Description

Technical Field

[0001] This utility model relates to the technical field of straw, specifically a straw turning and picking component for a straw baler. Background Technology

[0002] With the implementation of laws and regulations prohibiting the burning of crop straw in fields in my country, the rapid and clean collection and recycling of crop straw from the fields has become a critical technical issue that must be addressed first.

[0003] For example, the straw turning and picking assembly of a straw baler with authorization announcement number "CN220000086U" solves the problem that existing straw turning and picking assemblies cannot accurately put the picked-up straw into the baler, affecting the baling effect. The above-mentioned cleaning mechanism can clean the soil attached to the inner wall of the support frame to avoid soil accumulation affecting the turning effect. The picking mechanism picks up the straw and turns it into the baler. However, considering that the existing straw turning and picking assemblies turn out the straw with attached soil, it cannot guarantee that the straw is completely cleaned up, resulting in a decrease in the quality of the straw after baling. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing straw turning and picking assembly of straw balers cannot guarantee that the straw will be completely removed, resulting in a reduction in the quality of the straw after baling. Therefore, a straw turning and picking component for straw balers is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a straw turning and picking component for a straw baler, comprising an outer shell and a mounting shell, wherein the outer wall of the outer shell is fixedly connected to the mounting shell, the upper end of the outer shell is fixedly connected to a connecting rod, the end of the connecting rod is fixedly connected to a mounting plate, the surface of the mounting plate is machined with threaded holes, and a picking mechanism is connected to the inner wall of the outer shell.

[0006] This feature: The outer casing and mounting shell provide a stable mounting base for the picking mechanism and vibration mechanism. The connection between the connecting rod and the mounting plate facilitates the fixed connection of the entire device to the main body of the straw baler. The threaded holes enable quick disassembly and position adjustment, ensuring that the device remains stable during operation.

[0007] Preferably, the picking mechanism includes a round rod, the end of which is rotatably connected to the outer shell, the inner wall of which is fixedly connected to a turning rake, and the outer wall of the turning rake is machined with a through hole.

[0008] This setting: The round rod drives the rake to rotate under the drive of the second servo motor. The rake goes deep into the ground and turns the straw up from the root. During the turning process, some of the soil attached to the straw will fall off in large chunks through the long strip-shaped through holes processed on its outer wall, achieving the first soil removal and laying the foundation for further cleaning of the soil on the straw.

[0009] Preferably, the inner wall of the outer shell is fixedly connected to the arc-shaped baffle, and the inner wall of the mounting shell is connected to a vibration mechanism.

[0010] This feature: The arc-shaped baffle guides the straw stirred up by the rake, preventing it from scattering during the turning process and ensuring it falls accurately onto the inclined screen plate of the vibrating mechanism.

[0011] Preferably, the vibration mechanism includes a mounting strip, the outer wall of which is fixedly connected to a mounting shell, the inner wall of which is fixedly connected to a straight rod, the inner wall of which is slidably connected to a toggle block, the outer wall of which is connected to an inclined screen plate, and the outer wall of which is slidably connected to the mounting strip.

[0012] This feature includes: the mounting strip providing stable support for the entire vibration mechanism; the straight rod limiting the sliding direction of the actuating block, ensuring that the actuating block can only move up and down along the axial direction of the straight rod; and the inclined angle of the sieve plate being 15°-20° with the horizontal direction (gentle slope design). This ensures that the straw can eventually slide down naturally while preventing it from sliding too quickly. It also ensures that the straw slides down slowly under its own weight and that the straw makes full contact with the sieve plate during vibration, thus improving the soil removal effect.

[0013] Preferably, the inner wall of the mounting housing is fixedly connected to the first servo motor, and the output shaft of the first servo motor is fixedly connected to the push block.

[0014] This setting: The output shaft of the first servo motor drives the push block to rotate continuously at a fixed speed. The eccentric structure design of the push block allows its end to periodically contact the lower end face of the agitator block and apply downward pressure during the rotation. The output speed of the first servo motor is 300-500 r / min. Through the cooperation of the push block (10) and the agitator block (803), the vibration frequency of the inclined screen plate (804) is 5-8 times / second, ensuring that the soil and straw are fully separated.

[0015] Preferably, the outer wall of the housing is fixedly connected to the second servo motor, and the output end of the second servo motor is fixedly connected to the round rod.

[0016] This setting: The second servo motor serves as the power source for the picking mechanism, and its output end is fixedly connected to one end of the round rod via a coupling.

