Description

Technical Field

[0001] This utility model relates to components of a sugarcane step-by-step harvesting equipment, specifically a low-loss conveying and cutting device for sugarcane harvesting equipment, belonging to the field of agricultural machinery and equipment technology. Background Technology

[0002] Sugarcane step-by-step harvesting equipment can complete each step of sugarcane harvesting, including cutting, spreading, collecting, transporting, peeling, segmenting, and removing impurities. The efficient mechanization of this equipment can reduce costs and increase efficiency in sugarcane production. The conveying and cutting device is a key component of this equipment, used to cut the harvested whole sugarcane stalks into segments of a certain length, which are then conveyed to the next stage for processing. Currently, existing conveying and cutting devices suffer from inadequate blade design, failing to flexibly adjust the gap and overlap between the upper and lower blades. This results in uneven blade edges, easily causing fragmentation and loss during segmentation. Furthermore, during the clamping, conveying, and cutting process, some sugarcane segments fail to move backward and fall downwards. Existing conveying and cutting devices lack a mechanism to recover these fallen segments, leading to further losses. Utility Model Content

[0003] The purpose of this invention is to provide a low-loss conveying and cutting device for sugarcane harvesting equipment, so as to reduce the problems of sugarcane segment breakage and sugarcane drop loss in existing conveying and cutting devices.

[0004] The specific technical solution of this utility model is as follows:

[0005] A low-loss conveying and cutting device for sugarcane harvesting equipment comprises five parts: a feeding belt conveyor, a clamping conveyor roller, a cutting blade roller, a return belt conveyor, and a primary chain conveyor.

[0006] The feeding belt conveyor is located at the front end and is driven by a feeding motor.

[0007] The clamping conveyor roller is located behind the feeding belt conveyor and forms a feeding connection with the feeding belt conveyor; the clamping conveyor roller has two sets arranged at intervals, each set of clamping conveyor rollers has an upper clamping roller and a lower clamping roller installed vertically, the upper clamping roller and the lower clamping roller are respectively driven by a hydraulic motor, the upper clamping roller rotates counterclockwise and the lower clamping roller rotates clockwise when viewed from left to right, the lower clamping roller is a fixed roller, the upper clamping roller is a floating roller that can float up and down, and a set of radially extended and circumferentially distributed conveying baffles are installed on the outside of the upper clamping roller and the lower clamping roller.

[0008] The cutting roller is located behind the clamping conveyor roller and forms a feeding connection with the clamping conveyor roller. The cutting roller has an upper cutting roller and a lower cutting roller installed vertically. Both the upper and lower cutting rollers are fixed rollers and are driven by hydraulic motors. Viewed from left to right, the upper cutting roller rotates counterclockwise and the lower cutting roller rotates clockwise. The upper and lower cutting rollers have a set of radially extending and circumferentially distributed wide blades installed on the outer side of their roller bodies. The blades are fixedly installed on the corresponding blade holders and the height of the blades extending from the blade holders can be adjusted. The blades are single-edged blades with only one inclined cutting edge. When the blades of the upper and lower cutting rollers rotate to the cutting positions of the upper and lower cutting rollers, the inclined cutting edges of the blades of the upper and lower cutting rollers are parallel and opposite to each other and partially overlap in the vertical position. By adjusting the extension height of the blades, the parallel gap and vertical overlap between the inclined cutting edges of the blades of the upper and lower cutting rollers can be changed.

[0009] The return material belt conveyor is located directly below the clamping conveyor roller and the cutting roller, and the return material belt conveyor is driven by a return material motor.

[0010] The primary chain conveyor is located behind and below the cutting roller and connects with the return material belt conveyor for feeding. The primary chain conveyor is equipped with a feeding motor for driving.

[0011] The advantages of this invention are as follows: By adjusting the extension height of the blades, the cutting rollers of this conveying and cutting device can adjust the parallel gap and overlap between the inclined blade surfaces of the upper and lower rollers to a suitable level, thereby ensuring the flatness of the blade edge during cutting and reducing the loss of sugarcane during cutting. Furthermore, by installing a return belt conveyor below the clamping conveyor rollers and the cutting rollers, and connecting the return belt conveyor to the primary chain conveyor at the rear, the return belt conveyor can collect and transport sugarcane that falls from the clamping and cutting station back to the primary chain conveyor, thus returning the lost sugarcane to the main conveyor line and reducing the loss from falling sugarcane.

Detailed Implementation

[0017] 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.

[0018] like Figures 1-4 As shown, this conveying and cutting device consists of five parts: a feeding belt conveyor 1, a clamping conveyor roller 2, a cutting blade roller 3, a return belt conveyor 4, and a primary chain plate conveyor 5.

[0019] The feeding belt conveyor 1 is located at the front end and is driven by a feeding motor.

