[0014] The present invention also provides a forestry tree automatic counting method, comprising the following steps:

[0015] S1. Hold the touch rod, align the protection block at its end point with the tree to be counted and move it;

[0016] S2. When the protection block contacts the tree, the protection block contacts the tree through the buffer rubber pad, and then a plurality of sensors on the buffer rubber pad contact the tree;

[0017] S3. After receiving the signal, the sensor transmits the signal to the controller, which converts the signal into a counting signal, so that the display content at the counter changes, that is, the current display number is increased by one, thereby completing the counting operation of the trees.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) In order to avoid the phenomenon of missing numbers due to incomplete contact between the sensor and the tree during the counting process, the sensor continues to move the touch rod after it has contacted the tree so that its end point is in full contact with the tree to avoid the above phenomenon. This means that the touch rod itself and the contact force with the tree are increased, so that the touch rod moves at the upper limit of the auxiliary cylinder, so that the buffer pad and the auxiliary spring are in a buffering state, which is used to increase the contact force between the sensor and the tree, so that the two are in full contact, avoiding omissions during the counting process, and improving the counting accuracy of the device. At the same time, through the above buffering force, it can avoid the excessive contact force between the touch rod and the tree, which may cause the touch rod to be used. In order to prevent damage or breakage from occurring during counting, the feeler rod and the tree are flexibly connected, that is, softly connected, to protect the feeler rod, thereby preventing the feeler rod from being seriously worn during frequent counting and prolonging the service life of the device. At the same time, the above-mentioned buffering force can also prevent the internal parts of the feeler rod and precision instruments such as counters from being vibrated and impacted, thereby maintaining the counting accuracy of the feeler rod. It is worth mentioning that the rubber force brought by the buffering rubber pad can increase the friction between the feeler rod and the tree during counting, thereby preventing the operator from hitting the tree due to slipping of the connection between the feeler rod and the tree when applying pressure after the feeler rod touches the tree, thereby further improving the use effect of the device.

[0020] (2) When the operator uses the feeler rod to count trees, if the pressure is too great, the impact force generated will cause impact and vibration to the internal parts and precision instruments of the feeler rod. The buffering force brought by the positioning spring and the auxiliary spring, as well as the buffer zone between the air-permeable round block and the pressure round plate, can convert the kinetic energy generated by pressing into potential energy, so that the buffer zone and the above-mentioned buffering force can store the above-mentioned energy. As the pressing force gradually decreases, the positioning spring and the auxiliary spring in the buffer state gradually reset, and the stored energy is gradually released, thereby playing a buffering role to protect the feeler rod, the counter and the internal precision instruments, etc., to avoid damage caused by excessive force when using the device, thereby improving the service life of the device and the use effect of the device, thereby avoiding the counting accuracy being affected. It is worth mentioning that when the pressure round plate is moving, it is limited to move in the limit slide groove and the limit slide column through the limit slider, so as to limit the movement of the pressure round plate, and avoid dislocation and other phenomena that cause the movement of the feeler rod to be dislocated;

[0021] (3) The two bent square rods move in the same direction, so that the two locking rings move toward the direction of the protective block, so that the locking ring located at the middle position between the end point of the touch rod and the side of the protective block close to the touch rod moves toward the direction of the protective block, so that the distance between the two is gradually reduced until they are in contact. At this time, a locking ring located in the buffer cavity contacts the moving pressure circular plate, thereby limiting the movement of the protection block and supporting the protection block at the same time, preventing the protection block from exceeding the moving distance when moving and causing collision with the touch rod and causing damage, thereby improving the service life of the device and reducing the limitations of the device when in use; the friction between the locking ring and the pressure circular plate and the protective block when in contact is increased by the provided rubber ring pad, thereby preventing slipping and other dislocation phenomena caused by excessive force during contact;

[0022] (4) The moving pressing block drives the marking block to move in the direction of the protection block under the action of the pressing slide bar and the pressing spring. When it has come into contact with the tree, the pressure on the touch rod continues. At this moment, the position of the protection block is relatively static, while the marking block gradually approaches the protection block, so that the distance between the two is reduced until the marking block comes into contact with the tree, thereby marking the tree. This avoids the operator from making mistakes in counting when counting a certain number of trees due to a large number of trees. After marking the trees that have been counted, it can avoid repeated marking during the counting process, thereby improving the use effect of the device and the counting efficiency. Accuracy; It is worth mentioning that at this time, the marking block and the protection block are both in contact with the tree. By continuing to apply pressure to the touch rod, the pressing block will move to the upper limit of the pressing slide bar, so that the pressing spring is in a buffering state, thereby increasing the pressure on the marking block, making the contact strength with the tree large enough, and the contact between the two is thorough, avoiding the failure of the marking block to mark the tree due to incomplete contact with the tree or the lack of obviousness leading to inability to correctly identify, thereby improving the use effect of the device. At the same time, the marking methods of the marking block include but are not limited to ink, environmentally friendly paint or colored ribbons, and the specific materials used can be selected according to actual usage.

After receiving the signal, the sensor transmits the signal to the controller, which converts the signal into a counting signal, so that the display content at the counter 3 changes, that is, the current display number is increased by one, thereby completing the counting operation of the tree; but in order to avoid the phenomenon of missing due to incomplete contact between the sensor and the tree and insufficient connection between the two during the counting process, the feeler rod 1 is continued to be moved after the sensor has contacted the tree, so that its end point is fully in contact with the tree to avoid the above phenomenon, which means that the feeler rod 1 itself and the contact force with the tree are increased, so that the feeler rod 1 moves at the upper limit of the auxiliary cylinder 4, so that the buffer rubber pad 7 and the auxiliary spring 8 are both in a buffering state, which is used to increase the contact force between the sensor and the tree, so that the two are in full contact, avoiding omissions during the counting process, and improving the counting accuracy of the device.

[0041] When the touch rod 1 is in the process of counting trees, it will be limited and moved at the auxiliary cylinder 4, thereby driving the pressure circular plate 20 to move, so that it is limited and moved in the buffer cavity 2, so that the gas inside the buffer cavity 2 is squeezed, causing the gas inside the buffer zone to enter the gas storage area through the air-permeable circular block 5, so that the gas in the gas storage area enters the two L-shaped pipes 9 and acts on the pressing cylinder 11, so that it is limited and moved in the L-shaped pipe 9, and then the pressing block 12 on the pressing cylinder 11 moves toward the direction of the protection block 6, so that the pressing block 12 passes through the guide square column 14 provided on the guide plate 13 The upper limit movement of the pressing base plate 10 makes the guide spring 15 in a buffer state, so that when it is reset, it can redirect the gas in the L-shaped pipe 9 to the gas storage area, and drive the pressure circular plate 20 to reset and move, which is used to drive the reset setting of the contact pressure relief mechanism and the pressure absorbing unit to perform the next counting operation, so as to avoid the next counting operation of the device being affected by its failure to reset, thereby reducing the limitation of the device when in use; and the moving pressing block 12 drives the marking block 17 to move under the action of the pressing slide bar 16 and the pressing spring 18, so that it moves toward the direction of the protection block 6, when it has been in contact with the tree After the tree is in contact with the mark block 17, the pressure on the feeler rod 1 is continuously applied.
