Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a cutting platform guard of a corn harvester. Background Art

[0002] The corn harvester is the core part of the corn harvester, which mainly plays the role of picking and transporting ears. The corn harvester header cover is used to cover the transmission parts and form a conveying channel with the adjacent shield to ensure that the corn cobs enter the next conveying system smoothly. At present, the side shield of the corn header adopts a semi-closed form. Due to the harsh working environment, dust and debris can easily enter the transmission system during work, accelerating the wear of the system. When the system has problems, it is difficult to observe, which eventually leads to damage to the transmission system and affects normal work.

[0003] CN 206533747 U discloses a corn harvester header shield, comprising a shield shell, wherein the shield shell is fixedly mounted on the side wall of the header of the corn harvester to form a fully enclosed structure. The corn harvester header shield is fixed to the header side wall by bolts and nuts; the shield and the corn harvester header side wall form a closed space, the header transmission system works in the closed space, and the header transmission system status can be observed through an observation panel on the shield shell.

[0004] However, when the harvester is working, the lubricating oil of the transmission system is easy to splash onto the inner surface of the observation window, and the user cannot wipe the inner surface of the observation window, which affects the user's observation of the transmission system status through the observation panel. In addition, the observation panel is exposed and installed on the side of the shield shell. Since the strength of the observation panel itself is relatively fragile, it is easy to break, which affects the normal use of the shield. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, the utility model provides a corn harvester header guard.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a corn harvester header guard, comprising a guard body, an observation window is opened on the side wall of the guard body, an observation plate is fixedly installed on the inner wall of the guard body, the observation plate is arranged at the observation window, a mounting seat is provided on the side of the observation plate, a scraper is movably installed on the mounting seat, a groove is provided on the outer side wall of the guard body, a dialing platform for controlling the movement of the scraper is movably installed in the groove, two groups of guide plates are fixedly installed on the outer side wall of the guard body, the two groups of guide plates are symmetrically arranged on the upper and lower sides of the observation window, and a protective cover is movably installed between the two groups of guide plates.

[0007] Furthermore, the mounting seat is fixedly mounted on the shield body, a T-shaped groove is provided on the mounting seat, the scraper is slidably mounted in the T-shaped groove, the scraper is abutted against the observation plate, a connecting rod is provided at one end of the scraper away from the mounting seat, and the dialing platform is fixedly mounted on the end of the connecting rod.

[0008] Furthermore, the two groups of guide plates are of Z-shaped structure, and a clamping platform corresponding to the guide plate is provided on the side wall of the protective cover, a fastening bolt is installed on the left end of the clamping platform, and a threaded hole matching the fastening bolt is provided on the left side of the observation window.

[0009] Furthermore, anti-fall-off platforms are provided at both ends of the guide plate.

DETAILED DESCRIPTION

[0022] In order to more clearly illustrate the technical solution of the utility model, the utility model is further described below in conjunction with the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0023] according to Figure 1-6 As shown, a corn harvester header guard comprises a guard body 1, an observation window 11 is opened on the side wall of the guard body 1, an observation plate 2 is fixedly installed on the inner wall of the guard body 1 by bolts, the observation plate 2 is arranged at the observation window 11, a mounting seat 3 is provided on the side of the observation plate 2, a scraper 4 is movably installed on the mounting seat 3, a groove 12 is provided on the outer wall of the guard body 1, a dialing platform 5 for controlling the movement of the scraper 4 is movably installed in the groove 12, two groups of guide plates 6 are fixedly installed on the outer wall of the guard body 1 by bolts, the two groups of guide plates 6 are symmetrically arranged on the upper and lower sides of the observation window 11, and a protective cover 7 is movably installed between the two groups of guide plates 6.

[0024] In this embodiment, the mounting seat 3 is fixedly mounted on the shield body 1 by welding, and a T-shaped groove 31 is opened on the mounting seat 3. The scraper 4 is slidably installed in the T-shaped groove 31. The scraper 4 abuts against the observation plate 2. A connecting rod 41 is provided at the end of the scraper 4 away from the mounting seat 3. The end of the connecting rod 41 passes through the groove 12. The dialing platform 5 is fixedly mounted on the end of the connecting rod 41. The user pulls the dialing platform 5 to make the scraper 4 slide along the T-shaped groove 31, so that the oil stains attached to the inner side of the observation plate 2 are scraped off by the scraper 4.

[0025] In this embodiment, the two groups of guide plates 6 are of a Z-shaped structure, and a clamping platform 71 corresponding to the guide plate 6 is provided on the side wall of the protective cover 7. The protective cover 7 is slidably installed between the two groups of guide plates 6 through the clamping platform 71. The left end of the clamping platform 71 is installed with a fastening bolt 8 through threaded cooperation. A threaded hole 13 matching with the fastening bolt 8 is provided on the left side of the observation window 11. By fitting the fastening bolt 8 into the threaded hole 13, the position of the protective cover 7 is fixed.

[0026] In this embodiment, anti-detachment platforms 61 are provided at both ends of the guide plate 6 . The length of the anti-detachment platforms 61 is greater than the width of the clamping platforms 71 . The anti-detachment platforms 61 prevent the protective cover 7 from detaching from the guide plate 6 .

[0027] In this embodiment, a guardrail 9 welded thereto is fixedly installed in the observation window 11 , and the observation window 11 is provided with multiple protections by means of the guardrail 9 and the protective cover 7 .

[0028] When the utility model is in use, the shield body 1 is installed on the side wall of the cutting platform of the corn harvester by bolts. When the transmission system needs to be checked, the user loosens the fastening bolts 8, and then pulls the shield 7 to the right to reveal the observation window 11, so that the user can observe the inside of the shield body 1 through the observation plate 2. When the oil stains attached to the inner side of the observation plate 2 greatly affect the observation, the user pulls the dial 5 in the groove 12, and scrapes off the oil stains attached to the inner side of the observation plate 2 by the scraper 4, so that the observation plate can be cleaned without disassembling the shield body. After the inspection is completed, the user resets the shield 7, and positions the shield 7 by fastening the bolts 8, and protects the observation plate 2 by the shield 7.
