Description

Bionic finger type elastic side throwing straw cleaning wheel

technical field

The invention and creation belong to agricultural machinery, and mainly relate to an operation part which is equipped on a no-tillage seeding machine and is used for cleaning straws.

Background technique

The straw cleaning wheel is a working part used to remove the residual straw covering the surface of the field to obtain a clean seeding belt on the surface of the land and provide good seed bed conditions for the sowing operation of the no-till planter. Ensuring and improving the quality and efficiency of no-till seeding operations plays a vital role. The current straw cleaning wheels are rigid integral roulettes punched from metal sheets or metal fused and cast, and gaps are evenly distributed around the circumference of the roulette. During the operation, the gap of the straw cleaning wheel is inserted into the residual straw and soil on the surface. During the whole forward movement, the resistance of the soil and straw makes it rotate passively. bring. However, in the production and use practice, it is found that the straw cleaning wheel of this structure has insufficient lateral throwing force on the residual straw on the surface, and there are technical problems such as small straw lateral displacement distance, low straw clearing rate and poor straw clearing quality, and the working depth is unstable and cannot be Adapt to and meet the quality requirements of no-tillage precision seeding operations for seed bed strips.

SUMMARY OF THE INVENTION

The purpose of the invention is to research and design a new structure of bionic finger-type elastic side-casting straw cleaning wheel in view of the problems existing in the above-mentioned prior art, combined with the actual needs of no-tillage precision seeding mechanized operation, so as to achieve good straw cleaning effect. , High efficiency, good quality of strip seed bed, reliable operation, meet and adapt to the purpose of no-tillage and precision sowing operation.

The purpose created by the present invention is achieved as follows: the bearing is fixedly installed in the shaft hole of the bearing seat, the web is fixedly mounted on the outside of the bearing seat through the fastener group A, and the radial direction is on the same side of the web. N number of finger-reeling barrel seats are evenly distributed and fixed at the same radius part, and each finger-removing barrel seat is swung circumferentially through the pin shaft to install the straw-removing finger welding, and the same radius along the circumferential direction on the spoke The number of fastener groups B equal to the number of N finger-reeling cylinder seats is evenly distributed at the parts, and the fastener group B is inserted into the through hole on the inner side of the corresponding straw-removing finger-welding joint. , there is a space between the through hole and the fastener group B, the pressure spring is fitted on the fastener group B, and the two ends of the pressure spring are respectively welded with the spoke plate and the straw clearing finger to form a contact fit. On the other side of the web, there is a fixed anti-skid limit deep ring that is coaxial with the bearing seat through screws. The diameter of the anti-skid limit deep ring is Φ ₂ smaller than the size of the rotation diameter Φ ₁ for the welding of the straw clearing finger and the finger. So far, the bionic finger-type elastic side throwing straw cleaning wheel is formed.

The invention creates a structure in which the front claws dig and throw soil when burrowing animals build a burrow, and adopts a structure in which the straw-removing fingers are welded to the spoke plate and can swing back and forth in the axial direction, so that the straw-removing wheel can move the residual straw on the surface to two directions. The straw cleaning operation of the side throwing completes the processing of the strip seed bed. It has the characteristics of novel, unique and reasonable structure, good straw clearing effect, high efficiency, good quality of the strip seed bed, reliable use and few failures. It is a no-tillage The promotion and application of precision seeding agronomic technology provided technical support.

Detailed ways

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A bionic finger-type elastic side throwing straw cleaning wheel, the bearing 10 is fixedly installed in the shaft hole of the bearing seat 5, and the web 1 is fixed on the outside of the bearing seat 5 through the fastener group A4. On the same side of 1 along the same radius in the circumferential direction, N number of finger-removing barrel seats 11 are evenly distributed and fixed, and on each finger-removing barrel seat 11, through the pin shaft 7, a stalk-clearing finger-removing welding joint 6 is installed in a circumferentially oscillating manner. , the number of fastener groups B9 equal to the N number of finger-reeling bases 11 is evenly distributed at the same radial position along the circumferential direction on the spoke plate 1, and the fastener group B9 is inserted in the corresponding The straw clearing finger is welded into the through hole on the side of 6, and there is a space between the through hole and the fastener group B9. The pressure spring 8 is fitted on the fastener group B9. The ends are in contact with the spoke plate 1 and the straw-clearing finger welding 6 respectively. On the other side of the spoke plate 1, the fixed anti-skid limit deep ring 2 is coaxial with the bearing seat 5 through the screw 3. The diameter dimension Φ ₂ of the depth-limiting ring 2 is smaller than the rotational diameter dimension Φ ₁ of the straw-cleaning finger welding 6 .

During operation, the current wheel is rotatably mounted on the implement through the bearing 10, and moves forward randomly. Under the control of the contact between the anti-skid limit deep ring 2 and the ground support, the outer end of the straw-cleaning finger welding 6 is inserted into the residual straw and soil on the ground. The joint 6 drives the overall follow-up rotation of the web 1. At the same time, under the action of the axial extrusion force of the residual straw and soil, the joint 6 rotates around the pin shaft 7 on the web 1. The compression force of the pressure spring 8 increases, and when the outer end of the straw-clearing finger welding 6 rotates to be out of engagement with the soil, under the action of the pressure spring 8 with the increased compressive force, the straw-clearing finger welding 6 is on the web 1 The upper winding pin 7 rotates in the opposite direction and returns to the initial position, and its axial force throws the residual straw to the outside of the web 1 to complete the straw cleaning operation of the strip seed bed processing. The straw removal rate is high and the seed bed strip is clean.
