[0002] A hay cutter is a type of agricultural machinery used to process crop straw and forage grass, and is widely used in animal husbandry. Its main function is to chop crop straw, such as corn stalks, wheat straw, and rice straw, into feed segments suitable for livestock such as cattle, sheep, and horses.

[0003] The feeding mechanism and the cutting mechanism of the grass chopper are both installed on the frame, and the frames of existing grass choppers are mostly welded, which makes it difficult to quickly disassemble and assemble the cutting mechanism when the parts are damaged and need to be repaired and replaced, which is inconvenient. Secondly, when chopping the grass, some of the juice of the grass contacts the hopper, which will cause certain corrosion to the hopper. The existing grass chopper requires the entire hopper to be replaced, which is wasteful. Utility Model Content

[0004] The technical problem to be solved by the utility model is that most of the existing grass chopper frames are welded, which makes it difficult to quickly disassemble and assemble, and it is not convenient to repair and replace parts; and when the existing grass chopper hopper is corroded and replaced, the entire hopper needs to be replaced, which is relatively wasteful.

[0005] In order to solve the above problems, the technical solution of the utility model is: an assembled grass mower frame, including a mounting frame, a supporting leg is provided at the bottom of the mounting frame, and the characteristics are: the mounting frame is a rectangular frame structure, and a partition is installed in the middle of the mounting frame by bolts, and the partition divides the mounting frame into a feeding area and a grass chopping area.

[0006] Furthermore, a motor mounting plate is mounted on the support leg at the bottom front end of the mounting frame.

[0007] Furthermore, grass baffles are installed at both ends of the grass-cutting area inside the mounting frame.

[0008] Furthermore, the connecting part includes a locking plate installed on the protective cover and a fixing frame installed on the mounting frame, a threaded column is rotatably installed on the inner side of the fixing frame, a slot adapted to the threaded column is opened on the locking plate, and a tightening knob is threadedly connected to the upper part of the threaded column.

[0009] Furthermore, a sleeve is fixedly connected to the bottom of the threaded column, a through hole is opened on the fixing frame, and a pin shaft passing through the sleeve is inserted into the through hole.

[0010] Furthermore, the hopper is formed by assembling a plurality of plates by screws, and each plate can be disassembled and replaced individually. A bending portion is provided on both sides of the baffle, and a positioning hole is provided in the middle of the bending portion. The bottom of the baffle is installed on the bottom of the hopper by rotating the shaft, and an arc groove is provided on the side of the hopper, and the arc groove matches the trajectory of the positioning hole rotating around the shaft.

[0011] Furthermore, a bolt is installed in the arc groove, the bolt passes through the positioning hole, and a nut is installed at the end of the bolt.

[0012] The advantages of the present invention over the existing technology are: the protective cover, hopper and mounting frame of the present invention are assembled and connected, and the disassembly and assembly are relatively simple, which facilitates the inspection and replacement of parts inside the grass mower; the hopper is assembled by multiple plates, and when the hopper is corroded and needs to be replaced, only the corroded plates can be replaced without replacing the entire hopper, which is more practical.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 2As shown, an assembled grass mower frame includes a mounting frame 1, a supporting leg 2 is provided at the bottom of the mounting frame 1, the mounting frame 1 is a rectangular frame structure, and a partition 3 is installed in the middle by bolts, the partition 3 divides the mounting frame 1 into a feeding area 4 and a grass chopping area 5, a motor mounting plate 10 is installed on the supporting leg 2 at the bottom of the front end of the mounting frame 1, and grass baffles 11 are installed at both ends of the grass chopping area 5 inside the mounting frame 1.

[0020] The motor can be installed at the front end of the supporting leg 2 through the motor mounting plate 10, the feeding assembly of the grass mower is installed in the feeding area 4, and the grass chopping assembly is installed in the grass chopping area 5. The feeding assembly and the grass chopping assembly are driven by the motor to work. The feeding assembly and the grass chopping assembly of the grass mower are both existing technologies and will not be repeated here.

[0021] like Figure 1 and Figure 4 As shown, the top of the mounting frame 1 is detachably connected to a protective cover 7 above the grass-cutting area 5 through a connecting piece 6. The connecting piece 6 includes a locking plate 6.1 mounted on the protective cover 7 and a fixing frame 6.2 mounted on the mounting frame 1. A threaded column 6.3 is rotatably mounted on the inner side of the fixing frame 6.2. A slot adapted to the threaded column 6.3 is provided on the locking plate 6.1. A tightening knob 6.4 is threadedly connected to the upper part of the threaded column 6.3. A sleeve 6.5 is fixed to the bottom of the threaded column 6.3. A through hole is provided on the fixing frame 6.2, and a pin 6.6 that passes through the sleeve 6.5 is inserted into the through hole.

[0022] Place the protective cover 7 above the grass-chopping area 5 on the top of the mounting frame 1 and sleeve it onto the outside of the grass-chopping assembly. Turn the threaded column 6.3 until the threaded column 6.3 rotates into the slot on the locking plate 6.1, and tighten the locking knob 6.4 to secure the protective cover 7. The provision of the connecting member 6 makes it easier to assemble and disassemble the protective cover 7, making it easier to inspect and replace the internal parts of the grass-chopping machine.

[0023] like Figure 1 and Figure 3 As shown, a hopper 8 is removably mounted to the bottom of the mounting frame 1 below the mowing area 5 via bolts. A baffle 9 is movably mounted to the rear end of the hopper 8. Baffle 9 has a bent portion on each side, and a positioning hole is defined in the middle of the bent portion. The bottom of the baffle 9 is rotatably mounted to the bottom of the hopper 8 via a rotating shaft. An arcuate groove is defined on the side of the hopper 8, matching the trajectory of the positioning hole around the rotating shaft. Bolts are installed in the arcuate grooves, which pass through the positioning holes and have nuts attached to their ends. The hopper 8 is formed by multiple plates assembled with screws, and each plate can be individually removed and replaced.

[0024] Loosening the nut allows the baffle 9 to rotate around the shaft, thereby opening the rear end of the hopper 8 and allowing for inspection and replacement of components within the hopper 8. The hopper 8 is assembled from multiple plates, each of which can be disassembled and replaced individually. This allows for targeted replacement of plates when the hopper 8 is corroded by grass juice, rather than replacing the entire hopper 8, making it more practical.

[0025] In actual use, the protective cover 7 is placed above the mowing area 5, the threaded column 6.3 is rotated until the threaded column 6.3 rotates into the slot on the locking plate 6.1, and the tightening knob 6.4 is tightened to secure the protective cover 7. The nut is loosened, and the baffle 9 rotates about the rotation axis, thereby opening the rear end of the hopper 8 and allowing the parts inside the hopper 8 to be inspected and replaced. If the hopper 8 is corroded by grass juice, only the corroded plate can be replaced, which is more practical.
