Abstract
Description
Technical Field
[0001] The invention relates to the technical field of agricultural tractors, and in particular to an agricultural tractor with a power cooling device. Background Art
[0002] The structure of the current agricultural hand-held tractor is mainly that a diesel engine and a control device are arranged above the longitudinal beam, wheels are arranged below the longitudinal beam, and a cooling water tank is arranged above the diesel engine. Due to its simple and practical structure, it is widely used in rural areas.
[0003] The conventional power of existing small agricultural walking tractors is an evaporative engine, and the cooling water in the water tank relies on air convection and outward conduction of the water tank to dissipate heat. This natural way of dissipating heat is slow.

When cultivating farmland for a long time, the consumption of cooling water is large and cooling water needs to be added frequently. However, there may be a lack of relatively clean water resources around the farmland, which makes the addition of cooling water time-consuming and labor-intensive, reducing the use efficiency.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. See also Figure 1-12 The present embodiment provides an agricultural tractor with a power cooling device, comprising a longitudinal beam 1, a diesel engine 11 and a control device are arranged above the longitudinal beam 1, and a wheel 12 is arranged below the longitudinal beam 1, a heat dissipation water tank 13 is arranged above the diesel engine 11, a circulating heat dissipation pipe 14 is welded on the outer side of the longitudinal beam 1, and the two ends of the circulating heat dissipation pipe 14 are respectively fixedly connected with a vibrating water injection mechanism and a circulating water pipe 15, and a filter plate 111 is embedded and installed at one end of the circulating heat dissipation pipe 14 close to the circulating water pipe 15 through bolts, and a collecting barrel 112 is threadedly connected at the bottom of the circulating heat dissipation pipe 14 and located on the side of the filter plate 111 away from the circulating water pipe 15, and the collecting barrel 112 is connected to the circulating heat dissipation pipe 14. The filter plate 111 is arranged to filter and intercept the cooling water refluxed into the heat dissipation water tank 13 to improve the cleanliness of the cooling water. The impurities intercepted by 1 fall into the collection bucket 112 under the action of gravity. The setting of the collection bucket 112 is used to uniformly collect the impurities intercepted by the filter plate 111. The end of the circulating water pipe 15 away from the circulating heat dissipation pipeline 14 is fixedly connected with the position near the top of the heat dissipation water tank 13, so that when the cooling water returns to the heat dissipation water tank 13, there is a height difference with the cooling water level in the heat dissipation water tank 13, thereby realizing the phenomenon of pouring water from a high place, increasing the contact time between the cooling water returning to the heat dissipation water tank 13 and the air, and improving the cooling effect. The vibrating water injection mechanism is used to inject the cooling water in the heat dissipation water tank 13 into the circulating heat dissipation pipeline 14 and use the longitudinal beam 1 to dissipate heat. A mounting port 16 is provided on one side of the circulating heat dissipation pipeline 14, and a blocking mechanism 1 for blocking the mounting port 16 is provided at the position of the inner wall of the circulating heat dissipation pipeline 14 corresponding to the mounting port 16; A mounting frame 17 is welded to one side of the longitudinal beam 1, a mounting frame 18 is movably inserted inside the mounting frame 17, a tillage agricultural tool 19 is fixedly mounted on the mounting frame 18, a circulating heat dissipation channel is opened inside the tillage agricultural tool 19, a circulating connection mechanism is fixedly mounted on one end of the tillage agricultural tool 19 close to the circulating heat dissipation pipeline 14, the circulating connection mechanism is used to connect the circulating heat dissipation pipeline 14 with the circulating heat dissipation channel, so that the cooling water in the circulating heat dissipation pipeline 14 flows back to the circulating heat dissipation pipeline 14 through the circulating heat dissipation channel; In actual application, when the tillage implements 19 on the agricultural tractor are removed and replaced with a carriage for transporting goods (such as fertilizers, seeds, etc.), the agricultural tractor is restricted from being put on the road (the "road" referred to in the Road Traffic Safety Law) due to insufficient safety performance, driver problems and many management issues. Therefore, the