Abstract
Description
Technical Field
[0001] This utility model relates to the field of timber harvesting technology, and more specifically, to a timber harvesting wedge that is easy to transport. Background Technology
[0002] Forest harvesting, as a crucial link in the timber production process, is directly related to the rational utilization and sustainable development of forestry resources. Based on the specific objectives and strict requirements of forestry management, it involves the scientific felling of trees. This includes both pre-mature thinning harvesting to promote tree growth and adjust forest stand structure, as well as main felling operations targeting mature and over-mature forests. The main felling aims to obtain timber and create conditions for the regeneration of new forests.
[0003] In the process of logging operations, the auxiliary role of various tools is indispensable, and logging wedges are one of the key tools. Their core function is to precisely control the direction of the tree after it is felled. This is of great significance for ensuring the safety of logging operations, improving operational efficiency, and reducing damage to surrounding forests and the environment. By driving logging wedges into the cuts made when the tree is felled, their supporting force and action force can effectively guide the tree to fall in the predetermined direction, avoiding accidents or unnecessary losses caused by the tree falling out of control.
[0004] However, existing logging wedges require manual hammering to drive them into the tree cuts, which greatly increases the labor intensity of operators. On the other hand, the existing logging wedges are often bulky and irregularly shaped, making them inconvenient to carry and transport at the logging site.
[0005] Therefore, a timber harvesting wedge that is easy to transport is proposed to address the above problems. Utility Model Content
[0006] 1. Technical problems to be solved
[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a timber harvesting wedge that is easy to transport. It can facilitate handling and transportation, and can also replace manual hammering with mechanized drive, effectively reducing the labor intensity of operators.
[0008] 2. Technical Solution
[0009] To solve the above problems, the present invention adopts the following technical solution.
[0010] A timber harvesting wedge for easy transport includes a pallet. A harvesting wedge structure is fixedly connected to the upper end of the pallet by bolts. The upper end of the pallet has multiple gripping holes, and multiple pads are fixedly connected to the lower end of the pallet. The harvesting wedge structure includes a cylinder. A hammering assembly is fixedly connected to the output end of the cylinder. A guide assembly is slidably connected inside the hammering assembly, and a harvesting wedge assembly is slidably connected inside the guide assembly. The cylinder can drive the hammering assembly to move closer to the harvesting wedge assembly, so that the hammering assembly can better provide hammering force to the harvesting wedge assembly.
[0011] Furthermore, the guide assembly includes a positioning housing, the lower end of which is fixedly connected to the upper end of the support plate by bolts. An air pipe connection port is provided on one side of the positioning housing. Slide rails are fixedly connected to both the upper and lower walls of the inner cavity of the positioning housing. At least one limiting pin is slidably connected to the inner surface of the positioning housing.
[0012] Furthermore, the hammering assembly includes a second cylinder, with a hammering block fixedly connected to the output end of the second cylinder. A slider is fixedly connected to both the upper and lower ends of the second cylinder. The hammering block can hammer the logging wedge assembly under the drive of the second cylinder. During logging, there is no need for manual hammering of the logging wedge, which greatly reduces the labor intensity of the workers.
[0013] Furthermore, the harvesting wedge assembly includes a connecting rod, a rubber pad is fixedly connected to the rear end of the connecting rod, sliders are fixedly connected to both the upper and lower ends of the connecting rod, a harvesting wedge head is fixedly connected to the front end of the connecting rod, and at least one limiting hole is provided at the upper end of the harvesting wedge head.
[0014] Furthermore, the inner surfaces of the two sliders are slidably connected to the outer surfaces of the two slide rails, and the inner surface of the limiting hole is slidably connected to the outer surface of the limiting pin.
[0015] Furthermore, the inner surfaces of the two sliders are slidably connected to the outer surfaces of the two slide rails, the rear end of the second cylinder is fixedly connected to the output end of the first cylinder, and the first cylinder is fixedly installed on the rear end of the positioning housing.
