Description

Shovel opener shovel head

technical field

The utility model belongs to agricultural machinery, and mainly relates to a shovel-type ditch opener shovel head for fertilizing and ditching.

Background technique

Most of the currently used fertilization openers are shovel-type openers, and the shovel heads on the shovel-type openers are all rectangular strip-shaped flat plates. In practice, not only the operation resistance is large, the power consumption is large, but also the The amount of disturbance to the soil during the ditching process is large, and it is easy to bury and press seedlings, and the operation quality is poor.

Contents of the invention

The purpose of this utility model is to solve the problems existing in the shovel head with a rectangular strip-shaped flat structure on the existing shovel opener, and to design and provide a shovel head of a shovel type opener with a new structure, so that the operation resistance is small and the power consumption is low. The purpose of reducing seedling burying and pressing seedling rate and improving operation quality is less.

The basic design of the utility model is that the overall outline of the shovel head of the shovel type ditch opener is formed by sequentially connecting the rear elevation, the upper arc surface, the front slope and the lower bottom surface; wherein: the angle _α between the rear elevation and the lower bottom surface is 95 °, the angle α ₂ between the front slope and the bottom surface is 35°, and the angle α ₃ between the bottom surface and the horizontal plane is 5°; the height dimension H of the rear facade is 72 millimeters, and the longitudinal length dimension L of the bottom surface is 140 mm, the lateral width dimension S of the rear facade, upper arc surface, front slope and lower bottom surface is 20 mm; the arc radius dimension R of the upper arc surface is 120 mm, thus forming the shovel head of the shovel opener .

The utility model has novel structural design, scientific and reasonable determination of technical elements and mutual matching selection, small operation resistance, low power consumption, energy saving, low seedling burying and pressing rate, and good operation effect. The shovel head can be used not only for fertilizing and ditching, but also for deep loosening of soil, and has a wide range of applications.

Detailed ways

The best implementation of the utility model will be described in detail below in conjunction with the accompanying drawings. A shovel head of a shovel type ditch opener, the overall outline of the shovel head of a shovel type ditch opener is composed of a rear facade 1, an upper arc surface 2, a front slope 3 and a lower bottom surface 4 in sequence; wherein: the rear facade 1 The included angle α ₁ with the bottom surface 4 is 95°, the angle α ₂ between the front slope and the bottom surface is 35°, and the angle α ₃ between the bottom surface and the horizontal plane is 5°; the height dimension H of the rear facade 1 is 72 millimeters, the longitudinal length dimension L of the lower bottom surface 4 is 140 millimeters, the lateral width dimension S of the rear facade 1, the upper arc surface 2, the front slope 3 and the lower bottom surface 4 is 20 millimeters; the circle of the upper arc surface 2 The arc radius dimension R is 120mm.

When in operation, the shovel head of the shovel opener is fixed on the front end of the shovel handle of the shovel opener and assembled on the implement.

In the shovel head structure and technical parameter tests determined by multiple parameter matching scientific research tests, under the same operating conditions, the shovel head reduces the traction resistance by 15-20% compared with the traditional shovel head, and the rate of soil embedding and pressing seedlings is reduced by 30%. -40%, the technical effect is prominent and obvious.
