Description

Thin-shell hickory nut branch pulling suit

Technical Field

The utility model relates to the technical field of agriculture and forestry planting equipment, in particular to a thin-shell hickory nut branch pulling set.

Background

The apocarya is a tall and big tree from the United states and North Mexico, and the tree height can reach 50-60 meters. The seedlings generally take 3-5 years to bear fruits. The growth is rapid before the result, the nutrition growth is basically carried out, and the top end advantage is obvious. If premature delivery and hierarchical tree modeling of the trunk are to be achieved, human intervention must be performed and branch pulling is a method commonly used today. At present, in a apocarya orchard, branches are mainly tied on branches by adopting straw ropes, cloth bags and the like, and then are tied on objects such as wood sticks or bamboo chips, or are tied on trees or are nailed on the ground. For branches with the length of more than 2 meters, the branches can be used for standing a ladder or pulled down by a hook, the working efficiency is low, and potential safety hazards exist in high-level operation.

The existing patent technology mainly aims at pulling thick branches, and the equipment structure is complex. For example, for connecting branches and trunks, a telescopic link structure or a wire rope is used, the cost of the whole equipment is relatively high, and when more branches are erected or the growing angle is smaller (at most 7-8 branches are likely to be required to be pulled), the operation process is more complicated and the cost is increased. For example, the patent with the publication number of CN206136744U discloses a fruit tree thick branch pulling device. The technical proposal is as follows: the n-type main body with saw teeth is inserted into the trunk, one end of the limiting block is sleeved with a steel wire sleeve and connected with a steel wire rope, and the limiting block is placed into a limiting hole of the n-type main body. Secondly, a plastic material wrapping sheet is firstly placed on the branch, and the other end of the steel wire rope is buckled on the plastic material in a self-locking mode. The saw teeth on the n-type main body of the scheme can damage the bark of the young tree apocarya after long-time use, and the use of the steel wire rope is very costly for simultaneously carrying out the branch pulling operation of more than ten thousand trees, and also causes great material waste, which is impractical.

Also, for example, chinese patent publication No. CN209995016U discloses a fruit tree branch pulling device. The technical proposal is as follows: the outer side of the tree body is symmetrically clamped with a fastening lantern ring, one side of the lantern ring is fixedly connected through a connecting belt, the other side of the fastening lantern ring is buckled through a buckle belt, the inner side of the fastening lantern ring is symmetrically provided with a matching groove, a fastening block is arranged in the matching groove, two sides of the fastening block are symmetrically fixed with a sliding block, the fruit tree branch pulling device is used for fixing the device on the outer side of the tree body through the buckle belt, the base rod and the extension rod are oppositely stretched, and the positioning of a positioning pin is matched, so that the adjustment and the fixation of the hooking length are realized. The scheme has the problems that: firstly, spare part is many, and the structure is complicated, secondly, the connecting rod is stainless steel material, even use ordinary carbon steel, to the orchard of large planting volume, its material cost is too high yet, and thirdly to the use inconvenience that draws branch simultaneously of many branches of same trunk, can produce the interference between the connecting rod.

Detailed Description

The utility model is further described with reference to the following examples in order to facilitate the understanding of the technical means, the creation characteristics, the achievement of the objects and the effects achieved by the utility model.

Example 1

1-3, a apocarya branch pulling set comprises an apocarya branch pulling device and a lifting rod matched with the apocarya branch pulling device.

The apocarya branch pulling device comprises a hoop 1, wherein the hoop 1 is used as a matrix and is sleeved on a trunk to fix other parts. The hoop 1 is formed by a plurality of knot-shaped structures 11 which are connected end to end. The section structure 11 is a plastic shell, the lower part of which is open and hollow, and the whole body is an arc frame. The head and tail ends of the section structure 11 are respectively provided with tenon and mortise structures with mutually matched shapes, namely, the tenon structure at one end of the section structure 11 is matched with the mortise structure at the other end, so that a plurality of independent section structures 11 are spliced end to assemble an annular hoop-shaped structure, namely, the hoop 1 of the utility model. To accommodate trunks of different diameters and shapes, the dovetail structure in this embodiment is a dovetail 14, and the dovetail 14 is relatively independent and is mounted in an articulated manner to the end of the node structure 11. This allows for a more flexible assembly of the node structure 11, a larger angle of rotation of the ring, and a closer fit to the trunk. Correspondingly, the mortise structure is a dovetail groove 15. In order to prevent the mortise and tenon structure from slipping loose due to axial pulling of the flexible connector 2, it is preferable that the sliding direction of the mortise and tenon structure is set to be radial, i.e., a direction substantially perpendicular to the pulling direction of the flexible connector 2.

