[0001] The present application relates to the field of agricultural machinery, in particular to a mudguard of an agricultural machine. BACKGROUND

[0002] The agricultural machine is a kind of agricultural machinery, which has the characteristics of new type and intelligence, and has multiple functions, and can complete various operations such as rotary tillage, ditching, cultivation and weeding by replacing different tools.

[0003] At present, in order to block the mud and stones flying up during the working process of the agricultural machine and improve the safety of the operator, mudguards are usually installed on both sides of the agricultural machine to block the mud and stones flying up. However, when the agricultural machine is used in narrow areas such as mountainous areas, the width of some areas is narrow, and the mudguards extending from both sides of the agricultural machine will cause difficulty in passing through the agricultural machine. If the width of the mudguard is reduced, the protection effect will be reduced, and thus it is difficult to balance the passing ability and the protection effect when the agricultural machine is used in narrow areas such as mountainous areas. CONTENT OF THE UTILITY MODEL

[0007] By adopting the above technical scheme, when the agricultural machine passes through narrow areas, the extension plate is driven to be close to the support plate, and then the positioning assembly is used to position the extension plate, so as to shorten the extension length of the extension plate, improve the passing ability of the agricultural machine, and when the agricultural machine normally walks and works, the extension plate is driven to be away from the support plate, and then the positioning assembly is used to position the extension plate, so as to increase the extension length of the extension plate and improve the protection effect of the extension plate. Thus, the problem that the passing ability and the protection effect are difficult to balance when the agricultural machine is used in narrow areas such as mountainous areas is improved.

[0008] Optionally, the positioning assembly comprises a telescopic rod, the telescopic rod is arranged on the extension plate, the telescopic rod is connected with the agricultural machine, and the length of the telescopic rod is telescopic.

[0009] By adopting the technical scheme, the length of the telescopic rod is driven to be telescopic, so that the extension plate is driven to be away from the support plate or close to the support plate, the position of the extension plate is adjusted and the extension plate is positioned.

[0010] Optionally, the telescopic rod comprises a sleeve, a sliding rod and a driving member, the sleeve is arranged on the agricultural machine, the sliding rod is slidingly arranged in the sleeve, the sliding rod is connected with the extension plate, and the driving member is arranged on the sleeve and is used for positioning the sliding rod.

[0011] By adopting the technical scheme, the length of the telescopic rod is driven to be telescopic, so that the extension plate is driven to be away from the support plate or close to the support plate, the position of the extension plate is adjusted and the extension plate is positioned.

[0012] Optionally, the driving member comprises a driving screw, the driving screw is rotationally arranged on the sleeve and is threadedly connected with the sliding rod.

[0013] By adopting the technical scheme, the length of the telescopic rod is driven to be telescopic, so that the extension plate is driven to be away from the support plate or close to the support plate, the position of the extension plate is adjusted and the extension plate is positioned.

[0014] Optionally, one end of the sliding rod slidingly arranged in the sleeve is provided with an anti-disengagement block, and a cross-sectional dimension of the anti-disengagement block is greater than an opening dimension of an opening of the sleeve.

[0015] By adopting the technical scheme, when the sliding rod moves away from the sleeve and is about to disengage from the sleeve, the anti-disengagement block abuts against the opening of the sleeve, so as to block the sliding rod from disengaging from the sleeve, and the possibility of the sliding rod moving out of the sleeve when the telescopic rod is elongated is reduced.

[0016] Optionally, the support plate is provided with a support frame, and the support frame is arranged on the agricultural machine.

[0017] By adopting the technical scheme, the support frame supports the support plate, and the stability of the support plate is improved.

[0018] Optionally, the support frame is boltedly connected with the support plate and the agricultural machine.

[0019] By adopting the technical scheme, the support frame is connected with the agricultural machine through bolts, and then the support plate is connected with the support frame through bolts, so that the support plate and the support frame are conveniently assembled and disassembled.

[0020] Optionally, both sides of the support plate and the extension plate are downwardly bent.

[0021] By adopting the technical scheme, the support plate and the extension plate with the side edges being downwardly bent can better block the rolled-up soil and stones, and the protection effect of the support plate and the extension plate is improved.

[0022] To sum up, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When the agricultural machine passes through the narrow terrain area, the extension plate is shortened in length, which improves the passability of the agricultural machine. When the agricultural machine normally walks and works, the extension plate is lengthened in length, which improves the protection effect of the extension plate, and solves the problem that the passability and protection effect are difficult to be considered when the agricultural machine is used in the mountain and hilly area with narrow terrain.

[0024] 2. The sliding rod is positioned by the driving member, so that the length of the telescopic rod can be conveniently adjusted, and the subsequent sleeve and sliding rod can also support the extension plate, thereby improving the stability of the extension plate.

[0025] 3. The support frame is connected with the agricultural machine through the bolt, and the support plate is connected with the support frame through the bolt, so that the support plate and the support frame are convenient to assemble and disassemble. BRIEF DESCRIPTION OF DRAWINGS
