[0043] Some embodiments of the utility model will be described in detail below in combination with the drawings. In the case of no conflict, the following examples and features in the examples can be combined with each other.

[0044] Example 1

[0045] The embodiment provides a cutter assembly for semi-feed combine harvester, comprising:

[0046] The fixed knife plate body 1 is of segmented structure, and comprises a plurality of fixed knife plates 101 connected in sequence, and the adjacent two fixed knife plates 101 are detachably connected;

[0047] The left cutter assembly 2 is arranged in the left side area of the fixed knife plate body 1;

[0048] The right cutter assembly 3 is arranged in the right side area of the fixed knife plate body 1.

[0049] The fixed knife plate body 1 is of a segmented structure and is sequentially spliced by at least two fixed knife plates 101. The segmented design of the fixed knife plate body 1 reduces the length of a single fixed knife plate 101, facilitates the packaging and transportation of the fixed knife plate 101, and improves the structural strength of the knife plate due to the reduced length of the fixed knife plate 101.

[0050] Embodiment 2

[0051] In the prior art, in addition to the technical problems mentioned in the background art, there are the following problems: Figures 1-3 In the prior art, a single fixed blade 10 is riveted on the same fixed knife plate 101 by two rivets 4, and a plurality of moving blades and a left moving knife rod and a cutter driving plate are riveted into a left moving knife rod rivet by rivets 4, and a plurality of moving blades and a right moving knife rod and a cutter driving plate are riveted into a right moving knife rod rivet by rivets 4. The single fixed blade 10 of the single-board double-moving cutter uses 2 rivets 4 for riveting (as shown in Figure 2 When subjected to vertical impact, the rivets 4 are prone to loosening and breaking. The intermediate fixed blade 5 is riveted on the fixed knife plate 101, and due to the existence of a 4-6 mm gap at the end of the left and right moving knife rods when they move horizontally, the intermediate fixed blade 5 is prone to accumulate grass clippings and soil during operation, which enters the gap between the moving and fixed blades 10 to cause the blades to diverge, reducing the cutting effect. With the increase in the number of rows and the increase in the width of the cutter table, the length of the cutter is correspondingly increased, and a single fixed knife plate 101 is prone to bending and deformation, which is not convenient for transportation, and the cost of replacing a new cutter is high when damaged.

[0052] To this end, referring to Figures 4-7 The embodiment provides a cutter assembly for a semi-feed combine harvester, which comprises:

[0053] A fixed knife plate body 1, which is of a segmented structure and comprises a plurality of fixed knife plates 101 connected in sequence, and adjacent two fixed knife plates 101 are detachably connected;

[0054] A left cutter assembly 2 arranged at a left side region of the fixed knife plate body 1;

[0055] A right cutter assembly 3 arranged at a right side region of the fixed knife plate body 1.

[0056] Specifically, the fixed knife plate body 1 comprises two fixed knife plates 101, which are respectively arranged at the left side region and the right side region of the fixed knife plate body 1, and the two fixed knife plates 101 are fixedly connected by a connecting plate 11.

[0057] The left cutter assembly 2 is arranged on the left fixed knife plate 101, and the right cutter assembly 3 is arranged on the right fixed knife plate 101.

[0058] The left cutter assembly 2 and the right cutter assembly 3 are structurally identical, each comprising a fixed cutter riveting and a moving cutter riveting, the fixed cutter riveting comprising a plurality of fixed cutter blades 10 (the structure of the left cutter assembly 2 and the right cutter assembly 3 is prior art, which will not be described here).

[0059] Each fixed cutter blade 10 of the fixed cutter riveting is connected and fixed to the fixed cutter plate 101 by a plurality of rivets 4 or a plurality of (three or more) bolts.

[0060] In this embodiment, the fixed cutter plate 101 is provided with a protruding portion 102 corresponding to the position of the fixed cutter blade 10 (as shown in Figure 6 Each fixed cutter blade 10 is connected and fixed to the fixed cutter plate 101 and the protruding portion 102 by a plurality of rivets 4.

[0061] Preferably, each fixed cutter blade 10 is connected and fixed to the fixed cutter plate 101 and the protruding portion 102 by three rivets 4, which are distributed in an equilateral triangle on the fixed cutter plate 101 and the protruding portion 102, and are symmetrically designed on the left and right to ensure structural stability, as shown in Figure 6 The fixed cutter blade 10 is riveted to the fixed cutter plate 101 by three rivets 4, which can increase the riveting strength, improve the vertical impact torque that the fixed cutter blade 10 can withstand, and reduce the phenomenon of easy loosening and breaking of the rivets 4 of the fixed cutter blade 10.

[0062] The cutter assembly further comprises a middle fixed cutter blade 5 arranged in the middle of the fixed cutter plate main body 1, the middle fixed cutter blade 5 comprising two symmetrically arranged half fixed cutter blades 501, the two half fixed cutter blades 501 are respectively arranged in the fixed cutter plate 101 by a blade press 6, and the middle fixed cutter blade 5 exceeds the fixed cutter blade 10.

[0063] Preferably, the fixed cutter blade 10 is divided into two symmetric half fixed cutter blades 501, i.e. the middle fixed cutter blade 5 is formed by splitting the fixed cutter blade 10 in half. Such a structural design of the middle fixed cutter blade 5 can solve the problem of grass and soil accumulation on the middle fixed cutter blade 5. The middle fixed cutter blade 5 is combined with the blade press 6, and the middle fixed cutter blade 5 is designed as a half cutter structure (i.e. half fixed cutter blade 501), and two symmetrically arranged blade presses 6, so that the middle fixed cutter blade 5 is above the moving cutter blade, and there is a 4-6mm gap at the end of the left moving cutter rod and the right moving cutter rod when they move horizontally, so that the grass and soil can fall off smoothly and will not accumulate to cause blade wear and tear.

[0064] It should be noted that the blade press 6 (also known as a blade holder) generally refers to a device used to fix and adjust tools (such as cutting blades) during mechanical processing or metal plate processing. Its main function is to ensure the stability and accuracy of the tool during processing by applying a certain pressure.

[0065] In the embodiment, the left part and the right part of the cutter plate body 1 are further respectively provided with middle fixing frames 7.

[0066] The left and right ends of the cutter plate body 1 are further respectively provided with left fixing frames 8 and right fixing frames 9.

[0071] 2. Three rivets 4 are used to rivet the cutter blade 10 to the cutter plate 101, so that the riveting strength is increased, the impact moment in the vertical direction that the cutter blade 10 can withstand is improved, and the rivets 4 of the cutter blade 10 are less likely to loosen and break.

[0072] 3. The middle cutter blade 5 is arranged above the moving cutter blade and combined with the blade sharpener 6, so that grass clippings and soil are less likely to accumulate and the cutter blade is less likely to wear and crack.