application scope of agricultural tractors is usually farmland cultivation and short-distance cargo transportation on rural roads. Since the agricultural tractor is not in a long-term continuous operation in a tillage state, the heat dissipation demand of the diesel engine 11 is reduced. The vibrating water injection mechanism utilizes the strong vibration characteristics of the agricultural tractor to continuously inject the cooling water in the cooling water tank 13 into the circulating cooling pipe 14, and then returns the cooling water to the cooling water tank 13 through the circulating water pipe 15, so that the cooling water is always circulating on the outside of the longitudinal beam 1, thereby transferring the heat of the cooling water to the longitudinal beam 1, thereby The large volume of the longitudinal beam 1 is utilized to increase the contact area with the air, improve the heat dissipation effect of air convection, thereby strengthening the cooling and heat dissipation effect of the cooling water, effectively improving the cooling effect of the cooling water tank 13 on the diesel engine 11, and improving the working performance of the diesel engine 11; and when the agricultural tractor is equipped with a tillage agricultural tool 19 for tilling the farmland, the water in the cooling water tank 13 is injected into the circulating heat dissipation pipe 14 and the tillage agricultural tool 19 for tillage, thereby transferring the heat of the cooling water to the longitudinal beam 1 and the tillage agricultural tool 19. While the longitudinal beam 1 is used for heat dissipation, the tillage agricultural tool 19 is simultaneously used to transfer the heat of the cooling water to the ground. The tillage agricultural tool 19 is in a state of continuous movement during use, which can avoid the local soil temperature being too high and affecting the heat dissipation of the cooling water, and effectively ensure the efficient heat dissipation effect of the tillage agricultural tool 19 on the cooling water.
[0023] In an embodiment further provided by the present invention, the vibration water injection mechanism includes a water injection pipe 21 fixedly connected and installed on the circulating heat dissipation pipeline 14, the other end of the water injection pipe 21 is fixedly connected to a piston cylinder 22, the other end of the piston cylinder 22 is fixedly connected to a limiting cylinder 23, the interior of the piston cylinder 22 is movably connected to a water injection piston 24, the water injection piston 24 and the piston cylinder 22 are arranged with an interference fit, the top of the water injection piston 24 is fixedly connected to a vertical rod 25, the bottom end of the vertical rod 25 movably passes through the piston cylinder 22 and extends to the interior of the limiting cylinder 23, one end of the vertical rod 25 extending to the interior of the limiting cylinder 23 is fixedly connected to a trigger plate 26, the top of the trigger plate 26 and the inner wall of the limiting cylinder 23 are fixedly connected with a buffer rubber 27, a vibration trigger steel ball 28 is placed above the trigger plate 26, and the vibration trigger steel ball 28 is located above the rubber block at the top of the trigger plate 26, A compression spring 29 is fixedly connected between the bottom of the trigger plate 26 and the top of the piston cylinder 22 and on the outer surface of the vertical rod 25. The compression spring 29 is initially in a compressed state. A one-way valve 210 is provided at one end of the water injection pipe 21 close to the piston cylinder 22. The flow direction of the one-way valve 210 is from the piston cylinder 22 to the water injection pipe 21, and reverse flow is not possible. The piston cylinder 22 and the heat dissipation water tank 13 are fixedly connected via a connecting pipe 211. A one-way valve 212 is provided inside the connecting pipe 211. The flow direction of the one-way valve 212 is from the heat dissipation water tank 13 to the piston cylinder 22, and reverse flow is not possible. By utilizing the strong vibration characteristics of the agricultural tractor through the vibrating water injection mechanism, the cooling water in the heat dissipation water tank 13 can be continuously injected into the circulating heat dissipation pipe 14 without an additional power source, so that the heat of the cooling water is conducted to the longitudinal beam 1 by utilizing the circulating heat dissipation pipe 14 for heat dissipation.
[0024] Furthermore, a sealing ring 3 is embedded on the inner wall of the installation opening 16. The provision of the sealing ring 3 can improve the sealing performance of the connection between the circulation connection mechanism and the installation opening 16, thereby preventing the cooling water in the circulation heat dissipation pipeline 14 from leaking from the gap.
