Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, specifically a self-propelled harvester. Background Technology

[0002] A reaper is a specialized agricultural harvesting machine primarily used to cut crops and spread them out in strips for drying. These strips are then picked up and threshed by a combine harvester. After cutting crops such as wheat stalks, the reaper spreads them on the stubble, creating overlapping ears of grain for drying. The dried grain strips are then picked up by a combine harvester equipped with a pickup mechanism. It can also be used for harvesting pasture. Reapers first appeared in the late 1920s and were subsequently widely used in countries such as the United States, Canada, and the Soviet Union. In China, their use was gradually promoted in state-owned farms in Northeast China starting in 1947, and research and production began in 1952.

[0003] Common self-propelled harvesters typically use gasoline or diesel engines as their power source. They drive the header and walking system through hydraulic or mechanical transmission for harvesting. The crop is separated by the divider at the front of the header, and the stalk lifter lifts the fallen stalks to ensure a clean cut. Then, the chain drives the alloy blades distributed on the surface to rotate at high speed to cut the crop roots. The cut crop is then transported upright and laterally to the right-side discharge port by the combined action of the reel, conveyor belt, and load spring, and laid out in strips in the field.

[0004] During the use of the aforementioned self-propelled harvester, it is necessary to use the divider at the front of the cutter to separate the crops and the rotating crop lifter to straighten the crops. However, during the separation process, the surface of the divider shell will be in contact with the crops and the field for a long time, resulting in frequent contact with mud and water and collisions with the crops. This causes the surface of the divider to rust and wear, so it needs to be replaced. The traditional installation method uses multiple sets of bolts for fixing, which makes the replacement process of the divider part quite cumbersome and affects the normal operation efficiency during the busy farming season.

[0009] Furthermore, the end of the divider is threadedly fixed to the dividing head, and the divider slides with the track frame via the guide rail frame.

[0010] Furthermore, the guide rail frame is elastically fastened to both sides of the track frame by buckles on both sides of the inner wall of the slide groove, and the buckle ends are triangular.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] In this embodiment, the present invention provides a self-propelled harvesting and drying machine, such as... Figures 1-5 As shown, the system includes a main body 1, a cutting and drying rack 2 fixed to the front end of the main body 1, a frame 101, an engine 102 fixed to the top center of the frame 101, a main transmission frame 103 connected to one side of the engine 102, a transmission box 104 connected to the bottom end of the main transmission frame 103, a secondary transmission frame 105 fixed to one side of the transmission box 104, an axle 106 connected to one end of the secondary transmission frame 105, and a transmission chain 202 driven by a sprocket on one side of the transmission box 104.

[0024] To ensure the stability and convenience of this self-propelled stalker during operation, such as Figure 1 As shown, this self-propelled harvester integrates the transmission box 104, transmission frame, and harvester frame 2 via the frame 101, forming an integrated design that is convenient for users to operate by holding the handle. Tires are fixed at both ends of the axle 106, and the engine 102 provides driving force for the overall movement of the equipment and the transmission chain 202 and the harvester wheel, enabling the harvester to move with the operator and stably carry out the harvesting and drying process of crops in the field, providing convenience.

[0025] like Figure 2-5 As shown, the harvesting rack 2 includes a guard plate frame 201, and a transmission chain 202 is distributed vertically inside the guard plate frame 201. Alloy blades 203 are distributed on the outer wall of the transmission chain 202. A bottom support frame 204 is fixed at the bottom end of the guard plate frame 201, and a docking frame 205 is fixed at the top of the bottom support frame 204. A track frame 206 is fixed at the center of the top surface of the docking frame 205, and pulleys 207 are distributed on both sides of the top surface of the docking frame 205. A divider 208 is attached to the top surface of the pulleys 207, and a divider head 209 is engaged at the front end of the divider 208. A guide rail frame 210 is fixed at the center of the bottom surface of the divider 208. A groove 211 is opened at the center of the bottom surface of the guide rail frame 210, and a spring frame 212 is fixed at one end of the inner wall of the groove 211. Buckles 213 are distributed on both sides of the inner wall of the groove 211, and springs 214 are connected to the inner walls of the buckles 213.

[0026] To facilitate quick replacement of the divider 208 and ensure efficient use, such as Figure 2-5 As shown, this self-propelled harvester can divert crops through multiple sets of docking frames 205 fixed to the front end of the guard plate frame 201 and the divider 208, making harvesting easier. The divider 208 can be quickly docked with the guide rail frame 210 and the slide 211 and the track frame 206, and can be kept in place by the elastic telescopic buckle 213. The rear end of the track frame 206 is also attached to the spring frame 212 at one end of the slide 211. In use, this can reduce the force generated by the collision of the end of the divider 208 and provide cushioning. When disassembling, the divider 208 can be pulled out from the docking frame 205 along the slide 211. The disassembly and installation process is convenient, without the need for multiple sets of fasteners, making it easy to replace and use, and improving efficiency.

[0027] In summary, when using this self-propelled harvester, the user first slides each set of harvesters 208 to the rail frame 206 via the groove 211 at the center of the bottom surface of the guide rail frame 210 until they are in place. Then, the latches 213 on both sides of the inner wall of the groove 211 engage with the outer walls of the rail frame 206, completing the installation. Simultaneously, the rear end of the rail frame 206 engages with the spring frame 212 at one end of the groove 211. The user can then operate the frame 101 by holding the handle. Driven by the engine 102 of the frame 101, the main transmission frame 103 provides power to the transmission box 104. The drive box 104, together with the auxiliary drive frame 105, provides transmission power to the axle 106 and the transmission chain 202 and the lifting reel of the harvester frame 2. This type of transmission method, which uses a universal joint drive shaft and a drive sprocket, is commonly used in the prior art, especially in self-propelled harvesters. Therefore, it will not be elaborated on in this solution. When the transmission chain 202 and the lifting reel are driven at high speed, as the user operates the device, the crops are sequentially diverted and straightened and placed onto the surface of the transmission chain 202. The alloy blades 203, which rotate through the surface of the transmission chain 202, harvest the crops, completing the operation.
