Description

A multifunctional field management machine

technical field

The utility model relates to the field of agricultural machinery, in particular to a multifunctional garden management machine.

Background technique

The frequent operation of high-power tractors in and out of the field increases the compaction of the soil, destroys the soil structure, and is not conducive to the growth of crops, and reserving fixed tractor roads will lead to waste and loss of a large area of arable land; Fields, tea gardens, corn, cotton and other crops are all planted with unique ridge farming. The plants are tall and the ridge spacing is small. It is not convenient for large and medium-sized tractors to perform intertillage operations such as ditching, weeding, spraying, and ridges on the above crops. A miniature machine for agricultural operations.

For farmers in mountainous and hilly areas, areas with finely divided plots and orchards, it is even more difficult for large machines to work in the fields. There is a shortage of miniature agricultural machinery suitable for mountainous and hilly areas on the market.

A large number of vegetable and flower planting bases and agricultural bases with greenhouse facilities have emerged in the suburbs and urban-rural junctions. For plowing and land preparation, relying on traditional tractor-mounted plows or high-power rotary tillers can no longer meet the needs of the above-mentioned farmers. The emergence of a flexible and adaptable multifunctional micro-machine.

The multifunctional pastoral management machine solves this problem well. The multi-functional pastoral management machine is also called gardening management machine or miniature tillage machine for short. The supporting power is mostly 1.5-6Kw air-cooled gasoline engine or diesel engine, and 2.2-5.1Kw power is generally used. At present, there are mainly two types of models produced and sold in China: one is powered by air-cooled gasoline engine or water-cooled diesel engine, belt and gear box are used as two-stage transmission device, and equipped with rotary tiller with a tillage width of 500-1200mm , the price is generally 3000-3500 yuan, but the disadvantage is that the multi-purpose expansion capacity is limited, and it is only suitable for simple operations such as rotary tillage and ditching, and generally cannot be used for weeding, especially for intertillage spraying. The other is powered by an air-cooled diesel engine or a high-horsepower air-cooled gasoline engine, with a full gearbox as a transmission device, and a rotary tiller with a tillage width of 800-1350mm. The price is 5500-6500 yuan. The weight of the machine is heavy, the operation is cumbersome, the power consumption is serious, and the fuel economy is poor. limit.

Detailed ways

As shown in the figure, a multi-functional pastoral management machine is provided with an engine 2, an emergency stop device 8 and a transmission gearbox 3 on the frame 1, and a tillage implement 5 and a walking device 6 are arranged below the frame 1. One side of 1 is provided with handlebar 7, and gear box 3 is provided with primary chain transmission mechanism 9, secondary chain transmission mechanism 10 and bevel gear transmission mechanism 11, and engine 2 drive shaft is driven by belt transmission mechanism 4 and primary chain transmission mechanism. The mechanism 9 is connected, the primary chain transmission mechanism 9 is connected with the tillage implement 5, the primary chain transmission mechanism 9 is connected with the secondary chain transmission mechanism 10 through the bevel gear transmission mechanism 11, and the secondary chain transmission mechanism 10 is connected with the running gear 6.

A drug pump 12 is arranged above the speed change gear box 3 , and a hook device 13 is set at one end of the speed change gear box 3 .

The emergency stop device 8 is composed of a hand brake 801, a return spring I 802, a pull cord 803, a tensioning wheel clutch 804 and a return spring II 805, and the hand brake 801 arranged at the handlebar 7 is connected to the pull cord 803 through the return spring I 802 , one end of the pull rope 803 is connected to the tensioning clutch 804 arranged under the belt transmission mechanism 4 , and the tensioning clutch 804 is connected to the frame 1 through the return spring II 805 .

The tensioning clutch 804 is a tensioning wheel, and is arranged under the belt of the belt transmission mechanism 4 .

Start engine, at this moment because tensioner pulley pressure band type clutch is subjected to the pulling force of return force spring, first-stage transmission mechanism belt drive is in slack state, so engine idling, power can not transmit backward.

Press down the operating hand brake of the emergency stop device to the handlebar, pull the tension wheel clutch through the cable, the belt transmission mechanism effectively engages the engine power, and transmits it backwards. The belt transmission mechanism transmits the power to the transmission gearbox, and the transmission gearbox The internal primary chain transmission mechanism drives the tillage equipment to rotate, which can complete operations such as rotary tillage, ditching, and weeding; the medicine pump is connected to the transmission shaft of the primary chain transmission mechanism through the sprocket, and the coaxial rotation of the sprocket and the tiller drives the pesticide. The pump is working. At the same time, the primary chain transmission mechanism continues to transmit the power backward to the bevel gear transmission mechanism. A bevel gear of the bevel gear transmission mechanism is coaxial with the secondary chain transmission mechanism, and the driving wheel is driven by the secondary chain transmission mechanism. go ahead. The hitch is equipped with a tow bucket to easily realize efficient disassembly and assembly actions, which is convenient for expanding short-distance transportation of goods.

When the operator needs to leave the machine actively or passively to stop the machine immediately, he only needs to loosen his hands and disengage from the operating handlebar. When the tensioning wheel is loosened, the belt drive will immediately cut off the power of the engine, so the traveling wheels and working parts will lose power simultaneously, which will not cause harm to personnel and machines.
