Description

Technical Field

[0001] The utility model relates to the technical field of accessories for tractor boats, in particular to a tractor boat hull with a mounting function. Background Art

[0002] A tractor boat is an agricultural machine used for tillage operations in special terrains such as paddy fields and lake fields. It can travel and perform tillage operations in muddy paddy fields, with flexible operation and convenient use, greatly improving the tillage efficiency. The existing tractor boats can achieve amphibious use by replacing wheels. When the tractor boat is working, generally, the land driving wheels first pass through the cement road from the warehouse to the side of the paddy field, and then the land driving wheels are replaced with paddy field driving wheels so that it can travel and perform tillage operations in the paddy field.

[0003] The paddy field driving wheels usually need to be transported to the side of the paddy field together with the whole vehicle. Due to the limited position of the tractor boat hull, the paddy field driving wheels cannot be carried along with the vehicle, and the transportation is very inconvenient. Usually, other vehicles are needed to transport them to the side of the paddy field together. The transportation steps are cumbersome and troublesome. Therefore, it is necessary to improve it. Summary of the Invention

[0004] The utility model provides a tractor boat hull with a mounting function to solve the problem that the existing tractor boats cannot carry the paddy field driving wheels along with the vehicle, resulting in troublesome transportation of the paddy field driving wheels.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A tractor boat hull with a mounting function includes a tractor boat body. An assembly concave is arranged at the front end of the tractor boat body, and a housing is installed on the assembly concave. The housing is a long rectangular body, and an assembly groove is opened on the housing. A rotating shaft is movably installed in the assembly groove, a gear is fixedly installed on the rotating shaft, racks are respectively movably installed in the assembly grooves at the upper and lower ends of the gear, the racks are respectively meshed with the gear, one end of each rack extends to the outside of the housing, and a mounting hook is installed on the rack extending to the outside of the housing.

[0006] The effects achieved by the above components are as follows: Through the mutual cooperation of the gear and the racks, the gear can drive the racks to extend out of the housing, and the racks drive the mounting hooks to extend out synchronously. Through the mutual cooperation of the racks and the mounting hooks, they can be used to mount the paddy field driving wheels, facilitating the carrying of the paddy field driving wheels along with the vehicle. The mounting hooks can also limit the paddy field driving wheels to prevent them from slipping off the racks during transportation.

[0007] Preferably, a cover plate is fixedly installed on the housing through bolts, and the cover plate is a rectangular plate.

[0008] The effects achieved by the above components are as follows: The housing and the cover plate can be fixedly connected by bolts. The cover plate can limit the rack and the gear inside the housing, which facilitates assembly and at the same time prevents the rack and the gear from slipping out of the housing.

[0009] Preferably, threaded holes are provided at the four corner positions of the housing, and fixing holes are provided on the cover plate corresponding to the threaded holes.

[0010] The effects achieved by the above components are as follows: The bolt passes through the fixing hole of the cover plate and is threadedly connected to the threaded hole of the housing, thereby realizing the detachable connection between the housing and the cover plate, which facilitates subsequent maintenance operations.

[0011] Preferably, a relief opening is provided on the cover plate at a position corresponding to the rotating shaft.

[0012] The effects achieved by the above components are as follows: Through the relief opening, it is convenient for the cover plate to make way for the rotating shaft so that the rotating shaft can perform a rotating operation.

[0013] Preferably, the hanging hook is a plate-shaped body with a "T"-shaped cross-section.

[0014] The effects achieved by the above components are as follows: The hanging hook can limit the central hole of the paddy field driving wheel, thereby preventing the paddy field driving wheel from slipping off the rack.

[0015] Preferably, the hanging hook has a "ㄦ"-shaped cross-section.

[0016] The effects achieved by the above components are as follows: By inwardly squeezing the hanging hook, the hanging hook can pass through the central hole of the paddy field driving wheel. When the hanging hook is released, the hanging hook deforms and self-restores, so that the hanging hook can limit the paddy field driving wheel, thereby realizing the hanging of the paddy field driving wheel.

[0017] Preferably, a handwheel is fixedly installed on the rotating shaft.

[0018] The effects achieved by the above components are as follows: The handwheel facilitates driving the rotating shaft to rotate, thereby realizing the rotating shaft driving the gear to rotate and the gear driving the rack to displace.

