The sawing is convenient and the power consumption is low. Less, high sawing efficiency. Reasonable and effective use of forest residues is an important link in the realization of cogeneration of heat and power. This machine is targeted. Ordinary sawing machines have the disadvantage of not being able to operate in the forest. This machine is specially used to process forest branches with a diameter of 30mm to 80mm. The whole machine is composed of three parts: biaxial linkage structure, feeding and dialing structure and motion transmission structure. The working process is: the motor transmits the power to the high-speed pulley 11 through the belt, and then transmits the high-speed rotation to the left saw blade shaft 6 and the right saw blade shaft 17, driving the saw blade to saw at high speed; the motor transmits the rotation to the revolution feeder through the reducer The pulley 24 drives the central shaft 12 to rotate, and the revolving frame 4 drives the left saw blade shaft 6 and the right saw blade shaft 17 to revolutionize to complete the feed motion.

Description

Double-station forest branch sawing machine

Technical field

The utility model relates to a carpentry saw section machine mechanism, which can cut forest branches into thin round wood chips. the

Background technique

In recent years, with the rapid development of the national economy, the demand for energy is increasing day by day. Traditional energy sources such as coal, crude oil, and natural gas can no longer meet the needs of human beings. Power generation has gradually become a way to use energy in forest areas, and it has received more and more attention from the country! At present, in order to improve the sawing efficiency, the saw segment machines in the woodworking machinery industry mostly use multi-saw segment saw machines, which differ greatly in terms of technical characteristics, structural characteristics and production quality. Saw segment machines, the European point of view advocates the continued use of dual-spindle machines and single-spindle machines with thick saw blades. In terms of technology, structure, effect and quality, it is not suitable for sawing and cutting branches in the forest. The design is a multi-axis segment sawing machine specially designed for sawing branches in forests. the

Utility model content

The utility model is a double-station forest branch sawing machine, which is used for sawing forest branches. It is easy to operate, simple in structure and high in processing efficiency. The whole equipment is composed of three parts: revolution structure, rotation structure and feeding structure. The technical solution adopted by the utility model is to adopt a double-axis linkage structure. The autorotation structure is composed of multiple saw blade shafts. The autorotation structure is located around the central axis. It is connected with the revolution frame and the intermediate shaft. The feed pulley is transmitted to the intermediate shaft to rotate, so that the two saw blade shafts revolve around the central axis; the motor transmits the sawing power to the left saw blade shaft, the right saw blade shaft, the left saw blade shaft, and the right saw blade shaft through the high-speed pulley Drive the saw blade to rotate at high speed respectively. The left and right stations respectively have a feeding structure to feed materials at the same time. The feeding structure is composed of a barrel, a material clip and a frame part. the

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is described in further detail:

The branch saw machine in the forest consists of three parts: feeding structure, revolution structure and rotation structure. The feeding structure is composed of a material barrel 1, a material clip 20 and a frame part and the like. The revolution structure is mainly composed of a central shaft 12, a high-speed pulley 11, a belt 10, a belt 14, a revolution frame 4, a bearing 13, a shifting chuck 21, a shifting rod 22, a rib plate 23, a revolution feed pulley 24 and a frame part, etc. composition. The rotation structure is mainly composed of saw blade 2, saw blade 19, saw blade seat 18, saw blade shaft support frame 3, bearing 5, left saw blade shaft 6, bearing cover 7, belt pulley 8, shaft end retaining ring 9, and fixing screw 15 , Bearing cover 16, right saw blade shaft 17 and frame part etc. are formed. the

The following is an introduction to the general structure and functions of the machine:

1. The basic structure of two-axis linkage: This is a linkage mechanism integrating revolution and rotation. The rotation is a high-speed sawing movement, and the revolution is a low-speed feed movement. Including central shaft 12, high-speed pulley 11, belt 10, belt 14, revolving frame 4, bearing 13, shifting clip cylinder 21, shifting rod 22, rib plate 23, revolving feed pulley 24, etc. The revolution movement is that the motor transmits the feed power through the revolution feed pulley 24 to the central shaft 12 to rotate through the deceleration, and the central shaft 12 drives the revolution frame 4 to rotate through the keyway connection, and the left saw blade shaft 6 and the right saw blade shaft of the saw segment machine 17 is connected by the revolution frame 4 and the intermediate shaft 12, and the revolution frame 4 transmits the rotation to the saw blade shaft support frame 3 again, so that the left saw blade shaft 6 and the right saw blade shaft 17 rotate around the center shaft 12 in a circle. The rotation motion is that the motor transmits the sawing power to the left saw blade shaft 6 and the right saw blade shaft 17 via the high-speed belt pulley 11, and then transmits the power to the saw blade 2 and the saw blade 19 to rotate to realize sawing. the

2. Feeding and dialing structure: powered by revolution. It includes material cylinder 1, material clip 20, dial clamp cylinder 21, material dial rod 22, rib plate 23 and so on. Within one revolution, the material clamp 20 is first pushed aside by the dial clamp cylinder 21, and the wood falls to the designated position under its own gravity, and is in a state to be processed, and the material clamp 20 is re-clamped. Saw blade 2, saw blade 19 revolutions of high-speed rotation forward to processing position, and sawing wood, after sawing, shifting bar 22 transfers the wood chip that processing has finished to discharge bin. the

3. Motion transmission structure: including rotation motion for high-speed sawing and revolution motion for low-speed feed. The self-rotating structure is composed of a plurality of saw blade shafts, and the self-rotating structure is located around the central axis (12). The rotation motion is transmitted by the high-speed belt pulley 11 to the left saw blade shaft 6 and the right saw blade shaft 17 to drive the saw blades to cut at high speed; the revolution motion is driven by the revolution feed pulley 24 to drive the central shaft 12 to rotate, and then through the revolution frame 4 Drive left saw blade axle 6, right saw blade axle 17 revolutions. the

4. The main technical parameters of the sawing machine for branches in the forest: the circular saw blade diameter of the sawing machine for branches in the forest is Φ350mm, the rotation speed of the saw shaft is 3410±2%r/min, the revolution speed of the central axis is 4.8±3%r/min, The main drive motor model is Y112M-2, the overall dimensions of the machine are 1170x1150x1135mm, and the net weight is 530kg. the