[0017] Preferably, the lower end of the actuating block is fixedly connected to the spring, and the lower end of the spring is fixedly connected to the mounting strip.

[0018] This feature involves the pusher rotating to disengage from the actuating block. The compressed spring generates an upward elastic restoring force, pushing the actuating block upwards along the straight rod, thereby causing the inclined screen plate to move upwards. Through the periodic downward pressure of the pusher and the elastic return of the spring, the inclined screen plate achieves continuous up-and-down reciprocating vibration.

[0019] Preferably, the inner wall of the outer shell end is rotatably connected to the baffle plate, the outer side of the baffle plate is fixedly connected to the hook, the outer wall of the hook is inserted into the chain, and the end of the chain is fixedly connected to the outer shell.

[0020] This feature: The baffle plate is rotatably connected to the inner wall of the outer casing via a hinge. The opening and closing angle can be adjusted according to the amount of straw being conveyed. The baffle plate forces the straw at the lowest end to stay on the screen plate for a certain period of time. The length of the chain can limit the maximum opening and closing angle of the baffle plate. The hook and chain can be inserted to fix and adjust the position of the baffle plate, and lift the soil clods adhering to the straw to fall off.

[0021] The present invention discloses a straw turning and picking component for a straw baler. Its advantages are as follows: The residual straw roots on the ground are lifted by the turning and rake, and the soil on the straw is discharged through the through-holes. Guided by the arc-shaped baffle, the turned straw falls onto the inclined screen plate. The first servo motor drives the push block to rotate, and the end of the push block presses down on the actuating block. The actuating block is pushed up and down by a spring at the height of the mounting strip, causing the inclined screen plate to achieve a reciprocating vibration effect, thus removing soil from the straw a second time. This ensures that most of the straw is cleaned up for baling, improving the quality of the straw baling and reducing costs. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings: Example 1: Please see Figure 1-6 In this embodiment, a straw turning and picking component for a straw baler includes a housing 1 and a mounting housing 2. The outer wall of the housing 1 is fixedly connected to the mounting housing 2. The upper end of the housing 1 is fixedly connected to a connecting rod 3. The end of the connecting rod 3 is fixedly connected to a mounting plate 4. The surface of the mounting plate 4 is machined with threaded holes 5. A picking mechanism 6 is connected to the inner wall of the housing 1.

[0025] The picking mechanism 6 includes a round rod 601. By controlling the round rod 601, the turning rake 602 is rotated, so that the turning rake 602 can pick up the straw. The end of the round rod 601 is rotatably connected to the outer shell 1, and the inner wall of the round rod 601 is fixedly connected to the turning rake 602. The outer wall of the turning rake 602 is processed with a through hole 603.

[0026] The inner wall of the outer shell 1 is fixedly connected to the arc-shaped baffle 7. The inner wall of the mounting shell 2 is connected to a vibration mechanism 8. The actuating block 803 slides up and down on the straight rod 802, so that the actuating block 803 creates an up-and-down vibration effect on the inclined screen plate 804. The vibration mechanism 8 includes a mounting strip 801. The outer wall of the mounting strip 801 is fixedly connected to the mounting shell 2. The inner wall of the mounting strip 801 is fixedly connected to the straight rod 802. The inner wall of the straight rod 802 is slidably connected to the actuating block 803. The outer wall of the actuating block 803 is connected to the inclined screen plate 804. The outer wall of the inclined screen plate 804 is slidably connected to the mounting strip 801. The remaining straw roots on the ground are lifted by the rake 602, and the soil on the straw is discharged for the first time through the through hole 603. Guided by the arc-shaped baffle 7, the straw falls onto the inclined screen plate 804. The first servo motor 9 drives the push block 10 to rotate. The end of the push block 10 presses down on the actuating block 803. The actuating block 803 is pushed up and down by the spring 12 at the height of the mounting strip 801, so that the inclined screen plate 804 achieves a reciprocating vibration effect, and removes the soil from the straw for the second time, ensuring that most of the straw is cleaned up for baling, thereby improving the quality of straw baling.

