[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.
[0023] like Figures 1 to 5 This embodiment provides a bulldozer cover assembly device, comprising a left cover 1 and a right cover 2. The left cover 1 is mounted on the left side of the bulldozer wing, and the right cover 2 is mounted on the right side of the bulldozer wing. The left cover 1 comprises a left top plate 3, a left main plate 4, and a left connecting plate 6, all formed by bending. The left top plate 3, the left main plate 4, and the left slanted plate 5 are interconnected to form a left protective chamber. Specifically, the left main plate 4 is connected to the outer side of the left top plate 3, the left slanted plate 5 is connected to the front end of the left top plate 3, and the left main plate 4 and the left slanted plate 5 are interconnected. The bottoms of the left top plate 3, the left main plate 4, and the left slanted plate 5 are all vertically connected to the left connecting plate 6. Bolts pass through the left connecting plate 6, presumably on the left side of the wing, to achieve a removable connection with the wing. A left switch door 7 is provided on each of the left top plate 3, the left main plate 4, and the left slanted plate 5. An electrical integration mounting plate 8 is vertically mounted within the left protective chamber, and a battery mounting plate 9 is mounted on one side of the motor integration mounting plate. The bulldozer's electronic components and other components are mounted on the electrical integration mounting plate 8, located within the left cover. This not only facilitates the operator's timely adjustment of component assembly positions, but also optimizes the use of space within the left chamber, ensuring orderly installation and ease of subsequent inspection, replacement, or maintenance. Similarly, the battery mounting plate 9 facilitates battery installation and placement, enhancing the convenience of bulldozer operation.
[0024] The right cover 2 includes a right top plate 10, a right main plate 11, a right oblique plate 12 and a right connecting plate 13, which are integrally bent. This part is configured in the same manner as the left cover 1. Therefore, the right top plate 10, the right main plate 11 and the right oblique plate 12 are interconnected to form a right protective chamber. The right connecting plate 13 is vertically arranged at the bottom of the right top plate 10, the right main plate 11 and the right oblique plate 12. A right switch door 14 is respectively provided on the right top plate 10, the right main plate 11 and the right oblique plate 12; when the right cover 2 is installed on the right side of the wing plate, the right connecting plate 13 is detachably connected and fixed to the right side of the excavator wing plate by means of bolts passing through, thereby forming a connection.
[0025] In some embodiments, the left switch door 7 on the left top plate 3 is screwed to the left top plate 3 via bolts. During use, the bolts are tightened to open and close the door. The left switch door 7 on the left inclined plate 5 is hingedly connected to the left inclined plate 5 on its upper side, and its lower side is connected to the left inclined plate 5 using an existing switch device for opening and closing. The left switch door 7 on the left main plate 4 is hingedly connected to the left main plate 4 on one side, and its other side is connected to the left main plate 4 using an existing switch device for opening and closing. Similarly, the right switch doors 14 on the right cover 2 are installed in the same manner as the left switch door 7 on the left cover 1. Corresponding left and right switch doors 7, 14 are provided in different directions on the left and right cover 1, 2. This allows operators to conveniently open the left and / or right switch doors 7, 14, located in the corresponding directions and observe the status of components within the left and right protective chambers from different perspectives, thereby facilitating inspection, repair, or replacement of components.
[0026] In some embodiments, as Figure 3 and Figure 5 A left rib 15 extends vertically inward between the left main plate 4 and the left slanted plate 5; a right rib 16 extends vertically inward between the right main plate 11 and the right slanted plate 12. The left rib 15 and the right rib 16 provide support strength for the left and right cover shells 1 and 2, respectively, facilitating the safety and protection of the corresponding internal components of the bulldozer.
[0027] In some embodiments, as Figure 4 A U-shaped groove 17 extending from the refueling port of the hydraulic oil tank is reserved above the right switch door 14 on the right top plate 10 to facilitate the installation of the hydraulic oil tank.
[0028] In some embodiments, as Figure 3 and Figure 4A left sealing strip 18 is installed on the left top plate 3 and left sloping plate 5 on the side where the left cover 1 contacts the bulldozer wing. When the left cover 1 is installed on the left side of the wing, the left sealing strip 18 seals the left cover 1 and the left side of the wing. A right sealing strip 19 is installed on the right top plate 10 and right sloping plate 12 on the side where the right cover 2 contacts the bulldozer wing. When the right cover 2 is installed on the right side of the wing, the right sealing strip 19 seals the right cover 2 and the right side of the wing. The left and right sealing strips 18 and 19 effectively improve the sealing between the left and right cover 1 and 2 and the wing.
[0029] In some embodiments, as Figure 3 A first mounting and fixing hole 20 is provided on the electrical integrated mounting plate 8 to facilitate the installation and fixing of the pre-installed central electrical box machine harness.
[0030] In some implementations, such as Figure 3 The battery mounting plate 9 comprises a horizontal plate 21, a vertical plate 22, and a retaining plate 23. The horizontal plate 21 is mounted on the left connecting plate 6, and the vertical plate 22 is vertically connected to the horizontal plate 21. A threaded rod 24 has one end fixed to the horizontal plate 21, and the other end passes through the retaining plate 23 and is screwed onto a nut 25. During use, the battery is placed on the horizontal plate 21, and the retaining plate 23 is adjusted to rest against the upper end of the battery. The nut 25 is rotated downward relative to the threads, causing it to rest against the retaining plate 23, thereby securing the battery.
[0031] Optional, such as Figure 3 A through-hole 26 is provided on the vertical plate 22. This through-hole 26 reduces the overall weight of the battery mounting plate 9 and facilitates the connection of the battery wiring harness. Two avoidance holes 27 are provided on either side of the through-hole 26 to reduce interference and avoid the fixing points of the battery mounting plate 9.
