Description

Technical Field

[0001] The invention belongs to the technical field of straw compression and baling, and in particular relates to a large square straw bale picking and baling machine. Background Art

[0002] In order to reduce transportation costs, the straw must be compressed into bales before leaving the ground. The bale shapes mainly include round bales and square bales. Square bales are divided into large square bales and small square bales. Due to the small square bale baler, the bale size is small, so the work efficiency is low. The large square bale baler has high work efficiency and its transportation space utilization rate is also high compared to the round bale baler. It is an ideal way to handle straw off the ground.

[0003] Round bales contain a lot of soil during the picking process, and a lot of cultivated soil is taken away during transportation, causing irreversible damage to the cultivated land; while large square bale balers are mainly imported equipment, they mainly use spring teeth to pick up and feed down, although this type of picking has a lower soil content, but the picking is not as thorough as the hammer claw type. In addition, the compression of large square bales is compressed by a crank slider, the baler has many moving parts, a complex structure, and high maintenance costs. Summary of the invention

[0043] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0044] like Figures 1 to 10 As shown, the present invention provides a large square bale straw picking and baling machine, including: a frame 100, a picking mechanism 200, a chopping mechanism 300, a fan conveying mechanism 400, a rotating screen 500, a silo 600, a compression mechanism 700 and a knotter 800.

[0045] A plurality of wheels 110 are provided below the frame 100 to facilitate straw processing operations by traction by a tractor, and to facilitate the traction and transportation of the large square bale straw picking and baling machine by a vehicle.

[0046] The picking mechanism 200 is fixedly mounted below the frame 100 and is arranged near the front end (one end connected to the tractor or the towing vehicle) of the frame 100. The picking mechanism 200 adopts a hammer claw type picking mechanism to ensure the thorough picking of the straw.

[0047] The shredder mechanism 300 is fixedly installed under the frame 100, and the feed port of the shredder mechanism 300 is arranged toward the picking mechanism 200, and is used to receive the straw picked up by the picking mechanism 200. The shredder mechanism 300 is used to shred the picked up straw, and the outer cover of the shredder mechanism 300 is provided with a cylindrical screen, and the dust carried in the straw can fall back into the cultivated land through the cylindrical screen.

[0048] The inlet end of the fan conveying mechanism 400 is connected to the discharge port of the shredding mechanism 300. The fan conveying mechanism 400 is composed of a fan and a curved conveying cylinder 410; one end of the conveying cylinder 410 is connected to the discharge port of the shredding mechanism 300, and the other end is connected to the feed port of the rotary screen 500; the chopped straw is sent into the rotary screen 500 through the conveying cylinder 410 by the hoisting of the fan. Among them, the top of the conveying cylinder 410 is provided with a plurality of dust discharge holes 411 arranged in an array near the feed port of the rotary screen 500. The dust carried in the straw can be further discharged through the dust discharge holes 411 during the air conveying process.

[0049] In this embodiment, two fan conveying mechanisms 400 are provided, and the two fan conveying mechanisms 400 are respectively provided at two ends of the chopping mechanism 300. Providing two fan conveying mechanisms 400 can improve the conveying efficiency of the straw, thereby improving the working efficiency of the entire baler.

[0050] The picking structure 200, the shredding mechanism 300 and the fan of the fan conveying mechanism 400 are all powered by the rear output shaft of the tractor, and the power is transmitted through mechanical transmission (such as a belt).

[0051] The rotating screen 500 is arranged above the frame 100 and is arranged along the longitudinal direction (length direction) of the frame 100. The rotating screen 500 includes a cylindrical screen 510, a screw conveying shaft 520 and a driving device; the screw conveying shaft 520 is coaxially arranged in the cylindrical screen 510. Among them, the screw conveying shaft 520 is composed of a rotating shaft and a spiral blade spirally wound on the rotating shaft. The power output shaft of the driving device is connected to the screw conveying shaft 520, driving the screw conveying shaft 520 to rotate, thereby pushing the straw in the rotating screen 500 to move. In the process of the straw being pushed by the bolt conveying shaft 520, the dust carried in the straw falls from the cylindrical screen 510 and returns to the cultivated land. Among them, a connecting cover 530 is provided at the feed inlet of the rotating screen 500, and openings are respectively provided at both ends of the connecting cover 530, and the outlet ends of the two conveying cylinders 410 are respectively connected through the openings.

[0052] The compression mechanism 700 is fixedly arranged on the frame 100 and arranged in the longitudinal direction of the frame 100. A feed port is provided at the top of the cavity of the compression mechanism 700. A silo 600 is fixedly arranged above the cavity of the compression mechanism 700, and the feed port of the silo 600 is communicated with the discharge port of the rotary screen 500; a discharge port is provided at the lower end of the silo 600, and the discharge port is communicated with the feed port of the cavity of the compression mechanism 700.

[0053] In this embodiment, the feed port of the silo 600 is disposed on the side wall of the front side of the silo 600 and is disposed close to the top of the silo 600. The rotating screen 500 is disposed horizontally, so the rotating screen 500 is also located above the compression mechanism 700.