[0020] The clamping conveyor roller 2 is located behind the feeding belt conveyor 1 and forms a feeding connection with the feeding belt conveyor 1. The clamping conveyor roller 2 has two sets arranged at intervals. Each set of clamping conveyor roller 2 has an upper clamping roller 2.1 and a lower clamping roller 2.2 installed vertically. The upper clamping roller 2.1 and the lower clamping roller 2.2 are respectively driven by hydraulic motors. When viewed from left to right, the upper clamping roller 2.1 rotates counterclockwise and the lower clamping roller 2.2 rotates clockwise. The lower clamping roller 2.2 is a fixed roller, and the upper clamping roller 2.1 is a floating roller that can float up and down. A set of radially extended and circumferentially distributed conveying baffles 2.3 are installed on the outer side of the upper clamping roller 2.1 and the lower clamping roller 2.2.

[0021] The cutting roller 3 is located behind the clamping conveyor roller 2 and forms a feeding connection with the clamping conveyor roller 2. The cutting roller 3 is provided with an upper cutting roller 3.1 and a lower cutting roller 3.2 installed vertically. Both the upper cutting roller 3.1 and the lower cutting roller 3.2 are fixed rollers. The upper cutting roller 3.1 and the lower cutting roller 3.2 are respectively driven by hydraulic motors. When viewed from left to right, the upper cutting roller 3.1 rotates counterclockwise and the lower cutting roller 3.2 rotates clockwise. A set of radially extending and circumferentially distributed wide blades 3.3 are installed on the outer side of the upper cutting roller 3.1 and the lower cutting roller 3.2. The blades 3.3 are fixedly installed on the corresponding blade holders 3. 4. The height of the blade 3.3 extending from the tool holder 3.4 is adjustable. The blade 3.3 has a single-sided blade with only one inclined cutting edge. When the blades 3.3 of the upper and lower cutting rollers 3.1 and 3.2 rotate to the cutting positions opposite each other, the inclined cutting edges of the blades 3.3 of the upper cutting roller 3.1 and the inclined cutting edges of the blades 3.3 of the lower cutting roller 3.2 are parallel and partially overlap in the vertical position. By adjusting the extension height of the blade 3.3, the parallel gap and vertical overlap between the inclined cutting edges of the blades 3.3 of the upper cutting roller 3.1 and the inclined cutting edges of the blades 3.3 of the lower cutting roller 3.2 can be changed.

[0022] The return material belt conveyor 4 is located directly below the clamping conveyor roller 2 and the cutting blade roller 3, and the return material belt conveyor 4 is equipped with a return material motor for driving.

[0023] The primary chain conveyor 5 is located behind and below the cutting roller 3 and forms a feeding connection with the return belt conveyor 4. The primary chain conveyor 5 is equipped with a feeding motor for driving.

[0024] Furthermore, the feeding motor is a controllable forward and reverse motor. When the clamping conveyor roller 2 is blocked, the feeding motor can be reversed to achieve the material return function, so as to ensure the smooth flow of the sugarcane conveying channel.

[0025] Furthermore, the feeding belt conveyor 1 and the primary chain plate conveyor 5 are independent devices, and the clamping conveyor roller 2, the cutting blade roller 3 and the return belt conveyor 4 are all installed on the same frame.

[0026] Furthermore, the upper clamping roller 2.1 has radially extending end plates 2.4 fixedly connected to both ends of its roller body. The extended ends of the two end plates 2.4 are hinged to the fixed core rod 2.5 on the side of the upper clamping roller 2.1. The mounting holes 2.6 at both ends of the upper clamping roller 2.1 are arc-shaped elongated holes centered on the fixed core rod 2.5. The upper clamping roller 2.1 can float up and down within the limited range of the mounting holes 2.6 around the fixed core rod 2.5. When clamping and conveying sugarcane, the upper clamping roller 2.1 automatically presses down under its own weight and can adaptively float up and down according to the amount of material coming in, which ensures the clamping force on the sugarcane and reduces the crushing loss of the sugarcane.

[0027] Furthermore, the conveyor chain of the primary 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 primary chain conveyor 5, thereby reducing the impurity content in the sugarcane segment.

[0028] Furthermore, the conveying plate 2.3 of the clamping conveying roller 2 is made of a rubber plate with a wavy toothed outer edge to enhance the conveying friction and prevent the sugarcane from being pinched.

[0029] Furthermore, fixed arc-shaped protective covers 3.5 are respectively provided above the upper cutter roller 3.1 and below the lower cutter roller 3.2 of the cutting roller 3 to enhance the operational safety of the equipment.

[0030] like Figure 1 As shown, when this conveying and cutting device is working, whole sugarcane stalks are conveyed to the clamping conveyor roller 2 via the feeding belt conveyor 1. The clamping conveyor roller 2 floats and clamps the sugarcane according to the incoming material. After the clamping conveyor roller 2 feeds the whole sugarcane into the cutting roller 3, the cutting roller 3 cuts the whole sugarcane into sugarcane segments of a certain length. The cut sugarcane segments are thrown onto the primary chain conveyor 5, which then conveys the cut sugarcane segments to the next processing stage. During the clamping and conveying process of the clamping conveyor roller 2 and the cutting process of the cutting roller 3, a small portion of sugarcane will fall onto the return belt conveyor 4 directly below. The return belt conveyor 4 collects the fallen sugarcane and conveys it back onto the primary chain conveyor 5 for further conveying.

[0031] 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.