In order to improve the fastening degree of the hoop 1 on the trunk and avoid the hoop 1 from sliding upwards by being pulled by the pulling force of the pulling branch, an anti-slip layer 16 is arranged between the hoop 1 and the trunk in the embodiment. The anti-slip layer may be a separate ring-shaped washer, for example, made of coarse textile, or may be provided as an anti-slip pad or anti-slip pattern integrally formed on the inner side of the node structure 11.

Another scheme for preventing the side slip of the hoop 1 is as follows: an ear plate (not shown in the figure) is arranged on the upper surface of 2 or 3 node structures 11 which are equidistantly distributed, a distance control rod is respectively hinged on the ear plate, and the other end of the distance control rod is fixed at the joint of the trunk and the branches (the bifurcation position of the trunk of the tree body). The aim is that: the hoop 1 is propped downwards by using the distance control rod based on the junction of the trunk and the branches as a bearing point of force, so that the hoop 1 is prevented from sliding upwards. The distance control rod can be formed by adopting a telescopic rod, namely a rod and sleeve structure which are mutually nested. The positioning mode of the telescopic umbrella rod can be referred to for positioning between the rod and the sleeve, and the telescopic positioning is in the prior art and is not repeated.

The node structure 11 is further provided with a first hole 13, and the first hole 13 is a hole structure formed on the node structure 11. One end of the flexible connector 2 is connected to the first hole 13, and the other end is connected to the hook 3. In the embodiment, the nylon rope with the diameter of 1-3mm is adopted as the flexible connector 2, and the nylon rope is made of polyamide material, so that the nylon rope has the advantages of no toxicity, light weight, excellent mechanical strength, wear resistance and good corrosion resistance, and is suitable for being used as a branch pulling material in the field. Compared with the prior art adopting a mode of pulling by a support rod, the flexible ropes can be mutually wound, and the upper end and the lower end do not need to be on the same straight line, so that when the ropes needing to be pulled are too many and are arranged too densely, the hard space position interference does not exist between the ropes, and the traction effect is respectively exerted. The nylon rope is low in price, light in weight and low in use cost, and can not increase trunk supporting load, so that more branch folding phenomena in windy weather are avoided.

The hook 3 is hung on the branch as a structure for directly sleeving the branch. In the prior art, a circular cross section hook is generally adopted, and in order to increase the friction force of the circular cross section and avoid the damage of the branch epidermis caused by larger pressure intensity due to the contact of the circular cross section hook and the branch line, a gasket is generally lined on the inner side surface. However, the complexity of the equipment is further increased, the use cost of the equipment is gradually increased, and the popularization and promotion of the equipment are limited. In order to solve the above-described problem, the hooks 3 in the present embodiment are provided in a sheet-like structure, and are bent in a hook shape as a whole. The sheet structure can be made of metal sheets, and compared with a round section hook, the sheet structure greatly saves materials, reduces the comprehensive weight of branch pulling equipment and reduces the load of branches. The hooks 3 of the lamellar structure form a surface contact with the branches, drastically reducing the pressure on the epidermis of the branches, generally without the bark being damaged by compression. The tail of the hook 3 is provided with a second hole 31 for connecting the flexible connector 2. When in use, the rope takes the hoop 1 as a matrix, and the pulling of the branches is realized through the pulling hook 3.

Because the diameters of the trunks are different, in order to adapt to the trunks as much as possible, the hoop 1 is tightly sleeved on the trunks, and a section of tightness-adjustable structure 12 is arranged on the hoop 1 in the embodiment. The two ends of the tightness-adjustable structure 12 are fixedly connected with the knot-shaped structures 11 at the head part and the tail part respectively, so that the two structures form a serial whole. The body of the tightness-adjustable structure 12 is a strip, and buttons 12a and buttonholes 12b are arranged on the strip. The buttonholes 12b are plural and are circumferentially spaced apart. When in use, the button 12a is jointed with the buttonholes 12b at different positions to realize the tightness adjustment of the hoop 1.

Referring to fig. 5 and 6, as a further component of the kit, a lifting lever is used to lift the hook 3 to the branch-pulling position. The lifting rod comprises a rod sleeve 4, and an end block 40 is fixedly arranged at the upper end part of the rod sleeve 4. The other end of the end block 40 is provided with a buckling groove 41, and the inner side surface of the buckling groove 41 is provided with an inner groove 42 which is matched with the tail shape of the hook 3. When the hook 3 is used, the tail part of the hook 3 which is connected with the rope in advance is inserted into the matched inner groove 42, then the hook 3 is lifted to the branch pulling position by holding the lifting rod by hand, the lifting rod is retracted downwards when the hook 3 is firmly buckled on the branch 2, and the tail part of the hook 3 is separated from the inner groove 42. The hook 3 of the next branch pulling position is then lifted. In order to avoid that the rope is also clamped in the inner groove 42 after the hook 3 is inserted into the inner groove 42, the clamping groove 41 is arranged into a U-shaped structure, and the avoidance space formed by the U-shaped structure extends to the tail part of the hook 3, so that a complete passage for the rope connected with the second hole 31 is formed.