[0054] As a preferred embodiment, the compression mechanism 700 adopts a hydraulic compression mechanism. The hydraulic cylinder 710 of the compression mechanism 700 is connected to the compression push plate 720, and the hydraulic cylinder 710 pushes the compression push plate 720 to move in the cavity of the compression mechanism 700 to achieve the compression of the straw. Compared with the crank compression mechanism, the hydraulic compression mechanism has a simple structure and is easy to control.

[0055] As a further preference, a serrated first cutter 610 is fixedly provided at the rear end of the discharge port of the silo 600; a second cutter 730 opposite to the first cutter 610 is provided at the upper end of the compression push plate 720. When the compression push plate 720 moves, the first cutter 610 and the second cutter 730 move relative to each other, thereby cutting off the straw blocking the discharge port of the silo 600 and ensuring the smooth movement of the compression push plate 720.

[0056] The inlet end of the knotter 800 is connected to the discharge port of the compression mechanism 700, and is used to bundle the compressed straw. As a preferred embodiment, the knotter 800 is driven by a hydraulic motor.

[0057] Preferably, the baler is further provided with an anti-piling device 900, which is arranged near the rear side of the silo 600 and is mounted on the top plate of the cavity of the compression mechanism 700 through a bracket. The anti-piling device 900 includes: a baffle 910 and a baffle driving mechanism 920. The size of the baffle 910 matches the cross-sectional size of the cavity of the compression mechanism 700; a slit-shaped opening is opened horizontally along the frame 100 at the top of the cavity of the compression mechanism 700, and the baffle 910 can enter the cavity of the compression mechanism 700 from the slit-shaped opening under the drive of the baffle driving mechanism 920 to block the straw falling from the silo 600. When the push plate of the compression mechanism 700 moves backward along the frame 100 to perform the compression operation, the baffle 910 moves upward and retreats to the top of the cavity of the compression mechanism 700. When the baffle of the compression mechanism 700 moves forward and back along the frame 100 after completing the compression operation in sequence, the baffle 910 enters the cavity of the compression mechanism 700, and the broken straw falling from the silo 600 is blocked by the baffle, preventing the broken straw from accumulating at the bottom of the cavity of the compression mechanism 700, causing the top of the compressed straw bale to be loose, thereby ensuring the uniformity of straw compression.

[0058] In this embodiment, the baffle driving mechanism 920 includes a hydraulic motor and a nut-screw mechanism, the screw of the nut-screw mechanism is connected to the output shaft of the hydraulic motor, and the nut is connected to the baffle 910 .

[0059] As a further preference, the baler is also provided with two sets of anti-falling mechanisms, which are symmetrically arranged on both sides of the discharge port of the compression mechanism 700; wherein the anti-falling mechanism includes a plurality of anti-falling rods 710 arranged at intervals in the vertical direction, one end of the anti-falling rod 710 extends into the cavity of the compression mechanism 700, and the other end is connected to the side wall of the cavity of the compression mechanism 710 through a torsion spring. Since the straw needs to be compressed and formed multiple times, the anti-falling rod 710 can prevent the uncompressed straw from falling forward. After the compression is completed, due to the pushing action of the compression mechanism 700, the straw bale moves backward, squeezing the falling rod 710 outward, so that the anti-falling rod 710 flips around the torsion spring, and no longer hinders the movement of the straw bale.

[0060] The rotating screen 500, the compression mechanism 700, the knotter 800 and the anti-piling device 900 in the large square bale straw picking and baling machine are all powered by a tractor. The power output by the rear output shaft of the tractor is converted by a hydraulic station to provide power for the rotating screen 500, the compression mechanism 700, the knotter 800 and the anti-piling device 900.

[0061] The working process of the large square straw bale picking and baling machine provided by the present invention is as follows: the straw on the cultivated land is sent to the shredding mechanism 300 after being picked up by the picking mechanism 200, and the shredding straw of the shredding mechanism 300 is transported to the rotating screen 500 through the fan conveying mechanism 400, and the spiral conveying shaft 510 of the rotating screen 500 pushes the straw to move, so that the straw enters the silo 600, and the baffle 910 of the anti-piling device 900 descends into the cavity of the compression mechanism 700 during the unloading process of the silo 600; the baffle 910 of the anti-piling device 900 rises at the same time when the compression mechanism 700 is started, and after multiple unloading and extrusion, the straw is formed. During the process of the compression mechanism 700 compressing the straw, the formed straw is pushed forward to enter the knotter 800, and after the knotter 800 ties the straw, the next compressed and formed straw bale pushes the tied straw bale out of the outlet 810 of the knotter 800. During the operation of the compression mechanism 700 , the first straw bale that has been bundled stays in the knotter 800 until the next straw bale is pushed out and squeezed out of the knotter 800 .

[0062] The large square bale straw picking and baling machine provided by the present invention adopts a top feeding method. Before compression, the dust carried in the straw is fully screened out by the rotating screen 500. At the same time, with the help of the cylindrical screen outside the chopping mechanism 200 and the dust exhaust holes on the fan conveying mechanism 400, the dust carried by the straw can be fully discharged, thereby preventing the straw from taking away a large amount of cultivated soil and protecting the cultivated land; and the straw bales are made cleaner and can be directly used as roughage.

[0063] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