[0019] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0020] In the present utility model, the rotating shaft is driven to rotate by the handwheel, and the gear rotates synchronously with the rotating shaft. Thus, the rack is driven to displace in the same or opposite direction by the gear, so that the rack can extend to the outside of the housing to hang the paddy field driving wheel or be retracted into the housing. This tillage hull solves the problem that the existing tillage boat cannot carry the paddy field driving wheel with the vehicle, resulting in troublesome transportation of the paddy field driving wheel.

An assembly concave 2 is provided at the front end of the cultivator boat body 1. The purpose of such a setting is: to form a relief for the housing 3 to facilitate the installation of the housing 3.

[0028] Referring to Figure 2 - Figure 3 As shown, a housing 3 is fixedly installed on the assembly concave 2. The housing 3 is a long rectangular body. A cover plate 8 is fixedly installed on the housing 3 by bolts. The cover plate 8 is a rectangular plate. Threaded holes 9 are provided at the four corners of the housing 3. Fixed holes 10 are provided on the cover plate 8 corresponding to the threaded holes 9. During operation, the bolts pass through the fixed holes 10 of the cover plate 8, and the bolts are threadedly connected to the threaded holes 9 of the housing 3. The bolts can fixedly connect the housing 3 and the cover plate 8. The cover plate 8 can limit the rack 6 and the gear 5 in the housing 3, facilitating assembly and preventing the rack 6 and the gear 5 from disengaging from the housing 3. The detachable connection between the housing 3 and the cover plate 8 also facilitates subsequent maintenance operations.

[0029] Referring to Figure 3 As shown, an assembly groove 4 is provided on the housing 3. A rotating shaft 14 is movably installed in the assembly groove 4. A gear 5 is fixedly installed on the rotating shaft 14. Racks 6 are respectively movably installed in the assembly grooves 4 at the upper and lower ends of the gear 5. The racks 6 are respectively meshed with the gear 5. One end of the rack 6 extends to the outside of the housing 3. During operation, through the mutual cooperation of the gear 5 and the rack 6, the gear 5 can drive the rack 6 to extend out of the housing 3 synchronously.

[0030] Referring to Figure 3As shown, a hanging hook 7 is fixedly installed on the rack 6 extending to the outside of the housing 3. The hanging hook 7 is a plate-shaped body with a "T"-shaped cross-section. During operation, the rack 6 drives the hanging hook 7 to extend outward synchronously. The cooperation between the rack 6 and the hanging hook 7 can be used to hang the paddy field driving wheel 12, which is convenient for carrying the paddy field driving wheel 12 along with the vehicle. The center hole of the paddy field driving wheel 12 can be limited by the hanging hook 7 to prevent the paddy field driving wheel 12 from slipping off the rack 6 during transportation.

[0031] Referring to Figure 3 As shown, a relief opening 11 is provided on the cover plate 8 at a position corresponding to the rotating shaft 14. Through the relief opening 11, it is convenient for the cover plate 8 to form a relief for the rotating shaft 14 so that the rotating shaft 14 can perform a rotating operation.

[0032] Referring to Figure 2 - Figure 3 As shown, a handwheel 13 is fixedly installed on the rotating shaft 14. During operation, it is convenient to drive the rotating shaft 14 to rotate through the handwheel 13. Thus, the rotating shaft 14 can be driven to drive the gear 5 to rotate, and the gear 5 drives the rack 6 to displace.

[0033] Working principle: When it is necessary to hang the paddy field driving wheel 12 on the hull of the tiller boat, first rotate the handwheel 13 clockwise. The handwheel 13 drives the rotating shaft 14 and the gear 5 to rotate clockwise synchronously. While the gear 5 rotates clockwise, it drives the two racks 6 to perform relative movement synchronously. At this time, the racks 6 extend to the outside of the housing 3. While the racks 6 extend to the outside of the housing 3, they drive the hanging hooks 7 to move synchronously. Then, align the center hole of the paddy field driving wheel 12 with the hanging hook 7 so that the hanging hook 7 passes through the center hole of the paddy field driving wheel 12. Referring to Figure 5 As shown, then place the paddy field driving wheel 12 on the rack 6, thereby realizing the hanging of the paddy field driving wheel 12 on the rack 6. The hanging hook 7 can limit the paddy field driving wheel 12 to prevent the paddy field driving wheel 12 from slipping off the rack 6. Then the tiller boat can be started, and the paddy field driving wheel 12 can travel to the edge of the paddy field together with the vehicle.

[0034] When the tiller boat reaches the edge of the paddy field, remove the paddy field driving wheel 12 from the rack 6 and the hanging hook 7, and rotate the handwheel 13 counterclockwise to make the handwheel 13 drive the rack 6 and the hanging hook 7 to reset, thereby completing the entire operation of hanging the paddy field driving wheel 12.

