Specifically, the rubber tapping mechanism 5 is connected with the seat plate in a sliding manner and is connected with the shell 1.

Rubber tapping machine structure of trading, its theory of operation as follows:

as shown in fig. 3, when the motor 2 drives the bevel gear 431 to rotate counterclockwise through the gear (looking from the end of the card member B46 to the shaft sleeve 42), the shaft sleeve 44 slips and is not screwed on the external thread of the driving member 43, the inclined tooth surface of the triangular card tooth a432 slides on the inclined tooth surface of the triangular card slot on the card member a45 in sequence, and simultaneously, under the spring force of the return spring 47, the card member a45 and the card member B46 make a left-right linear reciprocating movement. However, when the triangular latch a432 slides over the inclined tooth surface of the triangular slot, the friction force applied to the clip a45 by the triangular latch a432 is small and is not enough to drive the clip a45 and the clip B46 to drive the rotating shaft 41 to rotate relative to the screw, so that the position of the rotating shaft 41 on the screw is unchanged, and the relative positions of the housing 1 and the tapping mechanism 5 to the screw are unchanged.

When the motor 2 drives the bevel gear 431 to rotate clockwise through the gear, the internal thread on the shaft sleeve 44 is screwed on the external thread on the driving part 43 and gradually moves towards the direction far away from the bevel gear 431, the straight tooth surface of the triangular latch A432 is attached to the straight tooth surface of the triangular latch groove on the latch A45, and the latch A45 and the latch B46 are driven to rotate, so that the rotating shaft 41 is driven to rotate relative to the screw, and the rotating shaft 41, the housing 1 and the tapping mechanism 5 move together along the axial direction of the screw. When the shaft sleeve 44 moves to the right side of the external thread of the driving piece 43, the shaft sleeve 44 starts to slip, the triangular clamping groove on the clamping piece A45 is separated from the triangular clamping tooth A432 on the driving piece 43, the rotating shaft 41, the shell 1 and the tapping mechanism 5 do not move along the axial direction of the screw, and the line changing is completed.

When the motor 2 drives the bevel gear 431 to rotate counterclockwise again through the gear, the internal thread on the shaft sleeve 44 is screwed with the external thread on the driving piece 43, and the shaft sleeve 44 moves leftwards to reset. When the whole body needs to be reset, the upper shell of the shell 1 is removed, the gear on the motor 2 is separated from the bevel gear 431, the locking screw is loosened, the plum blossom-shaped handle at the end part of the screw rod is rotated, the lower shell of the shell 1, the rubber tapping mechanism 5 and the rotating shaft 41 are reset to the initial position, then the upper shell of the shell 1 is installed, and the rubber tapping machine is debugged.

The first embodiment is as follows:

the casing 1 is provided with a traveling gear which is meshed with the helical gear 431, the traveling gear partially extends out of the casing 1, travel switches are arranged on two sides of the casing 1, and the motor 2 is positioned between the two travel switches. The tapping machine comprises a battery, a tapping mechanism 5, a controller and a line changing structure. The rubber tapping mechanism 5 comprises a rubber tapping motor and a rubber tapping tool bit arranged on an output shaft of the rubber tapping motor, the rubber tapping mechanism 5 is arranged on the bottom plate through a lifting mechanism, and the bottom plate is connected with the seat plate in a sliding manner and is connected with the shell 1. The battery is electrically connected with the motor 2, the tapping motor, the controller and the lifting mechanism, and the controller is installed in the shell 1 and is electrically connected with the motor 2, the tapping motor, the travel switch and the lifting mechanism.

As shown in fig. 8, an upper bandage 7 and a lower bandage 9 are bound on the rubber tree, the lower bandage 9 is connected with the upper bandage 7 through a steel pipe 8, the rail 6 surrounds the rubber tree, one end of the rail is connected with the upper bandage 7, and the other end of the rail is connected with the steel pipe 8. A rack is processed on the track 6 at a position corresponding to the walking gear, a seat plate in the tapping machine is in sliding connection with the track 6, and the rack is meshed with the walking gear. Two limiting parts 10 are installed on the rail 6, and the rubber tapping machine is located between the two limiting parts 10.

As shown in fig. 8, the tapping machine is located at the highest working position, after the tapping machine is started, the tapping motor drives the tapping cutter head to rotate, the lifting mechanism drives the tapping motor and the tapping cutter head to move to contact with the rubber tree, and the tapping cutter head cuts into the rubber tree by a certain depth. Meanwhile, the motor 2 drives the bevel gear 431 to rotate counterclockwise through the gear (looking from the end of the clamping piece B46 to the shaft sleeve 42 in fig. 3), the bevel gear 431 drives the walking gear to rotate, and the rubber tapping machine descends along the rail 6 due to the fact that the walking gear is meshed with the rack on the rail 6. When the travel switch on the shell 1 contacts the limiting part 10 close to the lower binding band 9, the lifting mechanism drives the rubber tapping motor and the rubber tapping cutter head to move and be separated from the rubber tree, and the rubber tapping motor stops running.

After the tapping motor stops running, the motor 2 rotates reversely, the bevel gear 431 is driven to rotate clockwise through the gear, and the rotating shaft 41, the shell 1 and the tapping mechanism 5 move upwards for a certain distance along the axial direction of the screw rod to complete line changing. The rubber tapping machine moves upwards along the track 6 until the travel switch on the shell 1 is contacted with the limiting part 10 close to the upper binding band 7, the rubber tapping machine stops running, and one working cycle is completed. And after the tapping machine operates again, a new tapping groove can be cut at the upper side of the original tapping groove.

Cutting a tapping groove on the rubber tree every day, wherein the distance between the tapping grooves is 1.5mm, and the line changing structure of the tapping machine is integrally reset every half year.
