Description

Technical Field

[0001] The utility model relates to agricultural machinery technology, in particular to a ridge baler and a picking device thereof. Background Art

[0002] Corn ridge cultivation is a common corn cultivation technology that can effectively increase corn yield and improve quality. It is suitable for various types of soil and different climatic conditions. Straw baling and field removal technology can prevent environmental pollution and reduce pests and diseases, while improving the comprehensive utilization rate of straw, turning waste into treasure and increasing profits.

[0003] The existing drum-type spring-tine picker can only follow the forward direction of the machine. Since the spring-tine cannot follow the horizontal direction, it is difficult to pick up the straw at the bottom of the ridge, resulting in a high missed detection rate. Although the missed detection rate can be reduced by lowering the height of the picker spring-tine from the ground, this method will cause a large number of spring-tine contacts with the top of the ridge to be damaged, increasing the cost of use and cannot be used on a large scale.

[0004] The existing picking method of ridge straw balers is mainly based on hammer claw pickup. The high-speed rotation of the hammer claw generates negative pressure airflow to suck and pick up the straw. A large amount of dust will be mixed in the picking process, and then multiple complex dust removal devices are set up to filter out the dust. Due to the unique dust removal structure and picking method, the operation speed of this method is slow and can only be used for small-scale operations. The manufacturing and use costs of the whole machine are relatively high. The final straw bales still contain a large amount of dust and impurities, which indirectly increases the subsequent use costs and is not conducive to the efficient and sustainable development of the straw industry.
