4YZT-7/8 Self-propelled Maize Harvester

It can be clutched corn chopsticks with different row spacing in 7 and 8 rows, hard wheat chopsticks with 4.57 m cutting pairs and flexible soybean chopsticks with different cutting pairs. Thanks to the world's advanced technology of common axis hammer separating drum, it can simultaneously perform cleaning, grinding, cleaning and separation, and unloading and transportation to corn and other crops. By replacing various hammer drums, separation devices and harvesting bushes, it can realize mechanized operations on wheat, rice and other crops, it has advantages such as multi-purpose machine, high price-quality ratio, strong adaptability, high work efficiency, low failure intensity, small loss coefficient and good cleaning effect.

Product Features:

1. Adopts common axis double hammer separating drum technology, The hammer separating drum is composed of two parts: grinding zone and separation zone. The materials are first crushed and brushed cleaned in the grinding zone, and then rotated and transported to the separation zone for separation, realizing multi-stage grinding and multi-stage separation, small impact on crops and low crushing speed, high operating efficiency, not easily blocked when cleaning wet crops.

2. The cleaning system is equipped with leaf-type street fan with adjustable speed, double-layer adjustable shellfish grille and elongated tail grille with adjustable amount of air and angle. The cleaning area is larger and the cleaning effect is good.

3. Drum speed control uses stepless transmission structure, and the speed control range is large, which can meet the cleaning requirements of various crops.

4. Electronic sensors are installed on the key operating components to monitor the operation of the harvester's key components in real time, and a rear view system is installed, providing a reliable guarantee for the driver's good driving.

5. Uses reinforced floating feeding roller to cross bridge. It can realize fast grip to the sleeve, has good versatility, easy to operate and reliable grip.

6. The drive system uses hydrostatic drive technology, the power selection uses the design of the gearbox, which has simple design and low failure rate.

7. Open enlarged grain storage and high-level horizontal hydraulic unloading pipe are applied, grain unloading height is high, and grain unloading speed is fast.

8. The same main machine can realize the free switching technology of full axial flow separating drum, cutting flow hammer drum and straw mower separating device, convenient replacement, one machine is used for many purposes, the price-quality ratio is high and the adaptability is strong.

9. 8-row corn harvester can perform double-sided folding with one button, the roadway clearance is good.

10. 635mm wide rubber semi-track can be selected and installed, increase the grounding area, reduce the specific grounding pressure of the vehicle, improve the vehicle's permeability to ensure normal harvesting under harsh conditions such as slippery ground surface, reduce the degree of soil compaction and protect arable land, effectively reduce fuel consumption at the later stage of soil treatment and save energy and reduce cost.
