Description

Technical Field

[0001] This utility model relates to the field of feeding technology for semi-feeding harvesters, specifically to the feeding device for semi-feeding harvesters. Background Technology

[0002] As is well known, the development of harvesters varies greatly across different regions of my country. In plains areas such as northern my country, harvesters were used earlier and have now completely replaced the heavy manual labor of farmers. However, due to the special terrain, agricultural mechanization has not yet been fully realized in mountainous and hilly areas of my country.

[0003] Currently, the feeding devices of commonly available semi-feeding harvesters generally suffer from the problem of not being able to flexibly adjust the harvesting range. The structural design of many feeding devices is relatively fixed, making it difficult to adjust key parameters such as the width or angle of the feeding device according to the actual situation when harvesting crops with different planting densities and row spacings. For example, when facing sparsely planted rice fields, existing feeding devices cannot effectively expand their working range, resulting in some rice not being fed in a timely and smooth manner, thus causing harvesting omissions and reducing the integrity and efficiency of the harvest. Summary of the Invention

[0004] Technical problems to be solved

[0005] In order to overcome the problem that the feeding device of the existing semi-feeding harvester cannot adjust the feeding angle, this utility model provides a feeding device for a semi-feeding harvester with an adjustable feeding angle.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] See Figures 1 to 5 The feeding device of a semi-feeding harvester includes a conveying frame 1, a conveying assembly 2, a conveying pipe 3, a cutting assembly 4, a collecting assembly 5, and an adjusting assembly 6.

[0031] The conveying frame 1 is the main frame of the entire feeding device. It is made of sturdy metal materials, such as carbon steel or stainless steel. The internal space is used to accommodate the conveying assembly 2, while the external structure provides the mounting base for other components. The conveying assembly 2 is installed inside the conveying frame 1 and is used to convey crops. The conveying pipe 3 is fixedly installed on the side of the conveying frame 1 and is made of metal or plastic tubing. It is connected to the conveying frame 1. The function of the conveying pipe 3 is to further convey the crops in the conveying frame 1 to the subsequent processing parts. The cutting assembly 4 is installed on the conveying frame 1 and is used to cut crops. The collecting assembly 5 is installed on the top of the conveying frame 1 and is used to collect the cut crops.

[0032] The fixing plate 7 of the adjusting component 6 is fixedly installed on the side of the conveying frame 1. It is made of metal sheet and is firmly connected to the conveying frame 1 by welding or bolting. The first fixing block 8, made of metal, is fixedly installed on the fixing plate 7 by welding or bolting. A rotating shaft 34 is rotatably installed between the first fixing blocks 8. The rotating shaft 34 is made of metal and is installed on the first fixing blocks 8 at both ends by rotating components such as bearings to ensure the flexibility of rotation. The second fixing block 35 is rotatably installed on the rotating shaft 34 and is staggered with the first fixing block 8. An adjusting frame 9 is fixedly installed on the side of the second fixing block 35. The adjusting frame 9 is made of metal or engineering plastic. By rotating the rotating shaft 34, the second fixing block 35 and the adjusting frame 9 can be rotated, thereby adjusting the position and angle of the adjusting frame 9, so as to adjust the conveying angle of the conveying component 2 to adapt to different crops and harvesting conditions.

[0033] First, refer to Figure 5In this embodiment, the connecting block 10 fixedly installed on the side of the adjusting frame 9 is made of metal and is firmly connected to the adjusting frame 9 by welding or bolting. A first rotating rod 11 is rotatably installed on the connecting block 10, and a second rotating rod 12 is rotatably installed between the first rotating rods 11. These rotating rods are made of metal and are connected to each other by rotating components such as bearings to ensure the flexibility of rotation. A first motor 14 is installed on the mounting plate 13 fixedly installed on the side of the conveying frame 1. A third rotating rod 15 is connected to the output shaft of the first motor 14 by a key. A fourth rotating rod 16 is rotatably mounted on the upper part of the conveyor, and the fourth rotating rod 16 is rotatably mounted with the second rotating rod 12. When the first motor 14 is started, the output shaft drives the third rotating rod 15 to rotate. The third rotating rod 15 is rotatably connected with the fourth rotating rod 16, which in turn drives the fourth rotating rod 16 to rotate. Furthermore, through the connection between the fourth rotating rod 16 and the second rotating rod 12, the second rotating rod 12 is rotated, which ultimately drives the adjusting frame 9 to rotate, thereby adjusting the conveying angle of the conveying component 2. This transmission structure can precisely control the rotation angle and position of the adjusting frame 9 to adapt to different harvesting needs.

