Description

Technical Field

[0001] The invention relates to the technical field of forestry sampling, and in particular to a sample collecting device used for forestry resource exploration. Background Art

[0002] Forestry refers to the production department that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forests to play a protective role. When conducting forestry surveys, it is necessary to sample vegetation. After sampling, the local forestry growth status can be determined through detection and analysis.

[0003] Traditional forestry resource sampling usually relies on manual data collection, such as measuring the height, diameter at breast height, crown, tree species, etc. of trees. This process is not only very cumbersome, but also consumes a lot of time and manpower. Due to factors such as human error and fatigue, the accuracy and consistency of the measurement results are difficult to guarantee. Traditional ground sampling can usually only cover a limited area, and in some remote or complex terrain areas, the sampling difficulty and cost are high, making it difficult to achieve comprehensive and accurate resource surveys and monitoring. Traditional forestry resource sampling generally relies on manual surveys, and the collected data often takes a long time to be sorted and analyzed. Therefore, the timeliness and real-time nature of the data are poor. Forestry resources are often scattered, and many forests are distributed in complex terrains (such as mountainous areas, swamps, etc.). Traditional equipment is difficult to adapt to these environments for effective sampling, especially in difficult mountainous and dense forest areas. Traditional sampling equipment usually relies on periodic ground surveys in the monitoring and evaluation of forest resources, and cannot provide real-time dynamic monitoring. This leads to the lag in changes in forest resources, and it is impossible to find problems in time and take corresponding measures. Traditional ground sampling equipment is often expensive.

[0022] The present invention provides a sample collection device for forestry resource exploration, which has the following beneficial effects:

[0023] 1. The present invention has a convenient sampling operation effect: the device combines an extended fixing rod, a portable control mechanism and a sample fixing mechanism, so that the operator can conveniently carry the device to the sampling site and perform rapid sampling through the portable control mechanism. The structural design of the extended fixing rod and the fixing mechanism ensures that the device can be flexibly adjusted according to different sampling heights, greatly improving work efficiency and reducing physical exertion during the sampling process. During the sampling process, the sample fixing mechanism of the device can automatically clamp the vegetation sample to be collected through the portable control mechanism, and work in conjunction with the cutting and extraction mechanism to complete the cutting of the vegetation sample. Automated clamping and cutting not only improves the accuracy of sampling, but also reduces the complexity of manual operation, ensuring the efficiency and accuracy of each sampling. The device ensures that the cut vegetation sample can fall smoothly and be guided into the collection bucket through the linkage opening and closing components and the extended flow channel structure.

[0024] 2. The present invention has the technical effect of rapid repair of vegetation: wound sealing during the cutting process is a highlight of the device. When the sample fixing mechanism clamps the vegetation and cuts it, the cut part will be sprayed with a wound sealant simultaneously. This design effectively reduces the damage after vegetation cutting, accelerates the self-repair process of vegetation, reduces environmental damage, avoids possible ecological damage after vegetation sampling, and meets the requirements of ecological protection. The wound sealant can also be quickly and accurately injected into the cut part through the extended flow channel and the output tube to ensure that the gap after vegetation cutting is repaired in time. This design further improves the degree of automation of the equipment, reduces manual intervention, and improves sampling efficiency.

[0025] 3. The present invention has a design that saves effort and improves comfort: the equipment is specially designed with force-applying handles, positioning pins and other structures, so that the force application during the sampling process is more stable and labor-saving. Through the locking control mechanism and the switching push arm, the clamping angle can be automatically locked to reduce the long-term pressing and force application of personnel, thereby effectively reducing operating fatigue and improving comfort. It is especially suitable for long-term field work. The extension auxiliary mechanism (including small-diameter sleeve rods and large-diameter sleeve rods) allows the equipment to be operated at different sampling heights, and through the linkage of manual control and traction ropes, the highly precise adjustment of the sampling equipment is achieved. Through this height and distance adjustability, the equipment adapts to the sampling needs of various types of vegetation in different woodland environments, and improves the versatility and flexibility of sampling.

[0026] 4. The present invention has precise control and positioning functions: through precise control mechanisms such as positioning pins, locking ratchets, and engaging gear rods, the equipment can achieve precise clamping and fixing during operation, effectively avoiding displacement or damage of samples during sampling. At the same time, this precise control method makes the cutting and collection process of vegetation samples more stable and reliable. The structural design of the equipment enables it to adapt to a variety of vegetation types and different sampling heights, and is widely used in various types of forestry surveys and explorations, especially in diverse woodland environments. It can efficiently perform sampling tasks. The height adjustment function and extension mechanism of the equipment ensure that it can work smoothly even under complex vegetation density and terrain conditions.