[0035] Embodiment 2, referring to Figure 1 - Figure 2 As shown, this embodiment discloses a tiller boat hull with a hanging function, including a tiller boat body 1. An assembly concave 2 is provided at the front end of the tiller boat body 1. The purpose of such a setting is: to form a relief for the housing 3 to facilitate the installation of the housing 3.

[0036] Referring to Figure 2 - Figure 3As shown, a shell 3 is fixedly installed on the assembly recess 2. The shell 3 is a long rectangular body. A cover plate 8 is fixedly installed on the shell 3 by bolts. The cover plate 8 is a rectangular plate. Threaded holes 9 are provided at the four corners of the shell 3. Fixing holes 10 are provided on the cover plate 8 corresponding to the threaded holes 9. When working, the bolts pass through the fixing holes 10 of the cover plate 8 and are threadedly connected to the threaded holes 9 of the shell 3. The bolts can fix the shell 3 and the cover plate 8. The cover plate 8 can limit the rack 6 and the gear 5 in the shell 3, which facilitates assembly and prevents the rack 6 and the gear 5 from falling out of the shell 3. The detachable connection between the shell 3 and the cover plate 8 also facilitates subsequent maintenance operations.

[0037] Reference Figure 3 As shown, an assembly groove 4 is provided on the shell 3, and a rotating shaft 14 is movably installed in the assembly groove 4. A gear 5 is fixedly installed on the rotating shaft 14. Racks 6 are movably installed in the assembly grooves 4 at the upper and lower ends of the gear 5. The racks 6 are respectively engaged with the gears 5, and one end of the rack 6 extends to the outside of the shell 3. When working, the gear 5 and the rack 6 cooperate with each other, and the gear 5 can drive the rack 6 to extend synchronously to the outside of the shell 3.

[0038] Reference Figure 4 As shown, a mounting hook 7 is fixedly mounted on the rack 6 extending to the outside of the shell 3. The mounting hook 7 has an "ER"-shaped cross section. The mounting hook 7 is squeezed inward so that the mounting hook 7 passes through the center hole of the paddy field drive wheel 12. When the mounting hook 7 is released, the deformation of the mounting hook 7 is restored by itself, so that the mounting hook 7 can limit the paddy field drive wheel 12, thereby realizing the mounting of the paddy field drive wheel 12 and preventing the paddy field drive wheel 12 from slipping off the rack 6 during transportation.

[0039] Reference Figure 3 As shown, a clearance opening 11 is provided on the cover plate 8 at a position relative to the rotation shaft 14 . The clearance opening 11 facilitates the cover plate 8 to make way for the rotation shaft 14 so that the rotation shaft 14 can be rotated.

[0040] Reference Figure 2 - Figure 3 As shown, a hand wheel 13 is fixedly mounted on the rotating shaft 14. When working, the hand wheel 13 conveniently drives the rotating shaft 14 to rotate, thereby enabling the rotating shaft 14 to drive the gear 5 to rotate, and the gear 5 drives the rack 6 to move.

[0041] Working principle: When it is necessary to mount the paddy field drive wheel 12 on the hull of the tillage boat, first rotate the handwheel 13 clockwise. The handwheel 13 drives the rotating shaft 14 and the gear 5 to rotate clockwise synchronously. While the gear 5 rotates clockwise, it drives the two racks 6 to move relatively synchronously. At this time, the racks 6 extend to the outside of the housing 3. While the racks 6 extend to the outside of the housing 3, they drive the mounting hook 7 to move synchronously. Then, align the central hole of the paddy field drive wheel 12 with the mounting hook 7 and squeeze the mounting hook 7 inward so that the mounting hook 7 can pass through the central hole of the paddy field drive wheel 12. Refer to Figure 5 as shown. Then place the paddy field drive wheel 12 on the rack 6, release the mounting hook 7, and the mounting hook 7 deforms and restores itself. The mounting hook 7 can limit the paddy field drive wheel 12 to prevent the paddy field drive wheel 12 from slipping off the rack 6. Then the tillage boat can be started, and the paddy field drive wheel 12 can travel to the edge of the paddy field together with the vehicle.

[0042] When the tillage boat reaches the edge of the paddy field, remove the paddy field drive wheel 12 from the rack 6 and the mounting hook 7, and rotate the handwheel 13 counterclockwise so that the handwheel 13 drives the rack 6 and the mounting hook 7 to reset, thus completing the entire operation of mounting the paddy field drive wheel 12.
