Description

Log cutting loading attachment

Technical Field

The utility model relates to a forestry machinery technical field is a log cutting loading attachment who is used for oil pipe down of being applied to the job site in the pit.

Background

In forestry production process, need use band sawing machine to carry out axial cutting to the log, in the cutting process, the log needs to pass through loading attachment axial feed, before the axial feed, need lay the log earlier on feeding the track, be called the material loading. Currently, the loading method is to push the logs placed on the shelves onto the feeding track one by one manually or mechanically. The disadvantages of this approach are: the existing feeding process is divided into two actions, namely pushing the logs to be processed to the feeding track and moving other logs on the rack, so that the logs gradually approach the feeding track. The feeding mode consumes more manpower compared with the manual operation mode, and the feeding mode causes the feeding equipment to be complex compared with the mechanical operation mode.

An object of the utility model is to provide a log cutting loading attachment to solve the problem that proposes among the above-mentioned background art.

The utility model provides a technical problem adopt following technical scheme to realize: the utility model provides a log cutting and feeding device, which comprises a frame, a base and a feeding track, wherein the frame is arranged on one side of the base, the feeding track is fixed on the top of the base, the log cutting and feeding device also comprises a hydraulic cylinder, a feeding hook and a connecting rod, the cylinder barrel of the hydraulic cylinder is fixedly connected on the base, the upper end of the feeding hook is hinged on the side surface of the feeding track, one end of the connecting rod is hinged on the piston rod of the hydraulic cylinder, and the other end of the connecting rod is hinged in the middle of the feeding hook;

the feeding hook structurally comprises a straight shank part and a hook part, wherein the straight shank part and the hook part are hinged, a rotation limiting plate for limiting the included angle between the straight shank part and the hook part is welded at the lower side of the hook part, and a hinge point between the connecting rod and the feeding hook and a hinge point between the feeding track and the feeding hook are both positioned at the straight shank part;

the frame be the frame construction that the steel pipe welded, the face that is used for supporting the log on the frame is an inclined plane, the least significant end on inclined plane is provided with the log limiting plate.

The cross section of the feeding track is V-shaped, and a roller is arranged on the contact surface of the feeding track and the log. The hydraulic cylinder is a double-acting hydraulic cylinder.

The utility model has the advantages that: the utility model discloses utilize gravity to make the log on the shelf automatically to feeding the track and be close to, then adopt by hydraulic drive's material loading hook will be located the log of lower extreme and lift to make it roll under the action of gravity and fall on feeding the track, compare with prior art, not only saved the manpower, simplified the structure of equipment moreover.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic view of the structure of the rack;

fig. 3 is a schematic structural view of the hook part and the straight shank part after relative rotation.

In the figure: 1-frame, 2-log, 3-bent hook part, 4-straight handle part, 5-feeding track, 6-roller, 7-connecting rod, 8-piston rod, 9-cylinder, 10-base, 11-rotation limiting plate and 12-log limiting plate.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

the present embodiment includes a rack 1, a base 10, and a feeding rail 5, wherein the rack 1 is placed on one side of the base 10, and the feeding rail 5 is fixed on the top of the base 10. The above is a common structure in the prior art, and is not described herein again.

The novel part of the invention also comprises a hydraulic cylinder, a feeding hook and a connecting rod 7, wherein a cylinder barrel 9 of the hydraulic cylinder is fixedly connected on a base 10, the upper end of the feeding hook is hinged on the side surface of the feeding track 5, one end of the connecting rod 7 is hinged on a piston rod 8 of the hydraulic cylinder, and the other end of the connecting rod 7 is hinged in the middle of the feeding hook. Frame 1 be the frame construction that the steel pipe welded, the face that is used for supporting log 2 on the frame 1 is an inclined plane, the least significant end on inclined plane is provided with log limiting plate 12, prevents that log 2 from rolling down. The utility model discloses utilize gravity to make log 2 on the shelf 1 automatic to being close to feeding track 5, then adopt by hydraulic drive's material loading hook will be located log 2 of lower extreme and lift to make it roll under the action of gravity and fall on feeding track 5, compare with prior art, not only saved the manpower, simplified the structure of equipment moreover.

The structure of material loading hook includes straight stalk portion 4 and crotch portion 3, and straight stalk portion 4 links to each other with 3 articulations of crotch portion, and the downside welding of crotch portion 3 has the rotatory limiting plate 11 that is used for restricting the angle that presss from both sides between straight stalk portion 4 and the crotch portion 3. When the loading hook is used for loading, the straight shank part 4 and the hook part 3 are in the position state as shown in figure 1, in this state, the upper end of the rotation limiting plate 11 is abutted against the lower side of the straight shank part 4, so that the position shown in figure 1 is changed into the lower limit position of the hook part 3, and the round log 2 is ensured to be smoothly hooked and lifted. After one feeding, the feeding hook rotates counterclockwise, when the lower side of the hook part 3 contacts the log 2, the hook part 3 starts to bear the rotation moment and rotates clockwise, so that the hook part 3 returns to the lower part of the lowest log 2 on the shelf 1 again to prepare for the next feeding, and the rotated state is as shown in fig. 3. It should be noted that, here, it is necessary to ensure that the hook portion 3 in fig. 3 can smoothly return to the position shown in fig. 1, and for this reason, a torsion spring may be provided at the hinge joint of the straight shank portion 4 and the hook portion 3, and the hook portion 3 may also be reset by its own weight, and when resetting by its own weight, only a sufficient return distance needs to be provided by the hydraulic cylinder.

The hinge point between the connecting rod 7 and the feeding hook and the hinge point between the feeding track 5 and the feeding hook are both positioned on the straight shank part 4.

The cross section of the feeding track 5 is V-shaped, and the contact surface of the feeding track 5 and the log 2 is provided with the roller 6, so that the friction resistance is reduced.

The hydraulic cylinder is a double-acting hydraulic cylinder.
