Description

Technical Field

[0001] The invention belongs to automatic control equipment, mainly relates to an electric-controlled induction dispenser. Background Art

[0002] Since the beet lifting wheel installed on the traditional beet harvester does not have an automatic patrol adjustment structure and function during the pulling operation, beets are easily missed and damaged due to the offset of the planting and growth position of the beets during the beet pulling and harvesting operation. In order to solve the above technical problems, a beet harvester using a mechanical hydraulic beet lifting and automatic patrol device has been developed and applied, which improves the beet harvest rate and reduces the damage rate compared with traditional machines. However, in many years of production and use practice, it is found that the patrol device not only has technical defects such as complex structure, high manufacturing cost and failure rate, especially slow response, slow adjustment and lag, the problem of beet missing and damage still exists, and it cannot adapt to and meet the requirements of high-efficiency and high-quality beet harvesting operations. Summary of the invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, and in combination with the current actual needs for high-quality and efficient mechanized harvesting of sugar beets, to develop an electrically-controlled inductive distributor that can be installed on a pull-wheel type sugar beet harvester. By adopting an electrically-controlled inductive distributor with high electrical signal sensing sensitivity and fast response to perform real-time patrol and regulation during the pull-wheel operation, the purpose of greatly reducing the sugar beet harvesting miss-pulling rate and damage rate, simple structure and fewer operating failures is achieved.

[0004] The purpose of the invention is achieved as follows: a coaxial support A and support B are fixed on the seat plate, a stepped drive shaft is circumferentially and radially positioned, and axially reciprocatably supported and inserted on the support A and support B, a sheet seat is fixed on the portion of the stepped drive shaft between the support A and the support B, a sensing sheet A and a sensing sheet B are fixed on both ends of the sheet seat, a proximity switch A and a proximity switch B are fixed on the seat plate at both sides of the sheet seat, the proximity switch A and the proximity switch B cooperate with the sensing sheet A and the sensing sheet B respectively, and the stepped drive shaft can be sequentially moved at the outer portion of the support A. The compression spring seat A and the compression spring seat B are axially reciprocatingly mounted, and the pressure spring is mounted on the portion between the compression spring seat A and the compression spring seat B in a squeeze fit. The positioning baffle screw mounted on the outer end surface of the stepped drive shaft axially positions the compression spring seat A on the stepped drive shaft. The compression spring seat B is in contact or out of contact with the shoulder and support A on the stepped drive shaft. A compression spring seat housing is fixedly mounted on the outer end surface of the support A. The compression spring seat housing integrally encompasses the compression spring seat A, the pressure spring and the compression spring seat B. The compression spring seat A is in contact or out of contact with the inner wall surface of the bottom wall of the compression spring seat housing, thereby forming an electrically controlled induction distributor.

[0005] The invention can be installed on machines such as beet harvesters, mechanical tillage and weeding machines, and various operating machines that require patrol and regulation to complete real-time automatic adjustment control when the machines are operating. It has the characteristics of novel, unique, simple structure, easy and convenient configuration and installation on the machines, fast and timely electrical signal response, good patrol and regulation effect, high efficiency, wide application range, and high degree of commonality.

[0010] The following is a detailed description of the implementation scheme of the invention in conjunction with the accompanying drawings. An electrically controlled inductive distributor, with coaxial fixed supports A7 and B11 on a seat plate 1, a stepped drive shaft 8 circumferentially and radially positioned, axially reciprocatably supported and inserted on supports A7 and B11, a sheet holder 14 fixed on the stepped drive shaft 8 between supports A7 and B11, induction sheets A9 and B12 fixed on both ends of the sheet holder 14, proximity switches A10 and B13 fixed on the seat plate 1, on both sides of the sheet holder 14, respectively, the proximity switches A10 and B13 cooperate with the induction sheets A9 and B12, respectively, and the stepped drive shaft 8 is located between the supports 1 and 2. The outer side of A7 is successively and axially reciprocatingly mounted with the compression spring seat A3 and the compression spring seat B6, and the compression spring 5 is mounted on the position between the compression spring seat A3 and the compression spring seat B6 in a squeeze fit, and the positioning baffle screw 4 mounted on the outer end surface of the stepped drive shaft 8 axially positions the compression spring seat A3 on the stepped drive shaft 8, and the compression spring seat B6 is in contact or out of contact with the shoulder and the support A7 on the stepped drive shaft 8, and a compression spring seat housing 2 is fixed on the outer end surface of the support A7, and the compression spring seat housing 2 integrally encloses the compression spring seat A3, the pressure spring 5 and the compression spring seat B6, and the compression spring seat A3 is in contact or out of contact with the inner wall surface of the bottom wall of the compression spring seat housing 2.

[0011] During operation, the electric control induction distributor is installed on the pull-wheel type beet harvester through the base plate 1 as a whole and moves forward randomly. When the beet pull-wheel deviates from the beet crop, the deviating action of the beet pull-wheel drives the stepped drive shaft 8 to move axially on the support A7 and the support B11. When moving to the right, the induction sheet A9 approaches the proximity switch A10, and its electrical signal is adjusted through the electromagnetic valve and drive system on the beet harvester to automatically align the deviated beet pull-wheel with the beet; when moving to the left, the induction sheet B12 approaches the proximity switch B13, and its electrical signal is adjusted through the electromagnetic valve and drive system on the beet harvester to automatically align the deviated beet pull-wheel with the beet, completing the automatic patrol and real-time regulation, thereby improving the harvest rate of beets and reducing the beet damage rate. When no deviation occurs, the pressure spring 5 can ensure that the stepped drive shaft 8 is in a neutral position through the pressure spring seat A3 and the pressure spring seat B6, and the proximity switches A, B10, and 13 have no signal output.
