The 4UQ-165 potato harvester is a large and medium-sized mechanical equipment widely used in potato harvesting, developed by Hisense Tiancheng in close cooperation with research institutes such as the National Potato Engineering Technology Research Center and Shandong University of Technology. It can achieve adjustable row spacing, separate potatoes from soil, separate potato seedlings, and lay potato chunks together. It has advanced characteristics such as high potato exposure rate, low damage rate, and low skin breakage rate, and its technical level is significantly better than similar products in the market.

1. Width limited disc knife:Mainly used to cut open the surface along both sides of the potato ridge along with weeds, facilitating the excavation of parts and preventing the entanglement and blockage of stems and weeds on both sides of the machine.

2. Excavate components:Used to dig potatoes along with the entire width of the soil, while the secondary shovel can prevent hard objects such as stones from damaging the conveyor chain.

3. Suppression depth limiting device:It mainly consists of a copying depth limiting wheel, a bracket, and an adjusting mechanism. The copying depth limiting wheel is used to control and adjust the excavation depth of the digging shovel, and make the potatoes and soil loose, which is conducive to the later separation of potatoes and soil.

4. Grid type conveying separation screen and shaking wheel combination:The conveyor belt is driven by a driving wheel, which is made of rubber teeth and meshes well with the steel grating. It has light wear and a long service life; This type of conveying separation screen is reliable and has less damage to potatoes. The shaking wheel can shake and transport the separation screen, improving the separation ability between potatoes and soil.

5. Potato seedling separation mechanism:It is mainly composed of stem rollers and pressure barriers, which separate potato stems and potatoes and have the function of removing potato stems and weeds.

6. Seedling side output mechanism:It mainly consists of a conveyor frame, a conveyor belt, and a power transmission mechanism. The potato stems, leaves, and weeds sent by the potato seedling separation mechanism and the tail sieve are transported to the side ridge ditch and laid on the ground.

7. Tail sieve:After passing through the conveying separation screen and the potato seedling separation mechanism, the potatoes fall onto the tail screen. Through reverse operation, the weeds with light density are sent to the top and fall onto the output belt on the side of the seedling vine, and transported to the side. The potatoes with heavy density are regularly laid on the ground through the potato shaping and laying device.

8. Potato shaping device:By adjusting the potato collecting baffle and laying potatoes on the compacted ground, this device greatly improves the potato yield for later picking.

9. Overload clutch transmission shaft:Excessive load can cause the transmission shaft to slip, which is used to protect the equipment from injury.

10. Efficient Potato Soil Separation Technology:Developing a replica depth limiting wheel, vibrating mesh conveyor screen, and reverse rubber claw grid, which enables the harvester to not only adjust the harvesting depth, but also loosen the potato soil, facilitating the separation of potato soil and greatly improving the potato soil separation effect.

11. Potato seedling separation technology:Developing a floating soil cutting disc and a rotating rubber wheel setting not only achieves good cutting effect on potato seedlings, but also minimizes the damage of hard objects such as stones in the soil to the soil cutting disc, completely solving the problem of potato seedlings not being separated and damaging potatoes.

12. Block collection strip laying technology:Developing strip laying technology, designing strip laying devices, and regularly laying harvested potatoes on the top of ridges, which is conducive to later grading and bagging, greatly improving production efficiency.
