Description

Technical Field

[0001] This application relates to the technical field of agricultural machinery, and in particular to combined straw harvesting and baling equipment. Background Technology

[0002] Straw harvesting and baling combined equipment is a device specifically designed for collecting and baling crop straw. It can automatically complete the picking, baling, and unbaling of forage, rice, wheat, and straw.

[0003] This equipment is widely used for collecting and bundling dry and green forage, rice, wheat, and corn stalks. It features a compact structure, convenient operation, and high reliability. The resulting bales are small and compact, with a loose interior and tight exterior, good air permeability, and easy transportation and storage.

[0004] However, when the straw harvesting and baling equipment collects and bales the straw and discharges it from the discharge port, the straw piles are usually rectangular. This causes the outer half of the straw pile to sway due to gravity and vibrations generated during the movement of the equipment. This results in the middle of the straw pile hitting the edge of the discharge port, causing the straw pile to break and scatter. Consequently, the straw piles produced by the equipment sometimes fail to form intact stacks. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a straw harvesting and baling combined equipment to solve the technical problem that sometimes the straw piles produced by the straw harvesting and baling combined equipment in the prior art cannot form intact straw piles.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: a combined straw harvesting and baling device, including a straw harvesting and baling machine body and an auxiliary device disposed at the discharge port of the straw harvesting and baling machine body. The auxiliary device includes a bearing plate rotatably connected to the lower end of the discharge port of the straw harvesting and baling machine body and a support spring disposed on the bottom surface of the bearing plate to support the bearing plate in a horizontal state. The bottom surface of the straw harvesting and baling machine body is provided with an L-shaped plate for supporting the support spring. One end of the support spring is connected to the bottom surface of the bearing plate, and the other end is fixedly connected to the L-shaped plate. The horizontal end of the L-shaped plate is located directly below the bearing plate.

[0007] By adopting the above technical solution, when the straw is harvested and baled by the straw harvester and discharged from the discharge port of the straw harvester and baler, the discharged straw pile will move to the support plate. This allows the portion of the straw pile discharged by the straw harvester and baler to be supported by the support plate. In this way, the straw pile will not shake or hit the edge of the discharge port of the straw harvester and baler due to gravity and the vibration generated during the combined movement of the straw harvester and baler, and the straw pile will not break or scatter. When the straw pile is completely discharged by the straw harvester and baler, it will fall onto the support plate. The support plate will rotate downwards and tilt due to the weight of the straw pile. The tilted support plate will cause the straw pile to slide down and fall onto the field, thus preventing the straw pile baled by the straw harvester and baler from breaking or scattering.

[0008] Furthermore, the upper surface of the bearing plate is provided with rotatable ball bearings.

[0009] Furthermore, the ball bearings are provided in multiple evenly distributed on the support plate.

[0010] By adopting the above technical solution, the ball bearings make it easier for the straw pile that falls onto the support plate to slide off.

[0011] Furthermore, the support plate is a retractable plate.

[0012] While the auxiliary device can prevent straw piles from breaking and scattering by adopting the above technical solution, different customers have different requirements for the size and weight of the straw piles. This means that the operator needs to adjust the size of the straw piles produced by the machine according to the customer's requirements. If the bearing plate is too long, the straw pile falling on the bearing plate cannot apply effective pressure to the end of the bearing plate away from the main body of the straw harvester and baler, which will cause the bearing plate to be unable to rotate downwards. The telescopic bearing plate solves this technical problem. By adjusting the length of the bearing plate, it can be adapted to straw piles of different sizes, thus improving the practicality and applicability of the auxiliary device.

[0013] Furthermore, both the bottom surface of the bearing plate and the bottom surface of the straw harvester and baler body are provided with adjustment structures for adjusting the position of the bearing plate supported by the support spring.

[0014] Furthermore, the adjustment structure includes a groove on the bottom surface of the support plate, an adjustment groove on the bottom surface of the straw harvester and baler body, a first slider of the support plate slidably connected through the groove, and a second slider of the straw harvester and baler body slidably connected through the adjustment groove. The vertical end of the L-shaped plate is fixedly connected to the second slider. The support spring is connected to the support plate through the first slider and is fixedly connected to the first slider.