[0027] The inner wall of the mounting shell 2 is fixedly connected to the first servo motor 9. The model of the first servo motor 9 is determined according to actual needs and only needs to meet the working requirements. The output shaft of the first servo motor 9 is fixedly connected to the push block 10. The outer wall of the outer shell 1 is fixedly connected to the second servo motor 11. The model of the second servo motor 11 is determined according to actual needs and only needs to meet the working requirements. The output end of the second servo motor 11 is fixedly connected to the round rod 601. The lower end of the toggle block 803 is fixedly connected to the spring 12. The lower end of the spring 12 is fixedly connected to the mounting strip 801. The inner wall of the end of the outer shell 1 is rotatably connected to the baffle plate 13. The outer side of the baffle plate 13 is fixedly connected to the hook 14. The outer wall of the hook 14 is inserted into the chain 15. The end of the chain 15 is fixedly connected to the outer shell 1.

[0028] Working principle: Overall assembly process Foundation Fixing: First, fix the outer shell 1 and the mounting shell 2 by welding to ensure a stable connection and provide a basic framework for subsequent mechanism installation. Next, weld one end of the connecting rod 3 to the upper end of the outer shell 1 and fix the other end to the mounting plate 4. Through the threaded holes 5 on the surface of the mounting plate 4, use bolts to precisely connect the entire device to the main body of the straw baler to complete the overall fixation.

[0029] Picking mechanism installation: Connect the two ends of the round rod 601 of the picking mechanism 6 to the inner wall of the outer shell 1. Fix the rake 602 to the inner wall of the round rod 601 (the outer wall of the rake 602 is pre-machined with long slot through holes 603). Then fix the second servo motor 11 to the outer wall of the outer shell 1. Its output end is fixed to the round rod 601 through a coupling to provide power for the picking action.

[0030] Guiding and Vibration Mechanism Assembly: An arc-shaped baffle 7 is welded to the inner wall of the outer shell 1 to ensure its position guides the straw lifted by the rake 602. Then, the vibration mechanism 8 is installed. The mounting strip 801 is fixed to the inner wall of the mounting shell 2, a straight rod 802 is inserted into and fixed to the mounting strip 801, and a toggle block 803 is fitted onto the straight rod 802, with a spring 12 connected to its lower end (the other end of the spring 12 is fixed to the mounting strip 801). The inclined screen plate 804 is fixed to the outer wall of the toggle block 803 and slidably connected to the mounting strip 801. The first servo motor 9 is fixed to the inner wall of the mounting shell 2, and its output shaft is fixed to the push block 10 to ensure that the push block 10 periodically touches the toggle block 803 when rotating.

[0031] Installation of the baffle structure: The baffle plate 13 is rotatably connected to the inner wall of the end of the outer shell 1 via a hinge. The hook 14 is fixed on the outside of the baffle plate 13. One end of the chain 15 is fixed to the outer shell 1, and the other end is inserted into the hook 14. The maximum opening and closing angle of the baffle plate 13 is limited by adjusting the length of the chain 15.

[0032] Operation process Preliminary debugging: According to the specifications of the straw to be picked up, adjust the relative position of the fine-tuning device and the baler through the threaded hole 5; rotate the hook 14 to adjust the length of the chain 15, set the appropriate opening and closing angle of the baffle plate 13 to ensure that the straw can stay on the inclined screen plate 804 for a sufficient time, start the first servo motor 9 (output speed 300-500r / min), adjust the vibration frequency of the inclined screen plate 804 to 5-8 times / second, start the second servo motor 11, and check whether the turning rake 602 rotates smoothly.

[0033] Straw picking and initial soil removal: When the device moves with the baler, the second servo motor 11 drives the round rod 601 to rotate the turning rake 602. The turning rake 602 goes deep into the ground and turns the straw up from the root. Large clumps of soil attached to the straw fall off through the through hole 603 on the outer wall of the turning rake 602, thus achieving the first soil removal.

[0034] Guiding and Secondary Soil Removal: After the initial soil removal, the straw is guided by the arc-shaped baffle 7 and falls precisely onto the inclined screen plate 804 (inclination angle 15°-20°). The first servo motor 9 drives the push block 10 to rotate continuously, periodically pressing down the actuating block 803. After being compressed, the spring 12 elastically returns to its original position, causing the actuating block 803 and the inclined screen plate 804 to vibrate up and down. As the straw slowly slides down the screen plate, the residual soil is shaken off, completing the second soil removal.

[0035] Conveying and Baling: After the clean straw has been removed twice, it is fully removed by the limiting action of the baffle plate 13, and then slides down along the inclined screen plate 804 and the baffle plate 13 to the feed inlet of the baler, completing the integrated process of picking up, removing soil and conveying, and ensuring the quality of straw baling.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
