[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] In order to solve the technical problem in the prior art that when the shovel of the fertilizer spreader is inserted too deep into the soil, the swing handle and part of the connecting push rod are easily inserted into the soil, which hinders the movement of the swing handle and the connecting push rod, is not conducive to opening the swinging oblique cover, and thus causes the fertilizer to be unable to fall smoothly, the utility model provides a tobacco fertilizer spreading tool, which can effectively avoid the situation where the soil interferes with the barrel and the transmission structure due to drilling too deep into the soil, ensures that the cover body can be smoothly moved to the position of opening the material opening, thereby improving the stability of fertilization.

[0037] See also Figures 1 to 3 , Figure 1 This is a structural schematic diagram of a tobacco fertilizer spreading tool in an embodiment of the present invention, which includes a sleeve 1, a cover 2, a barrel 3, a transmission structure 4 and a reset member 5; the sleeve 1 has a conical end 11, and the outer wall of the conical end 11 is provided with a material opening 11a connected to its inner cavity; the cover 2 is movably mounted on the conical end 11, and has a ground-breaking position with the material opening 11a closed during the movable stroke, and has a material unloading position with the material opening 11a open; the barrel 3 is rotatably arranged in the sleeve 1; the transmission structure 4 is arranged between the barrel 3 and the cover 2, and is used to convert the rotation of the barrel 3 into the movement of the cover 2 switching from the ground-breaking position to the material unloading position; the reset member 5 connects the cover 2 and the sleeve 1, and is used to reset the cover 2 to the ground-breaking position.

[0038] When using the tobacco fertilizing tool provided by the present invention, the cover body 2 is first placed in the soil-breaking position of the material opening 11a of the closed cone end 11, and then fertilizer is fed from the port of the barrel 3 away from the cone end 11, and then the cone end 11 is inserted into the soil, and then the barrel 3 in the sleeve 1 is rotated, and the rotation of the barrel 3 is converted into the movement of the cover body 2 through the transmission structure 4, so that the cover body 2 is switched from the soil-breaking position to the material discharge position to open the material opening 11a of the cone end 11, so that the fertilizer in the barrel 3 is discharged from the material opening 11a into the soil; finally, the cone end 11 is pulled out of the soil. During this process, the cover body 2 can be reset to the soil-breaking position again under the drive of the reset member 5 to facilitate fertilization again. In this way, in this solution, the rotation of the barrel 3 in the sleeve 1 is converted into the movement of the cover body 2, and the transmission structure 4 is placed between the barrel 3 and the cover body 2, that is, the transmission structure 4 is arranged in the tool, thereby effectively avoiding the situation where the soil interferes with the barrel 3 and the transmission structure 4 due to drilling too deep into the soil, ensuring that the cover body 2 can be smoothly moved to the position of opening the material port 11a, thereby improving the stability of fertilization.

[0039] It should be noted that the cover 2 can be configured as a flat plate, a semi-conical shape, or an arc plate, without limitation, as long as the material port 11a can be opened and closed during the movable stroke. Specifically, in this embodiment, the cover 2 is configured in the form of a semi-conical shape to cooperate with the conical end 11 to form a soil-breaking cone, thereby facilitating soil breaking.

[0040] Furthermore, the form of the transmission structure 4 is not limited, as long as it can convert the rotation of the barrel 3 into the movement of the cover 2. In one embodiment, the transmission structure 4 is a spring plate provided on the barrel 3. Before breaking the soil, the spring plate on the barrel 3 is rotated to a position corresponding to the conical end 11, at which time the spring plate is squeezed. After breaking the soil and when the material needs to be unloaded, the spring plate of the barrel 3 is rotated to a position corresponding to the cover 2. The spring plate releases elastic potential energy, which pops open the cover 2 and opens the material port 11a. In another embodiment, the transmission structure 4 includes a first magnet provided on the barrel 3 and a second magnet provided on the cover. By rotating the barrel 3, the polarity of the first magnet is switched, switching from a position where it can attract the second magnet to a position where it repels the second magnet, thereby opening the material port 11a.

