A plurality of trenching teeth 9 are installed on the side of the track shoe 8 away from the frame 3. A fertilizer lifting plate 10 is fixedly installed in the middle of the track shoe 8 close to the frame 3. The frame 3 and the driving wheels 5 and the driven wheels 6 at both ends are provided with fertilizer paths 11 for the fertilizer lifting plates 10 to be embedded. A fertilizer hole 12 is also provided through the middle of the track shoe 8. A material discharge flap 13 turned outward toward the side of the trenching teeth 9 is also installed in the fertilization hole 12. The material discharge flap 13 is rotatably installed on the rotating shaft rod 26. A reset torsion spring is also sleeved in the rotating shaft rod 26. The reset torsion spring is used to keep the material discharge flap 13 in a blocked state for the fertilizer hole 12 without external force. During the reciprocating rotational motion, the trenching crawler 7 drives several track shoes 8 to reciprocate around the surface of the frame 3. The reciprocating motion of the track shoes 8 pushes the trenching teeth 9 and the fertilizer lifting plate 10 connected thereto to move synchronously. The trenching motion is performed through the contact between the trenching teeth 9 and the soil surface. A feeding mechanism is also provided in the fertilizer path 11 on the side of the driving wheel 5. The feeding mechanism delivers fertilizer into the fertilizer path 11, and the fertilizer is pushed into the fertilizer path 11 on the side of the driven wheel 6 through the movement of the fertilizer lifting plate 10. The feeding flap 13 is unfolded after reaching the side of the driven wheel 6 to release the fertilizer stored inside to the soil surface after trenching.

[0020] In this embodiment, the traction agricultural machine adopts a tractor head type traction structure commonly used in the prior art. Since its structure is common in the prior art, and the present embodiment also adopts a mature technical solution in the prior art, the traction agricultural machine will not be described in detail. The traction agricultural machine is connected to the towing head 1 by a pin shaft, so as to facilitate disassembly and assembly. The traction agricultural machine provides trenching and fertilizing power for the towing head 1, wherein the towing head 1 includes a traction protection frame 2 and a frame 3, and the traction protection frame 2 and the frame 3 are fixedly connected. A traction head 14 is also fixedly installed at one end of the guide and protection frame 2, and the traction head 14 makes the towing head 1 connected to the traction agricultural machine in a pin-axis manner. A driving wheel 5 and a driven wheel 6 are installed on both sides of the frame 3, wherein the driving wheel 5 and the driven wheel 6 are provided with track teeth that cooperate with the trenching crawler 7, and the trenching crawler 7 is driven to reciprocate and rotate by the rotation of the driving wheel 5 and the driven wheel 6. Different from the prior art, the trenching crawler 7 is composed of a plurality of track shoes 8 connected end to end, and a fertilizer is fixedly installed in the middle of the track shoe 8 close to the frame 3. The lifting plate 10, the frame 3, the driving wheel 5 at both ends and the driven wheel 6 are all provided with fertilizer paths 11 for the fertilizer lifting plate 10 to be embedded. A fertilizer hole 12 is also provided through the middle of the track shoe 8. A material unloading flap 13 is installed in the fertilization hole 12 in a rotating shaft manner. The material unloading flap 13 keeps the fertilization hole 12 blocked without external force, so that the fertilizer placed inside can be blocked to prevent it from leaking out. The fertilizer lifting plate 10 arranged on the track shoe 8 is located in the fertilizer path 11, and the fertilizer is pushed by the movement of the fertilizer lifting plate 10. It moves toward the fertilizing path 11 on one side of the driven wheel 6, and the unloading flap 13 expands outward after reaching the fertilizing path 11 on one side of the driven wheel 6. At this time, the fertilizing hole 12 is opened, so that the internal fertilizer can flow out through the fertilizing hole 12 and be spread on the soil where the trenching is completed. The advantage of this arrangement is that the trenching crawler 7 is no longer just used as a trenching device, it is also used as a part of the fertilizing mechanism, and the trenching and fertilizing operations are carried out simultaneously, and the degree of correlation between the structures is high, which improves the degree of integration of the device.

[0021] Embodiment 2: A cavity 15 is formed inside the driving wheel 5 and the driven wheel 6 , and through grooves 16 communicating with the cavity 15 are formed in an annular array on the surfaces of the driving wheel 5 and the driven wheel 6 .

[0022] The unloading mechanism includes an unloading inclined plate 17 and an unloading chute plate 18. The unloading chute plate 18 is arranged in the cavity 15 opened by the driving wheel 5. The unloading chute plate 18 is fixedly connected to the unloading inclined plate 17. The unloading inclined plate 17 is fixedly installed on the traction protection frame 2 at one end away from the unloading chute plate 18. A feeding box for feeding the unloading inclined plate 17 is arranged on one side of the traction protection frame 2. The fertilizer slides into the unloading gap 19 opened in the unloading chute plate 18 through the unloading inclined plate 17, flows out through the through groove 16 opened in the driving wheel 5 and falls into the inner side of the track shoe 8, and is pushed to move to the fertilization path 11 on the side of the driven wheel 6 as the track shoe 8 moves.

[0023] An air jet plate 20 is provided in the cavity 15 of the driven wheel 6. The air jet plate 20 is fixedly connected to the frame 3 through a fixed shaft 21. The air jet plate 20 does not move with the rotation of the driven wheel 6. An air jet hole 22 is provided on the air jet plate 20. The air jet hole 22 is movably matched with a material discharge flap 13 installed on the track shoe 8. When the material discharge flap 13 rotates to match with the air jet hole 22, the gas ejected through the air jet hole 22 passes through the through groove 16 provided in the driven wheel 6 and pushes the material discharge flap 13 to overcome the elastic force of the reset torsion spring to do work. At this time, the material discharge flap 13 is unfolded, and the gas simultaneously pushes the fertilizer stored inside to be released outward through the fertilization hole 12.