[0016] 3. Beneficial effects
[0017] Compared with existing technologies, the advantages of this utility model are:
[0018] (1) This solution enables convenient handling and transportation of logging wedges by setting multiple gripping holes on the pallet and fixing the components together with bolts. During long-distance transportation, gripping the gripping holes facilitates loading or unloading the logging wedges. In complex forest terrain where vehicles cannot enter, gripping the gripping holes facilitates moving the logging wedges, significantly improving the flexibility of the logging wedges. At the same time, multiple pads working with the pallet can effectively prevent the pallet from squeezing the hands of the handler during transportation or handling, improving safety and enhancing the practicality of the logging wedges.
[0019] (2) This solution uses a combination of cylinder one and hammering component to form a mechanized hammering component, which can replace manual hammering. Cylinder one drives the hammering component to approach the harvesting wedge component, and cylinder two drives the hammering block to hammer the harvesting wedge component. No manual hammering force is required, which greatly reduces the workload when using the harvesting wedge. At the same time, the mechanized hammering method can ensure stable force and improve the efficiency of driving the harvesting wedge into the tree cut. Attached Figure Description

[0030] Example 1:
[0031] Please see Figure 1-5 A timber harvesting wedge for easy transport includes a support plate 1. A harvesting wedge structure 2 is fixedly connected to the upper end of the support plate 1 by bolts. Multiple gripping holes 3 are opened at the upper end of the support plate 1. Multiple pads 4 are fixedly connected to the lower end of the support plate 1. The harvesting wedge structure 2 includes a cylinder 21. A hammering assembly 22 is fixedly connected to the output end of the cylinder 21. A guide assembly 23 is slidably connected inside the hammering assembly 22. A harvesting wedge assembly 24 is slidably connected inside the guide assembly 23.
[0032] The cylinder 21 has a model number of SC63×100, a rated working pressure of 0.6MPa, and a stroke of 100mm.
[0033] In this solution, when transporting or handling logging wedges, operators can easily lift the pallet 1 and logging wedge structure 2 through the gripping holes 3 on the pallet 1. The pad strip 4 can prevent the pallet 1 from squeezing the hands, improving the safety of handling. It is convenient for long-distance loading and transportation as well as short-distance manual handling. Through the cylinder 21 and the hammering component 22, the position of the hammering component 22 can be controlled so that it can move along the guide component 23, always maintaining the distance between the guide component 23 and the logging wedge component 24. Through the action of the hammering component 22, the logging wedge component 24 can be easily driven outward and driven into the tree cut to control the direction of the tree falling.
[0034] Please see Figure 2-5 The guide assembly 23 includes a positioning housing 231, a cylinder 21 fixedly installed at the rear end of the positioning housing 231, the lower end of the positioning housing 231 and the upper end of the support plate 1 are fixedly connected by bolts, an air pipe connection port 232 is provided on one side of the positioning housing 231, slide rails 233 are fixedly connected to both the upper and lower walls of the inner cavity of the positioning housing 231, and at least one limit pin 234 is slidably connected to the inner surface of the positioning housing 231.
[0035] The hammering assembly 22 includes a second cylinder 221. The rear end of the second cylinder 221 is fixedly connected to the output end of the first cylinder 21. A hammering block 222 is fixedly connected to the output end of the second cylinder 221. Slider 223 is fixedly connected to both the upper and lower ends of the second cylinder 221. The inner surfaces of the two sliders 223 are slidably connected to the outer surfaces of the two slide rails 233 respectively.
[0036] Cylinder 221 has a model number of SC50×200, a rated working pressure of 0.6MPa, and a stroke of 200mm.
[0037] The harvesting wedge assembly 24 includes a connecting rod 241, a rubber pad 242 fixedly connected to the rear end of the connecting rod 241, and two sliders 243 fixedly connected to both the upper and lower ends of the connecting rod 241. The inner surfaces of the two sliders 243 are slidably connected to the outer surfaces of the two slide rails 233 respectively. A harvesting wedge head 244 is fixedly connected to the front end of the connecting rod 241. At least one limiting hole 245 is provided at the upper end of the harvesting wedge head 244, and the inner surface of the limiting hole 245 is slidably connected to the outer surface of the limiting pin 234.
