Description

Technical Field

[0001] This utility model belongs to the technical field of crop recycling equipment, specifically a new type of straw recycling machine. Background Technology

[0002] The straw recycling machine is connected to the power of a tractor and moves synchronously with the tractor to collect and crush straw in the field. The crushed straw is sprayed into the bucket or onto a loader that is moving synchronously in the field. Figure 1-4 This is a schematic diagram of the existing technology. Specifically, the crushing is accomplished by a cutting assembly consisting of a rotating shaft and a fixed blade. A hammer claw is connected to the rotating shaft, which pushes the straw towards the fixed blade as the shaft rotates, thus completing the cutting. This part of the structure is as follows: Figure 1 and Figure 2 As shown, in the prior art, the machine body is usually equipped with two sets of such cutting groups, and also with a fan blade shaft, such as... Figure 3 As shown in Figure 4, the fan blade shaft is located behind the two sets of cutting groups. The direction of movement of the straw after entering the machine body is shown by the arrow in the figure. It is gradually crushed when passing through the two sets of cutting groups. Finally, when it reaches the fan blade shaft, the fan blade shaft rotates, and the blades on it blow the crushed residue to the side, so that it is sprayed out from the discharge port on the machine body.

[0003] Based on the above, in the existing technology, since the fan blade 4 on the fan shaft is located at one end of the fan shaft, and there is usually a certain distance between one end of the fan shaft and the other end, the debris that reaches the fan shaft (especially the debris that is far away from the fan blade 4) is difficult to be sucked by the fan blade 4 when it is far away from the fan blade 4, and thus difficult to be blown out. This makes it easy for the debris to accumulate at the fan shaft, resulting in a slow material discharge speed of the machine body, and also affecting the cutting at the front end.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the following technical problems existing in the prior art: In the prior art, the blowing speed is slow due to the design of the fan shaft, which easily affects the overall working efficiency of the machine. To solve this technical problem, this utility model provides the following technical solution:

[0006] A novel straw recycling machine, the machine body having a cutting section and a conveying section, wherein:

[0007] The material passes through the cutting area and the conveying area in sequence;

[0008] The conveying section is equipped with a third shaft, fan blades, and a pusher. The fan blades and the pusher are all connected to the third shaft and are distributed sequentially along the length of the third shaft.

[0009] During the rotation of the pusher, the material is guided, and the guiding direction is consistent with the axial direction of the third shaft.

[0010] As a preferred technical solution for a new type of straw recycling machine, the third shaft includes a first position and a second position along its length direction. The second position consists of several locations and is symmetrically distributed on both sides of the first position. The fan blade is configured at the first position, and the pushing component is configured at the second position.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0030] Reference Figure 5-7 One embodiment of this utility model provides a novel straw recycling machine. The machine body has a cutting section and a conveying section. After the straw enters the machine body, it is chopped at the cutting section and then conveyed to the outside of the machine body through the conveying section. The cutting section is provided with a first cutting group and a second cutting group arranged in sequence, wherein:

[0031] The conveying unit is equipped with a third shaft 3, a fan blade 4, and a pusher 5. The third shaft 3 is rotatable. The fan blade 4 and the pusher 5 are both connected to the third shaft 3 and are distributed along the length of the third shaft 3.

[0032] During rotation, the pusher 5 can guide the accumulated material (straw fragments) and the direction of the guide is consistent with the axis of the third shaft 3.

[0033] In this invention, when recycling straw, the straw is chopped into small pieces after passing through the first and second cutting groups. When it reaches the third shaft 3, the small pieces are blown out by the rotation of the fan blades 4. The small pieces far from the fan blades 4 can be moved towards the fan blades 4 by the action of the pusher 5, so that they can be blown by the fan blades 4. This effect allows the small pieces distributed along the entire length of the third shaft 3 to be transported to the outside of the machine. Compared with the prior art, the machine can effectively prevent the accumulation of internal material residue, so the discharge speed is faster. At the same time, it avoids the impact on the front-end cutting work, so the overall harvesting efficiency of the machine is also higher.

[0034] Furthermore, the third shaft 3 can be divided into at least a first position and a second position along its length. The first position is used to set the fan blade 4, and the second position is used to set the pusher 5. Specifically, the first position is one location, and the second position is configured in several locations, symmetrically distributed on both sides of the first position. This structure allows the fan blade 4 to be located in the middle position of the third shaft 3. Therefore, when guiding the debris, the debris at both ends of the third shaft 3 moves towards the middle of the third shaft 3, thereby shortening the movement path of the debris and further increasing the efficiency of the debris being blown out of the machine body.

[0035] Furthermore, refer to Figure 6 The pushing component 5 includes at least a auger blade 501, which is fixedly connected to the third shaft 3 and is wound around the third shaft 3. When the auger blade 501 rotates with the third shaft 3, it pushes the debris.

[0036] Furthermore, refer to Figure 5 The structures of the first and second cutting groups are the same as those in the prior art. Specifically, the first cutting group includes a first shaft 1 and a first fixed blade 6, and the second cutting group includes a second shaft 2 and a second fixed blade 7. The difference between this utility model and the prior art is:

[0037] The first shaft 1 and the second shaft 2 are positioned flush, and their rotation directions are opposite, as shown below. Figure 5 As indicated by the middle arrow;

[0038] The third axis 3 is located at the horizontal midpoint between the first axis 1 and the second axis 2, and is higher than the first axis 1 and the second axis 2;

[0039] Based on the above, please refer to Figure 5 From the perspective, the straw enters the machine body from the left, and then undergoes the first cutting at the first cutting group. It is then thrown to the second shaft 2 for a second cutting. Because it is a full-size secondary crushing, the power is reduced.

[0040] Furthermore, the debris is stirred by the first shaft 1 in the clockwise direction... Figure 5 When viewed from the center position, the second axis 2 continues to stir the debris downwards in a counterclockwise direction, thereby completing the cutting at the bottom of the second axis 2. During this process, the debris is moved in the same direction as the first axis 1 and the second axis 2 continues to push it, which increases the smoothness of the debris in the entire movement process, saves the rotational power of the second axis 2, and thus reduces the overall energy consumption of the machine.

[0041] Furthermore, refer to Figure 5 In this invention, the first fixed blade 6 is positioned above the first shaft 1, while the second fixed blade 7 is positioned below the second shaft 2. After the debris is cut for the first time from above the first shaft 1, it reaches the bottom of the second shaft 2, and then passes through the right side of the second shaft 2 and reaches the third shaft 3. In this process, the distance between the first and second cuts of the debris can be shortened, thereby shortening the time interval between the two cuts, which further improves the overall cutting speed and increases the working efficiency of the machine.

[0042] Regarding the power configuration between the multiple shafts in this utility model, the first shaft 1, the second shaft 2, and the third shaft 3 are connected by a pulley assembly to form a transmission connection. A gearbox is configured on the outer shell of the machine body to connect the drive shaft of the tractor. The gearbox is configured to be connected to the first shaft 1, the second shaft 2, or the third shaft 3.

[0043] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