[0041] In this embodiment, see Figure 4 and Figure 5 The cover body 2 is rotatably mounted on the cone end 11; the transmission structure 4 includes a transmission block 41 and a driving block 42. The transmission block 41 is arranged on the side of the cover body 2 close to the material port 11a, and is inclined toward the material port 11a along the circumference of the barrel 3 to form a transmission surface 411. The driving block 42 is arranged at one end of the barrel 3 close to the cover body 2, and can slide and press against the transmission surface 411 when rotating with the barrel 3 to switch the cover body 2 from the ground-breaking position to the material unloading position.

[0042] In this embodiment, one end of the cover body 2 is rotatably mounted on the conical end 11, so that during the rotation process, the other end can be brought into contact with and away from the edge of the material opening 11a to close and open the material opening 11a. Specifically, when the barrel 3 rotates, it drives the drive block 42 to slide and press against the transmission surface 411 of the transmission block 41. Since the transmission surface 411 is inclined as described above, the drive block 42 can press against the other end of the cover body 2 in a direction away from the material opening 11a, thereby opening the material opening 11a. The structure is simple, reliable, and easy to operate.

[0043] In one embodiment, see Figures 4 to 6 The transmission surface 411 has a starting end 412 and a switching end 413 located in the circumferential direction of the barrel 3, and the distance from the starting end 412 to the center of the material port 11a is smaller than the distance from the switching end 413 to the center of the material port 11a; a stop block 12 is installed on the inner side of the conical end 11, and the stop block 12 is located on the side of the starting end 412 away from the switching end 413, and is spaced apart from the starting end 412, and the driving block 42 is placed on the side of the stop block 12 close to the starting end 412.

[0044] In this embodiment, the driving block 42 is initially placed between the stopping block 12 and the starting end 412 so as to shorten the rotation stroke of the barrel 3 when feeding is required, thereby improving the fertilization efficiency.

[0045] It should be noted that the arrangement of the reset member 5 is not limited, as long as it can switch the cover body 2 from the unloading position to the ground-breaking position. In one embodiment, the reset member 5 is in the form of a winch motor, whose base is located on the inner side of the cone end 11, and the winch rope is connected to the cover body 2. When the material opening 11a is required, the rope is released, and when the cover body 2 needs to be switched to the ground-breaking position, the rope is retracted. In another embodiment, the reset member 5 is set in the form of a hydraulic cylinder, the base of the hydraulic cylinder is rotatably mounted on the inner side of the cone end 11, and the hydraulic rod is rotatably connected to the inner side of the cover body 2. The hydraulic rod is extended when the material opening 11a needs to be opened, and the hydraulic rod is retracted when the material opening 11a needs to be closed.

[0046] In this embodiment, the reset member 5 is an elastic member, which connects the cone end 11 and the cover 2 to reset the cover 2 from the unloading position to the ground-breaking position.

[0047] In this embodiment, the reset member 5 is configured as an elastic member. That is, the elastic potential energy of the elastic member is used to reset the lid 2 from the position of opening the material opening 11a to the position of closing the material opening 11a. Specifically, in this embodiment, the elastic member is a tension spring, one end of which is connected to the stop block 12 and the other end is connected to the inner side of the lid 2.

[0048] In one embodiment, the end of the barrel 3 away from the cover body 2 extends out of the inner cavity of the sleeve 1, and the tobacco fertilizer spreading tool also includes a rotating handle 6, which is arranged at the end of the barrel 3 extending out of the sleeve 1; the tobacco fertilizer spreading tool also includes a pressing handle 7, which is arranged on the sleeve 1.

[0049] In this embodiment, a rotating handle 6 is provided at one end of the barrel 3 extending from the sleeve 1, so that the fertilizer applicator can hold the rotating handle 6 and rotate the barrel 3, thereby improving convenience. Similarly, a pressing handle 7 is provided on the sleeve 1, so that the fertilizer applicator can move the cone end 11 downward.

[0050] In one embodiment, the sleeve 1 includes a main body tube 13, an adjusting tube 14 and a locking portion 15. One end of the adjusting tube 14 is sleeved on the main body tube 13 and can move axially relative to the main body tube 13. The locking portion 15 is provided between the main body tube 13 and the adjusting tube 14 to limit the axial movement of the adjusting tube 14 relative to the main body tube 13 when the adjusting tube 14 moves to a preset position relative to the main body tube 13; the conical end 11 is located at the end of the adjusting tube 14 away from the main body tube 13, and the barrel 3 extends from the main body tube 13 into the adjusting tube 14.