After the arc-shaped rack 66 included in the cutting and extraction mechanism is started, the micro motor 67 installed at its output end is driven to complete the clockwise and counterclockwise rotation. The arc-shaped rack 66 meshing with the micro motor 67 drives the arc-shaped slide bar 65 to slide back and forth inside the limiting slide groove 64 provided on the arc-shaped inlay seat 1 61. The control motor installed at the bottom forms a cutting force through reciprocating motion. The control motor is arranged on the flexible bottom wall inside the arc-shaped inlay seat 1 61. Through the flexible characteristics, the vibration generated by the motor itself is alleviated, thereby reducing the generation of noise and the impact of noise on the user. The part of the vegetation sample to be collected is cut and finally falls onto the guide inclined plate structure installed on the collection bucket 38 and is guided into the collection bucket 38.

[0048] Please see attached Figure 1 -Attached Fig.14The synchronous repair mechanism 7 is located on the extended fixed rod 1, and cooperates with the L-shaped linkage arm 33 and the arc-shaped inlay seat 62 to transport and apply wound sealant to the cut plant part. The synchronous repair mechanism 7 includes a fixed frame 71, and the interior of the fixed frame 71 is fixedly connected with a storage tank 72. The bottom wall of the extended fixed rod 1 is fixedly connected with an extended flow channel 73, and the output port of the extended flow channel 73 is fixedly connected with an output pipe 74, and the output pipe 74 extends to the top of the arc-shaped inlay seat 62. A linkage opening and closing component 75 for quantitative feeding is provided between the extended flow channel 73 and the extended fixed rod 1. A filling pipe 76 is provided at the filling port of the storage tank 72. The linkage opening and closing component 75 includes a fixed slide bar 761, which is slidably connected to the bottom wall of the extended fixed rod 1 and extends into the extended flow channel 73. The fixed slide bar 761 is fixedly connected to the side wall of the traction rope 37, and one end of the fixed slide bar 761 located inside the extended flow channel 73 is fixedly connected with a linkage partition plate 762. The movable partition plate 762 is slidably connected to the inner wall of the extended flow channel 73, and the side wall of the linkage partition plate 762 is provided with an input groove 763. When the personnel grips and presses the control, the traction rope 37 moves inside the extended fixed rod 1, and at the same time drives the linkage opening and closing component 75 structure to operate inside the extended flow channel 73 along the traction rope 37. The fixed slide bar 761 included in the linkage opening and closing component 75 moves on the slide groove between the traction rope 37 and the extended flow channel 73. The fixed slide bar 761 simultaneously drives the linkage partition plate 762 fixed inside the extended flow channel 73 to slide, so that the input groove 763 provided on the linkage partition plate 762 and the drainage channel are connected with each other, so that a clear channel is formed between the storage tank 72 and the extended flow channel 73, and the wound sealant stored in the storage tank 72 enters the extended flow channel 73 along the extended flow channel 73, and is injected into the vegetation cutting gap by the extended flow channel 73 and the output pipe 74, so that the vegetation gap can be repaired at the first time of being cut.

