Description

TECHNICAL FIELD

[0001] The utility model relates to the field of straw chopping equipment, and particularly relates to a chopper and a harvester. BACKGROUND

[0002] The existing chopper of the semi-feeding harvester is provided with an upper shield at the upper end, as shown in the figure, when the chopper performs the grass cutting function, the upper shield 4' is opened, and the straw falls into the chopper shell 1', and is cut by the front cutting wheel 2' and the rear cutting wheel 3'. Figures 1 to 3 There is a straw guide plate 6' on the shield, which is used to avoid the straw from falling into the rear end of the chopper when there is too much straw; in the actual working process, due to the shortness of the straw guide plate 6', part of the straw will fall into the position of the rear shield 5' at the rear end of the chopper, or accumulate at the position of the straw guide plate 6', which affects the normal work of the chopper.

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and labeled in the drawings can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0035] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0036] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0038] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] like Figure 4 and Figure 5 As shown, this embodiment provides a shredder, including a shredder housing 1, a front cutting wheel 2, and a rear cutting wheel 3, as well as an upper cover 4, which is located on the feed inlet side of the shredder housing 1. Normally, the upper cover 4 can cover the feed inlet of the shredder housing 1 to prevent objects from accidentally entering the shredder and to reduce the space occupied. When in use, it is opened to guide the material in.

[0041] A grass guide plate 6 is provided on the upper cover 4, and the grass guide plate 6 is set at an angle to the upper cover 4; the first end of the grass guide plate 5 is connected to the upper part of the upper cover 4, and the second end of the grass guide plate 6 extends away from the lower part of the upper cover 4.

[0042] And, when the upper shield 4 is opened, the second end of the straw guide plate 6 points to the position where the front cutting wheel 1 and the rear cutting wheel 2 intersect, and the second end of the straw guide plate 6 slightly exceeds the vertical center line of the rear cutting wheel 2.

[0043] With the above structure, the straw guide plate 6 can make the straw more effectively fall into the cutting position of the front and rear cutting wheels, improving the efficiency of straw feeding and cutting; at the same time, the straw guide plate 6 can also reduce the straw falling into the rear shield 5.

[0044] In a preferred embodiment, the straw guide plate 6 is designed in a split type, including a plurality of long strip-shaped sub-plates 61, which are arranged at intervals.

[0045] The split type of the plurality of sub-plates 61 can not only expand the straw guide area, but also reduce the weight, and facilitate the individual replacement of the sub-plates with more wear, which is conducive to improving the service life of the straw guide plate 6.

[0046] In order to facilitate the disassembly and replacement of the sub-plates 61, the sub-plates 61 and the upper shield 4 are connected by bolts or clamps.

[0047] In a preferred embodiment, the sub-plates 61 are made of elastic and wear-resistant materials, such as 65Mn spring steel, nylon or polyurethane.

[0048] Due to the elasticity of the straw guide plate 6, when the straw feeding amount changes, the straw guide plate 6 can effectively adjust the size of the feeding port by itself, for example, when the straw feeding is too much, the straw guide plate 6 can be pressed and bent to expand the feeding port, and when the straw feeding is less, the straw guide plate 6 rebounds under the action of its own elastic force to reduce the size of the feeding port.

[0049] In a preferred embodiment, the angle between the straw guide plate 6 and the upper shield 4 is not more than 45°, and about 30° is preferred. This angle design can ensure the guiding effect and will not affect the falling speed of the material.

[0050] In a preferred embodiment, the distance between adjacent sub-plates is not greater than the width of the sub-plate, so that the straw can be prevented from falling through the gap between the sub-plates.

[0051] Specifically, the width of a single sub-plate 61 is between 3cm-8cm, and the gap between adjacent sub-plates 61 is set to one third to two thirds of the width of the sub-plate.

[0052] In a preferred embodiment, the upper shield 4 and the shredder shell 1 are connected by a hinge, which can facilitate the opening and closing of the upper shield 4.

[0053] In a second aspect, the embodiment also provides a harvester, which includes the shredder.

[0054] The harvester has the advantages of the shredder, which will not be repeated here.

[0055] The preferred embodiments of the present application have been described above with the preferred embodiments, but the present application is not limited to the above examples, and various modifications and changes can be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
