Description

Multifunctional rotary tillage and ridge building machine

technical field

The utility model belongs to the technical field of agricultural machinery, in particular to an agricultural mechanical equipment for building field ridges.

Background technique

For a long time, the construction of ridges in farmland, especially paddy fields, has been done by manpower. Even with the help of some special tools, the labor intensity is still high, the work efficiency is low, and the uniformity and consistency of the ridges are poor, which requires manual trimming, especially Also do not have the implement that is specially used in paddy field ridge building so far.

Moreover, the time to build the field ridges is often at the time when agriculture, rural areas and farmers are on the scene, cotton and other economic crops are being managed, and the labor force is extremely tense. Relying on manpower to complete the field ridge construction often delays the farming time and causes losses to agricultural production.

For mulch crops, it is often necessary to plant ridges between rows before watering the tops. Because it is not suitable to use pre-sowing land preparation machines for ridges at the seedling stage of crops, it is often only possible to use human work stalks, which is time-consuming, laborious, poor in quality, and low in efficiency. Often after watering "Collapsed ridge" affects the quality of irrigation, causes great difficulties in field management of crop seedling stage, and also has a certain degree of influence on crop yield.

At present, there is a kind of ridge building machine configured on a small four-wheel tractor, which is a disc type ridge building machine. The disc ridge building machine consists of a frame on which left and right disc plow bodies are installed, left and right guide forming plates are installed behind the left and right disc plow bodies, and a suppressor is installed on the frame behind the guide forming plates. wheel device.

Detailed ways

Below in conjunction with accompanying drawing, the structure of multifunctional rotary tillage ridge building machine of the present utility model is described in detail. Fig. 1 and Fig. 2 are respectively the three-dimensional schematic view and the top view structure schematic diagram of the overall structure of the rotary tillage ridge building machine. Suspension frame 2, rotary tiller shaft 9, transmission chain assembly 12, spiral soil collector 10, forming wheel 4, compacting oil cylinder 3 and two side connecting plates 6,7 form.

The frame 15 is composed of two side connecting plates 6, 7 and two connecting beams 8 to form a frame structure, and other assemblies are installed on the frame structure. A three-point suspension frame 2 is installed on the front connecting beam 8 as the traction device of the wheeled tractor, and a transfer case 11 is placed on the two connecting beams 8 of the frame 15 at the same time, and the cardan shaft 1 of the transfer case 11 serves as The power input shaft of the transfer case 11 is equipped with universal joints at both ends, and the universal drive shaft 1 is connected to the power output shaft at the rear end of the wheeled tractor. Frame 2 cooperates as traction device, to adapt to the requirement of actual field work, provide the flexibility on the use of utility model rotary tillage ridge builder.

Rotary cultivator shaft 9 and spiral soil collector 10 are installed between two side connecting plates 6 and 7, and its relative position is that rotary cultivator shaft 9 is positioned at frame 15 fronts (according to advancing direction), and spiral soil collector 10 is on rotary cultivator blade At the rear of the shaft 9, the rotation of the rotary tiller shaft 9 loosens the soil, and at the same time realizes that the dry soil on the upper layer of the soil and the moist soil on the lower layer are evenly stirred; Stir and pool to central outlet.

The rotating shaft of forming wheel 4 is installed on the rear central position of frame 15 by a T-shaped frame 18, and the other end of T-shaped frame 18 is hinged on the rear connecting beam 8, between the T-shaped frame 18 middle beam and the rear connecting beam 8 Compression hydraulic cylinder 3 is also set between. The forming wheel 4 is positioned at the rear of the central outlet, and rolls and forms the loose soil gathered into the central outlet through the spiral soil collector 10 . Due to the effect of pressing the hydraulic cylinder 3, the formed trapezoidal ridge of the forming wheel 4 can be compacted. This forming wheel 4 is a forming wheel whose width can be adjusted. Adapt to different needs. Forming wheel 4 is made up of two cones and an axle, and the surface of this axle is a smooth surface. The two cones are sleeved on the shaft, using the two conical surfaces and the circumference of the shaft, the three assemblies are driven to roll by the gripping protrusions on the cones and side friction, so that the soil is rolled into a standard trapezoidal section.