[0015] While the retractable support plate improves the practicality and applicability of the auxiliary device by adopting the above technical solution, when the support plate is adjusted to its longer position, the position of the support spring supporting the support plate remains unchanged. This causes the end of the support plate away from the straw harvester and baler body to rotate downwards due to gravity, making it unable to support the straw pile discharged from the straw harvester and baler body. The adjustment structure solves this technical problem. When the support plate is adjusted to its longer position, the L-shaped plate slides along the support spring by sliding the second slider. The sliding support spring, through the first slider, changes its position supporting the support plate, thus preventing the end of the support plate away from the straw harvester and baler body from rotating downwards due to gravity. This allows the support plate to adapt to straw piles of different sizes, further improving the practicality and applicability of the auxiliary device.

[0016] Furthermore, a fixing device for fixing the second slider is provided on the side of the adjustment groove away from the support plate.

[0017] Furthermore, the fixing device includes a fixing plate fixedly connected to the bottom surface of the straw harvester and baler body, and a fixing screw threaded through the fixing plate and connected to the second slider.

[0018] By adopting the above technical solution, although the adjustment structure allows the bearing plate to adapt to straw piles of different sizes, the vibration generated by the straw harvester and baler body during movement may cause the second slider to slip, causing the position of the adjusted support spring to change. The setting of the fixing device solves this technical problem. After the position of the support spring is adjusted by the second slider, the fixing screw is turned so that it passes through the fixing plate and connects to the second slider, thus fixing the second slider. In this way, the second slider will not slip due to vibration.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] By incorporating auxiliary devices, when straw is harvested and baled by the straw harvester and discharged from the outlet of the straw harvester and baler, the discharged straw pile moves to the support plate. This ensures that the portion of the straw pile discharged by the straw harvester and baler is supported by the support plate. The combined force of gravity and vibrations generated during the harvesting and baling process prevents the straw pile from shaking and impacting the edge of the outlet of the straw harvester and baler, thus preventing the straw pile from breaking and scattering. When the straw pile is completely discharged by the straw harvester and baler, it falls onto the support plate. The support plate, due to the weight of the straw pile, tilts downwards, causing the straw pile to slide down and fall onto the field. This ensures that the straw pile baled by the straw harvester and baler does not break and scatter.

[0021] By setting the support plate as a telescopic plate, the length of the support plate can be adjusted to adapt to straw piles of different sizes, thereby improving the practicality and applicability of the auxiliary device.

[0022] By adjusting the structure, when the bearing plate is adjusted to a longer state, the L-shaped plate slides along the support spring by sliding the second slider. The sliding support spring changes its position supporting the bearing plate through the first slider, thereby preventing the end of the bearing plate away from the straw harvester and baler body from rotating downwards due to gravity. This allows the bearing plate to adapt to straw piles of different sizes, further improving the practicality and applicability of the auxiliary device. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Example, refer to Figure 1 , Figure 2 , Figure 3The straw harvesting and baling combined equipment includes a straw harvester and baler body 1 and an auxiliary device 2 installed at the discharge port of the straw harvester and baler body 1. The auxiliary device 2 includes a bearing plate 20 rotatably connected to the straw harvester and baler body 1 at the lower end of the discharge port, and a support spring 21 installed on the bottom surface of the bearing plate 20 to support the bearing plate 20 in a horizontal position. The bottom surface of the straw harvester and baler body 1 is provided with an L-shaped plate 22 to support the support spring 21. One end of the support spring 21 is connected to the bottom surface of the bearing plate 20, and the other end is fixedly connected to the L-shaped plate 22. The horizontal end of the L-shaped plate 22 is located directly below the bearing plate 20. When the straw is harvested and baled by the straw harvester and baler body 1, the straw is discharged from the straw harvester and baler body 1. When the straw is discharged from the outlet of the main body 1, the discharged straw pile will move onto the support plate 20. This allows the portion of the straw pile discharged by the main body 1 of the straw harvester and baler to be supported by the support plate 20. In this way, the weight and vibration generated during the combined movement of the straw harvester and baler will prevent the straw pile from shaking and hitting the edge of the outlet of the main body 1 of the straw harvester and baler, and the straw pile will not break and scatter. When the straw pile is completely discharged by the main body 1 of the straw harvester and baler, the straw pile will fall onto the support plate 20. The support plate 20 will rotate downwards and tilt due to the weight of the straw pile. The tilted support plate 20 will cause the straw pile to slide down and fall onto the field, so that the straw pile baled by the main body 1 of the straw harvester and baler will not break and scatter.

