Bundling machine for mechanically picking straw rods

Abstract

The invention discloses a bundling machine for mechanically picking up straw rods, which comprises a straw shifting wheel, straw shifting rods, straw blocking frames and an auxiliary straw pressing mechanism, wherein the surface of the straw shifting wheel is provided with mounting heads which are uniformly distributed annularly, and the surfaces of the mounting heads are provided with movably connected straw shifting rods; a torsion spring is arranged at the joint of the straw shifting rods and the mounting heads, one end of the torsion spring is fixedly connected with the straw shifting rods, the other end of the torsion spring is fixedly connected with the mounting heads, a rotating shaft is arranged in the center of the straw shifting wheel, the straw blocking frames is coaxially distributed at the edge of the straw shifting wheel in an arc shape, the auxiliary straw pressing mechanism is arranged on the right side of the straw blocking frame, the auxiliary straw pressing mechanismcomprises a fixing frame, straw pressing rollers and positioning sheets, the straw pressing rollers are uniformly distributed in the fixing frame and are connected with the fixing frame in a slidingway, and the positioning sheets are arranged between the straw pressing rollers. By the aid of the auxiliary straw pressing mechanism, the straws on the surface of the straw shifting rods is conveniently pressed and held, so that the straw shifting rods are prevented from falling off due to the elasticity of the torsion spring, and the stability and efficiency of straw picking are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a baler for mechanized straw picking. Background technique [0002] The baler is suitable for bundling crops so that they can be transported to straw secondary processing enterprises or straw secondary utilization sites, so as to effectively avoid the incineration of existing crop straws. The crop straw baler is mainly divided into two categories: one is a baler that does not include a picking mechanism, which requires manual or external picking mechanisms to transport the crop straw to the baler for baling operations; the other is a baler that does not include a picking mechanism. The baler includes a picking mechanism and is moved by traction equipment. The baler can perform baling operations on-line while picking up straw.

Problems solved by technology

[0003] At present, the existing straw picking and bundling machines in the market rely on the rotating grass wheel to drive the grass pole to pick up the grass poles, and a torsion spring structure is sleeved at the joint between the grass pole and the grass wheel. The weight of the pole is light and the stroke of this kind of picking structure is too large. When the grass pole leaves the ground, it will shake due to the torsion spring structure, which will easily cause the grass pole to fall easily, resulting in unclean picking and reducing the impact on the grass pole. The picking efficiency
