Description

Technical Field

[0001] The utility model relates to the field of agricultural equipment, in particular to a portable tobacco topping and bud suppressing scissors. Background Art

[0002] During the growth process of traditional flue-cured tobacco cultivation, tobacco plants often show buds and bloom at a certain stage. At this time, the nutrients in the plant body will increase sharply, and the main flow is to the flower organs at the top, resulting in insufficient nutrient acquisition for the middle and lower tobacco leaves. Therefore, it is necessary for growers to timely top and remove side shoots. After topping and removing side shoots, it is also necessary to spray bud suppressants to prevent the regeneration of axillary buds at the vein part, thereby consuming a large amount of nutrients and seriously affecting the yield and quality of tobacco leaves.

[0003] At present, the application methods of chemical bud suppressants provided on the market are mostly manual cup pouring method and smearing method. Among them, although the manual cup pouring method saves manpower, the dosage of the drug is extremely large, resulting in increased costs and ineffective control of the application dosage of the bud suppressant, which affects the growth of tobacco leaves. The smearing method requires the cooperation of various tobacco bud suppressant applicators, which increases the requirements for tobacco farmers' operations, has a large investment in labor costs, and has low production efficiency.

[0004] Therefore, the existing technology needs to be further improved. Content of the Utility Model

[0005] The portable tobacco topping and bud suppressing scissors provided by the utility model solve the problems in the prior art that it is difficult to apply bud suppressant simultaneously during the tobacco topping process, resulting in low work efficiency and increased labor costs.

[0006] The technical solution adopted in this application is as follows:

[0007] This application provides a portable tobacco topping and bud suppressing scissors, which includes a first pruning part and a second pruning part hinged together. The first pruning part includes a first blade and a first handle connected to each other. The second pruning part includes a second blade and a second handle connected to each other. The first blade and the second blade are stacked vertically from top to bottom. A receiving groove is formed on the surface of the second blade away from the first blade, and a water-absorbing block is arranged inside the receiving groove. The surface of the water-absorbing block is flush with the surface where the opening of the receiving groove is located.

[0008] As a preferred embodiment of this application, the portable tobacco topping and bud suppressing scissors further include a liquid inlet assembly and a carrying container. The liquid inlet assembly is arranged between the first handle and the second handle, and both ends of the liquid inlet assembly are respectively connected to the carrying container and the water-absorbing block.

[0009] As a preferred embodiment of this application, a communication channel is formed inside the second blade, and both ends of the communication channel are respectively communicated with the receiving groove and the outside.

[0010] As a preferred embodiment of the present application, the liquid inlet assembly includes a first connecting pipe, a piston part, and a second connecting pipe. The first connecting pipe is placed in the communication channel, and its two ends are respectively connected to the piston part and the accommodating groove.

[0011] As a preferred embodiment of the present application, the piston part includes a piston tube and a push-pull piston. The push-pull piston is arranged inside the piston tube and is slidably connected to the inner wall of the piston tube. One end of the push-pull piston away from the piston tube is provided with a push rod, which is connected to the inner side wall of the second handle. The end of the piston tube away from the push rod is connected to the inner side wall of the first handle.

[0012] As a preferred embodiment of the present application, on both sides of one end of the piston tube close to the first handle, a first one-way door and a second one-way door are provided. The first one-way door is connected to the first connecting pipe, and the second one-way door is connected to the second connecting pipe.

[0013] As a preferred embodiment of the present application, a strap is provided on the surface of the carrying container, and the carrying container can be positioned on the staff's body through the strap.

[0014] As a preferred embodiment of the present application, an elastic member is further provided between the first handle and the second handle.

[0015] As a preferred embodiment of the present application, the water-absorbing block is made of sponge material.

[0016] As a preferred embodiment of the present application, a plurality of positioning protrusions are protruded inward in parallel at the opening of the accommodating groove, and the surface of the positioning protrusion close to the inner bottom wall of the accommodating groove abuts against the water-absorbing block.

[0017] Due to the adoption of the above technical solutions, the technical effects achieved by the present application are as follows:

[0018] 1. The present application provides a portable tobacco topping and bud suppressing scissors. By providing an accommodating groove on the side of the second blade away from the first blade, that is, on the outer side wall of the second blade, and arranging a water-absorbing block in the accommodating groove, the bud suppressing agent can be adsorbed in the water-absorbing block based on the liquid absorption ability of the water-absorbing block. And when the entire bud suppressing scissors perform shearing, the second blade can be on the side that can contact the shearing surface. In this way, when shearing the apical bud, the bud suppressing agent at the water-absorbing block can be used to smear on the shearing surface to preserve the shearing surface and prevent the growth of new apical buds. Compared with the previous method of spraying the bud suppressing agent with one hand and shearing with the other hand, the setting method of the present application can perform the bud suppressing work while shearing, which is more convenient to operate, improves the work efficiency and reduces the labor input.