[0025] Furthermore, the blocking mechanism 1 includes a accommodating cylinder 41 fixedly connected to the circulating heat dissipation pipeline 14, the position of the accommodating cylinder 41 is set corresponding to the position of the mounting port 16, a return spring 42 is fixedly connected to the inner wall of the accommodating cylinder 41, the other end of the return spring 42 is fixedly connected to a blocking plate 43 for blocking the mounting port 16, and the front and back sides of the blocking plate 43 are fixedly connected to the limiting protrusion 44. Through the setting of the blocking mechanism 1, when the farmland agricultural tool 19 is removed from the circulating heat dissipation pipeline 14, the elastic force of the return spring is used to The sealing plate 43 is pushed toward the position of the installation port 16 until the sealing plate 43 blocks the installation port 16 to prevent cooling water from flowing out from the position of the installation port 16, thereby ensuring that the circulating heat dissipation pipe 14 can normally circulate and dissipate cooling water. Moreover, through the setting of the limiting protrusion 44, after the sealing plate 43 blocks the installation port 16, the sealing plate 43 is limited to prevent the sealing plate 43 from passing through the installation port 16 and moving out of the circulating heat dissipation pipe 14, thereby ensuring that the sealing plate 43 can just stop inside the installation port 16 to achieve the blocking of the installation port 16.
[0026] In an embodiment further provided by the present invention, a limiting mechanism for limiting the blocking plate 43 is further provided on the longitudinal beam 1, and the limiting mechanism includes a moving rod 51 and a limiting rod 52, the moving rod 51 is fixedly installed on one side of the blocking plate 43 close to the limiting spring 1, the other end of the moving rod 51 movably penetrates the accommodating tube 41 and extends to the inside of the accommodating tube 41, a limiting hole 53 is provided on the top of the moving rod 51, the limiting rod 52 is movably penetrated and installed on the longitudinal beam 1, and the outer surface of the limiting rod 52 is fixedly connected There is a support plate 54, and a compression spring 55 is fixedly connected between the support plate 54 and the longitudinal beam 1 and on the outside of the limiting rod 52. A guide slope 56 is provided at the bottom end of the limiting rod 52, and a sealing ring 57 is provided at the connection between the moving rod 51 and the accommodating cylinder 41. Through the setting of the limiting mechanism, when the sealing plate 43 blocks the installation opening 16, the sealing plate 43 can be locked and fixed to prevent the sealing plate 43 from loosening due to the vibration of the tractor, thereby ensuring the sealing effect of the sealing plate 43 on the installation opening 16.
[0027] In the embodiment provided by the present invention, a water inlet 61 is provided at the top of the heat dissipation water tank 13, and a filter frame 62 is provided inside the water inlet 61. The setting of the water inlet 61 not only facilitates the user to add cooling water to the heat dissipation water tank 13, but also enables the heat dissipation water tank 13 to circulate with the external air so as to dissipate heat and cool the cooling water in the heat dissipation water tank 13. The setting of the filter frame 62 can intercept external impurities and prevent impurities from entering the heat dissipation water tank 13.
[0028] Specifically, the circulation connection mechanism includes a connection frame 71 movably inserted in the installation port 16, and the front and back sides of the connection frame 71 are respectively provided with a water inlet channel 72 and a water return channel 73, and the water inlet channel 72 and the water return channel 73 are respectively connected to the two ends of the circulation heat dissipation channel inside the farm tool 19, and the front and back sides of the connection frame 71 are both provided with a mounting groove 74, and the interior of the mounting groove 74 is provided with a second blocking mechanism for blocking the water inlet channel 72 and the water return channel 73, and the second blocking mechanism includes a second blocking mechanism movably installed in the mounting groove. A sealing plate 81 is provided on the inner wall of the mounting groove 74, and a return spring 82 is fixedly connected to the side of the sealing plate 81 away from the circulating heat dissipation pipe 14, and the other end of the return spring 82 is fixedly connected to the inner wall of the mounting groove 74, and a contact plate 83 is fixedly connected to the side of the sealing plate 81 away from the connecting frame 71; through the setting of the circulating connecting mechanism, the cooling water in the circulating heat dissipation pipe 14 can be transported to the farm tool 19 for cultivated land, so that the heat of the cooling water is transferred to the ground through the farm tool 19 for cultivated land, thereby improving the cooling effect of the cooling water.
[0029] In a solution further provided by the present invention, a plurality of heat dissipation fins 9 are fixedly connected to the inner wall of the longitudinal beam 1. The arrangement of the heat dissipation fins 9 can greatly increase the contact area between the longitudinal beam 1 and the air, thereby improving the heat dissipation effect of the longitudinal beam 1 on cooling water.
