Hydraulic system for two-row sugarcane transverse planter and control method

Abstract

The invention discloses a hydraulic system for a two-row sugarcane transverse planter. The hydraulic system comprises a hydraulic source, an assistant wheel lifting control loop, an earthing mechanismlifting control loop and a ditcher lifting control loop, the hydraulic source is used for providing oil for each loop, the assistant wheel lifting control circuit is used for controlling lifting andlowering operation of wheels on two sides of an assistant mechanism, the earthing mechanism lifting control loop is used for controlling lifting and lowering operation of wheels on two sides of an earthing mechanism, the ditcher lifting control loop is used for controlling synchronous lifting and lowering operation of wheels on two sides of a ditcher, and an output loop of the hydraulic source iscommunicated with the assistant wheel lifting control loop, the earthing mechanism lifting control loop and the ditcher lifting control loop through a multiway valve. The invention further discloses ahydraulic control method of the hydraulic system. The method includes steps of hydraulic oil supply and hydraulic oil return. The hydraulic system can effectively control lifting and lowering sequence and speed of each part and has pressure maintaining effect, thereby being stable and reliable in pressure.

Description

technical field [0001] The invention belongs to the field of hydraulic technology, in particular to a hydraulic system controlled by multiple cylinders, in particular to a hydraulic system and a control method for a double-row sugarcane horizontal planter. Background technique [0002] Sugarcane is still an important sugar crop in my country, especially in the south. At present, our country is slowly promoting sugarcane mechanized planting and harvesting, etc., but in terms of usage, the promotion effect of sugarcane mechanized planting is not ideal. Among existing sugarcane planting machines, there are two main sugarcane planters, one is a real-time seed-cutting type sugarcane planter, and the other is a pre-cut seed type sugarcane planter. The real-time seed-cutting sugarcane planter adopts real-time cutting of sugarcane at a fixed distance, and plants the sugarcane into the opened ditch. According to the function, it is divided into machines that only plant and can conti...

Problems solved by technology

The real-time seed-cutting sugarcane planter adopts real-time cutting of sugarcane at a fixed distance, and plants the sugarcane into the opened ditch. According to the function, it is divided into machines that only plant and can continuously complete ditching, seed dropping, fertilization, and film covering. 1. Planting machines with soil-covering functions are the most used planting machines that only complete the planting function. It takes a lot of time and manpower to complete all the procedures of sugarcane planting. In addition, the real-time seed-cutting planter belongs to blind cutting. The probability of damaging the buds is extremely high, and the cut sugarcane segments fall directly into the ditch, so the planting density is not uniform enough, and the probability of seed leakage is extremely high

The pre-cut sugarcane planter stores the cut and screened cane seed segments in large seed boxes, then transfers them in batches and drops them to the seed discharge port, and then falls into the ditch from the seed discharge port. The functions are also divided into sugarcane planters that are only used for planting and sugarcane planters that can continuously complete the functions of ditching, seed dropping, fertilization, film covering, and soil covering. The pre-cut seed planter is cut and screened in advance for the cane species. Therefore, the quality of the sugarcane seeds is very good, and there is little damage to the buds. However, the same problem is that the sugarcane seeds fall directly into the ditch, lacking seed fall control, so the planting density is extremely uneven.

Moreover, all the above-mentioned sugarcane planting machines are only suitable for the current common vertical sugarcane planting method, and there is a lack of corresponding mechanical equipment for the new horizontal planting method
