Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a quick-release structure for an external circulation filter element in agricultural machinery and agricultural machinery. Background Technology

[0002] In the field of agricultural machinery, harvesters are the core harvesting equipment, and the reliability of the harvester cab air conditioning directly affects operating efficiency and economic benefits. The external circulation filter, as a key component for purifying the air inside the cab and protecting the air conditioning system, requires regular maintenance and replacement. However, the traditional filter installation structure exposes many problems in the complex farmland operating environment. Currently, the external circulation filter for harvester cab air conditioning is mainly concentrated on the top cover, installed inside the top cover by two plastic bolts and a plastic cap. For maintenance, the two plastic bolts need to be loosened and the plastic cap removed. At this time, the filter is stuck in the top cover groove, and dust will fall out as the plastic cap is opened, which can be inhaled and poses a significant health hazard. When the installation torque of the plastic bolts is too high, special tools are required to remove the plastic cap, which is time-consuming, labor-intensive, inefficient, and repeated disassembly may cause the bolts to fail. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a quick-release structure for the external circulation filter element of agricultural machinery and agricultural machinery, which solves the problems existing in the disassembly and repair of the external circulation filter element of the cab in the prior art, making it safe, time-saving and labor-saving.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A quick-release structure for an external circulation filter element of agricultural machinery includes a top cover body for installation on the top of the cab of agricultural machinery. The top cover body is provided with an upwardly recessed mounting groove. The bottom of the mounting groove is provided with several air outlets. An installation box is inserted into the mounting groove. A filter element is provided in the installation box. The end of the installation box facing the air outlet is provided with an opening. The filter element covers the air outlet. The top cover body is provided with an air inlet communicating with the inside of the installation box. The air inlet is spaced apart from the filter element. The first end of the bottom of the installation box is fastened to the top cover body. The second end of the bottom of the installation box away from the first end is detachably connected to the top cover body through a rotating locking mechanism.

[0005] The beneficial effects of this utility model are: the filter element is placed in the mounting box and then assembled on the top cover body. The filter element can be removed along with the mounting box. During removal, dust on the filter element will not fall down, thus avoiding the impact on the interior environment of the cab and the safety of the operator. Removal can be achieved simply by rotating the locking mechanism, making installation and removal convenient.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a rubber ring is fixedly provided around the end of the filter element facing the air outlet, and the periphery of the opening of the mounting box presses the rubber ring against the bottom of the mounting groove.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the rubber ring can press the filter element against the bottom of the mounting groove and can achieve a seal around the filter element, preventing air from being discharged from the outlet without being filtered.

[0009] Furthermore, the rotating lock cylinder mechanism includes a first rotating shaft, a first mounting hole is provided at the bottom of the mounting box, the first rotating shaft is rotatably disposed in the first mounting hole, a first locking plate is fixedly provided on the end of the first rotating shaft facing the top cover body, a rotating handle is fixedly provided on the end of the first rotating shaft away from the top cover body, and a locking hole is provided on the side wall of the mounting groove for the first locking plate to be rotated and inserted.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: rotating the handle causes the first rotating shaft to rotate, which in turn drives the first locking plate to rotate. When the first locking plate rotates to the point of insertion into the locking hole, it locks the mounting box. When the first rotating shaft is rotated in the opposite direction, the first locking plate disengages from the locking hole, thus enabling the mounting box to be disassembled.

[0011] Furthermore, two first limiting members are fixedly provided on the first rotating shaft, and the two first limiting members respectively rotate to abut against the outer walls of both ends of the first mounting hole.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the setting of the first limiting member can prevent the first rotating shaft from moving in the axial direction.

[0013] Furthermore, a second limiting member and a third limiting member are fixedly provided on the first rotating shaft. The second limiting member is located on the side of the first mounting hole facing the top cover body, and the third limiting member is located on the side of the first mounting hole away from the top cover body. A compression spring is provided between the third limiting member and the mounting box. The compression spring is sleeved on the first rotating shaft, and the two ends of the compression spring abut against the mounting box and the third limiting member, respectively.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by setting a compression spring, after the mounting box is locked, the compression spring applies a force to the first locking plate in a direction away from the top cover body, thus ensuring the stability of the first locking plate when it is locked.

[0015] Furthermore, the second end of the mounting box is provided with an extension plate, the extension plate having a recessed portion that is recessed toward the top cover body, and the rotary lock cylinder mechanism is located within the recessed portion.

[0016] The beneficial effects of adopting the above-mentioned further solution are: by setting the extension plate and the recess, it is convenient to set the rotating lock cylinder mechanism, avoids the rotating lock cylinder mechanism from protruding from the surface of the mounting box, and prevents accidental contact and misoperation.

