Once the soil and water are lifted to the upper end of the cylinder, they are transported through the discharge pipe and ultimately to the feed port, completing the automatic soil loading process and effectively reducing the user's labor intensity.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention provides a technical solution for a semi-automatic self-propelled rice seedling beating screening and filtering machine, comprising a frame 2, a floating plate 1 fixedly mounted on the bottom of the frame 2, a handrail 5 fixedly mounted on the frame 2, a handle 3 fixedly mounted on the end of the handrail 5, a shift lever 4 mounted on the handle 3, a driving mechanism 9 mounted on the frame 2, a beating mechanism 6 fixedly mounted on the front edge of the frame 2, a material receiving mechanism 7 fixedly mounted on one side of the floating plate 1, and a feeding mechanism 8 mounted between the material receiving mechanism 7 and the beating mechanism 6. like Figure 2 and Figure 3 As shown, the drive mechanism 9 includes a diesel engine 901 and a gear box 906 fixedly mounted on the frame 2, a main pulley 902 is fixedly mounted on the output end of the diesel engine 901, a second pulley 905 is fixedly mounted on the input end of the gear box 906, a first belt 903 and a second belt 904 are connected to the main pulley 902, a movable pulley 907 is fixedly mounted on the output end of the gear box 906, one end of the first belt 903 is connected to the main pulley 902, and the other end of the first belt 903 is connected to the second pulley 905, one end of the second belt 904 is connected to the main pulley 902, and the other end of the second belt 904 is connected to the first pulley 604, the diesel engine 901 is provided with bolts, and the diesel engine 901 is fixedly mounted on the frame 2 by bolts.

[0022] Specifically, when diesel engine 901 is started, it begins to rotate main pulley 902. As main pulley 902 rotates, it further drives first belt 903 and second belt 904 to begin rotating. Once first belt 903 begins rotating, it transmits power to the gear train within gearbox 906, causing these gears to rotate. The rotation of the gear train, in turn, drives movable pulley 907, ultimately causing the entire device to move.

[0023] like Figure 3 、 Figure 4 and Figure 5 As shown, the beating mechanism 6 includes a mechanism shell 601 fixedly mounted on the frame 2, a feed port 602 fixedly mounted on the upper end of the mechanism shell 601, a discharge port 606 fixedly mounted on the lower end of the mechanism shell 601, a filter plate 607 connected to the discharge port 606, a drive shaft 605 rotatably mounted in the mechanism shell 601, a blade 603 fixedly mounted on the drive shaft 605, a first pulley 604 fixedly mounted at the end of the drive shaft 605, bearings are mounted at both ends of the mechanism shell 601, the drive shaft 605 is rotatably mounted in the mechanism shell 601 through the bearings, the blade 603 is rotatably mounted in the mechanism shell 601 through the drive shaft 605, a slot is provided on the discharge port 606, and the filter plate 607 is mounted on the discharge port 606 through the slot.

[0024] Specifically, when the soil is transported to the feed port 602, it will fall into the mechanism housing 601. Subsequently, the second belt 904 starts to operate, driving the first pulley 604 to rotate. The rotation of the first pulley 604 will be further transmitted, causing the drive shaft 605 to rotate at high speed. During the high-speed rotation of the drive shaft 605, it will drive the blades 603 to rotate at high speed in the mechanism housing 601. The ultimate goal of this series of actions is to break up the soil and mix it into a uniform slurry. After completing this process, the mud will be discharged through the discharge port 606. During the discharge process, the filter plate 607 will filter the mud to ensure that the discharged mud meets the required purity standard.

[0025] like Figure 6 and Figure 7As shown, the material receiving mechanism 7 includes a retaining frame 703 fixedly mounted on one side of the frame 2 and a material receiving box 704 fixedly mounted on one side of the floating plate 1, a transmission shaft 702 is rotatably mounted on the retaining frame 703, a rotating shaft 705 is rotatably mounted on the front end of the material receiving box 704, an excavation disc 707 is fixedly mounted on the rotating shaft 705, a helical gear 706 is fixedly mounted on one end of the rotating shaft 705, helical gears 701 are fixedly mounted on both ends of the transmission shaft 702 and in the middle of the main pulley 902, a bearing is installed in the retaining frame 703, the transmission shaft 702 is rotatably mounted on the retaining frame 703 through the bearing, the helical gear 701 at the upper end of the transmission shaft 702 is meshed with the helical gear 701 in the middle of the main pulley 902, the helical gear 701 at the lower end of the transmission shaft 702 is meshed with the helical gear 706, and the excavation disc 707 is rotatably mounted on the front end of the material receiving box 704 through the rotating shaft 705.

