[0002] A root-cutting mixer is needed for no-till reseeding operations in degraded grasslands. The existing root-cutting mixer is provided with running wheels on the left and right sides of the fuselage. During operation, the running wheels are driven by a tractor to move along the sowing row to carry out sowing operations. Before sowing, during medium and short-distance transportation, the root-cutting mixer is too wide to be driven on the road. The root-cutting mixer needs to be placed in the bucket of a transport vehicle and transported to the field, which is a relatively inconvenient process. Furthermore, the existing forage mixing usually mixes different types of forage seeds and fertilizers first, and then puts them into the seed box of the root-cutting mixer for sowing. Because the field ground is not flat enough, during the sowing process, the equipment is constantly bumped, causing high-density and large-mass seeds to sink continuously, and eventually the different types of forage seeds and fertilizers mixed before sowing become uneven due to the impact of bumps, affecting the sowing effect.

[0028] The utility model is described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 , Figure 6 As shown, a grass root cutting and mixing machine with automatic seed and fertilizer mixing function includes a frame 100, an operation moving mechanism 200, a transport moving mechanism 300, a seed box 400, an electric drive mechanism 500 and a seeding operation mechanism 700, wherein the operation moving mechanism 200 is arranged on the left and right sides of the frame 100, the transport moving mechanism 300 is arranged on the front and rear sides of the frame 100, the seed box 400 is arranged above the frame 100, and the seeding operation mechanism 700 is arranged below the frame 100;

[0030] The electric drive mechanism 500 includes a second mounting bracket 501 disposed on the frame 100 and a motor 502 disposed on the second mounting bracket 501. The seed box 400 is provided with a rotating shaft 503, and the rotating shaft 503 is connected to a spiral stirring blade 504 in the seed box 400 through a connecting rod 505. The power output end of the motor 502 is connected to the rotating shaft 503.

[0031] It also includes a gear ratchet transmission mechanism 600 connected between the operation moving mechanism 200 and the rotating shaft 503 for driving the rotating shaft 503 to rotate during the operation movement process.

[0032] During medium and short-distance transportation, the transport and mobile mechanism 300 is installed on the front and rear sides of the frame 100; after arriving at the cultivation site, before sowing operations, the transport and mobile mechanism 300 is disassembled. Different types of forage seeds and fertilizers are placed in the seed box 400, and the motor drives the rotating shaft 503 to rotate, so that the spiral stirring blades 504 mix the forage seeds and fertilizers before sowing. During sowing operations, the utility model is towed by a tractor, and the operation mobile mechanism 200 moves forward while sowing operations are performed. At the same time, the gear ratchet transmission mechanism 600 drives the rotating shaft 503 to rotate in the opposite direction during the operation movement, so that the spiral stirring blades 504 continuously mix the seeds, ensuring that the types of forage seeds and fertilizers are always in a mixed state, and avoiding the accumulation and blockage of large-particle, high-density, and high-mass seeds.

[0033] like Figure 2 , Figure 4 As shown, the working moving mechanism 200 includes a working traction connecting member 201 fixedly connected to the front end of the frame 100, two left and right first mounting brackets 202 fixedly arranged at the lower ends of the left and right sides of the frame 100, and two left and right first walking wheels 204 respectively connected to the left and right first mounting brackets 202 through two left and right connecting shafts 203.

[0034] When working, the working traction connecting member 201 is connected to the tractor, and under the traction of the tractor, the first traveling wheel 204 drives the whole machine to move forward.

[0035] like Figure 3 , Figure 5 As shown, the gear ratchet transmission mechanism 600 includes a gear 601 fixedly mounted on the connecting shaft 203, a ratchet gear 604 and a chain 602 arranged on the rotating shaft 503, the connecting shaft 203 is rotatably connected to the first mounting bracket 202, the first walking wheel 204 is fixedly connected to the connecting shaft 203, the ratchet gear 604 is located on the outside of the seed box 400, the ratchet gear 604 is a circular ring structure, the outer circumference of the ratchet gear 604 is provided with an outer gear ring, the chain 602 is connected between the outer gear ring of the ratchet gear 604 and the gear 601, the inner circumference of the ratchet gear 604 is provided with a circle of inner ratchet teeth, the rotating shaft 503 is connected with a pawl in the ratchet gear 604 corresponding to the inner ratchet teeth, and the driving rotation direction of the motor 502 is opposite to the rotation direction of the rotating shaft 503 during the operation and movement.

[0036] The frame 100 is provided with a notch 603 , and the chain 602 passes through the notch 603 .

[0037] The ratchet gear 604 is meshed with the pawl, the pawl is arranged on a spindle, and a retaining spring is arranged between the pawl and the spindle. During sowing operation, the first walking wheel 204 drives the connecting shaft 203 to rotate, thereby driving the ratchet gear 604 to rotate in the opposite direction through the gear 601 and the chain 602. At this time, the inner ratchet of the ratchet gear 604 is meshed with the pawl, and the inner ratchet drives the rotating shaft 503 to rotate in the opposite direction through the pawl, so that the spiral stirring blade 504 continuously mixes the seeds. Since the driving rotation direction of the motor 502 is opposite to the rotation direction of the rotating shaft 503 during the operation and movement, when the motor 502 drives the rotating shaft 503 to rotate forward, the pawl slides over the inner ratchet and cannot drive the ratchet gear 604 to rotate. The specific matching mode of the ratchet gear 604 and the pawl refers to the internal meshing tooth ratchet mechanism, which is a prior art and will not be described in detail here.

