Problems solved by technology

[0003] (1) Imported harvesting machines are expensive, with a price of about 1.35 million each, which is beyond the reach of ordinary enterprises, and it is even more difficult for growers to purchase by themselves, hindering the promotion of tomato mechanized harvesting;
[0004] (2) Since foreign companies monopolize the key technologies of harvesters, and a large number of non-standar

Example Embodiment

[0057] Example 1:

[0058] Reference attached figure 1 -Attached Figure 7 The structure of the tomato processing combine harvester matched with this embodiment includes a frame 16 and wheels. A cutter 1 is provided in the front of the frame 16. The frame 16 is equipped with a transmission mechanism and a vine fruit separating device 8. The transmission mechanism includes a vine and fruit transmission mechanism 4, a fruit transmission mechanism 11, and a vine and fruit transmission mechanism 9. The cutter 1 and the vine and fruit separation device 8 are connected by the vine and fruit transmission mechanism 4. The fruit transmission mechanism 11 and the vine transmission mechanism 9 are placed Below the vine and fruit separating device 8, and the fruit transmission mechanism 11 is placed below the vine transmission mechanism 9, and the fruit transmission mechanism 11 is connected to an external transmission belt 13. A color sorting device 24 is provided on the external transmis...

Example Embodiment

[0071] Example 2:

[0072] Compared with Embodiment 1, the difference of this embodiment is that a liquid level gauge, a temperature probe, an oil drain valve and an air filter are installed on the oil tank 53.

Example Embodiment

[0073] Example 3:

[0074] Compared with Embodiment 1, the difference of this embodiment is that in the second hydraulic circuit, a one-way variable motor is used instead of the vine fruit separating device motor 27. This can simplify the mechanical structure of the tomato harvester. The vine and fruit separation device described in the structure of the tomato harvester originally designed contains two parts: the swing mechanism 43 and the spring-tooth drum 42. The swing mechanism 43 is derived from the power source. The rotary motion of the fruit separating device motor 27 is converted into a variable-speed rotary motion, and the action of driving the spring-toothed drum 42 completes the separation of tomato fruit seedlings. The swing mechanism 43 can be omitted, and a one-way variable motor is used to directly drive the spring-toothed drum 42. By periodically adjusting the flow rate and direction of the unidirectional variable motor through the solenoid valve, the periodic rota...

Abstract

The invention relates to a hydraulic system for an agricultural machine, in particular to a hydraulic system for a self-propelled tomato harvester. The hydraulic system comprises five independent hydraulic loops; the five hydraulic loops share an oil tank; and an air cooler and a return oil filter are arranged on a master return oil passage. The hydraulic system for the self-propelled tomato harvester has stable transmission and reliable performance, and is easy to implement multiple complex mechanical operations such as lifting, transmission, steering and the like; and when the hydraulic system is used with the corresponding tomato harvester, the tomato harvester has a power system with excellent performance and further can finish tomato harvesting operation with high quality and high efficiency.

Description

Technical field: [0001] The invention relates to a hydraulic system of an agricultural harvesting machine, in particular to a hydraulic system for a self-propelled tomato harvester. Background technique: [0002] With the increasing expansion of the tomato industry in Xinjiang, the planting area of ​​processed tomatoes is gradually increasing, and the low-cost and timely harvest of tomatoes has become a key factor restricting the sustainable and rapid development of the tomato industry. Processing tomato has strong seasonal harvest, high labor intensity and high cost, accounting for about 50% to 70% of the production cost. At present, my country's processed tomatoes mainly rely on manual harvesting, which is highly efficient and low cost, and it is difficult to harvest timely, which affects the quality of tomato products. The mechanized harvesting of processed tomatoes can not only reduce the cost of raw materials, but also improve product quality and competitiveness in the...