[0030] In the solution further provided by the present invention, a plurality of through grooves 101 are provided between the top and bottom of the mounting frame 17 and the mounting frame 18, and a limit pin 102 is movably inserted in at least one of the through grooves 101. By using the through grooves 101 and the limit pin 102 in coordination, the mounting frame 18 can be fixedly installed in the mounting frame 17, thereby achieving the installation of the tillage agricultural tool 19 on the mounting frame 17, and completing the installation of the tillage agricultural tool 19 on the tractor. When installing the carriage, the principle is the same as that of installing the tillage agricultural tool 19. The mounting frame 18 on the carriage (the size of the mounting frame 18 is smaller than the size of the mounting frame 17) is movably installed in the mounting frame 17 using a single limit pin 102, and the carriage and the mounting frame 17 can rotate relative to each other.
[0031] Working principle: When the agricultural tractor needs to be used for farmland cultivation, the embodiment of the present application takes a plough as an example. In actual application, a plough harrow can also be replaced (the interior of the plough harrow is also provided with a circulating heat dissipation channel). The user first injects a proper amount of cooling water (clean water) into the heat dissipation water tank 13 through the water injection port 61. During the process of injecting cooling water, impurities in the cooling water are filtered and intercepted by the filter frame 62. The diesel engine 11 generates a lot of heat when running, and the cooling water in the heat dissipation water tank 13 is used to cool the diesel engine 11. At the same time, the agricultural tractor will generate strong vibrations when running, thereby driving the vibration to trigger the steel ball 2 8 jumps up and down in the limit cylinder 23. In the initial state, the compression spring 29 is in a compressed state. When the vibration triggering steel ball 28 jumps upward due to the vibration of the tractor, the pressure on the trigger plate 26 disappears. At this time, the trigger plate 26 is pushed upward by the elastic force of the compression spring 29, and the water injection piston 24 is driven to move upward synchronously through the vertical rod 25. The chamber inside the piston cylinder 22 located below the water injection piston 24 is in a negative pressure state, and then the cooling water in the heat dissipation water tank 13 is attracted to the inside of the piston cylinder 22 through the connecting pipe 211. Then, when the vibration triggering steel ball 28 falls, the gravity of the vibration triggering steel ball 28 and the impact of the fall are used to release the cooling water in the cooling water tank 13. The impact force drives the trigger plate 26 to move downward, thereby driving the water injection piston 24 to move downward, and injecting the cooling water inside the piston cylinder 22 into the circulating heat dissipation pipe 14 through the water injection pipe 21. Therefore, in the process of the vibration triggering steel ball 28 to bounce back and forth up and down, the cooling water in the heat dissipation water tank 13 will be continuously extracted and injected into the circulating heat dissipation pipe 14. The cooling water entering the circulating heat dissipation pipe 14 flows from the water inlet channel 72 on the connecting frame 71 to the circulating heat dissipation channel inside the cultivated land agricultural tool 19, and then flows into the circulating heat dissipation pipe 14 again through the return water channel 73 on the connecting frame 71, and flows back to the circulating water pipe 15 through the circulating water pipe 15. In the heat dissipation water tank 13, when the cooling water flows in the circulating heat dissipation pipe 14, the heat can be transferred to the longitudinal beam 1, thereby utilizing the large volume characteristics of the longitudinal beam 1 to increase the contact area with the air and improve the air convection heat dissipation effect. When the cooling water passes through the cultivated land agricultural tool 19, the heat is transferred to the cultivated land agricultural tool 19. The cultivated land agricultural tool 19 is inserted in the soil to transfer the heat of the cooling water to the ground. The cultivated land agricultural tool 19 is in a state of continuous movement during use, which can avoid the local soil temperature being too high to affect the heat dissipation of the cooling water, and effectively ensure the efficient heat dissipation effect of the cultivated land agricultural tool 19 on the cooling water; When the agricultural tractor is no longer needed for farmland cultivation, the limit pin 102 is manually lifted up to completely withdraw it from the through slot 101 to release the limit fixation on the mounting frame 18, and then the tillage agricultural tool 19 is moved to the side away from the mounting frame 17, so that the mounting frame 18 moves toward the outside of the mounting