Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and particularly to a ditching and fertilizing integrated machine for forest land. Background Technique

[0002] In the prior art, a ditching and fertilizing integrated machine with the publication number of "CN105532127B" includes a frame that can be connected to a power locomotive. A gearbox that is power-connected to a power mechanism is hinge-mounted on the frame. A lifting power mechanism for driving the gearbox to swing is installed on the frame. A horizontally arranged power output shaft is installed at the bottom of the gearbox. Two oppositely arranged ditching mounting seats are power-connected to the power output shaft. Multiple ditching knives are installed on the ditching mounting seats along their circumferences. The rotation trajectories of the multiple ditching knives on the same ditching mounting seat form a ditching surface. The bottoms of the two ditching surfaces are close to each other and the tops are open. A fertilizer box is connected to the frame. The ditching and fertilizing integrated machine further includes a ditching soil retaining plate frame and a soil covering soil retaining plate frame that are alternatively connected to the gearbox during use. A fertilizer pipe is connected to the soil covering soil retaining plate frame. This device can achieve two operations of ditching and ditching with fertilizing, and has the advantages of a large ditching width, a large depth, and a good effect of ditching, fertilizing, and soil covering.

[0003] However, the above device still has relatively obvious defects during use: the above device is respectively provided with a ditching mechanism and a fertilizing mechanism, and the two complete independent functions respectively, so that the structural setting of the above device is not compact enough to meet the requirements of compactness and integration of agricultural machinery equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a ditching and fertilizing integrated machine for forest land to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A ditching and fertilizing integrated machine for forest land includes a towing agricultural machine and a towed head. The towing agricultural machine and the towed head are connected by a pin shaft. The towing agricultural machine provides power for ditching and fertilizing for the towed head.

[0007] The towed head includes a towing protection frame and a frame. The towing protection frame and the frame are fixedly connected. Track wheel grooves are opened at both the front and rear ends in the moving direction of the frame. A driving wheel is rotatably installed on a fixed axis through a rotating shaft in the track wheel groove close to the towing protection frame side, and a driven wheel is rotatably installed on a fixed axis in the track wheel groove on the other side. An opening track is installed on the driving wheel and the driven wheel. The synchronous rotation of the driving wheel and the driven wheel drives the opening track to perform a reciprocating rotational motion.

[0008] The ditch-opening crawler belt is composed of a number of crawler plates connected end to end. A number of ditch-opening teeth are installed on the side of the crawler plate away from the machine frame. A fertilizer-lifting plate is fixedly installed in the middle of the side of the crawler plate close to the machine frame. Fertilizer channels for the fertilizer-lifting plate to be inserted into are correspondingly provided on the machine frame, the driving wheels at both ends and the driven wheels. A fertilizer hole is also penetratingly provided in the middle of the crawler plate. A blanking flap that turns outwards towards the ditch-opening teeth is also installed in the fertilizer hole. The blanking flap is rotatably installed on a rotating shaft rod. A reset torsion spring is also sleeved in the rotating shaft rod. The reset torsion spring is used to keep the blanking flap in a state of blocking the fertilizer hole without external force.

[0009] During the reciprocating rotational movement of the ditch-opening crawler belt, a number of crawler plates are driven to perform reciprocating movement around the surface of the machine frame. The reciprocating movement of the crawler plates drives the connected ditch-opening teeth and fertilizer-lifting plates to move synchronously. Ditch-opening movement is carried out through the contact between the ditch-opening teeth and the soil surface. A blanking mechanism is also provided in the fertilizer channel on one side of the driving wheel. The blanking mechanism feeds fertilizer into the fertilizer channel. The fertilizer is pushed to the fertilizer channel on the side of the driven wheel through the movement of the fertilizer-lifting plate. After the blanking flap reaches the side of the driven wheel, it unfolds to release the stored fertilizer onto the surface of the soil after ditch-opening.

[0010] Preferably, a towing head is also fixedly installed on the towing protection frame. The towing head is pin-connected with a towing agricultural machine through a pin shaft.

[0011] Preferably, cavities are provided in both the driving wheel and the driven wheel. Through grooves communicating with the cavities are annularly and arrayedly provided on the surfaces of the driving wheel and the driven wheel.

[0012] Preferably, the blanking mechanism includes a blanking inclined plate and a blanking groove plate. The blanking groove plate is arranged in the cavity provided in the driving wheel. The blanking groove plate is fixedly connected with the blanking inclined plate. One end of the blanking inclined plate away from the blanking groove plate is fixedly installed on the towing protection frame. A feeding box for feeding the blanking inclined plate is provided on one side of the towing protection frame. Fertilizer slides into the blanking seam provided in the blanking groove plate through the blanking inclined plate, flows out through the through groove provided in the driving wheel and falls into the inner side of the crawler plate, and the fertilizer is pushed towards the fertilizer channel on the side of the driven wheel along with the movement of the crawler plate.

