 3.9 at both ends of the upper clamping roller 3.1 are arc-shaped elongated holes centered on the fixed core rod 3.8. The upper clamping roller 3.1 can move up and down within the limited range of the mounting holes 3.9 around the fixed core rod 3.8. When clamping and conveying sugarcane, the upper clamping roller 3.1 automatically presses down under its own weight and can adaptively move up and down according to the amount of sugarcane fed, which ensures the clamping force on the sugarcane and reduces the crushing loss of the sugarcane.

[0028] Furthermore, the blades 3.6 of the upper blade roller 3.4 and lower blade roller 3.5 of the cutting roller are fixedly mounted on the corresponding blade holders 3.10, and the height of the blades 3.6 extending from the blade holders 3.10 can be adjusted. The blades 3.6 are single-sided blades with only one inclined cutting surface. When the blades 3.6 of the upper blade roller 3.4 and lower blade roller 3.5 rotate to the cutting positions opposite each other, the inclined cutting surfaces of the blades 3.6 of the upper blade roller 3.4 and the lower blade roller 3.5 are parallel and partially overlap in the vertical position. By adjusting the extension height of the blades 3.6, the parallel gap and vertical overlap between the inclined cutting surfaces of the blades 3.6 of the upper blade roller 3.4 and the lower blade roller 3.5 can be changed, thereby ensuring the flatness of the blade edge during the cutting operation and reducing the chipping loss during sugarcane cutting.

[0029] The primary impurity removal fan 4 is mounted above the frame 1.1 at the position corresponding to the rear of the conveying and cutting assembly 3. The primary impurity removal fan 4 has an overhead fan support 4.1 and a horizontally mounted axial flow fan 4.2 supported by the fan support 4.1. The axial flow fan 4.2 is driven by a hydraulic motor, which causes the axial flow fan 4.2 to blow air downwards.

[0030] The front end of the discharge chain conveyor 5 extends into the fan bracket 4.1 of the primary impurity removal fan 4, directly below the axial flow fan 4.2, and is hinged to the frame 1.1, so that the front end of the discharge chain conveyor 5 is located below and behind the conveying and cutting assembly 3 and receives the sugarcane segments output by the conveying and cutting assembly 3. The rear end of the discharge chain conveyor 5 extends obliquely upward and backward towards the frame 1.1. A rear lifting cylinder 9 is hinged to the rear end of the frame 1.1, and the piston rod of the rear lifting cylinder 9 is hinged to the middle of the discharge chain conveyor 5. The rear lifting cylinder 9 controls the tilt angle of the discharge chain conveyor 5. The discharge chain conveyor 5 is driven by a hydraulic motor, so that the discharge chain conveyor 5 conveys materials from the front downward to the rear upward.

[0031] Furthermore, the conveyor chain of the discharge chain conveyor 5 is a conveyor chain with mesh. During the conveying process, impurities such as mud and sand can fall through the mesh to the bottom of the discharge chain conveyor 5, thereby reducing the impurity content in the sugarcane segment.

[0032] Furthermore, the portion of the front end of the discharge chain conveyor 5 that extends into the fan bracket 4.1 of the primary impurity removal fan 4 is provided with mesh baffles 5.1 on both sides to prevent the sugarcane segments from falling out from the side when receiving the output sugarcane segments of the conveying and cutting assembly 3.

[0033] The secondary impurity removal fan 6 is fixedly installed at the end of the discharge chain conveyor 5. Specifically, the secondary impurity removal fan 6 is equipped with a guide cover 6.1. The front end of the guide cover 6.1 is provided with a material inlet 6.2, which forms a feeding connection with the discharge chain conveyor 5. The rear end of the guide cover 6.1 is provided with an impurity outlet 6.3 and a sugarcane outlet 6.4, which are arranged vertically. A centrifugal fan 6.5 driven by a hydraulic motor is provided on the outside of the guide cover 6.1. Inside the guide cover 6.1, below the material inlet 6.2, there is a guide pipe 6.6. One end of the guide pipe 6.6 is closed, and the other end extends to the outside of the guide cover 6.1 and connects to the air outlet of the centrifugal fan 6.5. The guide pipe 6.6 has a row of air outlet holes 6.7 on the side wall of the pipe body inside the guide cover 6.1, which are directed towards the impurity outlet 6.3. After the sugarcane segments enter the guide hood 6.1 through the material inlet 6.2, they are blown directionally through the air outlet 6.7 of the air duct 6.6. This allows the sugarcane segments to fall from the sugarcane outlet 6.4 while the light impurities attached to the sugarcane segments are discharged from the impurity outlet 6.3.

[0034] The power unit 7 is positioned above the conveying and cutting assembly 3. The power unit 7 includes a hydraulic pump station and an electrical control system, which provide power and control to the hydraulic components of each part of the equipment. Furthermore, the hydraulic pump station is powered by a diesel engine.

[0035] like Figure 1 As shown, when using this mobile sugarcane cutting and cleaning combined operation equipment, it is first towed by a tractor to the designated sugarcane field operation area before operation. After being separated from the tractor, the power unit 7 is started to give the equipment power, the wheel assembly 1.2 of the chassis 1 is braked, and if necessary, the hydraulic outriggers 1.4 at the four corners of the frame 1.1 are extended to provide stable support for the equipment. Then, the front telescopic cylinder 8 and the rear lifting cylinder 9 are adjusted to tilt the feeding belt conveyor 2 and the discharge chain conveyor 5 to the appropriate working position, and the operation can begin.

[0036] During operation, bundles of whole sugarcane are neatly placed onto the feeding belt conveyor 2 using a sugarcane grabbing machine. The feeding belt conveyor 2 evenly feeds the whole sugarcane into the conveying and cutting assembly 3. The clamping conveyor rollers of the conveying and cutting assembly 3 clamp the whole sugarcane and convey it to the cutting cutter roller for cutting. As the cut sugarcane segments fall backward and downward into the discharge chain conveyor 5, they are blown by the primary impurity removal fan 4 to remove light impurities such as leaves and soil mixed in with the sugarcane segments. Then, the discharge chain conveyor 5 discharges the sugarcane segments. The sugarcane continues to be conveyed upwards and backwards to the secondary impurity removal fan 6. The secondary impurity removal fan 6 further blows out the remaining light impurities in the sugarcane segments through the air outlet 6.7 of the air guide duct 6.1 from the impurity outlet 6.3. Finally, the processed sugarcane segments fall downwards from the sugarcane outlet 6.4 of the guide duct 6.1 and fall into the sugarcane collection vehicle located below the secondary impurity removal fan 6 at the rear of the equipment for centralized collection. In this way, a series of operations such as automatic feeding, fixed-length cutting, multi-stage impurity removal and centralized output of sugarcane can be completed in one integrated manner.

[0037] 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.
