Description

Tillage machine side drive front multifunctional operation machine

technical field

The utility model belongs to an agricultural machine, which is a side-drive and front-mounted multifunctional operation machine for a cultivator.

Background technique

The traditional rotary tiller, of course, also includes working machines such as ditching, shoveling, and raising soil. On the rear side of the gear box. Just like the relationship between an ox and a plow, the ox walks in front and the plow is dragged by the ox behind. The farmer holds the handle of the plow with one hand and controls the whip with the other. There are many shortcomings or deficiencies in the existing front-mounted cultivating machines. The first is that there are dead angles when plowing. In places close to the ridge, the rotary tiller cannot reach and plow. For a large number of small fields, workers need to pay Digging, the efficiency is difficult to improve; the second rotary tiller is close to the operator, which not only poses a safety hazard, but also splashes mud and dust on the body, which is very unsanitary; third is for ditching, soil cultivation, ridge raising, weeding, etc. The working mechanism of operation also has the same problem, and it is very desirable to improve these problems. There are reports of front-mounted rotary tillers at present, but a brand-new design is not easy to transform for a large number of old rotary tillers that exist.

Contents of the invention

The purpose of this utility model is to propose a side-drive front-end multi-functional operation machine for a cultivator, so that it can perform operations such as rotary tillage, ditching, ridge raising, soil cultivation and weeding without leaving any dead ends, and mud and dust will not be splashed on the operator. It is safer and more convenient to operate, and it is convenient to transform the old rotary tiller, so as to overcome the shortcomings of the existing technology.

This utility model proposes this tillage machine side drive front multifunctional operation machine, which has engine frame, three-way gear box, two-way gear box, speed change transmission chain, interchangeable rotary tiller, ditching knife and The weeding disc is characterized in that the two-way gearbox is installed on the engine frame, parallel to the output shaft of the tiller gear transmission box, and there is a transmission chain between the two shafts to connect the transmission, the two-way gear box and the three-way at the front lower end of the engine frame There is a rotary tillage box connecting shafts between the gearboxes. The output shaft of the three-way gearbox is equipped with interchangeable rotary tiller knives, ditching knives and weeding discs. The upper end of the three-way gearbox has a lifting screw connected to the engine frame. , the rotary tiller box coupling shaft is fixed outside the rotary tillage box coupling shaft shell.

Interchangeable tiller, ditch and weeding discs with fenders behind.

The variable speed drive chain can be a gear drive or a chain drive.

The working process of the present utility model is like this:

The power of the engine is output through the shaft of the gear transmission box, then transmitted to the two-way gear box through the variable speed transmission chain, and then transmitted to the three-way gear box through the rotary tillage coupling shaft, and finally drives the rotation of the rotary tiller on the output shaft of the three-way gear box , with the rotation of the iron wheel, the rotary tiller plows the field forward synchronously. When stopping work, move the clutch operating mechanism on the handrail to stop the rotary tiller and the iron. To adjust the plowing depth, twist the lifting screw, adjust the height of the rotary tiller to the desired position, and then plow according to the new requirements.

When crossing ridges or ridges, you can first adjust the rotary tiller to the highest position, and just move forward with the handrail in hand.

The utility model is characterized in that it not only maintains the advantages of the existing rotary tiller that can be used for multiple purposes, and can perform operations such as rotary tillage, ditching, ridge raising, soil cultivation and weeding, and there are no dead spots or very few dead spots on the cultivated land. Simultaneously, the utility model has the advantages of simple structure, which is convenient for transforming the existing old rear-mounted rotary cultivator, and improves the efficacy of the old equipment.

Detailed ways

As shown in the figure, an engine frame 3 of corresponding size is installed on the existing 1Z-31 type cultivator walking tractor or rotary cultivator gear transmission box 8, the two-way gear box is contained in the bottom of the engine frame, and the two-way Two parallel shafts of gear box and rotary cultivator gear transmission box are connected with variable speed transmission chain 6. Because the transmission chain is placed on the side of the gear transmission box of the walking tractor, it is called side drive. The rotary tiller casing 4 between the two-way gear transmission box and the three-way gear transmission box 1 is located at the center of the frame. The two ends of the output shaft of the three-way gear box can be installed or replaced with a rotary tiller 12, a weeding disc 10 and a ditching knife 13.

The fender is installed on the frame to block the mud and dust rolled up when the rotary tiller, ditch knife and weeding disc rotate, so as to protect the operator from harm.

The elevating screw rod 2 that connects three-way gear box and engine frame can allow the position within about 15cm of rotary cultivator lifting up and down, so that adjust the degree of depth of tillage.

A clutch operating mechanism 5 is set on the transmission chain to realize the power clutch between the working mechanism and the engine.

All the other parts are existing commercially available accessories as hand frame 7, iron wheel 9, cultivator gear transmission case 8.

Parts and symbols not mentioned are as above.

The overall dimensions (mm) of the whole machine are 2100 long, 750 wide and 1100 high. It weighs about 160-180Kg.

The positive effects of this example are reflected in:

The machine is modified with a 1Z-31 gear transmission box, equipped with an R180 engine, and the rotary tiller, ditching knife, and weeding disc are all commercially available products. The efficiency of plowing is 2-3 mu/hour after trial use; The ditch is 40-50cm wide and the efficiency of the 250-300cm deep soil ditch is 600-800m/hour. Orchard weeding is satisfactory.

Average fuel consumption: 0.8-1.1 liters/mu for plowing; 0.7-0.9 liters/mu for cultivated land.

The cost plus a certain profit and tax is about one-third of the value of a farm ox, which can be accepted by the majority of farmers and is convenient for promotion and transformation.

1Z-41, 51, 61, 81, 101 are suitable for the working efficiency of each model modification model, and the advantages are as mentioned above.
