Description

Technical Field

[0001] The utility model relates to the technical field of sand-fixing grass landfill, in particular to a bundle breaking device for sand-fixing grass landfill. Background Art

[0002] In desert areas, in order to prevent wind and fix sand, wheat straw, rice straw, reeds and other materials are usually used to fill the mobile sand dunes into a grid-shaped windbreak wall to weaken wind erosion. At present, some grass burying machines have appeared on the market, mainly including a storage tank box, which mainly stores straw bales or loose straw stalks. A toothed roller is set at the bottom outlet of the storage tank box, and the grass in the storage tank is pushed back and spread on the sand by the toothed roller, and then pressed into the sand by a grass pressing wheel. This type of equipment has the following problems in actual use: 1. The grass bales or grass stalks in the grass storage box fall onto the toothed roller by their own gravity. Therefore, when the toothed roller rotates, the toothed roller may not be able to separate the grass stalks from the grass bales, or the grass stalks may become arched, making it difficult to ensure the amount of grass moved out by the toothed roller, thus affecting the effect of burying grass and fixing sand; 2. This type of equipment is mainly suitable for round bales. When the toothed roller moves the grass stalks, the round bale will rotate to achieve continuous unloading of the circumference of the bale, but it is not suitable for square bales. The various surfaces of the square bale are flat and have edges and corners. Therefore, when the toothed roller moves the square bale, the square bale is not easy to rotate and requires continuous manual adjustment, which seriously affects the efficiency and effect of burying grass. Utility Model Content

[0003] The utility model aims to provide a bale breaking device for sand fixation and grass burying with high working efficiency.

[0004] The utility model is implemented by the following technical scheme: a bale breaking device for sand-fixing and grass-burying, which comprises a frame, two side baffles arranged opposite to each other are arranged on the top of the frame, a bale pressing mechanism and a bale breaking mechanism arranged front and back are arranged between the two side baffles, the bale pressing mechanism comprises an arc-shaped pressing frame arranged toward the bale breaking mechanism, the bottom end of the arc-shaped pressing frame is hinged to the frame or the side baffles at the front end of the bale breaking mechanism, and a pressing hydraulic cylinder driving the arc-shaped pressing frame to rotate toward the bale breaking mechanism is arranged on the frame; the bale breaking mechanism comprises a first material-discharging roller and a second material-discharging roller which are arranged in parallel front and back and rotate backward, and the second material-discharging roller is arranged above and behind the first material-discharging roller, and the axis of the first material-discharging roller is arranged perpendicularly to the rotation direction of the arc-shaped pressing frame.

[0005] Furthermore, the clamping hydraulic cylinder is arranged at the front end of the arc-shaped pressing frame, the bottom end of the clamping hydraulic cylinder is hinged to the frame, and the top end of the clamping hydraulic cylinder is hinged to the arc-shaped pressing frame.

In addition, when terms such as "first", "second", "third" appear, they are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0014] Such as Figures 1 to 2As shown in the figure, a bale-breaking device for fixing sand and burying grass includes a frame 1. At the top of the frame 1, there are two relatively arranged side baffles 4. Between the two side baffles 4, there are a bale pressing mechanism 2 and a bale-breaking mechanism 3 arranged front and back. A placement space for placing bales is formed among the bale pressing mechanism 2, the bale-breaking mechanism 3 and the two side baffles 4. The bale pressing mechanism 2 includes an arc-shaped pressing frame 21 facing the bale-breaking mechanism 3. The bottom end of the arc-shaped pressing frame 21 is hinged to the frame 1 or the side baffle 4 at the front end of the bale-breaking mechanism 3. In this embodiment, the arc-shaped pressing frame 21 is hinged to the side baffle 4. On the frame 1, there is a pressing hydraulic cylinder 22 for driving the arc-shaped pressing frame 21 to rotate towards the bale-breaking mechanism 3. The pressing hydraulic cylinder 22 is arranged at the front end of the arc-shaped pressing frame 21. The bottom end of the pressing hydraulic cylinder 22 is hinged to the frame 1, and the top end of the pressing hydraulic cylinder 22 is hinged to the arc-shaped pressing frame 21. When the piston rod of the pressing hydraulic cylinder 22 retracts, the arc-shaped pressing frame 21 can rotate away from the bale-breaking mechanism 3, and then the bale can be placed between the arc-shaped pressing frame 21 and the bale-breaking mechanism 3. During the grass burying operation, by controlling the piston rod of the pressing hydraulic cylinder 22 to continuously extend, the arc-shaped pressing frame 21 can be rotated towards the bale-breaking mechanism 3, and then the bale can be pressed on the top of the bale-breaking mechanism 3.

[0015] The bale-breaking mechanism 3 includes a first feeding roller 31 and a second feeding roller 32 which are arranged parallel to each other front and back and rotate backward. The second feeding roller 32 is arranged behind and above the first feeding roller 31. The axis of the first feeding roller 31 is arranged perpendicular to the rotation direction of the arc-shaped pressing frame 21. The structures of the first feeding roller 31 and the second feeding roller 32 are the same. The second feeding roller 32 includes a feeding roller main body 33 and a number of tooth discs 34 fixed at intervals on the outer wall of the feeding roller main body 33. On the outer wall of the feeding roller main body 33 between adjacent tooth discs 34 on the first feeding roller 31, there is a scraping plate 35 arranged along the axis of the feeding roller main body 33. The scraping plate 35 is arranged along the axis of the feeding roller main body 33, which can increase the contact area and friction force with the bale. During the rotation of the first feeding roller 31, the bale above it can be pushed to rotate through the scraping plate 35. Especially for square bales, the corners of the square bales can be pushed through the scraping plate 35 to drive the whole square bale to rotate. When breaking the bale, first, the first feeding roller 31 is used to push the bale to rotate, and then the second feeding roller 32 is used to dial the straw rods on the bale backward and spread them on the sand surface to complete the straw spreading operation. The cooperation of the first feeding roller 31 and the second feeding roller 32 realizes the operation process of first rotating the bale and then dialing the forage, achieving the purpose of uniform forage spreading. Between the rear ends of the two side baffles 4, there are several unloading teeth 5 whose tooth tips are in sliding contact with the feeding roller main body 33 of the second feeding roller 32. The straw rods dialed out by the second feeding roller 32 are unloaded through the unloading teeth 5.