[0019] 2. As a preferred embodiment of the present application, since the first handle and the second handle need to be pressed during pruning to drive the first blade and the second blade to cut, the liquid inlet assembly is arranged between the first handle and the second handle, so that during pruning, by pressing, the bud inhibitor can flow along the direction of the bearing container, the piston part and the water absorption block, and thus the water absorption block can be continuously replenished with the bud inhibitor while cutting. The operation is simple, and the wetting time of the water absorption block can be prolonged, so that the working time can be extended and long-time work can be guaranteed.

[0020] 3. As a preferred embodiment of the present application, the present application is detachably connected between the bearing container and the second connecting pipe, so as to facilitate timely replacement after the bud inhibitor in the container is exhausted. Moreover, by arranging a strap on the surface of the bearing container, the container can be arranged on the user's arm, back or waist etc. through the strap during use, so that the staff can carry the bearing container more conveniently during the cutting process, further optimizing the use experience.

[0021] 4. As a preferred embodiment of the present application, since the accommodation groove is opened on the outer side wall of the second blade, directly setting the water absorption block in the accommodation groove may cause the water absorption block to fall off during use. Therefore, the present application uses sponge material for the water absorption block, so that the water absorption block has a certain elasticity. Then, a slightly larger water absorption block can be arranged in the accommodation groove to play a certain supporting role through the elastic force of deformation. Moreover, by arranging a plurality of positioning protrusions at the opening of the accommodation groove, the positioning protrusions can play a certain role in carrying and positioning the water absorption block, further reducing the phenomenon of the water absorption block falling off.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited by the specific embodiments disclosed below.

[0034] In this application, unless otherwise clearly defined and limited, terms such as "install", "connect", "join", "fix", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a communication connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal connection of two elements or the interaction relationship between two elements.

[0035] In this application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0036] As Figure 1 and Figure 2 shown, this application provides a portable tobacco topping and bud suppressing shear, which includes a first pruning part 10 and a second pruning part 20 that are hinged. The first pruning part 10 includes a first blade 11 and a first handle 12 that are connected. The second pruning part 20 includes a second blade 21 and a second handle 22 that are connected. The first blade 11 and the second blade 21 are stacked from top to bottom in the vertical direction. A receiving groove 23 is formed on the surface of the second blade 21 away from the first blade 11. A water-absorbing block 24 is arranged inside the receiving groove 23, and the surface of the water-absorbing block 24 is flush with the surface where the opening of the receiving groove 23 is located.

[0037] Among them, for the hinge structure of the first pruning part 10 and the second pruning part 20, its main structure can adopt a common pruning knife structure, such as Figure 1 shown, a scissor structure with a cross arrangement is used to prune the terminal bud. Both the first handle 12 and the second handle 22 have a stepped structure, so that the first handle 12 and the second handle 22 present a Z-shaped structure and are hinged at the stepped structure. Since the pruning knife structure presented by the hinge of the first pruning part 10 and the second pruning part 20 is roughly the same as the appearance, principle, and structure of the pruning knife in the prior art, this application will not elaborate on it here.

[0038] Furthermore, the portable tobacco topping and bud suppressing shear further includes a liquid inlet assembly 30 and a carrying container 40. The liquid inlet assembly 30 is arranged between the first handle 12 and the second handle 22, and both ends of the liquid inlet assembly 30 are respectively connected to the carrying container 40 and the water-absorbing block 24.

[0039] Among them, an elastic member 50 is also arranged between the first handle 12 and the second handle 22. The elastic member 50 can adopt a spring structure. Since it is necessary to press the first handle 12 and the second handle 22 during cutting, the arrangement of the elastic member 50 can apply a reverse force when the first handle 12 and the second handle 22 are released, so that the first handle 12 and the second handle 22 return to their original positions, which is convenient for operation.

[0040] Further, a communication channel 25 is provided inside the second blade 21, and both ends of the communication channel 25 are respectively communicated with the accommodation groove 23 and the outside. Among them, as Figure 2 shown, the communication channel 25 is strip-shaped and directly passes through the channel inside the second blade 21, so as to facilitate connection with the liquid inlet assembly 30, so that the carrying container 40 supplies liquid to the water absorption block 24 inside the accommodation groove 23.

[0041] As Figure 1 and Figure 2 shown, the liquid inlet assembly 30 includes a first communication pipe 31, a piston part 32 and a second communication pipe 33. The first communication pipe 31 is placed in the communication channel 25, and both ends are respectively communicated with the piston part 32 and the accommodation groove 23. For the first communication pipe 31 and the second communication pipe 33, a flexible hose structure that can be bent can be adopted to facilitate connection and bending, so as to adapt to the working conditions at various angles of the staff holding the bud inhibitor scissors; and, for the first communication pipe 31, it can be inserted into the communication channel 25, and of course it can also be pulled out of the communication channel 25. In order to facilitate plugging and unplugging, the diameter of the communication channel 25 can be set slightly larger than the diameter of the first communication pipe 31, so as to inject the bud inhibitor into the accommodation groove 23 through the first communication pipe 31.