[0013] Preferably, an air jet plate is provided in the cavity of the driven wheel. The air jet plate is fixedly connected with the machine frame through a fixed shaft. The air jet plate does not move with the rotation of the driven wheel. Air jet holes are provided on the air jet plate. The air jet holes are movably matched with the blanking flap installed on the crawler plate. When the blanking flap rotates to cooperate with the air jet holes, the gas sprayed through the air jet holes passes through the through groove provided in the driven wheel and pushes the blanking flap to do work against the elastic force of the reset torsion spring. At this time, the blanking flap unfolds, and the gas also pushes the stored fertilizer inside to be released out through the fertilizer hole.

[0014] Preferably, an air jet pipe is provided on one side of the frame. The air jet pipe is communicated with the air jet holes through a fixed shaft and an air duct formed in the air jet plate. One end of the air jet pipe away from the air jet holes is communicated with an air pump installed in the frame, and the air pump operates to pump air out through the air jet holes.

[0015] Preferably, the driving wheel is also fixedly connected to a driven sprocket. The driven sprocket is connected to a driving sprocket installed on a traction agricultural machine through a chain. The rotation of the driving sprocket provides power for the rotation of the driving wheel. A feeding box for storing fertilizers is fixedly installed on the traction agricultural machine.

[0016] Preferably, the driving wheel is also fixedly connected to a spiral soil turning rod, and the spiral soil turning rod is used to convey the soil dug out by the trench digging to the side.

[0017] Preferably, a baffle is fixedly installed on the frame on one side of the spiral soil turning rod.

[0018] Preferably, a blocking rod is fixedly installed on the crawler plate in the fertilizer application hole, and the blocking rod is used to block the turning of the blanking flap towards the side close to the frame.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] The trench digging crawler of the present invention not only serves as a trench digging mechanism but also as a pushing mechanism for fertilizer conveyance. Fertilizer application holes for fertilizer release are formed in the crawler plate. By integrating the trench digging mechanism and the fertilizer application mechanism, the structure design is more compact and the integration degree of the device is higher.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-8 , the present invention provides a technical solution:

[0032] Embodiment 1:

[0033] A ditching and fertilizing machine for forest land includes a traction agricultural machine and a drag-type nose 1. The traction agricultural machine and the drag-type nose 1 are connected by a pin shaft. The traction agricultural machine provides ditching and fertilizing power for the drag-type nose 1;

[0034] The drag-type nose 1 includes a traction protection frame 2 and a frame 3. The traction protection frame 2 and the frame 3 are fixedly connected. Crawler wheel grooves 4 are provided at both the front and rear ends of the moving direction of the frame 3. A driving wheel 5 is rotatably installed in the crawler wheel groove 4 near the traction protection frame 2 by a rotating shaft, and a driven wheel 6 is rotatably installed in the crawler wheel groove 4 on the other side. A ditching crawler 7 is installed on the driving wheel 5 and the driven wheel 6. The synchronous rotation of the driving wheel 5 and the driven wheel 6 drives the ditching crawler 7 to perform a reciprocating rotational motion;

[0035] The trenching crawler 7 is composed of a number of crawler plates 8 connected end to end. A number of trenching teeth 9 are installed on one side of the crawler plate 8 away from the frame 3. A fertilizing flap 10 is fixedly installed in the middle of the side of the crawler plate 8 close to the frame 3. Fertilizing channels 11 for the fertilizing flap 10 to be inserted into are correspondingly provided on the frame 3, the driving wheels 5 at both ends and the driven wheels 6. A fertilizing hole 12 is also penetrated through the middle of the crawler plate 8. A discharging flap 13 that turns outwards towards the trenching teeth 9 is installed in the fertilizing hole 12. The discharging flap 13 is rotatably installed on a 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 discharging flap 13 in a state of blocking the fertilizing hole 12 under the condition of no external force.

[0036] During the reciprocating rotation movement of the trenching crawler 7, a number of crawler plates 8 are driven to move reciprocally around the surface of the frame 3. The reciprocating movement of the crawler plates 8 pushes the connected trenching teeth 9 and fertilizing flap 10 to move synchronously. Trenching movement is carried out through the contact between the trenching teeth 9 and the soil surface. A feeding mechanism is also arranged in the fertilizing channel 11 on one side of the driving wheel 5. The feeding mechanism feeds fertilizers into the fertilizing channel 11. The fertilizers are pushed into the fertilizing channel 11 on the side of the driven wheel 6 through the movement of the fertilizing flap 10. After the discharging flap 13 reaches the side of the driven wheel 6, it unfolds to release the stored fertilizers onto the trenched soil surface.