frame 17. At the same time, the connecting frame 71 is driven to move toward the outside of the circulating heat dissipation duct 14, and the sealing plate 43 is pushed to move synchronously with the movement of the connecting frame 71 through the elastic force of the reset spring 42. When the connecting frame 71 completes withdrawal from the mounting opening 16, the disassembly of the tillage agricultural tool 19 can be completed. At this time, the sealing plate 43 just blocks the mounting opening 16, and the position of the limit rod 52 is just opposite to the position of the limit hole 53. The limit rod 52 is pushed to embed into the limit hole 53 on the moving rod 51 through the elastic force of the compression spring 55. The movable rod 51 is limited and fixed in the hole 53, so as to improve the stability of the sealing plate 43 blocking the installation opening 16, avoid the sealing plate 43 from loosening due to vibration during the subsequent operation of the agricultural tractor, ensure the sealing effect of the sealing plate 43 on the installation opening 16, and the sealing ring 3 is provided to improve the sealing performance of the connection between the sealing plate 43 and the installation opening 16, so as to prevent the cooling water inside the circulating heat dissipation pipeline 14 from leaking from the position of the installation opening 16, and when the connecting frame 71 moves toward the outside of the installation opening 16, the elastic force of the reset spring 2 82 pushes the sealing plate 2 81 to move, and the water inlet channel 72 and the water return channel 73 are blocked, so as to prevent impurities from entering the water inlet channel 72 and the water return channel 73 after the connecting frame 71 withdraws from the installation opening 16, thereby avoiding the blockage of the pipeline due to the impurities in the connecting frame 71 when it is used next time; After the farm implement 19 is disassembled, that is, when there is no need for farming, the use scenario of the farm tractor is to install the carriage in the installation frame 17 through the limit pin 102 to carry out short-distance transportation of goods (such as fertilizers, seeds, etc.). Since the farm tractor is not in a long-term continuous operation in a farming state, the heat dissipation demand of the diesel engine 11 is reduced at this time. The cooling water in the heat dissipation water tank 13 is continuously injected into the circulating heat dissipation pipe 14 through the vibrating water injection mechanism using the strong vibration characteristics of the farm tractor, and then the cooling water is returned to the heat dissipation water tank 13 through the circulating water pipe 15, so that the cooling water is always circulating on the outside of the longitudinal beam 1, thereby conducting the heat of the cooling water to the longitudinal beam 1, and performing large-area efficient heat dissipation. In addition, the contact area between the longitudinal beam 1 and the air is further increased by the arrangement of the heat dissipation fins 9, thereby further strengthening the cooling and heat dissipation effect of the cooling water, thereby effectively improving the cooling effect of the heat dissipation water tank 13 on the diesel engine 11, and improving the working performance of the diesel engine 11; Each time the tillage agricultural tool 19 is installed on the agricultural tractor, the soil impurities on the outside of the connecting frame 71 on the tillage agricultural tool 19 are first cleaned, and the side of the sealing plate 43 located outside the circulation heat dissipation pipe 14 is cleaned to prevent the subsequent connecting frame 71 from being inserted into the circulation heat dissipation pipe 14. When the connecting frame 71 and the sealing plate 43 are cleaned, the user lifts the limit rod 52 to make it withdraw from the limit hole 53, releases the limit fixation of the moving rod 51, and then inserts the mounting frame 18 into the mounting frame 17. At the same time, the connecting frame 71 pushes the sealing plate 43 to move toward the inside of the circulation heat dissipation pipe 14. The abutment plate 83 abuts against the circulating heat dissipation pipe 14, and when the connecting frame 71 moves, the abutment plate 83 and the connecting frame 71 are in a relative position, and the sealing plate 81 and the water inlet channel 72 and the return channel 73 are relatively displaced, so that after the connecting frame 71 is inserted into the installation port 16, the circulating heat dissipation pipe 14 and the water inlet channel 72 and the return channel 73 are in a connected state, thereby ensuring that the cooling water in the circulating heat dissipation pipe 14 can smoothly enter the circulating heat dissipation channel inside the cultivated land agricultural tool 19 from the water inlet channel 72, and then flow back to the circulating heat dissipation pipe 14 through the return channel 73, so that the cooling water circulates from the inside of the cultivated land agricultural tool 19 to transfer heat to the soil.