[0029] In this embodiment, a plurality of ball bearings 23 are rotatably provided on the upper surface of the support plate 20. The ball bearings 23 are evenly distributed on the support plate 20, and the ball bearings 23 make it easier for the straw pile that falls on the support plate 20 to slide off.

[0030] Although the auxiliary device 2 can prevent the straw pile from breaking and scattering, customers have different requirements for the size and weight of the straw pile. This means that the operator needs to adjust the size of the straw pile produced by the machine according to the customer's requirements. If the bearing plate 20 is too long, the straw pile falling on the bearing plate 20 cannot apply effective pressure to the end of the bearing plate 20 away from the straw harvester and baler body 1, which will cause the bearing plate 20 to be unable to rotate downwards. In order to solve this technical problem, this embodiment sets the bearing plate 20 as a telescopic plate. By adjusting the length of the bearing plate 20, the bearing plate 20 can be adapted to straw piles of different sizes, thereby improving the practicality and applicability of the auxiliary device 2.

[0031] Although the retractable support plate 20 improves the practicality and applicability of the auxiliary device 2, when the support plate 20 is adjusted to its longer state, and the position of the support spring 21 supporting the support plate 20 remains unchanged, the end of the support plate 20 away from the straw harvester baler body 1 will rotate downwards due to gravity, causing the support plate 20 to be unable to support the straw pile discharged from the straw harvester baler body 1. To solve this technical problem, in this embodiment, both the bottom surface of the support plate 20 and the bottom surface of the straw harvester baler body 1 are provided with an adjustment structure 3 for adjusting the position of the support spring 21 supporting the support plate 20. The adjustment structure 3 includes a sliding groove 30 on the bottom surface of the support plate 20, an adjustment groove 31 on the bottom surface of the straw harvester baler body 1, and a support plate slidably connected through the sliding groove 30. The first slider 32 of the L-shaped plate 20 and the second slider 33 of the straw harvester baler body 1 are slidably connected through the adjustment groove 31. The vertical end of the L-shaped plate 22 is fixedly connected to the second slider 33. The support spring 21 is connected to the support plate 20 through the first slider 32 and is fixedly connected to the first slider 32. When the support plate 20 is adjusted to a longer state, the L-shaped plate 22 slides with the support spring 21 by sliding the second slider 33. The sliding support spring 21 changes its own position supporting the support plate 20 through the first slider 32, thereby preventing the end of the support plate 20 away from the straw harvester baler body 1 from rotating downward due to gravity. This allows the support plate 20 to adapt to straw piles of different sizes, further improving the practicality and applicability of the auxiliary device 2.

[0032] Although the adjustment structure 3 allows the support plate 20 to adapt to straw piles of different sizes, the vibration generated by the straw harvester baler body 1 during movement may cause the second slider 33 to slide, resulting in a change in the position of the support spring 21 after adjustment. To solve this technical problem, in this embodiment, a fixing device 4 for fixing the second slider 33 is provided on the side of the adjustment groove 31 away from the support plate 20. The fixing device 4 includes a fixing plate 40 fixedly connected to the bottom surface of the straw harvester baler body 1 and a fixing screw 41 threaded through the fixing plate 40 and connected to the second slider 33.

[0033] Specific implementation process: Adjust the length of the bearing plate 20 and the position of the support spring 21 according to the size of the baled straw pile. After adjustment, align and screw in the fixing bolt so that it passes through the fixing plate 40 and is threaded to the second slider 33. Fix the second slider 33. When the straw pile is discharged from the discharge port of the straw harvester baler body 1, it will move onto the bearing plate 20. The bearing plate 20 supports the part of the straw pile discharged by the straw harvester baler body 1. When the straw pile is completely discharged by the straw harvester baler body 1, the straw pile will fall onto the bearing plate 20. The bearing plate 20 rotates downward and tilts due to the weight of the straw pile. The tilted bearing plate 20 causes the straw pile to slide down and fall onto the field.

[0034] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