[0037] In this embodiment, the traction agricultural machine adopts the common tractor - head - type traction structure in the prior art. Since this structure is common in the prior art and the same mature technical solutions in the prior art are also adopted in this embodiment, the traction agricultural machine will not be elaborated here. The traction agricultural machine is connected to the trailing - type head 1 by a pin shaft, which facilitates disassembly and assembly. The traction agricultural machine provides power for ditching and fertilizing for the trailing - type head 1. The trailing - type head 1 includes a traction protective frame 2 and a frame 3. The traction protective frame 2 and the frame 3 are fixedly connected. One end of the traction protective frame 2 is also fixedly installed with a traction head 14. Through the traction head 14, the trailing - type head 1 is connected to the traction agricultural machine in a pin - shaft manner. Driving wheels 5 and driven wheels 6 are installed on both sides of the frame 3. Traction teeth matching with the ditching crawler 7 are provided on the driving wheels 5 and the driven wheels 6. The rotation of the driving wheels 5 and the driven wheels 6 drives the ditching crawler 7 to perform a reciprocating rotational motion. Different from the prior art, the ditching crawler 7 is composed of a number of crawler plates 8 connected end - to - end. A fertilizing flap 10 is fixedly installed in the middle of the side of the crawler plate 8 close to the frame 3. Fertilizing channels 11 for the fertilizing flap 10 to be inserted into are correspondingly opened on the frame 3, the driving wheels 5 at both ends and the driven wheels 6. A fertilizing hole 12 is also penetratingly opened in the middle of the crawler plate 8. A blanking flap 13 is rotatably installed in the fertilizing hole 12. The blanking flap 13 keeps blocking the fertilizing hole 12 without external force, so as to prevent the fertilizer placed inside from leaking out. The fertilizing flap 10 provided on the crawler plate 8 is located in the fertilizing channel 11. The movement of the fertilizing flap 10 makes it push the fertilizer towards the fertilizing channel 11 on the side of the driven wheel 6. The blanking flap 13 unfolds outward after reaching the fertilizing channel 11 on the 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 sown on the soil after ditching. The advantage of this setting is that the ditching crawler 7 is no longer only used as a ditching device, but also serves as a part of the fertilizing mechanism, enabling the ditching and fertilizing operations to be synchronized, and the degree of association between the structures is high, improving the integration degree of the device.

[0038] Embodiment Two:

[0039] Cavities 15 are opened inside both the driving wheel 5 and the driven wheel 6. Through - grooves 16 communicating with the cavities 15 are annularly and array - type opened on the surfaces of the driving wheel 5 and the driven wheel 6.

[0040] The blanking mechanism includes a blanking inclined plate 17 and a blanking chute plate 18. The blanking chute plate 18 is arranged in a cavity 15 opened in the driving wheel 5. The blanking chute plate 18 is fixedly connected to the blanking inclined plate 17. One end of the blanking inclined plate 17 away from the blanking chute plate 18 is fixedly installed on the traction protection frame 2. A feeding box for feeding the blanking inclined plate 17 is arranged on one side of the traction protection frame 2. Fertilizer slides into a blanking slit 19 opened in the blanking chute plate 18 through the blanking inclined plate 17, and flows out through a through groove 16 opened in the driving wheel 5 and falls into the inner side of the crawler plate 8, and the fertilizer is pushed towards the fertilizing channel 11 on the side of the driven wheel 6 along with the movement of the crawler plate 8.

[0041] A jet plate 20 is arranged in a cavity 15 of the driven wheel 6. The jet plate 20 is fixedly connected to the machine frame 3 through a fixed shaft 21. The jet plate 20 does not move with the rotation of the driven wheel 6. Jet holes 22 are opened in the jet plate 20. The jet holes 22 are movably matched with a blanking flap 13 installed on the crawler plate 8. When the blanking flap 13 rotates to be matched with the jet holes 22, the gas ejected through the jet holes 22 passes through a through groove 16 opened in the driven wheel 6 and pushes the blanking flap 13 to do work against the elastic force of the return torsion spring. At this time, the blanking flap 13 unfolds, and the gas simultaneously pushes the stored fertilizer inside to be released outward through a fertilizing hole 12.

