Description

Technical Field

[0001] The utility model relates to the technical field of agricultural and animal husbandry machinery, in particular to a picking and flinging knife device of a straw round bale baler. Background Art

[0002] A straw round bale baler is a mechanical device used to compress straw and tie it into round bales. This equipment plays a very important role in agricultural production. It can effectively collect and organize scattered straw for subsequent storage, transportation and utilization.

[0003] Traditional straw processing methods are mostly manual collection or simple mechanical picking. These methods are not only inefficient, but also labor-intensive, and it is difficult to meet the large-scale and mechanized production needs of modern agriculture. Although the existing straw picking and baling machines have improved the picking efficiency to a certain extent, there are still some shortcomings. For example, the blades of the blade-throwing devices of some existing straw round balers are designed in a straight line. When cutting and picking up straw, the blades with a straight line design may not be effectively cut due to the small contact area. At the same time, the blades with a straight line design may not have a good cutting effect on certain types of straw, such as thicker or wetter straw, thereby reducing the picking efficiency. For this reason, we provide a straw round baler picking and baling device. Utility Model Content

[0004] The utility model aims to provide a picking and flinging blade device for a straw round bale baler to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A picking-up and flinging blade device for a straw round bale baler comprises: a shell, the picking-up and flinging blade device is arranged on the inner side of the shell, a stabilizing plate is welded on the outer side of the shell, and a guide plate is fixed on one side of the shell;

[0007] The picking and throwing knife device includes a fixed plate, a fixed plate is fixed on the outer side of the stabilizing plate, a rotating motor is fixed on the upper side of the fixed plate, a connecting rod is fixed in the output end direction of the rotating motor, and a throwing knife component is fixed on one side of the connecting rod.

[0008] The picking and throwing knife device is firmly installed on the inner side of the outer shell through the fixing plate. The rotating motor is fixed on the upper side of the fixing plate to provide power for the entire device. When the rotating motor is started, its output end will drive the connecting rod to rotate. One side of the connecting rod is connected to the throwing knife component, so the rotation of the connecting rod will drive the throwing knife component to rotate.

[0009] Preferably, the blade-flicking component includes a connecting roller 1, a connecting roller 1 is fixed to one side of the connecting rod, a first blade-flicking tool is fixed to the outer side of the connecting roller 1, two groups of spiral blades are fixed to the outer side of the first blade-flicking tool, and several groups of second blades are fixed to the outer sides of the two groups of spiral blades by bolts.

[0011] Preferably, a plurality of groups of the second blades are evenly spaced and arranged on the outside of the spiral sheet, and the second blades are arranged with the curved portion of the spiral sheet in an inclined shape.

[0012] Two groups of spiral blades are fixed on the outside of the first blade. They are arranged in a mirror image and have a spiral structure. The design of the spiral blades helps to gather the straw to the center and improve the picking efficiency. Several groups of second blades are evenly spaced on the outside of the spiral blades. These second blades are arranged with the curved part of the spiral blades and are inclined. This can more effectively cut and pick up the straw during the rotation process.

[0013] Preferably, the first swinging knife comprises a connecting roller 2, a connecting roller 2 is fixed to the outer side of the connecting roller 1, a blade is arranged on the outer side wall of the connecting roller 2, and a plurality of reserved grooves are opened on the blade.

[0014] Preferably, the blades are provided in six groups, and the six groups of blades are arranged in a circular array on the outer side of the connecting roller 2.

[0015] The blade of the first swing knife is provided with a number of reserved grooves. This design can reduce the weight of the blade and improve the rotation efficiency. At the same time, the reserved grooves can also help reduce the friction between the straw and the blade, making the straw easier to pick up.

[0016] Preferably, the guide plate is arranged in a "slope" shape.

[0017] The guide plate fixed on one side of the outer shell plays the role of guiding the flow direction of the straw. Since the guide plate is arranged in a "slope" shape, it can guide the straw to smoothly enter the working area of ​​the picking and flinging knife device, further improving the picking efficiency.

[0018] Compared with the prior art, the utility model provides a picking and flinging knife device for a straw round bale baler, which has the following beneficial effects:

[0019] 1. The utility model drives the blade-flipping component to rotate by a rotating motor. The first blade, spiral blade and second blade on the blade-flipping component work together to achieve efficient picking, cutting and preliminary baling of straw, which greatly improves the efficiency and quality of straw recycling and solves the problem of low picking efficiency in the prior art.

[0020] 2. The reserved groove on the blade of the utility model not only reduces the weight of the blade and improves the rotation efficiency, but also reduces the friction between the straw and the blade, making the straw easier to pick up, which not only improves the work efficiency but also reduces the wear rate of the blade. The design of the spiral blade can effectively gather the straw to the center and improve the picking efficiency. The mirror arrangement and spiral shape structure of the spiral blade also help to increase the grip and stability of the straw. BRIEF DESCRIPTION OF THE DRAWINGS
