DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] See also Figure 1-8 One embodiment of the present invention is: an automatic agricultural straw baling device, comprising a baling box 1, and further comprising:

[0056] A lower hopper 2 is installed on the top right side of the baling box 1 and is used to transfer the straw to the inside of the baling box 1;

[0057] The material conveying mechanism 3 is arranged inside the baling box 1 and is used for conveying the straw for baling;

[0058] A coiling drum 4 is installed inside the baling box 1 at the other side of the feeding mechanism 3 and is used to roll up the delivered straw;

[0059] The scraping mechanism 5 is arranged inside the baling box 1 and below the feeding mechanism 3, and is used to scrape off the straw attached to the feeding mechanism 3;

[0060] A baling mechanism 6, arranged on the baling box 1, for baling the straw dropped from the coiling drum 4;

[0061] Wherein, the bundling mechanism 6 comprises:

[0062] A lower material barrel 61 is mounted on the baling box 1 and is located below the coiling barrel 4;

[0063] Two arc-shaped clamping plates 62 are installed on both sides of the lower barrel 61 and move into the lower barrel 61 to clamp the straw;

[0064] Two electric telescopic rods 63 are installed on the lower barrel 61 through a base, and the output ends thereof are connected to a connecting rod 64 and are movably connected in the arc clamping plate 62 to push the arc clamping plate 62;

[0065] The arc-shaped clamping plate 1 67 and the arc-shaped clamping plate 2 68 are respectively installed inside the arc-shaped clamping plates 62 on both sides;

[0066] The push rod 65 is movably connected to the inner wall of the arc clamping plate 62, and its inner side is in contact with the arc clamping plate 1 67 and the arc clamping plate 2 68;

[0067] The first spring 66 is mounted on the inner wall of the arc-shaped clamping plate 62 and is connected to the push rod 65 and the connecting rod 64 .

[0068] There are two groups of connecting rods 64, push rods 65 and first springs 66, respectively. The ends of the two lower connecting rods 64 away from the arc-shaped clamping plates 62 are movably inserted into the movable holes provided on the base. A concave groove is provided on the arc-shaped clamping plate 2 68, and a T-shaped block is provided on the arc-shaped clamping plate 1 67, and the T-shaped block is clamped in the concave groove to fix the straw.

[0069] A through hole is provided in the arc-shaped clamping plate 62 , and a conical stopper rod 610 is connected in the through hole via a second spring 69 , so as to limit the arc-shaped clamping plate 2 68 and the arc-shaped clamping plate 1 67 from being separated from the arc-shaped clamping plate 62 .

[0070] Working principle: When the straw falls from the lower hopper 2 into the feeding mechanism 3, the straw is transferred to the winding drum 4 along the feeding mechanism 3, and the straw is dropped through the funnel-shaped winding drum 4, and then the straw is led out through the lower feeding drum 61. At this time, when the straw falls and touches the blocking mechanism 7, the electric telescopic rod 63 is controlled by the controller to move, and the connecting rods 64 on both sides are pulled to move, thereby shortening the distance between the two sides. At this time, the arc clamping plates 62 are pushed closer to each other through the connecting rods, and the fallen straw is gathered together, and the push is continued, by continuing to squeeze the first spring 66 and continue to push the push rod 6 5 moves, thereby pushing the arc-shaped clamping plate 1 67 and the arc-shaped clamping plate 2 68 to approach each other. When the arc-shaped clamping plate 1 67 and the arc-shaped clamping plate 2 68 are close to each other and fit together, under the action of the thrust, the T-shaped clamping block on the arc-shaped clamping plate 1 67 is directly clamped in the concave groove of the arc-shaped clamping plate 2 68 to achieve clamping, thereby fixing the arc-shaped clamping plate 1 67 and the arc-shaped clamping plate 2 68 together to achieve compression and fixation of the straw, and by resetting the electric telescopic rod 1 63, the force on the arc-shaped clamping plate 62 is released, and the blocking mechanism 7 is removed at the same time, so that the straw that is bundled and fixed by the arc-shaped clamping plate 1 67 and the arc-shaped clamping plate 2 68 can fall down.

[0075] A discharge port is provided on the lower left side of the lower hopper 2, and a baffle 21 is hinged at the discharge port, and the baffle 21 is in contact with the paddle 33 to push the baffle 21 to rotate and transfer the straw.

[0076] The material conveying mechanism 3 also includes:

[0077] The upper pressing plate 34 is connected to the top of the inner wall of the baling box 1 through two elastic telescopic rods 38;

[0078] A plurality of pressing blocks 35 are mounted on the bottom of the upper pressing plate 34;

[0079] The extrusion shaft 36 has two ends rotatably connected to the inner wall of the baling box 1 through bearings, and one end of the back side movably penetrates the baling box 1 and extends to the outside of the baling box 1, and is connected to the two material transfer shafts 31 through a pulley set. A motor is installed on the outer wall of the baling box 1, and its output end is connected to the extrusion shaft 36 to drive the extrusion shaft 36 and the two material transfer shafts 31 to rotate synchronously;

[0080] The elliptical squeezing rod 37 is fixedly sleeved on the outer wall of the squeezing shaft 36, and its outer wall is in contact with the top of the upper pressing plate 34, and is used to push the upper pressing plate 34 downward to squeeze the straw on the conveyor belt 32 through the pressing block 35;

[0081] The support plate 39 is connected to the inner wall of the baling box 1 and is located inside the conveyor belt 32 , and is used to support the upper pressing plate 34 .

[0082] Working principle: When the straw falls along the lower hopper 2, it is blocked by the paddle 33 installed on the conveyor belt 32, and it contacts the baffle 21 intermittently, thereby opening the feed port and releasing the straw in the lower hopper 2 onto the conveyor belt 32, and controlling the speed at which the straw falls onto the conveyor belt 32. When the conveyor belt 32 is being transported, the extrusion shaft 36 driven by the motor connected to the outer wall of the baling box 1 rotates, thereby driving the elliptical extrusion rod 37 to rotate, which continuously squeezes the upper pressing plate 34 downward, thereby continuously squeezing the straw through the pressing block 35 at the bottom, so as to achieve the function of compacting the straw, so as to facilitate auxiliary baling.

[0083] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the scraping mechanism 5 includes:

[0084] The scraper 51 is hinged to the inner wall of the baling box 1 and is pushed by a coil spring to fit the outer wall of the conveyor belt 32;

[0090] The second electric telescopic rod 71 is connected to the lower base, and its output end is hinged to the lower side of the connecting plate 72.

[0091] Working principle: When the compacted straw is transferred to the winding drum 4, it is scraped by the scraper 51 to prevent the straw from adhering to the conveyor belt 32. When the paddle 33 rotates with the conveyor belt 32, it contacts the paddle 52 and pushes the scraper 51 to rotate in the opposite direction along its hinge point to move the straw downward. At the same time, after rotating away from the scraper 51, the inner scraper 53 flips along the internal hinge point and continues to contact the conveyor belt 32 to achieve the scraping effect.