[0049] Working principle: First, the forestry survey and sampling equipment can quickly and conveniently sample forestry vegetation. The collectors can carry the equipment directly to the forestry sampling area. The whole equipment is installed and fixed to each other through the extension fixing rod 1. The sample fixing mechanism 3 and the portable control mechanism 4 are respectively installed at the two ends of the extension fixing rod 1. At the same time, the sample fixing mechanism 3 and the extension fixing rod 1 can also adjust the collection height distance through the extension auxiliary mechanism 2, and the portable control mechanism 4 is controlled to drive the sample fixing mechanism 3 to cut and clamp the vegetation sample used. Finally, the locking and labor-saving mechanism 5 installed on the sample fixing mechanism 3 is used for cutting and collection. While the sample fixing mechanism 3 is operating and clamping, the cutting mechanism installed on the extension fixing rod 1 will be opened synchronously. The cutting and extraction mechanism 6 is used to spray wound sealant on the cut part of the vegetation, so that the vegetation can be quickly repaired after cutting and sampling. According to the collection height of different vegetation, the collector directly operates the extension auxiliary mechanism 2 installed on the extension fixing rod 1. The small-diameter sleeve rod 21 and the large-diameter sleeve rod 22 included in the extension auxiliary mechanism 2 are mutually sleeved. The small-diameter sleeve rod 21 is fixed on the extension fixing rod 1, and the large-diameter sleeve rod 22 is installed on the portable control mechanism 4 of the manual operation part. The traction rope 37, which is mainly used as the control connection between the portable control mechanism 4 and the sample fixing mechanism 3, also extends into the large-diameter sleeve rod 22 at the same time, and is sleeved with the traction sleeve rod 23 included in the extension auxiliary mechanism 2, and the card beads installed on the outer end of the traction rope 37 are clamped on the side wall of the traction sleeve rod 23 The internal threaded sleeve 28 installed inside the positioning sleeve 26 is opened to drive the internal threaded sleeve 28 installed at the output end to rotate. As the internal threaded sleeve 28 rotates, the fixing screw 27 connected to the internal thread groove of the internal threaded sleeve 28 will pull and drag the traction sleeve 25 to slide on the inner wall of the positioning sleeve 26. At the same time, the traction sleeve 25 drives the small-diameter sleeve rod 21 to slide on the inner wall of the large-diameter sleeve rod 22, so that the small-diameter sleeve rod 21 can fix the extension of the fixing rod 1, the portable control mechanism 4, the locking and labor-saving mechanism 5 and the cutting and extracting mechanism 6. The small-diameter sleeve rod 21 can be pushed out or retracted to achieve the ability of distance adjustment. As the small-diameter sleeve rod 21 is pushed out and retracted, the traction rope 37 slides inside the traction sleeve rod 23 at the same time, and According to the sliding distance, the card beads of the traction rope 37 are engaged in the hole grooves of the traction sleeve rod 23 at the corresponding distance, so that the traction rope 37 and the traction sleeve rod 23 can achieve traction without affecting the adjustment of the distance. The user holds the fixed handle 42 with one hand, and improves the collection stability by grasping the stable handle 24 with the other hand. By squeezing and pressing the force-applying handle 44, the force-applying handle 44 drives the second positioning pin 43 to rotate on the fixed handle 42. While the force-applying handle 44 rotates, it drives the traction sleeve rod 23 installed through the third positioning pin 45 and cooperates with the displacement of the second traction rope 37, so that the traction rope 37 installed at the other end of the traction sleeve rod 23 moves telescopically inside the extended fixed rod 1. The movement of the traction rope 37 drives the sample fixing mechanism 3 to operate.The linking rope sleeve 1 36 fixed at the other side end of the traction rope 37 drives the fixed traction slide column 35 to slide in an arc along the arc groove 32 installed on the positioning clamping arm 31 when the traction rope 37 moves. The arc sliding of the traction slide column 35 causes the docked L-shaped linkage arm 33 to rotate at a small angle along the installed positioning pin 1 34, thereby forming a clamping force with the positioning clamping arm 31 and clamping the vegetation sample to be collected. When the personnel squeezes the portable control mechanism 4, the locking force-saving mechanism 5 is also activated. The rotation of the positioning pin 2 43 drives the locking ratchet 55 installed inside the component shell 51 to rotate along the miniature bearing 54. The rotation of the locking ratchet 55 drives a group of meshing engaging gear rods 56 to rotate, and the reset card corresponding to the group of engaging gear rods 56 The spring 57 always allows the group of engaging gear rods 56 to resume the meshing state with the locking ratchet 55. Due to the meshing of the group of engaging gear rods 56, the locking ratchet 55 cannot rotate, and then the positioning pin 43 and the force-applying handle 44 cannot rotate, thereby realizing automatic locking of the clamping capacity. The switching push arm 53 can also be rotated to rotate the fan-shaped switching block 58 fixed at the rear end of the switching push arm 53 rotating shaft, so that the group of engaging gear rods 56 originally stacked on the top of the fan-shaped switching block 58 is meshed with the locking ratchet 55 under the action of its corresponding reset spring 57, while the other group of engaging gear rods 56 is stacked on the top of the protruding part of the fan-shaped switching block 58 and disengaged from the locking ratchet 55, and the locking ratchet 55 is then reversely locked, reducing the time for personnel to apply force and saving time during cutting. During the cutting and sampling process, the clamping angle can be temporarily locked to reduce the pressing time of personnel, so as to achieve the purpose of labor saving and improve the comfort during sampling. When the arc-shaped bearing pad 63 arranged on the arc-shaped inlay seat 2 62 holds the vegetation sample to be collected, the cutting and extraction mechanism is started at the same time. After the arc-shaped rack 66 included in the cutting and extraction mechanism is started, the micro motor 67 installed at its output end is driven to complete the clockwise and counterclockwise rotation. The arc-shaped rack 66 meshing with the micro motor 67 drives the arc-shaped slide bar 65 to slide back and forth in the limiting slide groove 64 opened on the arc-shaped inlay seat 1 61. The control motor installed at the bottom forms a cutting force through reciprocating motion. The control motor is arranged on the flexible bottom wall inside the arc-shaped inlay seat 1 61. Through the flexible characteristics, the cutting force is slowed down. The vibration generated by the motor itself is eliminated, thereby reducing the generation of noise and the impact of noise on users. The vegetation sample part to be collected is cut and finally falls onto the guide inclined plate structure installed on the collection bucket 38 and is guided into the collection bucket 38. While the personnel is holding and pressing the operation, the traction rope 37 moves inside the extension fixed rod 1, and at the same time drives the linkage opening and closing component 75 structure to operate inside the extension flow channel 73 along the traction rope 37. The fixed slide rod 761 included in the linkage opening and closing component 75 moves on the slide groove between the traction rope 37 and the extension flow channel 73. The fixed slide rod 761 simultaneously drives the linkage partition plate 762 fixed inside the extension flow channel 73 to slide, so that the input through groove 763 set on the linkage partition plate 762 and the drainage channel are connected with each other.A clear channel is formed between the storage tank 72 and the extended flow channel 73, and the wound sealant stored in the storage tank 72 enters the extended flow channel 73 along the extended flow channel 73, and is injected into the vegetation cut gap through the extended flow channel 73 and the output pipe 74, so that the vegetation gap can be repaired as soon as it is cut.
