Description

Javelin is made to trees

Technical Field

The invention relates to the field of tree marking, in particular to a tree marking gun.

Background

To date, the traditional method of numbering trees in a fixed plot that is above the gauge size step is still a branding method, where the number printed by the aluminum spleen is hung 1.3m from the ground of the trunk and marked with red lead oil at 1.3 m. This traditional method of identifying trees has a number of problems in actual field work:

1. the aluminum plate has high manufacturing cost and is easy to be damaged by people, so that the storage time of the aluminum plate is limited. The identification of the identified trees in the sample plot is not facilitated during the reexamination;

2. after the aluminum plate is manufactured, the aluminum plate is hung on each tree manually, and a large amount of labor and time are consumed;

3. some trees need to be punched, inserted with nails and hung, and the hanging mode has great influence on the growth of the trees.

4. Because the four corners of the aluminum plate are sharp, field workers can scratch fingers easily when hanging the plate or picking and recycling the plate.

Therefore, numbering trees in a sample plot by using a traditional listing mode in forest resource investigation brings much trouble to the work of field investigators, increases errors in forest resource review, and increases investigation cost. The invention realizes the numbering of trees in the sample plot quickly and efficiently by utilizing the pressurizing device, the digital model shoe sheet, the driving wheel, the digital transmission gear and other parts. The method simplifies field workload, the paint is marked by a serial number model formed by a digital plectrum and sprayed by a spray head, the storage time is long, the work flow is simplified, the workload is reduced, the speed of forest marking during forest resource investigation is improved, and comparison is performed when forest resources are conveniently rechecked.

The second disc gear 505 is a one-way ratchet structure, which is a prior art and will not be described herein again (refer to fig. 5), an inner wheel of the second disc gear 505 is fixedly connected to a lower end of the transmission wheel at the lowermost layer, the horizontal saw teeth and the first disc gear can only drive the second disc gear to rotate in the forward rotation direction of the digital model crawler belt, and when the horizontal saw teeth and the first disc gear move in the reverse direction, the second disc gear idles, so that the digital model crawler belt only rotates in the forward rotation direction and does not rotate in the reverse rotation direction.

A third disc gear 506 is fixed at the upper end of one of the driving wheels 502 at the lowest layer, the driving wheel at the lowest layer rotates to drive the third disc gear to rotate, a fourth disc gear 507 and a fifth disc gear 508 which are coaxial are rotatably installed on the gun body 1, a sixth disc gear 509 is fixed at the lower end of one of the driving wheels 502 at the middle layer, the third disc gear 506 is meshed with the fourth disc gear 507, the third disc gear 506 drives the fourth disc gear 507 to rotate, the fifth disc gear 508 rotates because the fourth disc gear 507 and the fifth disc gear 508 are coaxial, the fifth disc gear 508 is meshed with the sixth disc gear 509, the fifth disc gear 508 drives the sixth disc gear 509 to rotate, the number of teeth of the third disc gear 506, the fourth disc gear 507 and the sixth disc gear 509 is ten, and the number of teeth of the fifth disc gear 508 is one, the third disk gear 506 and the fourth disk gear 507 drive the fifth disk gear 508 to rotate ten grids (one circle), and the fifth disk gear 508 drives the sixth disk gear 509 to rotate one grid. A seventh disc gear 510 is fixed on the upper end of one of the middle transmission wheels 502 to make the seventh disc gear rotate together with the middle transmission wheel, an eighth disc gear 511 and a ninth disc gear 512 which are coaxial are rotatably installed on the gun body 1, a tenth disc gear 513 is fixed on the lower end of one of the uppermost transmission wheels 502, the seventh disc gear 510 is meshed with the eighth disc gear 511, the ninth disc gear 512 is meshed with the tenth disc gear 513, so that the tenth disc gear rotates together when the seventh disc gear rotates. The number of teeth of the seventh disc gear 510, the eighth disc gear 511 and the tenth disc gear 513 is ten, and the number of teeth of the ninth disc gear 512 is one, so that the transmission wheel at the middle layer rotates for one circle, and the transmission wheel at the uppermost layer can rotate for one grid. I.e., the number 000-999 from top to bottom is realized for 1000 numbers.

The sixth disc gear 509 and the tenth disc gear 513 are also of a one-way ratchet structure, inner wheels of the sixth disc gear 509 and the tenth disc gear 513 are fixedly connected with lower ends of the middle-layer driving wheel 502 and the upper-layer driving wheel 502 respectively, and a connection structure of the inner wheels is the same as a connection structure of the second disc gear 505 and the lower end of the lowermost driving wheel, which is not described herein again. Because the second disc gear, the sixth disc gear and the tenth disc gear are in the inner and outer wheel clamping state only when the digital model crawler belts on the upper layer, the middle layer and the lower layer rotate forwards, the second disc gear, the sixth disc gear and the tenth disc gear are in idle rotation when the digital model crawler belts on the upper layer, the middle layer and the lower layer rotate backwards, and only the digital model crawler belts need to be manually rotated backwards to reach the designated position when specific numbers need to be acquired. Furthermore, the third disc gear 506 and the seventh disc gear 510 are also in a one-way ratchet structure, inner wheels of the third disc gear 506 and the seventh disc gear 510 are respectively and fixedly connected with upper ends of the lower layer driving wheel 502 and the middle layer driving wheel 502, and a connection structure thereof is the same as a connection structure of the second disc gear 505 and a connection structure of a lower end of the lowermost layer driving wheel, and details are not repeated here. The third disk gear 506 and the seventh disk gear 510 are of a one-way ratchet structure, so that four intermediate transmission gears, namely the fourth disk gear 507, the fifth disk gear 508, the eighth disk gear 511 and the ninth disk gear 512, are kept from rotating when the digital model crawler rotates reversely.

When the digital model crawler is used, the pressing rod is pressed, the paint and water mixing box moves backwards, the paint and water mixing box drives the transmission wheel at the lowermost layer to rotate by one grid, so that the digital model crawler at the lowermost layer rotates together to display the next number; meanwhile, the paint water mixing box drives the opening and closing device to be opened, and paint and water enter the paint water mixing box to be mixed; the pressure rod triggers a gas valve switch 201 of the gas supply cylinder 2, so that high-pressure gas enters the paint-water mixing box to spray paint and water from the branch end; the paint-water mixture is subjected to hollow-out numbers of the digital model crawler belt, and numbers are displayed on the trees; the numbers at the lowest layer change for one hundred times, the numbers at the middle layer change for ten times, and the numbers at the top layer change for one time, so that the automatic rolling of the numbers of ten and hundred is realized.

The method is extremely convenient and fast, and greatly reduces the workload for workers numbering trees in the sample plot in forest resource investigation; for forestry departments, the manufacturing cost of the numbered tree cards is reduced; for ecological environment, the damage to the trees caused by punching and hanging the cards is avoided, and the normal growth of the trees is prevented from being influenced.
