Description

Technical Field

[0001] This utility model relates to the field of oil pan technology, specifically to an oil pan for a pumping unit gearbox that is easy to clean. Background Technology

[0002] The oil pan is a disc-shaped or box-shaped container at the bottom of the transmission. It is usually made of stamped steel or cast aluminum and is bolted to the bottom of the transmission housing. The oil pan has the function of storing oil, which contains the lubricating oil necessary for the normal operation of the transmission.

[0003] However, the current oil pan structure is simple and lacks a sedimentation area. This means that tiny metal shavings and other impurities generated during long-term operation of the gearbox are fully extracted, putting a burden on the gearbox's filter screen. Furthermore, during subsequent oil draining, impurities cannot be discharged with the lubricating oil, especially impurities attracted by magnets, which affects the efficiency of subsequent cleaning. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an easy-to-clean oil pan for a pumping unit gearbox, by adding a guide plate and forming a groove, which provides an area for impurities to settle and enter the sludge collection channel, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: an easy-to-clean oil pan for a pumping unit gearbox, comprising an oil pan, a guide plate installed in the middle of the inner cavity of the oil pan by a first bolt, grooves formed between the guide plate and both ends of the oil pan, a groove provided on the bottom surface of the guide plate, a sludge collection channel formed between the groove and the oil pan, the sludge collection channel being connected to the groove, the two ends of the sludge collection channel being inclined and protruding to form a first guide part, the bottom surface of the groove being inclined and protruding to form a second guide part, the two sides of the groove protruding to form guide blocks, and a magnetic suction mechanism installed on the bottom surface of the oil pan.

[0006] As a preferred technical solution, the magnetic attraction mechanism includes a base plate, multiple second bolts and multiple magnets. The base plate is fitted to the bottom surface of the oil pan, and multiple positioning grooves are provided on the inner side of the base plate. The magnets are all placed in the positioning grooves and are all pressed and fixed by the base plate and the oil pan. The two sides of the base plate protrude to form connecting parts, and the second bolts pass through the connecting parts to fix the base plate to the oil pan.

[0007] As a preferred technical solution, the bottom plate and the sludge collection channel are arranged opposite each other, and a through hole is provided in the middle of the bottom plate. An oil drain pipe is provided on the bottom surface of the oil pan directly opposite the through hole.

[0008] As a preferred technical solution, the middle of the sewage collection channel is the lowest point, and it is gradually raised along the first guide section and the second guide section.

[0009] As a preferred technical solution, the open end of the oil pan is bent outward to form a flange, and a mounting groove matching the shape of the flange is recessed on the surface of the flange. A sealing ring is provided in the mounting groove, and multiple connecting fixing holes are provided on the sealing ring and the flange.

[0010] As a preferred technical solution, the first bolt is always located on the bottom surface of the oil pan.

[0011] As a preferred technical solution, the shank of the second bolt is covered by a guide plate.

[0012] The beneficial effects of this utility model are as follows: This utility model has a simple structure. By adding a guide plate, grooves are formed at both ends of the oil pan. The grooves provide a sedimentation area. Since the grooves and the sludge collection channel are equipped with a first guide part and a second guide part, and a magnet is also provided below the sludge collection channel, metal debris and impurities can be collected in the sludge collection channel, which greatly reduces the probability of being extracted again and reduces the burden on the filter screen. Moreover, the magnet can be disassembled externally. After the magnet loses its magnetic force, the internal dirt and metal debris can be fully discharged through the first guide part and the second guide part, increasing the fullness of sludge discharge and facilitating subsequent cleaning.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an easy-to-clean oil pan for a pumping unit gearbox, comprising an oil pan, a guide plate 1 installed in the middle of the inner cavity of the oil pan by a first bolt 6, grooves 2 formed between the guide plate 1 and both ends of the oil pan, a groove provided on the bottom surface of the guide plate 1, a sludge collection channel 11 formed between the groove and the oil pan, the sludge collection channel 11 being connected to the groove 2, the two ends of the sludge collection channel 11 being inclined and protruding to form a first guide portion, the bottom surface of the groove 2 being inclined and protruding to form a second guide portion 12, guide blocks 3 protruding on both sides of the groove 2, and a magnetic suction mechanism installed on the bottom surface of the oil pan.

[0020] In this embodiment, the magnetic attraction mechanism includes a base plate 7, multiple second bolts 13, and multiple magnets 10. The base plate 7 is fitted to the bottom surface of the oil pan, and multiple positioning grooves are provided on the inner side of the base plate 7. The magnets 10 are all set in the positioning grooves and are all pressed and fixed by the base plate 7 and the oil pan. The two sides of the base plate 7 protrude to form connecting parts 9, and the second bolts 13 pass through the connecting parts 9 to fix the base plate 7 to the oil pan. The magnets are permanent magnets to ensure service life.

[0021] In this embodiment, the bottom plate 7 is arranged opposite to the sludge collection channel 11, and a through hole 14 is provided in the middle of the bottom plate 7. An oil drain pipe 8 is provided on the bottom surface of the oil pan directly opposite the through hole 14.

[0022] In this embodiment, the middle of the sludge collection channel 11 is the lowest point, and it is gradually raised along the first guide section and the second guide section 12 so that the impurities at both ends can move towards the lower point.

[0023] In this embodiment, the open end of the oil pan is bent outward to form a flange 4. A mounting groove matching the shape of the flange 4 is recessed on the surface of the flange 4. A sealing ring 5 is provided in the mounting groove. Multiple fixing holes are provided on the sealing ring 5 and the flange 4.

[0024] In this embodiment, the first bolts 6 are all set on the bottom surface of the oil pan; the shank of the second bolts 13 is covered by the guide plate 1. The bottom surface of the oil pan is provided with a plurality of first screw holes and second screw holes, while the bottom surface of the guide plate is provided with a third screw hole. The third screw hole is arranged opposite to the first screw hole, and the first bolt is threaded into the first screw hole and the third screw hole.

[0025] The connecting part is provided with a fourth screw hole, which is opposite to the second screw hole, so that the second bolt is threaded into the fourth screw hole and the second screw hole. The first screw hole and the second screw hole are both sealed by the guide plate to avoid exposure. In order to increase the sealing performance, grooves can be made on the bottom surface of the guide plate, and a rubber layer is installed during installation.

[0026] Because the baffle is detachable, the bolts can be unscrewed during subsequent cleaning to remove the baffle and fully expose the sludge collection channel, thus ensuring the quality of cleaning.

[0027] Working principle: The added guide plate forms grooves at both ends of the oil pan, which provide a sedimentation area for impurities to settle. The grooves and the sludge collection channel are equipped with a first guide section and a second guide section, with the second guide section being higher than the first guide section. In addition, a magnet is installed below the sludge collection channel, which causes metal debris and impurities to gather in the sludge collection channel, greatly reducing the probability of them being extracted again and reducing the burden on the filter screen.

[0028] The magnet is fixed to the outside of the oil pan by the base plate. Therefore, when draining the oil, the second bolt can be unscrewed first, and the base plate and magnet can be removed. This avoids the magnet constantly attracting metal debris and preventing it from draining smoothly. After completion, the oil plug in the drain channel is opened. After the magnetic force of the magnet is lost, the oil can carry away the dirt and metal debris as it passes through the second guide section and the first guide section, increasing the thoroughness of the drainage and facilitating subsequent cleaning.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
