Anti-blocking type electric valve used for Chinese wolfberry collecting device

Abstract

In order to solve the problems in the prior art, the invention provides an anti-blocking electric valve used for a Chinese wolfberry anti-blocking and isolating type collecting device. The anti-blocking type electric valve comprises an electric valve body, a fruit inlet, a fruit outlet and a valve plate, wherein the valve plate is arranged on a pipeline between the fruit inlet and the fruit outlet. The valve plate is a circular plate matched with the pipeline. A circular valve plate frame is arranged at the peripheral outer side of the valve plate, and a plurality of circular holes are formed in the valve plate frame. The anti-blocking type electric valve further comprises a shrinkage connecting rod which penetrates through the circular holes; one end, facing towards the valve plate, of the shrinkage connecting rod is connected with the valve plate through a valve plate spring, so that length regulation, changing along with the pipeline aperture, of the shrinkage connecting rod is realized. By virtue of the anti-blocking type electric valve, continuous collecting and encasing of fruits is realized, and damages which are possibly caused to the fruits in the collecting process are avoided.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a collection device for granular fruits or crops, in particular to an anti-blocking electric valve used in an anti-blocking isolated collection device for wolfberry. Background technique [0002] Lycium barbarum is not only a traditional precious Chinese herbal medicine, but also a nutritional tonic. According to official statistics, in Gansu alone in 2012, the output of wolfberry reached 35,000 tons. Due to the characteristics of high water content and delicate peel of wolfberry fruit when ripe, it is easy to damage when collecting; if damage occurs, it will not only affect its appearance and color, but also reduce its medicinal value. Therefore, it is necessary to adopt a flexible collection method to pick off the wolfberry fruit together with the fruit handle. At present, there is no commercialized wolfberry automatic collecting device on the market, and the...

Problems solved by technology

The problems in the wolfberry picking machine described in this application are: (1) the leaves blown out by the dual-channel fan often remain in the collection box and cannot be completely separated from the wolfberry fruit; (2) when the collection box is full of wolfberry fruit, it needs to Manually replace the collection box after stopping the machine; (3) when the wolfberry fruit enters the collection box, the collision between the wolfberry fruit and the collection box often causes the damage of the wolfberry fruit

The problems of the Lycium barbarum picking machine described in this application: (1) While using the negative pressure to collect the fruit, the high-pressure airflow is blown outwards to discharge the leaves near the fruit, which is easy to produce turbulent flow, so that the position of the Lycium barbarum fruit is constantly Shaking increases the difficulty of picking; (2) Due to excessive pressure, the fruit will be directly attached to the gas port on the air amplifier; if the leaves are sucked in, it will directly block the air amplifier, causing the machine to not work properly; (3) Fruit collection box Too small for continuous operation

That is: when the electric valve is closed, if there are still goji berries passing through the electric valve at this time, the goji berries are easily squeezed by the valve plate when they are out of date, causing the fruit to burst; A gap is formed between the valve body of the electric valve, which affects the sealing performance of the electric valve and causes air leakage in the entire collection device, thereby greatly reducing the collection efficiency of wolfberry