[0042] In this embodiment, cavities 15 are opened in both the driving wheel 5 and the driven wheel 6. Among them, a blanking chute plate 18 is installed in the cavity 15 of the driving wheel 5. The blanking chute plate 18 is fixedly connected to the blanking inclined plate 17. One end of the blanking inclined plate 17 away from the blanking chute plate 18 is fixedly installed on the traction protection frame 2. Therefore, the blanking chute plate 18 and the blanking inclined plate 17 do not rotate with the rotation of the driving wheel 5. Refer to the attached Figure 2As shown in FIGS. 4 - 6, when the fertilizer is spread onto the inclined feeding plate 17, due to the certain slope of the inclined feeding plate 17, the fertilizer falls along the slope direction of the inclined feeding plate 17 under the action of gravity. Since the inclined feeding plate 17 is fixedly connected to the feeding chute plate 18, the material finally falls into the blanking slit 19 opened in the feeding chute plate 18 provided in the cavity. The blanking slit 19 is arranged downward, so the fertilizer passes through the blanking slit 19 and passes through the through - groove 16 opened in the driving wheel 5 into the inner side of the crawler plate 8, and is spaced by the fertilizer - spreading flap 10 installed on the inner side of the crawler plate 8. A leak - proof sealing plate can be further installed on the side of the fertilizer - spreading flap 10 away from the crawler plate 8, so as to ensure that no leakage occurs during the process of the fertilizer - spreading flap 10 pushing the fertilizer for transfer. After the material enters the inner side of the crawler plate 8, it moves upward along the direction of the driving wheel 5 and moves towards the driven wheel 6 through the fertilizing channel 11 opened on the frame 3. A jet plate 20 is installed in the cavity 15 of the driven wheel 6. 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 along with the rotation of the driven wheel 6. The jet plate 20 is provided with jet holes 22, and the jet holes 22 are movably matched with the blanking flap 13 installed on the crawler plate 8. When the blanking flap 13 rotates to be matched with the jet holes 22, the gas ejected through the jet holes 22 passes through the through - groove 16 opened in the driven wheel 6 and pushes the blanking flap 13 to do work against the elastic force of the return torsion spring. At this time, the blanking flap 13 unfolds, and the gas simultaneously pushes the fertilizer stored inside to be released outward through the fertilizing holes 12.

[0043] Embodiment Three:

[0044] A jet pipe is arranged on one side of the frame 3. The jet pipe is communicated with the jet holes 22 through the air duct opened on the fixed shaft 21 and the jet plate 20. One end of the jet pipe away from the jet holes 22 is communicated with an air pump installed inside the frame 3, and the air pump works to pump air outward through the jet holes 22.

[0045] In this embodiment, the air pump is fixedly arranged inside the frame 3. The air pump is finally communicated with the jet holes 22 through the jet pipe via the air duct opened on the fixed shaft 21 and the jet plate 20, so that the gas generated by the air pump can be pumped out through the jet holes 22. The gas pumped out through the jet holes 22 provides the turning power for the blanking flap 13 on the one hand and provides the power for the external spreading of the internal fertilizer on the other hand, so that the fertilizer passes through the fertilizing holes 12 and falls into the opened groove.

[0046] Embodiment Four:

[0047] The driving wheel 5 is also fixedly connected to a driven sprocket 23. The driven sprocket 23 is connected to the driving sprocket installed on the towing agricultural machine through a chain. The rotation of the driving sprocket provides power for the rotation of the driving wheel 5. The feeding box for storing fertilizer is fixedly installed on the towing agricultural machine.

[0048] In this embodiment, the rotation of the driving sprocket on the traction agricultural machine is used to provide power for the rotation of the driving wheel 5, thereby realizing the operations of ditching and fertilizing.

[0049] Embodiment Five:

[0050] The driving wheel 5 is also fixedly connected to the spiral soil-turning rod 24, and the spiral soil-turning rod 24 is used to convey the soil dug out by ditching to the side.

[0051] A baffle 25 is also fixedly installed on the frame 3 on one side of the spiral soil-turning rod 24.

[0052] In this embodiment, the driving wheel 5 is also fixedly connected to the spiral soil-turning rod 24, and the driving wheel 5 together with the spiral soil-turning rod 24 rotates. Since the ditching crawler 7 pushes the soil formed by ditching upward during the reciprocating rotation, when the soil reaches one side of the spiral soil-turning rod 24, the rotation of the spiral soil-turning rod 24 makes the soil conveyed to one side of the dug trench, thereby ensuring the normal progress of the subsequent ditching operation.

[0053] Embodiment Six:

[0054] A blocking rod 27 is also fixedly installed on the crawler plate 8 in the fertilizing hole 12, and the blocking rod 27 is used to block the blanking flap 13 from turning towards the side close to the frame 3.

[0055] In this embodiment, the blocking rod 27 is used to block the blanking flap 13 from turning towards the side close to the frame 3. The significance of this structural setting is that the blanking flap 13 can only be unfolded outward and cannot be unfolded inward. Such a setting can effectively prevent the blanking flap 13 from being unfolded inward due to the extrusion of soil during the ditching process, and further prevent soil from entering the inside of the crawler plate 8, thereby ensuring the normal progress of the fertilizing process.

[0056] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
