Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to a bitter bean straw baling device. Background Technology
[0002] like Figure 1 As shown, an existing straw baler mainly consists of a picking device 1, a screw feeder 2, and a compression chamber 3. The picking device 1 includes a picking roller 11 and a pressing rake 12. During the movement of the straw baler, as the picking roller 11 rotates, the hooks 13 on its surface pick up the straw on the ground. The front end of the pressing rake 12 is hinged, and the end rests on the picking roller 11, which presses down on the straw. The screw feeder 2 is arranged parallel to the rear of the picking roller 11, with an open side facing the picking roller 11 to receive the picked straw. The outlet of the screw feeder 2 is connected to the compression chamber 3. The output end of the compression chamber 3 is equipped with a binding device. The screw feeder 2 feeds the collected straw into the compression chamber 3, where it is compressed, bound, and then discharged. However, because bitter bean stalks are relatively soft, when using the straw baler, the picked-up stalks are easily stuck between the screw and the rear side wall after entering the screw feeder. Over time, this can easily cause blockages and affect smooth transmission.
[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a scientifically designed, easy-to-obstruct, and highly practical bitter bean straw baling device that facilitates smoother transport of soft straw.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a bitter bean straw baling device, comprising a picking device, a screw feeder, and a compression chamber. The screw feeder is arranged parallel to the rear of the picking device. The screw feeder includes a conveying trough and a screw disposed within the conveying trough. The conveying trough is open on one side facing the picking device to receive the straw picked up by the picking device. The output end of the screw feeder is connected to the inlet of the compression chamber. A retaining edge is installed on the side wall of the conveying trough away from the picking device. The retaining edge is positioned slightly higher than the top of the screw. The end of the retaining edge extends to the output end of the screw feeder, and the head of the retaining edge is close to the other end of the screw feeder. The retaining edge is used to deflect the straw wound by the screw back to the middle.
[0006] Based on the above, the material stop is provided with a guide arc surface on the side of the bottom facing the screw.
[0007] Based on the above, the baffle is configured to gradually widen from the head to the end.
[0008] Based on the above, the baffle is detachably mounted on the side wall of the conveying trough by a number of bolts.
[0009] Based on the above, it also includes several pads, which are used to be placed between the material stop edge and the side wall of the conveying trough. Each pad, the material stop edge, and the side wall of the conveying trough has a threaded hole with a corresponding position. The extension distance of the material stop edge can be adjusted by increasing or decreasing the number of pads.
[0010] This utility model has substantial features and advancements compared to existing technologies. Specifically, this utility model adds the aforementioned baffle edge to the traditional screw feeder. During operation, the bitter bean straw, when wound into the screw (from the bottom of the screw) on the side away from the picking device, is blocked back to the middle position by the baffle edge during its movement. This avoids the soft straw from forming a blockage at that point, making the transmission smoother. It has the advantages of scientific design, less blockage of soft straw, smoother transmission, and strong practicality.
[0011] Furthermore, the design of the guide arc surface allows the straw to turn more smoothly; during the transmission process, the closer to the output end of the screw feeder, the more straw there is, and it is easy for the straw to overflow upwards. By gradually increasing the width of the baffle edge, the overflow at the end can be reduced.
[0012] Furthermore, by setting up several bolts and several pads, the protruding position of the stop can be easily adjusted or removed according to the on-site operation conditions to achieve good operating results. Attached Figure Description

[0019] The technical solution of this utility model will be further described in detail below through specific embodiments. Example 1
[0020] like Figure 2-4 As shown, a bitter bean straw baling device includes a picking device 1, a screw feeder 2, and a compression chamber 3. The screw feeder 2 is arranged parallel to the rear of the picking device 1. The screw feeder 2 includes a conveying trough 21 and a screw 22 disposed in the conveying trough 21. The conveying trough 21 is open on one side facing the picking device 1 to receive the straw picked up by the picking device 1. The output end of the screw feeder 2 is connected to the inlet of the compression chamber 3. This part of the structure still adopts the existing straw baler.
[0021] To prevent the soft straw from getting stuck, a baffle 4 is installed on the side wall of the conveying trough 21 away from the picking device 11. The baffle 4 is set slightly higher than the top of the screw 22. The end of the baffle 4 extends to the output end of the screw feeder 2, and the head of the baffle 4 is close to the other end of the screw feeder 2. The baffle 4 is used to block the straw wound by the screw 22 back to the middle.
[0022] Working principle:
[0023] During operation, the bitter bean straw baling device is pulled forward by a traction device. The picking device 1 picks up the straw on the ground and then it is wound into the screw 22 (from the bottom of the screw). When the straw moves to the side away from the picking device 1, it is blocked by the baffle 4, changes its running direction, and is blocked back to the middle position, and continues to be pushed forward by the screw 22. This can avoid the soft straw from forming a blockage at that point, making the transmission smoother.
[0024] To make the straw turning more smoothly, a guide arc surface 41 is provided on the bottom side of the baffle 4 facing the screw 22. During the transmission process, the closer to the output end of the screw feeder 2, the more straw there is, and it is easy for the straw to overflow upwards. The baffle 4 is set to gradually widen from the head to the end to reduce the overflow at the end. Example 2
[0025] like Figure 5As shown, the difference between this embodiment and Embodiment 1 is that the bitter bean straw baling device further includes several pads 6. The baffle 4 is detachably installed on the side wall of the conveying trough 21 by several bolts 5. The pads 6 are used to place between the baffle 4 and the side wall of the conveying trough 21. Each pad 6, the baffle 4, and the side wall of the conveying trough 21 has a corresponding threaded hole. In use, the extension distance of the baffle 4 can be adjusted by increasing or decreasing the number of pads 6. During use, the operator can adjust or remove the extension position of the baffle 4 according to the on-site operation conditions to achieve a good working effect.
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