[0017] Furthermore, the rotating lock cylinder mechanism includes a second rotating shaft, and the top cover body is provided with a second mounting hole. The second mounting hole is located next to the mounting groove. The second rotating shaft is rotatably disposed in the second mounting hole. A second locking plate is fixedly disposed on the second rotating shaft, and the second locking plate abuts against the bottom of the second end of the mounting box.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by rotating the second locking plate, the second locking plate presses against or disengages from the second end of the mounting box, thereby achieving the locking and releasing of the mounting box.

[0019] Furthermore, the second rotating shaft is provided with two fourth limiting members, which respectively rotate to abut against the outer walls of both ends of the second mounting hole.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the fourth limiting member can restrict the axial movement of the second rotating shaft.

[0021] Furthermore, a snap-fit ​​arm is fixedly provided at the first end of the mounting box, and a snap hook is provided at the end of the snap-fit ​​arm away from the mounting box. A snap groove matching the snap hook is provided on the top cover body, and the snap hook is snapped into the snap groove.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the design of the hook and the slot facilitates the fastening of the first end of the installation box with the top cover body.

[0023] This utility model solves the above-mentioned technical problems and also provides an agricultural machinery, including the above-mentioned quick-release structure for the external circulation filter element of agricultural machinery.

[0024] The advantages of adopting the above solution are: the filter element is placed in the mounting box and then assembled on the top cover body.

Detailed Implementation

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] Example 1 like Figures 1 to 5As shown, this embodiment discloses a quick-release structure for an external circulation filter element in agricultural machinery, including a top cover body 1 for installation on the top of the cab of the agricultural machinery. The top cover body 1 has an upwardly recessed mounting groove 2, and the bottom of the mounting groove 2 has several air outlets 3. An installation box 4 is inserted into the mounting groove 2, and a filter element 5 is placed inside the installation box 4. The end of the installation box 4 facing the air outlets 3 has an opening, and the filter element 5 covers the air outlets 3. The top cover body 1 has an air inlet 6 that communicates with the interior of the installation box 4, and the side wall of the installation box 4 has a connection for communicating with the air inlet 6 and the installation box. 4. The internal air intake channel, the air intake port 6 and the filter element 5 are spaced apart. External air is connected to the air intake port 6 through the channel set on the top of the cab, and then enters the mounting box 4 through the air intake port 6 and the air intake channel. After being filtered by the filter element 5, it is discharged from the air outlet 3. The air outlet 3 is connected to the air conditioning air inlet of the cab through the channel. The filtered air enters the cab after passing through the channel and the air conditioning air inlet. The first end of the bottom of the mounting box 4 is fastened to the top cover body 1. The second end of the bottom of the mounting box 4 away from the first end is detachably connected to the top cover body 1 through the rotating lock core mechanism 7.

[0028] A rubber ring 8 is fixedly provided around the end of the filter element 5 facing the air outlet 3, and the periphery of the opening of the mounting box 4 presses the rubber ring 8 against the bottom of the mounting groove 2. The rubber ring 8 can press the filter element 5 against the bottom of the mounting groove 2 and can achieve the sealing of the filter element 5, preventing air from being discharged from the air outlet 3 without being filtered.

[0029] The second end of the mounting box 4 is provided with an extension plate 18, and the extension plate 18 has a recessed portion 19 that is recessed towards the top cover body 1. The rotating lock cylinder mechanism 7 is disposed in the recessed portion 19. By providing the extension plate 18 and the recessed portion 19, the installation of the rotating lock cylinder mechanism 7 is facilitated, and the rotating lock cylinder mechanism 7 is prevented from protruding from the surface of the mounting box 4, thus preventing accidental contact and misoperation.

[0030] The first end of the mounting box 4 is fixedly provided with a fastening arm 24, and the end of the fastening arm 24 away from the mounting box 4 is provided with a hook 25. The top cover body 1 is provided with a fastening groove 26 that matches the hook 25. The hook 25 is fastened in the fastening groove 26. The setting of the hook 25 and the fastening groove 26 can facilitate the fastening of the first end of the mounting box 4 with the top cover body 1.

[0031] In this embodiment, the rotating lock cylinder mechanism 7 includes a first rotating shaft 9. The bottom of the mounting box 4 is provided with a first mounting hole 10. The first rotating shaft 9 is rotatably disposed in the first mounting hole 10. A first locking plate 11 is fixedly disposed on one end of the first rotating shaft 9 facing the top cover body 1. The first locking plate 11 can be fixed to the end of the first rotating shaft 9 by screws, or one end of the first locking plate 11 can be sleeved on the first rotating shaft 9 and then clamped and fixed by two mounting nuts threaded to the first rotating shaft 9. A rotating handle 12 is fixedly disposed on one end of the first rotating shaft 9 away from the top cover body 1. The rotating handle 12 can be threaded to the first rotating shaft 9, or it can be fixedly connected to the first rotating shaft 9 by a common fixing method in the prior art such as a snap pin. The side wall of the mounting groove 2 is provided with a locking hole 13 for the first locking plate 11 to be rotated and inserted. Rotate the handle 12 to make the first rotating shaft 9 rotate, which in turn drives the first locking plate 11 to rotate. When the first locking plate 11 rotates to insert into the locking hole 13, it locks the mounting box 4. When the first rotating shaft 9 is rotated in the opposite direction, the first locking plate 11 disengages from the locking hole 13, and the mounting box 4 can be disassembled.

