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-standard parts are used in imported harvesters, the maintenance of parts must be sent abroad, which seriously affects the timely and low-cost repair and maintenance of harvesters. The harvest season has seriously affected the normal operation of the harvester;
[0005] (3) Foreign harvesters cannot fully adapt to the requirements of Xinjiang tomato varieties, planting modes, and use conditions.

Embodiment 1

[0058] Refer to attached figure 1 - attached Figure 7 , the structure of the matching processing tomato combine harvester of the present embodiment comprises frame 16, wheel, is provided with cutter 1 at the front portion of frame 16, and frame 16 is provided with transmission mechanism, rattan fruit separation device 8, described The transmission mechanism includes a vine and fruit transmission mechanism 4, a fruit transmission mechanism 11 and a vine transmission mechanism 9, the cutter 1 is connected with the vine and fruit separation device 8 through the vine and fruit transmission mechanism 4, and the fruit transmission mechanism 11 and the vines transmission mechanism 9 are placed Below the vine and fruit separation device 8, and the fruit transmission mechanism 11 is placed below the vine transmission mechanism 9, and the fruit transmission mechanism 11 is connected with the external transmission belt 13. A color sorting device 24 is provided on the external transmis...

Embodiment 2

[0072] Compared with Embodiment 1, this embodiment differs in that the oil tank 53 is equipped with a liquid level gauge, a temperature measuring probe, an oil drain valve and an air filter.

Embodiment 3

[0074] Compared with Embodiment 1, the difference of this embodiment is that in the second hydraulic circuit, a unidirectional variable motor is used to replace the motor 27 of the vine and fruit separating device. The mechanical structure of the tomato harvester can be simplified like this, the rattan fruit separating device described in the structure of the tomato harvester of original design comprises two parts, the swinging mechanism 43 and the spring tooth drum 42, and the swinging mechanism 43 controls the vines from the power source. The rotary motion of the fruit separation device motor 27 is converted into a variable speed rotary motion, and the spring tooth cylinder 42 is driven to complete the separation of tomato seedlings. The swing mechanism 43 can be omitted, and a unidirectional variable motor is directly used to drive the spring tooth cylinder 42. The periodic rotation of the spring tooth cylinder 42 can also be realized by periodically adjusting the flow rate ...

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...