The lower end of the rod sleeve 4 is in sliding fit with the telescopic rod 5, and the telescopic rod 5 can extend out relative to the rod sleeve 4 so as to prolong the length of the lifting rod.

The telescopic rod 5 and the rod sleeve 4 are positioned through a hole shaft matching structure arranged along the length direction. Specifically, a row of positioning holes 43 are formed in the rod sleeve 4, an elastic telescopic column 45 tensioned by a spring 44 is protruded on the telescopic rod 5, and telescopic positioning is achieved based on the cooperation of the elastic telescopic column 45 and the positioning holes 43 of the rod sleeve 4.

Example 2

In another possible embodiment, the node structure 11 is made of rubber having a certain elasticity. The segment structures 11 are solid rubber blocks, and the mutually-jointed end surfaces of the segment structures still adopt a mortise-tenon structure. Because the structure is used in the field, the rubber surface is easy to age to a certain extent, and the aging structure can strengthen the combination friction force and the combination strength of the mortise and tenon structure. The node structure 11 is prevented from slipping off the frame under traction of the flexible connector 2. And this friction is further enhanced with the degree of aging.

Because the rubber material itself has certain elasticity, when a plurality of festival form structures 11 combine each other, whole elasticity is great, can save the use of elasticity adjustable structure 12 to optimize the structure setting, reduce equipment complexity.

Further, the tenon is not easy to hinge on the rubber material, and the integrally formed section structure 11 (comprising the tenon) has certain elasticity along the circumferential rotation, so that the arrangement of a hinge structure is saved, the structure arrangement is further optimized, and the equipment complexity is reduced.

In order to improve the bonding strength between the tenon and the mortise, a layer of metal net can be embedded in the inner side wall of the mortise, and the problem that the tenon-mortise structure is easy to slip in the initial stage of forming the section structure 11 is overcome by utilizing friction force caused by mesh points.

Example 3

Referring to fig. 4, in another possible embodiment, the node structures 11 are bolted together. Because the mortise and tenon joint mode is adopted, relative dislocation of the section structures 11 in the mortise and tenon sliding connection direction cannot be avoided, when the large wind and snow weather is met, the branch pulling force is too large, the section structures 11 are still prone to being scattered, and the connection mode between the section structures 11 is replaced by the bolt connection in the embodiment.

Specifically, the bodies of the node structures 11 are arc-shaped block structures, bolt holes 17 are formed in the head end and the tail end of each of the arc-shaped block structures, and a stud 18 is connected with the bolt holes 17 on opposite sides of two adjacent node structures 11 respectively, so that a plurality of node structures 11 are connected in series to form a hoop.

The node structure 11 may be made of any suitable material, preferably a rubber material having elasticity, and may have any side surface as a contact surface with the trunk because the rubber material may be bent at will. The inner wall of the bolt hole is formed by an embedded metal thread sleeve.

In order to avoid that when the node structure 11 rotates to a certain angle, one end of the first hole 13 is attached and plugged by the trunk, so that the flexible connector 2 cannot be conveniently plugged onto the node structure 11, a circle of ring grooves 19 are arranged in the middle of the node structure 11 in the embodiment, and the flexible connector 2 can pass through the space between the trunk and the node structure 11 by the clearance avoided by the ring grooves, so that the plugging operation is performed. The bending elasticity of the node structure 11 is better because the diameter of the middle part of the node structure 11 is smaller.

Example 4

In another possible embodiment, the buttons 12a and the buttonholes 12b are multiple and are circumferentially spaced apart. If only one button 12a is adopted to correspond to a plurality of buttons 12b, when the button 12a is matched with the furthest button hole 12b, the strip which is retracted between the button 12a and the furthest button hole is overlong, a thrown-out redundant structure is formed, and when the button is scraped by external force, the mortise-tenon joint structure between the knot structures 11 is easily pulled and slipped along the radial direction, so that the whole hoop 1 is scattered. In order to avoid the above-mentioned problems, in the present embodiment, a layout arrangement is adopted in which several groups of buttons 12a are adjacently matched with buttonholes 12b. When in use, a plurality of groups of local tightening structures are formed by matching the adjacent buttons 12a and the buttonholes 12b, and the hoop 1 is comprehensively tightened to avoid forming a longer strip throwing part. The uniformity and the beautiful appearance of the hoop 1 are improved.

Example 5

In another possible embodiment, the body structure of the tightness-adjustable structure 12 is two strip structures, the opposite distal ends of which are connected to the head and tail end node structures 11, respectively. The two strip structures are combined with each other by adopting the fastening tape, so that the method is more beneficial to adjusting the binding tension of the trunk.