[0024] In this embodiment, a cavity 15 is provided in both the driving wheel 5 and the driven wheel 6, wherein a material discharge chute plate 18 is installed in the cavity 15 of the driving wheel 5, and the material discharge chute plate 18 is fixedly connected to the material discharge inclined plate 17, and the material discharge inclined plate 17 is fixedly installed on the traction protection frame 2 away from the end of the material discharge chute plate 18, so the material discharge chute plate 18 and the material discharge inclined plate 17 do not rotate with the rotation of the driving wheel 5, refer to the attached manual Figure 2As well as 4-6, when fertilizer is spread on the feeding inclined plate 17, due to the certain slope of the feeding inclined plate 17, the fertilizer falls down along the slope direction of the feeding inclined plate 17 under the action of gravity, and since the feeding inclined plate 17 is fixedly connected to the feeding trough plate 18, the material finally falls into the feeding slot 19 provided in the feeding trough plate 18 arranged in the cavity, and the feeding slot 19 is arranged downward, so the fertilizer passes through the feeding slot 19 and the through slot 16 provided in the driving wheel 5 to enter the inner side of the track shoe 8, and is separated by the fertilizer lifting plate 10 installed on the inner side of the track shoe 8. The fertilizer lifting plate 10 can be further installed with a leak-proof sealing plate on the side away from the track shoe 8, so as to ensure that the fertilizer lifting plate 10 does not leak during the process of pushing the fertilizer for transportation, and the material enters the inner side of the track shoe 8 along the rear edge It moves upward in the direction of the driving wheel 5 and moves toward the side of the driven wheel 6 through the fertilization path 11 opened on the frame 3, wherein a jet plate 20 is installed in the cavity 15 of the driven wheel 6, and the jet plate 20 is fixedly installed on the frame 3 through a fixed shaft 21, so that the jet plate 20 does not rotate with the rotation of the driven wheel 6, and an air jet hole 22 is opened on the jet plate 20, and the air jet hole 22 is movably matched with the unloading flap 13 installed on the track shoe 8. When the unloading flap 13 rotates to match with the air jet hole 22, the gas ejected through the air jet hole 22 passes through the through groove 16 opened in the driven wheel 6 and pushes the unloading flap 13 to overcome the elastic force of the reset torsion spring to do work. At this time, the unloading flap 13 is unfolded, and the gas simultaneously pushes the fertilizer stored inside to be released outward through the fertilization hole 12.

[0025] Embodiment three: An air jet pipe is provided on one side of the frame 3, and the air jet pipe is connected to the air jet hole 22 through the air passage opened on the fixed shaft 21 and the air jet plate 20. The end of the air jet pipe away from the air jet hole 22 is connected to the air pump installed in the frame 3, and the air pump works to pump air outward through the air jet hole 22.

[0026] In this embodiment, the air pump is fixedly arranged inside the frame 3, and the air pump is finally connected to the air jet hole 22 through the air jet pipe via the fixed shaft 21 and the air channel opened on the air jet plate 20, so that the gas generated by the air pump can be pumped out through the air jet hole 22. The gas pumped out of the air jet hole 22 provides turning power for the unloading flap 13 on the one hand, and provides power for the internal fertilizer to be spread outward on the other hand, so that the fertilizer passes through the fertilization hole 12 and falls into the opened groove.

[0027] Embodiment 4: The driving wheel 5 is also fixedly connected to the driven sprocket 23, and the driven sprocket 23 is connected to the driving sprocket installed on the traction agricultural machinery through a chain. The rotation of the driving sprocket provides power for the rotation of the driving wheel 5, and the feed box for storing fertilizer is fixedly installed on the traction agricultural machinery.

[0028] In this embodiment, the driving sprocket on the traction agricultural machine is rotated to provide power for the rotation of the driving wheel 5, thereby achieving the ditching and fertilizing operations.

[0029] Embodiment five: The driving wheel 5 is also fixedly connected to a spiral tillage rod 24, which is used to transport the soil dug out by trenching to the side.

[0030] A baffle 25 is also fixedly mounted on the frame 3 on one side of the spiral tiller rod 24 .

[0031] In this embodiment, the driving wheel 5 is also fixedly connected to the spiral tiller rod 24, and the driving wheel 5 rotates together with the spiral tiller rod 24. Since the trenching track 7 pushes the soil formed by the trenching upward during the reciprocating rotation, when the soil reaches one side of the spiral tiller rod 24, the rotation of the spiral tiller rod 24 causes the soil to be transported to one side of the opened trench, thereby ensuring the normal progress of the subsequent trenching operation.

[0032] Embodiment six: A blocking rod 27 is also fixedly mounted on the track shoe 8 in the fertilization hole 12 , and the blocking rod 27 is used to prevent the unloading flap 13 from flipping toward the side close to the frame 3 .

[0033] In this embodiment, the blocking rod 27 is used to prevent the material discharge flap 13 from flipping toward the side close to the frame 3. The significance of this structural setting is that the material discharge flap 13 can only be unfolded outward but not inward. This setting can effectively prevent the material discharge flap 13 from expanding inward due to the squeezing of the soil during the trenching process, thereby preventing the soil from entering the inner side of the track shoe 8, thereby ensuring the normal progress of the fertilization process.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
