Abstract

PURPOSE:To obtain the titled machine which can be freely attached to or detached from a tractor, by attaching a three point attaching metal fitting to a longitudinal frame on a body frame, pivoting a three point link supporting shaft, and providing a linking part on a PTO. CONSTITUTION:Right and left lower links which are provided at the rear part of the tractor, are pivoted to attaching metal fittings by pins. A supporting shaft 31 is connected to an upper link. Then, a PTO shaft of the tractor is linked to a main shaft 5 of a speed change gear 4. In this way, the machine is used. The tractor is moved to a lumber collecting yard. The lumber collecting work is performed by trnsmitting a rotary force of the PTO shaft to a winch 3 by way of the speed change gear 4. When the operating lever of the speed change gear 4 is shifted to the forward rotation side, a secondary shaft is rotated in the forward direction and the rotary shaft of the winch 3 is also rotated in the forward direction. When a handle shaft 10 is located at the position in the Figure, the clutch of the winch 3 is shifted to an OFF position, and the linkage between the rotary shaft and a wire drum 26 is separated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lumber collecting machine that is used by being attached to the rear of a tractor.

Conventionally, when collecting logs from felled logs, a cable crane is used as a large-scale device, and a track-type lumber truck is used for small-scale collection. However, even if a tracked timber collection vehicle is used, it has disadvantages such as being expensive because it is a special vehicle. This is a device designed to perform lumber work, and is characterized by being able to be used in narrow spaces where tractors pass, being inexpensive, and allowing the tractor to also perform lumber collection work. A vertical frame 2 is erected at the front position of an O-underframe 1, a nigra reach 3 is installed on the rear upper surface of the underframe 1, and a gear shifter is installed at the center position of the vertical frame 2. The machine 4 is installed, the main shaft 5 is projected forward □, and the countershaft 6 that projects to the side of the transmission 4 and the drive gear 7 of the winch 3 are interlocked via the intermediate shaft 8, and the upper left side of the vertical frame 2 is connected. A hinge 9 is provided at the position, a central position of the handle shaft 10 is pivotally connected to the hinge 9,
A clutch lever 11 (
7) Connect the shaft piece 12 protruding laterally to the lower end of the handle shaft 10 with a connecting rod 13, and make the hanging frame 14 protrude toward the back from the center position of the upper surface of the vertical frame 2, A bearing 1 is installed on the lower surface of the reinforcing rods 15, 151 connected to the hanging frame 14 and the vertical frame 2.
6, 16' are attached to pivotally support a horizontal shaft 17, an arm rod 18 is provided at one end of the horizontal shaft 17 to protrude obliquely upward in the front, one end of a connecting rod 19 is connected to the arm rod 18, and a clutch is connected. The connecting rod 21 with an idle groove 20 connected to the upper end of the lever 11 and the connecting rod 19 are loosely connected by the idle groove 20, and a brake lever 23 is provided protruding from the upper end of the hand brake 22 on the right side of the winch 3. The other end of the connecting rod 24, which has one end connected to the upper end, is connected to the arm rod 1 from the horizontal axis 17.
A wire is connected to an arm rod 18 degrees projecting diagonally downward in symmetry with 8 when viewed from the side, has a constant slip jji 25, 25 degrees suspended from the lower surface of the tip of the hanging frame 14, and is wound around the wire drum 26 of the winch 3. A rope 27 is passed through and a hook 28 is fixed at the tip, the C1 rods 29 are fixed on both front and rear sides of the underframe 1, and three-point link mounting brackets 30 and 30' are attached to the lower positions on both sides of the vertical frame 2. A three-point link support shaft 31 is pivotally attached to the upper center position of the vertical frame 2 to constitute a timber collecting machine 32 projecting in the front direction. In the figure, 33 is a tractor, and 34 [
) Largtarlower link, 35 indicates log.

Next, the effects of the present invention will be explained with reference to embodiment figures.

The lumber collecting machine 32fl of the present invention,) Left and right lower links 34.34i mounting brackets 30.3 provided at the rear of the rafter 33
0' with a pin, and is connected to the upper IJ link (5 support 111131t), and is used by connecting to the main shaft 5 of the tractor's PTO shaft EF gear 4. The rotary force of the P and TO shafts is transmitted to the winch 3 via the transmission 4 to perform timber collection work.

In the transmission 4, when an operating lever (not shown) on the top surface is switched to the forward rotation side, the subshaft 6 rotates in the forward direction, and the rotating shaft of the winch 3 also rotates in the forward direction. When the winch 3 is in the position shown in FIG. 2, the clutch of the winch 3 is OFF, and the rotating shaft and the wire drum 26 are disconnected from each other. Therefore, the wire rope 27 is pulled out while the wire drum 26 is idling, the wire rope 27 is wound around the felled log, and the wire rope 27 is secured with the seven hooks 28.The tractor driver then presses the handle shaft 10 in the direction of arrow A. Then, the clutch lever 11 rotates forward and the wire drum 2
Clutch 6 is turned on and off, and the wire drum 26 rotates forward with the rotating shaft, winding up the wire rope 27 and pulling the raw wood toward the lumber collecting machine 32.
When the tractor 33 is running with the clutch lever 11 [? is turned OFF, and the wire drum 26 is removed from the rotating shaft.
is disconnected, and the connection lever 21. at the upper end of the clutch lever 11 is disconnected. The horizontal shaft 17 is rotated through the connecting rod 19 and the arm rod 18, and the pre-A-L/bar 23 is rotated through the arm rod 18° and the connecting rod 24.
e The tractor 33 rotates forward to apply brakes to the wire drum 26 and prevent the wire drum 26 from idling.
The logs are towed and moved by running the logs. Since the connecting rod 2.1 at the upper end of the clutch lever 11 is provided with an idle groove 2o, even if the handle shaft 10 is pressed in the direction of arrow A and the clutch lever 11 is rotated forward, the idle groove 2o will not open. Therefore, force is not applied to the connecting rod 19, and the brake lever 2
3 maintains the neutral state as it is. When collecting wood while winding the wire rope 27 around the wire drum 26, the wood collecting machine 32 is lowered and landed by a three-point link,
By inserting and locking the wedge rod 29 of the underframe 1 into the ground, pressure applied to the wood collecting machine 32 can be stopped, and the tractor driver can easily collect wood by operating the handle shaft 1o. It is possible to carry out lumber work, and it can also be towed by a tractor, and it is possible to collect lumber in narrow spaces where the tractor can pass, and it is possible to plan for labor saving in pulling out thinned wood and other lumber collection work, etc. It has various remarkable effects such as