[0032] Two first limiting members 14 are fixedly provided on the first rotating shaft 9. The two first limiting members 14 rotatably abut against the outer walls of both ends of the first mounting hole 10, and the first limiting members 14 can prevent the first rotating shaft 9 from moving in the axial direction. Specifically, in practical applications, the first limiting member 14 can be a limiting snap ring. The first rotating shaft 9 is provided with a snap ring that matches the limiting snap ring. The two limiting snap rings are correspondingly arranged in the two snap rings. The snap rings restrict the axial movement of the first rotating shaft 9, ensuring that the first rotating shaft 9 can only rotate axially within the first mounting hole 10 and will not move along its length.

[0033] Alternatively, the first limiting member 14 can also be a limiting nut, and the first rotating shaft 9 is provided with an external thread, and the limiting nut is threadedly connected to the first rotating shaft 9.

[0034] Example 2 like Figure 6 As shown, this embodiment makes the following changes based on embodiment one: a second limiting member 15 and a third limiting member 16 are fixedly provided on the first rotating shaft 9. The second limiting member 15 is provided on the side of the first mounting hole 10 facing the top cover body 1, and the third limiting member 16 is provided on the side of the first mounting hole 10 away from the top cover body 1. A compression spring 17 is provided between the third limiting member 16 and the mounting box 4. The compression spring 17 is sleeved on the first rotating shaft 9, and the two ends of the compression spring 17 abut against the mounting box 4 and the third limiting member 16, respectively.

[0035] By setting a compression spring 17, after the mounting box 4 is locked, the compression spring 17 applies a force to the first locking plate 11 in a direction away from the top cover body 1, ensuring the stability of the first locking plate 11 when locked and preventing the mounting box 4 from being loose after the first locking plate 11 is locked.

[0036] Specifically, in practical applications, the second limiting member 15 and the third limiting member 16 can be limiting snap rings. The first rotating shaft 9 is provided with a slot that matches the limiting snap ring. The two limiting snap rings are arranged in the two slots in a one-to-one correspondence. The axial movement of the first rotating shaft 9 is restricted by the snap rings, ensuring that the first rotating shaft 9 can only rotate axially in the first mounting hole 10 and will not move along the length direction.

[0037] Alternatively, the second limiting member 15 and the third limiting member 16 can also be limiting nuts, with the first rotating shaft 9 having external threads, and the limiting nuts being threadedly connected to the first rotating shaft 9.

[0038] Example 3 like Figure 7 As shown, unlike Embodiments 1 and 2 above, the rotating lock cylinder mechanism 7 is mounted on the top cover body 1. Specifically, the rotating lock cylinder mechanism 7 includes a second rotating shaft 20. The top cover body 1 has a second mounting hole 21, which is located next to the mounting groove 2. The second rotating shaft 20 is rotatably disposed within the second mounting hole 21. A second locking plate 22 is fixedly mounted on the second rotating shaft 20, and the second locking plate 22 presses against the bottom of the second end of the mounting box 4. By rotating the second locking plate 22, the second locking plate 22 can press against or disengage from the second end of the mounting box 4, thereby achieving the locking and releasing of the mounting box 4.

[0039] The second rotating shaft 20 is provided with two fourth limiting members 23. The two fourth limiting members 23 respectively rotate and abut against the outer walls of both ends of the second mounting hole 21. The fourth limiting members 23 can restrict the axial movement of the second rotating shaft 20.

[0040] Specifically, in practical applications, the fourth limiting member 23 can be a limiting snap ring. The first rotating shaft 9 is provided with a slot that matches the limiting snap ring. The two limiting snap rings are arranged in the two slots in a one-to-one correspondence. The axial movement of the first rotating shaft 9 is restricted by the snap ring, ensuring that the first rotating shaft 9 can only rotate axially in the first mounting hole 10 and will not move along the length direction.

[0041] Alternatively, the fourth limiting member 23 can also be a limiting nut, with an external thread on the first rotating shaft 9, and the limiting nut is threadedly connected to the first rotating shaft 9.

[0042] Example 4 This embodiment discloses an agricultural machinery, including the quick-release structure for the external circulation filter element of the agricultural machinery described in the above embodiment.

[0043] This utility model places the filter element 5 in the mounting box 4 and then assembles it on the top cover body 1. The filter element 5 can be removed along with the mounting box 4. During removal, dust on the filter element 5 will not fall down, thus avoiding the impact on the interior environment of the cab and the safety of the operator. Removal can be achieved simply by rotating the locking mechanism 7, making installation and removal convenient.
