Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery technology, and in particular to a silage straw baling and compacting device. Background Art

[0002] In autumn and winter, the burning of corn stalks, rice stalks, wheat stalks, soybean stalks and other polluted air often becomes the target of public criticism, which is very environmentally unfriendly. The main uses of stalks are livestock feed, living fuel or composting fertilizer. However, due to the large area of ​​​​the existing stalks, it is not convenient to collect. Many stalks are directly burned in the fields, which pollutes the air. If the stalks are placed in the fields and the stalks are shredded by machines and placed in the fields, it will affect the planting of crops in the next quarter and is not conducive to the growth of crops. The baler picking mechanism in the existing technology does not pick up the stalks thoroughly. One of the main reasons is that the bucket design is unreasonable and cannot be adjusted well according to the terrain of the field, resulting in some concave straws not being picked up cleanly and there are still a lot of residues.

[0003] According to the compaction and baling mechanism of a baler recorded in Patent No. CN201620196934.1, a baling device is provided which uses a lever to move the straw material after pre-compaction and finally achieves compaction. The structure of the pre-compaction device is relatively complex and prone to failure. The power requirements of the lever and the mechanical toughness of the lever are high. Finally, the compaction device uses a power gear to drive the connecting rod to reciprocate, which results in greater mechanical wear.

[0021] like Figure 1 As shown: Figure 1 It is a top view of the structural schematic diagram of the present invention, a silage straw baling and compacting device, comprising a crushing box 1, a pushing cylinder 2, a compacting bin 3, a control bin 4, a guide bin 5 and a slide 6;

[0023] The compacting bin 3 and the export bin 5 are both in the shape of quadrangular prisms. The left end of the compacting bin 3 is connected to the right end of the pushing cylinder 2. The right half of the compacting bin 3 overlaps with the middle part of the export bin 5 in a "T" shape. A circular filter plate 31 is provided on the rear side wall of the overlapping part of the compacting bin 3 and the export bin 5. A plurality of filter holes 32 are provided on the filter plate 31. A baffle 33, four support rods 34 and a screw rod 35 are provided in the compacting bin 3. The edges of the baffle 33 are respectively vertically attached to the upper, lower, front and rear side walls of the compacting bin 3. The four support rods 34 and the screw rod 35 are respectively vertically attached to the upper, lower, front and rear side walls of the compacting bin 3. The left end of the support rod 34 is respectively fixed to the four corners of the right side wall of the baffle 33, and the right end of the support rod 34 extends to the right to pass through the right side wall of the export bin 5, and the support rod 34 is slidably matched with the right side wall of the export bin 5. The screw rod 35 includes a smooth end on the left half and a threaded end on the right half. The left end of the screw rod 35 is rotatably connected to the center of the right side wall of the baffle 33, and a block 36 is provided on the right end of the screw rod 35. The right end of the screw rod 35 extends to the right to pass through the export bin 5, and the threaded end of the screw rod 35 is threadedly matched with the right side wall of the export bin 5.

[0024] The control compartment 4 includes a controller 41, four buffer devices 42 and a contact button 43. The left ends of the four buffer devices 42 are respectively fixed to the right ends of the four support rods 34, and the right ends of the buffer devices 42 are fixed to the right side wall of the control compartment 4. The contact button 43 is horizontally opposite to the card block 36. The contact button 43 is installed on the right side wall of the control compartment 4. The upper and lower sides of the contact button 43 are installed with card teeth 44.

[0025] The present invention is a compacting and baling device installed on a silage straw baler. Silage straw enters a pushing cylinder from a feed port and is pushed to the right end under the action of a spiral pushing rod, wherein the power of the spiral pushing rod comes from a motor. During the movement of the straw in the pushing cylinder, the straw is also cut by a first blade on the side wall, making the straw smaller, and then enters a compacting bin, which is in the shape of a quadrangular prism. More and more straw accumulates at the left end of the compacting bin and gradually moves to the right end. Under the action of a supporting rod, a baffle moves horizontally to the right, so that the straw is squeezed in the compacting bin at the left end while maintaining a certain density. During the squeezing process, a certain amount of moisture in the straw can be squeezed out, and the moisture will flow out through the filter holes of the filter plate, thereby reducing the moisture in the straw and making it more convenient to store and transport the straw bales.

[0026] like Figure 2 As shown, the crushing box 1 includes an upper material holding pocket 11 and a lower conveying path 12 , a second blade 13 is provided in the material holding pocket 11 , and a lower end opening of the conveying path 12 is communicated with the feed port 23 .

[0027] The export bin 5 comprises a push plate 51, a push rod 52 and a bin door 53. The push plate 51 and the upper side plate of the compaction bin 5 are located at the same horizontal plane. The lower end of the push rod 52 is vertically welded to the center of the upper side of the push plate 51. The upper end of the push rod 52 is linked to a power device. The bin door 53 and the lower side plate of the compaction bin 5 are located at the same horizontal plane. The left side of the bin door 53 is rotatably connected to the right side of the lower side plate of the compaction bin 5. The lower end of the export bin 53 faces the right end of the slideway 6. The left end of the slideway 6 is higher than the right end.

[0028] The right end of the support rod is provided with a buffer device, which is used to make the baffle have a certain elasticity. When the baffle is compressed after the straw is piled up, the baffle acts on the screw rod, and the screw rod is threadedly connected with the right side wall of the compacting bin to control the compression progress. When the baffle is compressed to a certain extent, the screw rod touches the contact button, and the trigger switch indicates that the straw compaction is completed. The contact button starts the controller, and the program of the controller is triggered. First, the latch teeth are engaged with the block to make the baffle lose the force to the left, and then the motor is controlled to stop, the pushing cylinder stops feeding, and finally the power device is started to push the pushing rod, which pushes the pushing plate to move downward, pushes the formed straw bale to the slide, and slides out of the baling and compacting device on the slide; when a series of program actions are completed, the next baling is completed again. It should be noted that when the present invention is performing the next baling, when the latch teeth release the block, due to the threaded end of the screw rod being threadedly matched with the right side wall of the compacting bin, the baffle can be slowly released to reset to the left while the screw rod is rotating.

[0029] like Figure 3 As shown: the buffer device 42 includes a spring slot 421 and a spring 422 , the spring 422 is installed in the spring slot 421 , one end of the spring 422 is fixedly connected to the support rod 34 , and the other end of the spring 422 is fixedly connected to the bottom of the spring slot 421 .

[0030] Before baling and compacting, the compacting and baling device of the present invention has already preliminarily crushed the silage straw.