[0042] In a preferred embodiment, as Figure 1 shown, the piston part 32 includes a piston pipe 321 and a push-pull piston 322. The push-pull piston 322 is arranged inside the piston pipe 321 and is slidably connected to the inner wall of the piston pipe 321. A push rod 34 is arranged at one end of the push-pull piston 322 away from the piston pipe 321, and the push rod 34 is connected to the inner side wall of the second handle 22. One end of the piston pipe 321 away from the push rod 34 is connected to the inner side wall of the first handle 12.

[0043] Specifically, the piston part 32 can be arranged out of position with the elastic member 50. For example, Figure 1 shown, the elastic member 50 can be arranged in front of the piston part 32, so as to input the bud inhibitor through the piston part 32 when pressing, and the arrangement of the elastic member 50 facilitates the return of the push-pull piston 322 of the piston part 32.

[0044] Further, first one-way doors 35 and second one-way doors 36 are arranged on both sides of one end of the piston pipe 321 close to the first handle 12. The first one-way doors 35 are communicated with the first communication pipe 31, and the second one-way doors 36 are communicated with the second communication pipe 33.

[0045] During use, the bud pruning shears open, that is, the first handle 12 and the second handle 22 expand, causing the first blade 11 and the second blade 21 to separate from each other, preparing for the cutting operation of the bud pruning shears. At this time, the expansion of the first handle 12 and the second handle 22 pulls the push-pull piston 322 outwards, thereby extracting the bud inhibitor in the carrier container 40 through the change in pressure and entering the piston tube 321 through the second connecting pipe 33 and the second one-way valve 36. When pruning the apical bud, the operator presses the first handle 12 and the second handle 22, causing the first blade 11 and the second blade 21 to gradually merge from the separated state, closing the bud pruning shears, and then cutting the apical bud with the blades. During this process, the relative movement of the first handle 12 and the second handle 22 causes the push-pull piston 322 to compress inwards in the piston tube 321, causing the pressure in the piston tube 321 to change again, and pushing the squeezed liquid through the first one-way valve 35 into the first connecting pipe 31 until it is absorbed by the water-absorbing block 24 in the input value accommodating groove 23, enabling the water-absorbing block 24 to always be in a moist state and ensuring the normal application of the bud inhibitor.

[0046] It should be noted that the first one-way valve 35 and the second one-way valve 36 referred to in this application have the ability of one-way conduction. The principle of this ability is the same as that of structures such as spray bottles and water guns that can spray water through a piston structure. In order to ensure the effect of one-way conduction, when designing the equipment of this application, it is necessary to reasonably set the diameter, length, and position of the first connecting pipe 31 and the second connecting pipe 33 to ensure the one-way flow of the liquid. The diameter of the water outlet of the first connecting pipe 31 can be appropriately reduced, and it can be set at a certain distance and angle from the piston part 32 and the carrier container 40.

[0047] As Figure 1 shown, in an alternative embodiment, a strap 41 is provided on the surface of the carrier container 40, and the carrier container 40 can be positioned on the operator's body through the strap 41. For example, the carrier container 40 can be tied to the user's arm through the strap 41 to make the operation more convenient and cover the entire bud pruning shears.

[0048] For the shape of the carrier container 40, a bottle-shaped or barrel-shaped cylindrical structure can be adopted, and the second connecting pipe 33 can be detachably connected to the carrier container 40, for example, by screw connection, so as to facilitate timely replacement when the bud inhibitor in the carrier container 40 is exhausted or the carrier container 40 is damaged.

[0049] Furthermore, the water-absorbing block 24 can be made of sponge material, which not only has good water-absorbing performance, but also has low cost and is easy to replace. The accommodating groove 23 can adopt a square structure. Moreover, since the sponge material also has a certain elasticity, during assembly, a water-absorbing block 24 with a slightly larger area than the accommodating groove 23 can be used. It is compressed and placed into the accommodating groove 23 through its elasticity, and after placement, due to the shape recovery of the elasticity of the water-absorbing block 24, the four sides of the water-absorbing block 24 abut against the inner wall of the accommodating groove 23, thereby improving the positioning effect to a certain extent.

[0050] In addition, as Figure 2 shown, a plurality of positioning protrusions 24 can be provided protruding inwardly in parallel at the opening of the accommodating groove 23. The surface of the positioning protrusion 24 close to the inner bottom wall of the accommodating groove 23 abuts against the water-absorbing block 24, which can further support and position the water-absorbing block 24 placed in the accommodating groove 23 and reduce the occurrence of the phenomenon that the water-absorbing block 24 falls off.

[0051] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the differences between each embodiment and other embodiments are emphasized.

[0052] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
