Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figures 1-5 The illustrated tractor power reversing housing includes a lower housing 1 and an upper housing 2, which are mounted together by bolts. A drive shaft is connected between the lower housing 1 and the upper housing 2. The housing also includes a connecting seat 3, an oil reservoir 5, and a docking unit 6. The connecting seat 3 is mounted on the upper housing 2, and the oil reservoir 5 is disposed inside the connecting seat 3.

[0028] An oil collection seat 7 is provided directly below the lower housing 1, and the oil collection seat 7 is installed through the docking unit 6;

[0029] The docking unit 6 includes a fixed base 61, a positioning base 62, and a connector 63. The fixed base 61 is fixedly connected to the lower part of the lower housing 1. The positioning base 62 and the connector 63 are attached to the fixed base 61. The two connectors 63 are fixed on both sides of the oil collection seat 7, and the connectors 63 cooperate with the positioning base 62 to limit the installation position of the oil collection seat 7.

[0030] When the connector 63 is engaged with the positioning seat 62, the oil collection seat 7 is limited to the insertion position corresponding to the lower housing 1.

[0031] When the connecting parts 63 on both sides of the oil collection seat 7 are attached to the positioning seat 62, the connecting parts 63 can be fixed by installing the positioning seat 62 to the lower housing 1, thereby fixing the oil collection seat 7 in the lower housing 1.

[0032] At this time, the oil collection seat 7 collects impurities such as wear-induced impurities and lubricating oil from the lower housing 1 and upper housing 2. By disassembling the installation of the positioning seat 62 with the lower housing 1, the oil collection seat 7 can move downward under the action of gravity. At this time, the connecting part 63 is not fixed, and the oil collection seat 7 can be pulled outward to collect and clean the impurities in the lower housing 1 and upper housing 2. This effectively avoids the complicated process of disassembling the lower housing 1 and upper housing 2, and at the same time prevents dust from entering the lower housing 1 and upper housing 2.

[0033] The oil reservoir 5 is slidably connected to the inner wall of the connecting seat 3. The oil reservoir 5 has multiple oil leakage holes on its wall. By pushing the oil reservoir 5 to move, the oil reservoir 5 enters the upper box 2. At this time, the lubricating oil in the oil reservoir 5 enters the lower box 1 and the upper box 2 to lubricate the power reversing mechanism in the lower box 1 and the upper box 2. Then, by pulling the oil reservoir 5 into the connecting seat 3, the lubricating oil in the connecting seat 3 enters the oil reservoir 5, which facilitates repeated lubrication of the power reversing mechanism in the lower box 1 and the upper box 2.

[0034] The lower housing 1 is provided with a hole cover 4. By opening the hole cover 4, it is easy to remove the hole cover 4, which facilitates the observation of the power reversing mechanism in the lower housing 1 and the upper housing 2, and effectively observes the wear degree of the power reversing mechanism and the lubrication mechanism.

[0035] Handles 71 are installed on both the front and back of the oil collection seat 7, which makes it easy to pull out and push in the oil collection seat 7.

[0036] Because the oil collecting seat 7 is equipped with a sealing ring that is interference-fitted with the lower housing 1, there is a situation where the oil collecting seat 7 is tightly fitted into the lower housing 1. The oil collecting seat 7 can be moved vertically out of the lower housing 1 by pressing down the handle 71 with both hands.

[0037] A mounting component 65 is fixedly connected to one side of the fixed base 61. A telescopic rod 64 is mounted on the mounting component 65. The telescopic rod 64 contacts the bottom of the positioning base 62 to support the positioning base 62.

[0038] When the positioning seat 62 is not installed with the lower housing 1, under the action of gravity, the positioning seat 62 presses down the telescopic rod 64 to the minimum stroke, and the telescopic rod 64 supports the positioning seat 62. At this time, there is a certain insertion space between the positioning seat 62 and the lower housing 1, which makes it convenient to insert the connecting parts 63 on both sides of the oil collection seat 7, and then install the oil collection seat 7.

[0039] The positioning seat 62 is provided with a positioning groove 621, and the connecting piece 63 is provided with a corresponding docking groove 631. When the positioning groove 621 and the docking groove 631 are engaged, the relative position of the oil collecting seat 7 and the lower box 1 in the horizontal direction is restricted.

[0040] By sliding the connector 63 along the positioning seat 62, as the connector 63 gradually slides in, the mating groove 631 mates with the positioning groove 621. At this time, the connector 63 and the positioning seat 62 are in contact, thus completing the limitation of the connector 63 and the oil collection seat 7.

[0041] Both ends of the positioning seat 62 are provided with connecting blocks 622, and the two sides of the connector 63 are provided with mounting blocks 632 respectively. The bottom of the lower housing 1 is provided with four mounting seats 11 corresponding to the connecting blocks 622.

[0042] When the docking groove 631 docks with the positioning groove 621, the connecting block 622 and the mounting block 632 fit together. Since the connecting block 622 corresponds to the mounting base 11, the connecting block 622, the mounting block 632 and the mounting base 11 correspond to each other.

[0043] It can be connected to the mounting base 11 by connecting bolts and the positioning base 62 is pressed, pushing the connecting piece 63 to move and press and fix it at the bottom of the lower box 1. With the movement of the connecting piece 63, the oil collection seat 7 is inserted into the lower box 1 for oil collection.

[0044] The connecting block 622 and the mounting block 632 are fixed by connecting bolts. The connecting bolts are threadedly connected to the mounting base 11, so that the positioning base 62 and the connecting piece 63 are firmly attached to the bottom of the lower box 1, and the oil collection base 7 is vertically inserted into the lower box 1.

[0045] When it is necessary to disassemble the oil collection seat 7, first stop the tractor and ensure that the power reversing box is stationary. At this time, loosen the fastening connection, and the operator uses tools to loosen the connecting bolts that fasten the positioning seat 62 and the connecting piece 63 to the mounting seat 11 at the bottom of the lower box 1.

[0046] As the connecting bolts loosen, the connector 63 separates from the mounting base 11. Under the action of gravity, the telescopic rod 64 extends and retracts, causing the positioning base 62 and the connector 63 to move downwards, and the oil collection base 7 to move downwards, thus releasing the restriction on the oil collection base 7.

[0047] At this time, the telescopic rod 64 extends and retracts, providing upward movement space and guidance for the positioning seat 62, so that the oil collection seat 7 can be pulled out from the positioning seat 62 to avoid jamming. The operator holds the handle 71 on the front of the oil collection seat 7 and pulls the oil collection seat 7 to move it. At this time, the connecting piece 63 slides outward along the positioning seat 62, and the oil collection seat 7 can be taken out.

[0048] Thoroughly clean the removed oil collection seat 7 to remove all oil and impurities. Inspect the inside of the housing and the wear of each component. Repair or replace if necessary. Finally, reinstall the oil collection seat 7.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
