The tractor's PTO drive shaft drives the pump transmission case, which is connected to the gear pump, driving the gear pump at high speed. This pumps hydraulic oil from the tank into the solenoid valve group. When the remote control is clicked, the receiver receives the signal, which is transmitted through the solenoid valve group to complete the various cylinder movements.

[0021] Installation steps:

[0022] The first step is to install the mechanical components: first, lay the outer frame 16 flat on the ground, and insert the middle moving frame 17 into the outer frame 16 to the bottom through the composite roller bearings on both sides; pre-install the support plate 26 in the inner frame 25, and insert the two together into the middle moving frame 17. After completion, fix the bracket 18 to the middle moving frame 17 with bolts and nuts. Iron wheel 19 is fixed to the bracket 18 by a pin shaft, and there are 2 of them. Iron wheel 28 is fixed to the top of the inner frame 25, and there are 2 of them. Long chain 24, 2 in number, passes through iron wheel 19 connected to the bracket 18, and one end is fixed to the connecting seat of the inner frame 25, and the other end is fixed to the chain seat of the outer frame 16; short chain 20, 2 in number, passes through iron wheel 2 28 assembled on the top of the inner frame 25, and one end is fixed to the bracket 18, and the other end is fixed to the chain seat of the support plate 26; after the above assembly is completed, the assembly will be erected and supported by the legs; 2 nylon guide rails 21 will be installed in the upper and lower beams of the side shift connecting rod 23 by bolts and nuts, and then installed horizontally on the support plate 26, and the left fork 22 and the right fork 27 will be installed at the bottom of the side shift connecting rod 23 by fork pins, and safety pins will be installed on both sides. At this point, the assembly of the structural parts is basically completed.

[0023] Second, install the hydraulic components: First, install the lifting cylinders 5 on both sides of the outer frame 16. The side shift cylinder 4 is connected to the support plate 26 with bolts and nuts. The swing cylinder 10 is mounted on the cylinder connecting plate of the outer frame 16 via a pin. The valve body support plate 7 is mounted on the L-shaped plate of the outer frame 16. The solenoid valve assembly 13 and the wireless receiver 6 are installed on the valve body support plate 7. Later, the return oil filter assembly 9 will be pre-installed on the oil tank 8, and both will be installed together on the outer frame 16. The gear pump 11, oil pump transmission case 12, and gear case stop plate 14 are assembled separately and not installed on the main machine. All hydraulic system pipes and connectors are installed. Once this is complete, the protective net 15 is bolted to the top of the outer frame 16. This completes the assembly process.

[0024] After assembly, the whole structure is connected to the tractor through a three-point suspension, and the tractor is started. The tractor PTO drive shaft drives the oil pump transmission box to work. The oil pump transmission box is connected to the gear pump, driving the gear pump to run at high speed. The hydraulic oil in the tank is input into the solenoid valve group. Click the remote control to transmit the signal. The receiver receives the signal and completes various actions of the oil cylinder through the solenoid valve group to complete the operation. The operation actions include lifting, side shifting, and swinging.

[0025] The lifting action is as follows: the lifting cylinders 5 on both sides push upward, driving the middle moving frame 17 upward synchronously, one end of the long chain 24 is fastened to the chain seat of the outer frame 16, and the other end is connected to the inner frame 25, and the inner frame 25 moves upward; one end of the short chain 20 is fixedly connected to the bracket 18, and the other end is fixed to the chain seat on the support plate 26. The upward movement of the support plate 26 drives the fork tine to move upward. The ratio of the cylinder stroke to the inner frame 25 stroke is 1:2 / the ratio of the cylinder stroke to the fork tine stroke is 1:3.

[0026] The side shift action is as follows: one end of the side shift cylinder pushes out and contacts the block on the side shift weldment, driving the fork tines to move sideways as a whole, and the forklift can move left and right.

[0027] The forward and backward swing: one end of the swing cylinder is connected to the forklift, and the other end is connected to the tractor. The cylinder is extended and retracted to drive the forklift to tilt forward and backward.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
