[0054] Third, the intermediate transmission box 18 is installed at the bottom of the transmission box 11 by bolts 127, thereby completing the installation of the disc plow. Figure 1 shown.

[0055] The beater is connected to the tractor 30 via a triangular suspension device 20; the tractor 30 serves as a power source for the disc plow, driving the transmission box 11 to rotate, thereby making the disc plow operate.

[0056] 2. The specific structure of the beater is as follows:

[0057] Specifically, the land leveling device includes a beating knife shaft 16 and a stubble burying knife shaft 17, and a third mounting plate 143 is respectively provided at both ends of the beating knife shaft 16, and a fourth mounting plate 144 is respectively provided at both ends of the stubble burying knife shaft 17; the third mounting plate 143 is fixed to the first mounting plate 125 by bolts 127; a first sprocket 14 is rotatably installed on each side plate, and a second sprocket 141 is installed at one end of a transmission shaft 132 close to the side plate, and the second sprocket 141 has a central through hole, and the central through hole of the second sprocket 141 has the same structure as the central through hole of the first gear 121, and the second sprocket 141 is sleeved on the transmission shaft 132 at this end, and the second sprocket 141 is connected to the first sprocket 14 on the same side through a chain 142; wherein each first sprocket 14 has an output shaft, one end of the output shaft passes through the side plate of this side and extends to the side plate of the other side, and a fifth mounting plate 145 is provided at the extended end of the output shaft, and the fourth mounting plate 144 and the fifth mounting plate 145 are fixed by bolts 127.

[0058] refer to Figure 6 and Figure 7 The specific installation and operation process of the beater is as follows:

[0059] First, the tilling blade shaft 15 and the middle plow assembly 18 are disassembled respectively, and then the case of the side transmission box 12 on one side is opened, and then the first gear 121, the second gear 122 and the third gear 123 on the side are disassembled in sequence.

[0060] Second, adjust the pull rod 136 and gradually extend it so that the movable half pipe 135 and the second sleeve 134 are located on a straight line, and then keep the pull rod 136 stationary.

[0061] Third, install the second sprocket 141 on the side transmission shaft 132 (that is, the installation position before the first gear 121), and then install the chain 142 on the second sprocket 141 and the first sprocket 14.

[0062] Fourth, the third mounting plate 143 at both ends of the beating knife shaft 16 is aligned with the first mounting plate 125, and fixed with bolts 127; then the fourth mounting plate 144 at both ends of the burying knife shaft 17 is aligned with the fifth mounting plate 145, and fixed with bolts 127, so as to complete the installation of the beating machine. Figure 5 shown.

[0063] The structure of the first mounting plate 125 or the second mounting plate 126 or the third mounting plate 143 or the fourth mounting plate 144 or the fifth mounting plate 145 can be referred to Figure 8 When the beater is installed, the beater blade shaft 16 needs to be installed in front of the burying shaft 17; the beater is connected to the tractor 30 through the triangular suspension device 20; the tractor 30 serves as the power source of the beater, driving the transmission box 11 to rotate, so that the beater operates.

[0064] like Fig. 9 As shown, the intelligent paddy field tillage, harrowing, stubble burying integrated land preparation machine includes a balance adjustment system, and the balance adjustment system includes a main control box, a hydraulic reversing valve, two hydraulic cylinders 22 and an angle sensor installed on the frame 10; the main control box is connected to the tractor 30 power supply, the angle sensor and the hydraulic reversing valve are electrically connected to the main control box respectively, and the two hydraulic cylinders 22 are connected to the hydraulic reversing valve; the triangular suspension device 20 includes a left connecting arm and a right connecting arm symmetrically fixed on the frame 10; the ends of the left connecting arm and the right connecting arm are respectively pinned to an adjusting arm 21, and the end of each adjusting arm 21 is movably connected to the tractor 30, and each hydraulic cylinder 22 is installed on an adjusting arm 21, and each hydraulic cylinder 22 is movably connected to the tractor 30.

[0065] Specifically, the tractor 30 is powered by the balance adjustment system, and the angle sensor is installed on the frame 10, that is, installed on the disc plow or the beater. The angle sensor is used to detect the working angle of the disc plow or the beater when working (it can be understood as detecting whether the disc plow or the beater is level with the ground). The main control box can be a microcomputer fully automatic intelligent balance controller or other equipment that can control the angle sensor and the hydraulic reversing valve.

[0066] Among them, the angle sensor and the hydraulic reversing valve have different models, and technicians can select them according to the technical solution, which is not given in detail here. Fig. 9 It is a simplified schematic diagram of the connection between a disc plow or a beater and a tractor, and other structures of the triangular suspension device 20 in the figure are not drawn.

[0067] When the tractor 30 drives the disc plow or beater to work, the tractor 30 will tilt to a lower position due to the uneven field, thereby causing the disc plow or beater to tilt. During operation, when the tractor 30 body tilts to the left (the left side of the tractor 30 body is low), the angle sensor on the disc plow or beater detects that its working angle has changed, and sends the collected signal to the main control box, which processes the received signal and issues a control instruction to control the hydraulic reversing valve to work, and then controls the two hydraulic cylinders to extend and retract relative to each other through the hydraulic reversing valve, thereby adjusting the angles of the left connecting arm and the right connecting arm to a relatively horizontal state, that is, adjusting the working angle of the disc plow or beater to a normal state. For example, when the left side of the disc plow or beater is low, the left hydraulic cylinder will rise, and the right hydraulic cylinder will drop accordingly, until the working angle of the disc plow or beater is adjusted to a horizontal state; when the right side of the disc plow or beater is low, the right hydraulic cylinder will rise, and the left hydraulic cylinder will drop accordingly, until the working angle of the disc plow or beater is adjusted to a horizontal state.

[0068] The above disclosure is only a preferred specific embodiment of the present invention, but the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