[0026] Specifically, when the material receiving box 704 starts to move, the bevel gear 701 located on the main pulley 902 will engage with the bevel gear 701 at the upper end of the drive shaft 702. This meshing relationship enables the drive shaft 702 to rotate as the main pulley 902 rotates. The rotation of the drive shaft 702 is a key step because it will further transmit power to the bevel gear disc 706. Driven by the drive shaft 702, the bevel gear disc 706 also begins to rotate, and its rotation drives the rotating shaft 705 connected to it. The rotation of the rotating shaft 705 drives the excavation disc 707 to rotate, and this rotational action enables the excavation disc 707 to penetrate deep into the field and excavate the soil. As the excavation disc 707 continues to rotate, it transports the excavated soil into the material receiving box 704, completing the entire excavation and collection process.

[0027] like Figure 6 and Figure 8 As shown, the feeding mechanism 8 includes a positioning bracket 806 fixedly mounted on the frame 2, a positioning sleeve 805 fixedly mounted on the positioning bracket 806, a lifting cylinder 803 fixedly mounted on the positioning sleeve 805, a motor 801 fixedly mounted on the upper end of the lifting cylinder 803, a movable shaft 802 fixedly mounted on the output end of the motor 801, a spiral conveying rod 804 fixedly mounted on the end of the movable shaft 802, a discharge pipe 807 fixedly mounted on the upper end edge of the lifting cylinder 803, and the discharge pipe 807 is aligned with the feed port 602 up and down, the lifting cylinder 803 is fixedly mounted on the positioning bracket 806 through the positioning sleeve 805, and the lifting cylinder 803 is installed on one side of the frame 2 through the positioning bracket 806, one end of the movable shaft 802 is fixedly mounted on the output end of the motor 801, and the other end of the movable shaft 802 is fixedly mounted on the spiral conveying rod 804.

[0028] Specifically, after the motor 801 is started, it will begin to operate and drive the movable shaft 802 to rotate. During the rotation of the movable shaft 802, it will further prompt the spiral conveying rod 804 to rotate inside the lifting cylinder 803. This series of mechanical actions enables the soil and water in the material receiving box 704 to be effectively transported to the upper end position of the lifting cylinder 803. Once the soil and water reach the upper end of the lifting cylinder 803, they will flow into the discharge pipe 807. As the soil and water flow, they will eventually be transported to the position of the feed port 602 by the discharge pipe 807. The automatic feeding function of the soil is realized, which greatly reduces the labor intensity of the user.

[0029] Working Principle: When in use, the diesel engine 901 is first started. After starting the diesel engine 901, it drives the main pulley 902 to rotate. After the main pulley 902 rotates, it drives the first belt 903 and the second belt 904 to rotate. After the first belt 903 rotates, it drives the gear set in the gear box 906 to rotate, thereby driving the movable wheel 907 to rotate, making the entire device move. When the entire device moves, the material receiving box 704 moves along with the floating plate 1. When the material receiving box 704 moves, the bevel gear 701 on the main pulley 902 drives the bevel gear 701 on the upper end of the transmission shaft 702 to rotate, thereby rotating the transmission shaft 702. After the transmission shaft 702 rotates, it drives the bevel gear plate 706 to rotate. After the bevel gear plate 706 rotates, it drives the rotating shaft 705 to rotate. After the rotating shaft 705 rotates, it drives the excavation disc 707 to rotate. During the rotation of the excavation disc 707, the soil in the field is excavated and transported to the material receiving box 704. After the excavated soil is transported to the material receiving box 704, the motor 801 can be started. After starting the motor 801, it will drive the movable shaft 802 to rotate. After the movable shaft 802 rotates, it will drive the spiral conveying rod 804 to rotate in the lifting cylinder 803, thereby transporting the soil and water in the material receiving box 704 to the upper end of the lifting cylinder 803. After the soil and water are transported to the upper end of the lifting cylinder 803, they will enter the discharge pipe 807. The soil and water in the discharge pipe 807 will eventually be transported to the feed port 602, realizing automatic loading of soil and reducing the labor intensity of users. The soil transported to the feed port 602 will fall into the mechanism housing 601. After the soil falls into the mechanism housing 601, the second belt 904 will drive the first pulley 604 to rotate. After the first pulley 604 rotates, it will drive the drive shaft 605 to rotate at high speed. When the drive shaft 605 rotates at high speed, it will drive the blades 603 to rotate at high speed in the mechanism housing 601, thereby breaking up the soil into mud. The mud will eventually be discharged through the discharge port 606, and the filter plate 607 can filter the mud when the mud is discharged.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