[0038] The logging wedge is 150mm long with a 30° wedge angle at the front end, making it easy to drive into the tree cut. Its function is to act directly on the tree cut and control the tree's direction of fall.
[0039] When using this solution, first connect cylinder 21 to an external air source, and then connect cylinder 221 to an external air source through air pipe connection port 232 to provide power to cylinder 21 and cylinder 221. At the same time, in the subsequent process, when cylinder 21 pushes cylinder 221 to move, the connecting pipe between cylinder 221 and the external air source can also move along air pipe connection port 232.
[0040] Align the cutting head 244 with the tree cut, pull out the limiting pin 234 to remove the restriction on the cutting head 244, and then start the control cylinder 221. The cylinder 221 drives the hammer block 222 to hammer the rubber pad 242 at the rear end of the connecting rod 241. The rubber pad 242 can isolate the hammer block 222 from the connecting rod 241, playing a buffering role and effectively preventing the two from being damaged by direct impact.
[0041] Under the action of mechanized hammering, the connecting rod 241 will extend forward with the cooperation of the two sliders 243 and the two slide rails 233. At this time, the felling wedge 244 will be slowly driven into the tree cut. Each time the cylinder 221 drives the hammer block 222 to hammer the rubber pad 242, the connecting rod 241 and the felling wedge 244 will extend outward. At this time, the cylinder 21 needs to be activated to drive the hammering assembly 22 to move closer to the felling wedge assembly 24 through the slider 223 along the slide rail 233, so as to ensure that the hammering assembly 22 can accurately hammer the rubber pad 242 every time.
[0042] It should be noted that cylinder 21 and cylinder 221 in this utility model can be supplied with air by an air compressor and controlled by a controller.
[0043] It should be noted that the specific installation methods, circuit connection methods, air circuit connection methods, and control methods of cylinder 21 and cylinder 221 in this utility model are all conventional designs, and will not be described in detail in this utility model.
[0044] Working principle:
[0045] In terms of transportation and handling, the operator can directly grasp the multiple gripping holes 3 on the pallet 1 to lift the pallet 1 and the logging wedge structure 2 above it. The pad strip 4 at the lower end of the pallet 1 can separate the hand from the pallet 1, avoiding the hand being squeezed during handling. This is convenient for loading and unloading during long-distance transportation, and also convenient for short-distance manual handling in complex terrains such as forests.
[0046] During logging operations, the pallet 1 and multiple pads 4 are placed on the ground next to the felled trees and can be fixed using techniques such as ground anchors. Then, cylinder 1 21 is connected to an external air source and connected to the external air source through the air pipe connection port 232 on one side of the positioning housing 231 to provide power support.
[0047] Before starting the operation, align the felling wedge 244 with the tree cut, pull out the limiting pin 234 on the positioning housing 231 to release its restriction on the upper limit hole 245 of the felling wedge 244, start the cylinder 221, and its output end drives the hammer block 222 to move forward and hammer the rubber pad 242 at the rear end of the connecting rod 241. The rubber pad 242 plays a buffering role in this process to prevent the hammer block 222 from directly colliding with the connecting rod 241 and causing damage.
[0048] Under the action of the hammering force, the connecting rod 241 slides forward along the slide rail 233 inside the positioning housing 231 through the sliders 243 at both ends, driving the felling wedge 244 at the front end to gradually drive into the tree cut. After each hammering by the cylinder 221, the connecting rod 241 and the felling wedge 244 will extend outward a certain distance. At this time, the cylinder 1 21 is activated, and its output end pushes the cylinder 221, so that the hammering component 22 moves closer to the felling wedge component 24 through the slider 223 along the slide rail 233, ensuring that the hammering block 222 can accurately act on the rubber pad 242 when it hammers again. When the felling wedge 244 is driven into the required depth, it can act stably on the tree cut, realizing effective control of the tree's falling direction.
[0049] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