[0051] In this embodiment, the overall length of the sleeve 1 can be adjusted by adjusting the relative position of the above-mentioned adjustment cylinder 14 on the main cylinder 13, and the main cylinder 13 and the adjustment cylinder 14 are locked by the locking portion 15, so that adjustments can be made according to user needs to improve user experience.

[0052] In one embodiment, the locking portion 15 includes an internal thread provided on the adjustment tube 14 and an external thread provided on the main tube 13 .

[0053] In this embodiment, the adjusting tube 14 is threadedly engaged with the main tube 13 , and the overall length of the sleeve 1 is adjusted by loosening or tightening the adjusting tube 14 , which is simple and convenient to operate.

[0054] In one embodiment, a locking screw hole 14a is provided on the side wall of the adjusting tube 14, and the locking screw hole 14a is located at one end of the adjusting tube 14 close to the main tube 13. The sleeve 1 also includes a locking bolt 16, one end of which can be screwed into the locking screw hole 14a and pressed against the outer wall of the main tube 13.

[0055] In this solution, after the length of the sleeve 1 is adjusted, the locking bolt 16 can be tightened so that the end of the locking bolt 16 is pressed against the outer wall of the main tube 13 to limit the axial movement of the adjustment tube 14 relative to the main tube 13, thereby further improving the stability of the adjustment tube 14 after being locked with the main tube 13.

[0056] In one embodiment, the sleeve 1 further includes a limit pedal 17 . The limit pedal 17 is disposed on the main tube 13 and located on a side of the adjustment tube 14 away from the cone end 11 .

[0057] In this solution, a limit pedal 17 is provided on the main barrel 13. This not only facilitates the fertilizer applicator's stepping on the limit pedal 17 to lower the cone end 11 into the soil, but also allows the limit pedal 17 to limit the depth of the cone end 11, preventing it from drilling too deep into the soil. Specifically, because the adjustment barrel 14 can move axially along the main barrel 13, the distance between the limit pedal 17 and the cone end 11 is adjustable, allowing for flexible adjustment of the drilling depth and improving practicality.

[0058] In one embodiment, see Figures 5 to 7 A limiting groove 11b is provided on the inner side of the cone end 11, and the limiting groove 11b extends along the circumference of the barrel 3. The barrel 3 is provided with a limiting block 31 corresponding to the limiting groove 11b, and the limiting block 31 is located in the limiting groove 11b.

[0059] In this embodiment, when the position of the above-mentioned adjustment cylinder 14 needs to be adjusted, since the limit block 31 of the barrel 3 is placed in the limit groove 11b of the cone end 11, it can synchronously drive the barrel 3 to move axially along the main barrel 13, ensuring that the driving block 42 can cooperate with the transmission block 41.

[0060] In addition, it should be noted that, in one embodiment, the tobacco fertilizing tool further includes a fertilizer box 8, which is provided with a shoulder strap. The fertilizer box 8 is connected to the end of the barrel 3 extending outside the sleeve 1 through a fertilizer pipe. The pipe is provided with a valve to control the amount of fertilizer entering the barrel 3. The specific configuration of the valve is conventional and will not be described in detail here.

[0061] In order to better understand the present invention, the following Figures 1 to 7 The technical solution of the utility model is described in detail:

[0062] The working process is as follows: first, place the cover body 2 in the soil-breaking position of the material opening 11a of the closed cone end 11, then open the valve on the fertilizer pipe, and feed an appropriate amount of fertilizer in the fertilizer box 8 into the barrel 3; then step on the limit pedal 17 to insert the cone end 11 into the soil, and then rotate the barrel 3 in the sleeve 1, so that the driving block 42 slides and presses against the transmission surface 411 of the transmission block 41 to drive the cover body 2 to switch from the soil-breaking position to the material discharge position, open the material opening 11a of the cone end 11, and allow the fertilizer in the barrel 3 to be fed into the soil from the material opening 11a; finally, pull the cone end 11 out of the soil. During this process, the cover body 2 can be reset to the soil-breaking position again under the drive of the elastic member to facilitate fertilization again.

[0063] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
