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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a harvester elevator housing. (Refer to...) Figure 2 and Figure 3 A harvester elevator housing includes a top shell 1, a bottom shell 2, and a front shell 3. A connecting mechanism 4 is provided on the surface of the top shell 1. Fixing frames 5 are fixedly installed on the surfaces of both the top shell 1 and the bottom shell 2. A fixing block 51 is fixedly installed on the surface of the front shell 3. The surface of the fixing block 51 is slidably connected to the inner cavity of the fixing frame 5. A rod 52 is inserted into the top of the fixing frame 5. The lower end of the rod 52 passes through the fixing frame 5 and is slidably connected to the fixing frame 5. A slot 53 is provided on the surface of the fixing block 51. The lower end of the rod 52 is inserted into the inside of the slot 53. A positioning component 54 is provided inside the fixing frame 5. The positioning component 54 is used in conjunction with the rod 52.

[0026] The connecting mechanism 4 includes a connecting frame 41 fixedly installed on the surface of the top shell 1, a connecting block 42 fixedly installed on the surface of the bottom shell 2, the surface of the connecting block 42 being slidably connected to the inner cavity of the connecting frame 41, a card plate 43 inserted into the top of the connecting frame 41, the lower end of the card plate 43 penetrating through the connecting frame 41 and slidably connected to the connecting frame 41, a slot 4301 opened on the surface of the connecting block 42, the lower end of the card plate 43 being inserted into the inside of the slot 4301, a bracket 44 fixedly installed on the surface of the connecting frame 41, a pull rod 45 slidably connected inside the bracket 44, one end of the pull rod 45 being fixedly connected to the card plate 43, and a support component 46 provided on the surface of the connecting frame 41, the support component 46 being used in conjunction with the pull rod 45;

[0027] When assembling the elevator housing, the connecting block 42 is slid into the interior of the connecting frame 41, and the clamping plate 43 is pressed towards the slot 4301 by the pull rod 45 so that the clamping plate 43 is inserted into the interior of the slot 4301. Then, the position of the pull rod 45 is stabilized by the positioning component 54, thereby fixing the connecting block 42 inside the connecting frame 41, thus completing the assembly of the top shell 1 and the bottom shell 2. Then, the front shell 3 is fitted onto one side of the top shell 1 and the bottom shell 2, and the fixing block 51 is inserted into the interior of the fixing frame 5. Subsequently, the insertion rod 52 is inserted into the interior of the slot 53, and the insertion rod 52 is positioned by the positioning component 54 to stabilize the fixing block 51 in the fixing frame 5, thereby stabilizing the position of the front shell 3 and completing the assembly of the elevator housing.

[0028] Reference Figure 3 and Figure 4The support assembly 46 includes a sleeve 4601 fixedly mounted on the surface of the connecting frame 41. A support rod 4603 extends through the top of the pull rod 45, and the surface of the support rod 4603 is slidably connected to the pull rod 45. The lower end of the support rod 4603 extends into the interior of the sleeve 4601 and is slidably connected to the inner cavity of the sleeve 4601. A protrusion 4604 is fixedly mounted on the lower end of the surface of the support rod 4603. A groove 4602 is formed on the surface of the sleeve 4601, and the protrusion 4604... The surface of the support rod 4603 is slidably connected to the inner cavity of the slide groove 4602. A first opening 4605 is provided at the bottom of the inner wall of the slide groove 4602, which is used in conjunction with the protrusion 4604. A threaded sleeve 4606 is threadedly connected to the upper end of the surface of the support rod 4603, and the bottom of the threaded sleeve 4606 is in contact with the top of the pull rod 45. A second opening 4607 is provided at the upper end of the inner wall of the slide groove 4602, which is used in conjunction with the protrusion 4604. After the clamping plate 43 is pressed down by the pull rod 45, the support rod 4603 slides inside the sleeve 4601, and the protrusion 4604 slides from the slide groove 4602 into the first opening 4605. Then, the threaded sleeve 4606 is rotated to lock the support rod 4603, so that the support component 46 supports the pull rod 45 and prevents the pull rod 45 from moving upward and affecting the position of the clamping plate 43. When it is necessary to pull the pull rod 45 upward, the support component 46 supports the pull rod 45. When moving, loosen the threaded sleeve 4606, then rotate the support rod 4603 so that the protrusion 4604 slides from the first opening 4605 into the interior of the slide groove 4602. Pull the support rod 4603 upward and rotate the support rod 4603 so that the protrusion 4604 slides from the slide groove 4602 into the interior of the second opening 4607, so that the support rod 4603 no longer supports the pull rod 45. Then the pull rod 45 can be pulled upward to separate the clamping plate 43 from the clamping groove 4301.

