Abstract
Description
Technical Field
[0001] The utility model relates to the field of sawing equipment, in particular to an automatic felling chain saw. Background Art
[0002] In the traditional sawing or felling of crops such as trees and bamboo (for the sake of convenience, this article takes bamboo as an example, but the felling objects include but are not limited to bamboo, trees, branches, plastic pipes, straw, reeds and other crops or materials), the human first holds the chain saw tightly and aligns it with the position to be felled, turns on the switch to let the chain saw's knife chain rotate (similar to the rotation of a circular saw blade), and then pushes the knife chain toward the bamboo, pushing it hard in the depth direction, cooperating with the rotation of the knife chain to saw the bamboo (usually sawing bamboo, just like trees, bamboo is not straight up, that is to say, bamboo also has a growth direction, usually growing obliquely in a certain direction, and finally after being sawed off, the bamboo has a tendency to fall to the oblique side, so when actually felling bamboo, it is necessary to saw a section of the oblique side first, and then complete the sawing on the back, so that the bamboo will not press the saw blade to cause the saw to be clamped, and at the same time avoid the bamboo that is sawed halfway to be broken and torn).

[0028] The present invention will be further described in detail below in conjunction with the embodiments. The following embodiments are intended to explain the present invention but the present invention is not limited to the following embodiments.
[0029] Example 1: Figure 1-4 As shown, the automatic felling chain saw is characterized in that it includes a clamping member, a sawing member, a power member No. 1 and a power member No. 2, a sawing transmission member, a clamping and resetting member, a clamping transmission member and a clutch; the power member No. 1 is preferably a motor, i.e., the main motor 6; the power member No. 2 is preferably a motor, i.e., the feed motor 8; the sawing transmission member is preferably a shaft, i.e., the main shaft 11; the clamping transmission member is preferably a reducer 9; the clamping and resetting member is preferably a clamping and resetting spring 14; the clutch 12 has a synchronous wheel, and the clutch 12 transmits a unidirectional motion force, i.e., the synchronous wheel moves only when the main shaft 11 moves counterclockwise, and conversely, when the main shaft 11 moves clockwise, the synchronous wheel does not move due to the action of the clutch. The No. 1 power member is connected to the sawing transmission member, the sawing transmission member is connected to the clutch and the sawing member, the clutch is connected to the clamping transmission member, the clutch is used to transmit unidirectional motion force, the clamping transmission member is connected to the clamping member to drive the clamping member to open, the clamping reset member is connected to the clamping member to drive the clamping member to close, and the No. 2 power member is connected to the sawing member to drive the sawing member to rotate.
[0030] Preferably, a sawing reset member is included, and the sawing reset member is preferably a sawing reset spring 13, and the sawing reset member is connected to the sawing member to drive the sawing member to return to its original position.
[0031] Preferably, it includes a clamping connector and a sawing connector, the clamping connector and the sawing connector are preferably steel wire ropes, one end of the clamping connector is connected to the through hole at the end of the clamping connector and the other end is connected to and wound around the shaft of the reducer 9, one end of the sawing connector is connected to the through hole at the end of the chain saw support plate 212 and the other end is connected to and wound around the shaft of the feed motor 8. For sawing parts, the small holes at the tail of the left and right chain saw support plates 212 are respectively wound with wire ropes and the shaft ends of the feed motor 8. When the feed motor 8 rotates clockwise, the wire rope on the right will be rolled up, thereby pulling the left chain saw support plate 212 to the right, which is similar to the rotational movement of shearing, forming a saw blade cutting in the right direction; similarly, when the feed motor 8 rotates counterclockwise, it pulls the right chain saw support plate 212 to the left, forming a saw blade cutting in the left direction; the function of the sawing reset spring 13 is that when the feed motor 8 pulls and rolls up the wire rope on one side, the wire rope on the other side is loosened and released, and the released rope is pulled back by the sawing reset spring 13, the purpose of which is to drive the return of the chain saw support plate 212 on the other side. For the clamping part, when the claws need to be opened, the clamping power at this time is through the counterclockwise rotation of the main motor 6, and the main shaft 11 is linked with the belt 10 to drive the reducer 9 to move. The steel wire ropes on both sides of the reducer 9 shaft are wound in the same direction, and will be tightened and rolled up synchronously, thereby overcoming the restoring force of the clamping reset spring 14, and pulling the claws on the left and right sides together to open. When the claws are opened to a suitable angle and placed on the bamboo, the motor button is released, the motor power disappears, and the claws are pulled in the closing direction under the action of the clamping reset spring 14, thereby holding the bamboo to form a clamp. The purpose of setting the feed motor 8 to rotate clockwise and counterclockwise is to correspond to the oblique growth direction of the bamboo. For example, if the human eye judges that the bamboo has a tendency to tilt to the left, then the feed motor 8 rotates clockwise to cut the left side of the bamboo to a certain depth. After it is in place, the sensor is sensed, the motor is stopped, and the chain saw support plate 212 returns to the bottom; after it is in place, the sensor is sensed, and the feed motor 8 starts to rotate counterclockwise, thereby driving the right side to cut until it stops after the set position. This is a complete cycle.
[0032] Preferably, the sawing member includes a chain saw 211 , a chain saw support plate 212 and a bearing 213 . The chain saw 211 is mounted on the chain saw support plate 212 . The chain saw support plate 212 is connected to the main shaft 11 through the bearing 213 . The main shaft 11 is coaxially connected to the clutch 12 .
[0033] Preferably, it includes a casing 1, a battery 5 and a handle 4, the handle 4 and the battery 5 are installed on the casing 1, the clamping member 3 is arranged at the bottom of the casing 1, the sawing member 2 is arranged above the clamping member 3, the main motor 6, the controller 7, the feed motor 8 and the reducer 9 are arranged above the sawing member 2, and the controller 7 has a control chip inside, which can control the operation of all electrical components in the casing 1.
