[0002] The production of pine resin in China has developed rapidly, and the production technology has improved rapidly. However, so far, the main source of pine resin is the large number of cheap laborers in mountainous rural areas. Each pine tree needs a worker to cut a new cut below the original cut every 1-3 days. The process of collecting resin is long, labor-intensive, low in productivity, and hard work. Moreover, many resin farmers do not use scientific cutting methods when collecting resin, which causes great damage to the pine trees and seriously affects the sustainability of collecting resin.

[0003] At the same time, the existing cutting device is fixed on the working surface of the tree trunk with nails, so only one pine tree can be cut in one pine resin collection cycle, and a device needs to be installed on each tree, which increases the collection cost. And because the device is fixed on the tree trunk with nails, it damages the pine xylem, which is not conducive to the sustainability of pine tree resin collection.

[0004] Therefore, there is an urgent need for a rosin cutting device that can replace manual resin collection surface cutting and can cut many pine trees in one working day at the same time, has low cutting cost and high work efficiency, and its installation method can not cause damage to the tree trunk.

DETAILED DESCRIPTION

[0023] Example 1

[0024] An automatic rosin cutting device comprises a base 10, a bottom plate 20, a support frame 30 and a support arm 70;

[0025] The base 10 is used for fixed support of the cutting device; the bottom plate 20 is arranged on the base 10 so as to reciprocate along a straight line;

[0026] The support frame 30 includes a support rod 31 and a column 32; the support rod 31 is fixedly connected to the base plate 20 at an inclination angle. In the present embodiment, the inclination angle between the support rod 31 and the base plate 20 is 30°-60°, preferably 45°; one end of the column 32 is fixed to the base plate 20, and the other end is fixedly connected to the end of the support rod 30 away from the inclination apex; a driven wheel 120 is provided at one end of the inclination apex of the support rod 30, and a driving wheel 50 is provided at the other end; one end of the support arm 70 is hinged to the driving wheel end of the support frame 30, and the other end is provided with an idler wheel 80.

[0027] A driving chain 100 is arranged between the driving wheel 50, the driven wheel 120 and the idler wheel 80 to make them rotate in the same direction. In this embodiment, the plane constructed by the chain 100 is arranged parallel to the axial center line of the support rod 70; an elastic component is arranged between the support arm 70 and the support rod 31, for maintaining a set angle between the support arm 70 and the support rod 31; in this example, the elastic component is a gas spring, preferably a nitrogen spring 60.

[0028] A tool 110 is arranged on the chain between the driven wheel 120 and the idler wheel 80. In this embodiment, the tool is arranged on two groups of chain units of the chain 100 to reduce the unevenness of the cutting force during the cutting of the tree trunk; a baffle 90 that can be deformed synchronously with the chain between the driven wheel 120 and the idler wheel 80 is arranged to limit the cutting depth of the tool 110; in this embodiment, the baffle 90 is a high-quality spring steel plate with a thickness of 1 mm, and its two ends are arc structures arranged corresponding to the driven wheel 120 and the idler wheel 80 and are respectively fixedly connected to the driven wheel 120 end of the support rod 31 and the idler wheel 80 end of the support arm 70; an opening 91 is arranged on the baffle 90 corresponding to the tool moving route to limit the cutting length of the tree trunk; the exposed length of the tool 110 after passing through the corresponding opening 91 on the baffle 90 is 1-3 mm, preferably 2 mm.

[0029] A driving device is arranged between the driving wheel 50 and the support rod 31. In the present embodiment, the driving device comprises a motor mounting base 42 and a driving motor 41. The motor mounting base 42 is fixedly connected to the support rod 31, and the driving wheel 50 is fixedly connected to the output shaft of the driving motor 41. The driving motor 41 is preferably a stepping motor. The working stroke of the stepping motor is less than or equal to the length of the opening 91 on the baffle 90, and it can perform reciprocating motion.

[0030] An electric slide 13 is arranged between the bottom plate 20 and the base 10 for relative sliding between the bottom plate 20 and the base 10 ; the electric slide 13 includes a slider and a slide seat, the bottom plate 20 is arranged on the upper surface of the slider, and the slide seat is arranged on the top of the base 10 .

[0031] In this embodiment, an electric control rotating platform 11 is further provided between the bottom plate 20 and the slide base of the electric slide 13, which is used to adjust the cutting angle between the bottom plate 20 and the tree trunk, that is, when the tree trunk becomes smaller, the corresponding center angle becomes smaller, and at this time, the bottom plate 20 is rotated by the electric control rotating platform 11 to make up the center angle (see FIG. Figure 3 The electric slide 13 and the electric control rotating table 11 are fixedly installed by connecting the connecting plate 12 .

[0032] The base 20 is provided with a lifting platform 14 for adjusting the resin cutting height.

[0033] A contact limit sensor is provided on the side of the bottom plate 20 away from the driven wheel 120 , and the cutter 110 stops feeding when the contact limit sensor contacts the tree trunk.

[0034] In this embodiment, a control module is also provided, which is signal-connected to the contact limit sensor, the drive motor 41, the electric slide 13, and the electric-controlled rotating table 11, and is used to control the above-mentioned electrical components.

[0035] The working principle of this embodiment:

[0036] The tree trunk is attached to the transmission chain device with an idler wheel 80 to initially form a cutting track. The cutter 110 is mounted on the chain 100. At the same time, the baffle 90 and the chain between the driven wheel 120 and the idler wheel 80 are synchronously deformed to limit the cutting depth of the cutter 100. Due to structural limitations, it is impossible to obtain cutting tracks with equal central angles on tree trunks of different diameters. It is necessary to add a rotational degree of freedom to the overall mechanism to make up for the missing angle. Figure 2 At the beginning, the base plate 20 is horizontally attached to the tree trunk, and the support rod 31 on the support frame 30 is connected to the support arm 70 by a hinge. At the same time, a nitrogen spring 60 is installed between the support rod 31 and the support arm 70. The center of the driven wheel 120 is always on the same vertical line as the center of the tree. During the fitting process, the chain 100 between the driven wheel 120 and the idler wheel 80 bends when it hits the tree trunk. However, due to the presence of the nitrogen spring 60, the angle between the support rod 31 and the support arm 70 is always in a trend of increasing, so that the chain 100 is always taut and slowly fits on the tree trunk. When the driven wheel 120 contacts the tree trunk, the feeding stops. When the diameter of the tree trunk changes, the center angle corresponding to the chain 100 that fits the tree trunk will change. In order to obtain the same center angle, the overall structure is rotated around the center point of the driven wheel 120 so that the corresponding center angles on trunks of different diameters are the same, such as Figure 3 .

[0037] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