[0038] like Figure 2-4 As shown, the transport movement mechanism 300 includes a connecting frame 301 fixedly arranged at the left end of the frame 100, a transport traction connecting piece 302 fixedly connected to the connecting frame 301, front and rear connecting plates 303 fixedly arranged at the lower ends of the front and rear sides of the frame 100, front and rear connecting columns 306 respectively located on the sides of the front and rear connecting plates 303, and front and rear second walking wheels 307 connected to the front and rear connecting columns 306 through front and rear wheel axles, the connecting plate 303 is connected to more than two U-shaped screws 304, the connecting column 306 is located between the corresponding connecting plate 303 and the U-shaped screw 304, and the U-shaped screw 304 is connected to the locking nut 305 to lock the connecting column 306.

[0039] When medium or short-distance transportation is required, the connecting column 306 is connected to the connecting plate 303 by the U-shaped screw 304 and the locking nut 305, so that the second running wheel 307 is installed on the front and rear sides of the frame 100. The installation height of the connecting column 306 needs to meet the requirement that when the second running wheel 307 is in contact with the ground, the first running wheel 204 leaves the ground. It is connected to the tractor through the transport traction connector 302, and under the traction of the tractor, the whole machine is driven to move to the farming site by the second running wheel 307. After arriving at the farming site, loosen the locking nut 305, remove the connecting column 306 and the second running wheel 307, and it will not affect the subsequent farming operations. The walking direction of the transport mobile mechanism 300 is perpendicular to the walking direction of the operating mobile mechanism 200, and the two do not affect each other.

[0040] like Figure 1 , Figure 2 , Figure 6As shown, the seed box 400 includes a U-shaped storage box 402 and a box cover 404 located at the top opening of the U-shaped storage box 402. The box cover 404 is connected to the top of one side of the U-shaped storage box 402 through a hinge. Two left and right vertical plates 401 are fixedly provided at the upper ends of the left and right sides of the frame 100. The U-shaped storage box 402 is located between the two vertical plates 401. A support frame 403 is provided between the U-shaped storage box 402 and the frame 100. Before sowing, open the box cover 404 and put the forage seeds and fertilizers into the U-shaped storage box 402.

[0041] like Figure 7 As shown, the seeding mechanism 700 includes a mounting frame 706 fixedly connected to the lower end of the frame 100, and a root cutting plate 701, a furrowing sowing assembly and a pressing wheel 703 sequentially installed at the lower end of the mounting frame 706 from front to back, and the root cutting plate 701, the furrowing sowing assembly and the pressing wheel 703 are opposite to each other front to back.

[0042] The furrowing and sowing assembly includes two left and right furrowing plates 705, which are inclined inward from top to bottom. The lower end of the mounting frame 706 is connected to a horizontal axis through a vertical rod. The two furrowing plates 705 are rotatably mounted on the left and right ends of the axis. A row of outlets are provided at the bottom of the seed box 400, and a seed dropper 702 is provided at the lower end of each outlet. A hose 704 is connected to the lower port of the seed dropper 702. The mounting frame 706 is provided with a seed dropper port in the middle above the left and right furrowing plates 705, and the hose 704 is connected to the seed dropper port.

[0043] The seeding device 702 at the lower end of the seed box 400 is an existing structure. A seeding impeller is arranged in the housing of the seeding device 702. A rotating shaft driven by a driving motor passes through the housing, and the seeding impeller is installed on the rotating shaft. When working, the driving motor drives the rotating shaft to rotate, thereby driving the seeding impeller to rotate, and continuously sending the seeds and fertilizers above the seeding impeller to the bottom of the seeding impeller, and outputting them to the hose 704 from the lower port.

[0044] The root cutting disc 701 is 3 mm thick and is rotatably mounted on the root cutting disc shaft. During sowing operations, the lower half of the root cutting disc 701 cuts into the ground. During the forward movement of the utility model, the entire machine drives the root cutting disc 701 to move forward and rotate continuously, cutting a thin crack in the ground and cutting the plant roots in the ground. Two furrowing discs 705 are located behind the root cutting disc 701. The entire machine drives the two furrowing discs 705 to move forward and rotate continuously, expanding the thin crack in the ground to both sides to form a fine groove. At the same time, forage seeds and fertilizers fall from the seeding port between the two furrowing discs 705 and enter the fine groove. The pressure wheel 703 is located directly behind the furrowing sowing component, pressing over the fine groove, pressing the soil beside the fine groove into the fine groove, and making the seeds and fertilizers fully contact with the soil to prevent the seeds from being blown away by strong winds.

[0045] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