[0029] Reference Figure 2 and Figure 5 The positioning component 54 includes a positioning rod 5401, which passes through the fixing frame 5 and is slidably connected to the fixing frame 5. A support block 5402 is fixedly installed on the surface of the positioning rod 5401. A spring 5403 is fixedly installed inside the fixing frame 5. The inner cavity of the spring 5403 is slidably connected to the surface of the positioning rod 5401. One end of the spring 5403 is fixedly connected to the support block 5402. A positioning groove 5404 is opened on the surface of the insertion rod 52. One end of the positioning rod 5401 extends into the interior of the positioning groove 5404 and is slidably connected to the inner cavity of the positioning groove 5404. Before inserting the insertion rod 52 into the slot 53, the positioning rod 5401 is pulled. After inserting the insertion rod 52 into the slot 53, the positioning rod 5401 is released. The supporting force of the spring 5403 causes the support block 5402 to reset. The support block 5402 drives the positioning rod 5401 to reset, so that one end of the positioning rod 5401 is inserted into the interior of the positioning groove 5404, thereby positioning the insertion rod 52.

[0030] Reference Figure 5 The fixing frame 5 has a cavity 5405 inside, and a first groove 5406 inside, which is connected to the cavity 5405. A limiting rod 5407 is fixedly installed on the surface of one end of the positioning rod 5401. The limiting rod 5407 works in conjunction with the first groove 5406. When the positioning rod 5401 is pulled, one end of the positioning rod 5401 is pulled into the cavity 5405. At the same time, the limiting rod 5407 can enter the cavity through the first groove 5406. Then, the positioning rod 5401 is rotated so that the limiting rod 5407 fits against the inner wall of the cavity 5405, thereby limiting the position of the positioning rod 5401. This allows the positioning rod 5401 to be released after being pulled apart, thus facilitating the insertion of the insertion rod 52.

[0031] Reference Figure 5 The inner wall of the positioning groove 5404 is provided with a second groove 5408, which works in conjunction with the limiting rod 5407. After the insertion rod 52 is inserted into the slot 53, the positioning rod 5401 is rotated so that the limiting rod 5407 is located in the position of the first groove 5406, so that the cavity 5405 no longer restricts the position of the positioning rod 5401, allowing the positioning rod 5401 to be inserted into the interior of the positioning groove 5404. The second groove 5408 prevents the limiting rod 5407 from affecting the position of the positioning rod 5401, so that the positioning rod 5401 can be smoothly inserted into the interior of the positioning groove 5404.

[0032] Working principle: When assembling the elevator housing, the connecting block 42 is slid into the connecting frame 41, and then the pull rod 45 is used to press the clamping plate 43 towards the clamping groove 4301 so that the clamping plate 43 is inserted into the clamping groove 4301. Then, the support rod 4603 is rotated to separate the protrusion 4604 from the second opening 4607 and enter the sliding groove 4602. Then, the support rod 4603 is pressed down to move the protrusion 4604 to the bottom of the groove. The support rod 4603 is rotated to make the protrusion 4604 enter the first groove 5406. Then, the threaded sleeve 4606 is rotated to make the threaded sleeve 4604 enter the first groove 5406. 606 is tightly attached to the top of the pull rod 45, and thus the support rod 4603, sleeve 4601, first opening 4605, protrusion 4604 and threaded sleeve 4606 support the pull rod 45 to maintain the stability of the pull rod 45 position. The pull rod 45 supports the position of the clamping plate 43 to fix the connecting block 42 inside the connecting frame 41, thereby completing the assembly of the top shell 1 and the bottom shell 2. Then the lifting structure can be installed inside the top shell 1 and the bottom shell 2. After the lifting structure is installed, the front shell 3 is sleeved on one side of the top shell 1 and the bottom shell 2, and the fixing block 51 is inserted. Inside the fixing frame 5, pulling the positioning rod 5401 causes the limiting rod 5407 to enter the cavity 5405 through the first groove 5406. Then, rotating the positioning rod 5401 causes the limiting rod 5407 to abut against the inner wall of the cavity 5405, thus limiting the positioning rod 5401. Next, inserting the insertion rod 52 into the slot 53, and rotating the positioning rod 5401 again moves the limiting rod 5407 to the position of the first groove 5406. The supporting force of the spring 5403 drives the support block 5402 to reset, and the support block 5402 drives the positioning rod 5401 to reset as well. The second groove 5408 prevents the limiting rod 5407 from affecting the movement of the positioning rod 5401, allowing one end of the positioning rod 5401 to be inserted into the positioning groove 5404 to fix the fixing block 51 in the fixing frame 5, thereby completing the assembly of the front shell 3. When it is necessary to disassemble the elevator shell for maintenance, the positioning component 54 is separated from the insertion rod 52, and then the insertion rod 52 is removed to remove the front shell 3. Subsequently, the lifting structure inside the top shell 1 and bottom shell 2 can be removed, and then the top shell 1 and bottom shell 2 can be removed and separated by the connecting mechanism 4.

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.