[0034] Then, refer to Figure 2 In this embodiment, the conveying auger 17 of the conveying assembly 2 is rotatably mounted inside the conveying frame 1. The conveying auger 17 consists of spiral blades and a shaft, and is manufactured by welding or casting. A second motor 19 is mounted on the side of the conveying frame 1, and a first pulley 20 is fixedly mounted on its output shaft. Second pulleys 21 are fixedly mounted on both sides of the conveying auger 17. Through the transmission between the first pulley 20 and the second pulley 21, the second motor 19 drives the conveying auger 17 to rotate, conveying the crops inside the conveying frame 1. The conveyor belt 18 installed inside the conveying pipe 3 is used to further convey the crops inside the conveying frame 1 to the rear... In the continuation section, a third pulley 22 is fixedly installed on the side of the conveyor belt 18. A first belt 23 is driven between the second pulley 21 and the third pulley 22 on one side. A drive rod 24 is rotatably installed on the first pulley 20. The drive rod 24 is rotatably installed with the second pulley 21 on the other side. Through this transmission structure, the power of the second motor 19 not only drives the conveyor auger 17, but also drives the conveyor belt 18 to rotate through the first pulley 20, the first belt 23, the third pulley 22 and the drive rod 24, so as to realize the conveying of crops in the conveying pipe 3 and ensure that the crops can pass smoothly through the entire conveying system.

[0035] Secondly, see Figure 3 and Figure 4In this embodiment, the cutting assembly 4 includes at least two cutting blades 25, which are slidably disposed on the side of the conveying frame 1 in a staggered manner. A movable frame 26 is fixedly disposed on the side of the top cutting blade 25. The movable frame 26 is made of metal and is connected to the cutting blade 25 by welding or bolting. A vertical column 27 is fixedly disposed inside the movable frame 26 for cooperating with other components to realize the movement of the cutting blade 25. A rotating column 28 is rotatably disposed on the side of the conveying frame 1. At least two movable plates 29 are fixedly disposed on the rotating column 28, one of which is in contact with the vertical column 27, and the other... A movable plate 29 is attached to a drive rod 24. When the drive rod 24 rotates, it drives the movable plate 29 attached to it to rotate, which in turn drives another movable plate 29 to rotate through the rotating column 28. This causes the movable plate 29 attached to the vertical column 27 to push the vertical column 27 to move, thereby causing the top cutting blade 25 to slide on the side of the conveying frame 1. At the same time, since the cutting blades 25 are staggered vertically, when the top cutting blade 25 moves, it will drive the other cutting blades 25 to move in coordination to achieve the cutting of the crop. This structural design can ensure the precise movement of the cutting blades 25 and the coordination of the cutting action, thereby improving the cutting quality and efficiency.

[0036] Finally, see Figure 2 In this embodiment, the support rods 30 of the collecting component 5 are fixedly installed on both sides of the top of the conveying frame 1. They are made of metal and are firmly connected to the conveying frame 1 by welding or bolting. The collecting rake 31 is rotatably installed between the support rods 30. The collecting rake 31 consists of metal teeth and a frame, which can effectively collect the cut crops. The fourth pulley 32 is fixedly installed on the side of the collecting rake 31. The fourth pulley 32 is connected to the second pulley 21 on one side by a second transmission belt 33. Through the transmission of the second transmission belt 33, the power of the conveying auger 17 is transmitted to the collecting rake 31, causing the collecting rake 31 to rotate, thereby collecting and transporting the crops to the collecting box and other parts. This belt drive structure is simple and reliable, which can ensure the stable operation of the collecting rake 31 and improve the collection efficiency.

[0037] Working principle:

[0038] When using the feeding device of this semi-feeding harvester, the first motor 14 is started according to the planting density and row spacing of the crops. The output shaft of the first motor 14 drives the third rotating rod 15 to rotate, the third rotating rod 15 drives the fourth rotating rod 16 to rotate, the fourth rotating rod 16 drives the second rotating rod 12 to rotate, and then drives the adjusting frame 9 to rotate around the rotating shaft 34. When the adjusting frame 9 rotates, it changes the working range and angle of the feeding device. For example, when facing sparsely planted rice fields, the adjusting frame 9 unfolds outward to widen the feeding width.

[0039] The second motor 19 is started, and its output shaft drives the first pulley 20 to rotate. The first pulley 20, through the drive rod 24, drives the second pulley 21 on one side to rotate, driving the conveyor auger 17 to rotate within the conveyor frame 1, conveying the crops to the cutting assembly 4. Simultaneously, the first pulley 20, through the first belt 23, drives the third pulley 22 on the side of the conveyor belt to rotate, causing the conveyor belt to run within the conveyor pipe 3. When the conveyor auger 17 and the conveyor belt are working, the cutting blade 25 of the cutting assembly 4 begins to work, and the drive rod 24 rotates, driving the blade in contact with it to move. The plate 29 rotates, and the rotating column 28 causes the movable plate 29, which is in contact with the vertical column 27, to push the vertical column 27 to move, which in turn causes the top cutting blade 25 to slide. Since the cutting blade 25 is staggered vertically, it works together to cut the crops. The cut crops are then transported to the subsequent processing area through the conveying pipe 3 by the conveying auger 17. At the same time, the power of the conveying auger 17 is transmitted to the fourth pulley 32 on the side of the collecting rake 31 through the second transmission belt 33, which drives the collecting rake 31 to rotate, collect the cut crops, and transport them to the collection box and other parts.
