Description

Technical field:

[0001] The invention relates to the technical field of garlic harvesters, and in particular to a high-efficiency heat dissipation method for an engine of a garlic harvester. Background technology:

[0002] At present, the radiator is mainly used for heat dissipation of the engine on the garlic harvester. The commonly used radiator is a water tank radiator, whose structure mainly includes an upper water chamber, a radiator core (heat sink), a lower water chamber and a cooling fan. The cooling fan is driven by the engine to suck the outside air into the radiator. The upper water chamber and the lower water chamber are connected through the radiator core. The lower water chamber is connected to the water pump through the water outlet pipe. The water pump is connected to the heat dissipation circulation pipeline on the engine through the water pipe. The heat dissipation circulation is connected to the upper water chamber through the water inlet pipe. When the cooling fan is working, the outside air is accelerated to circulate through the heat dissipation core, thereby achieving the purpose of rapid cooling.

[0003] The above heat dissipation method can meet the heat dissipation requirements for scenes with good working environment, but the working environment of garlic harvester is relatively poor, which undoubtedly brings challenges to the existing heat dissipation method. When the garlic harvester is operating, a large amount of dust and debris (broken leaves, broken stalks, etc.) will be generated around it. Since the radiator adopts the method of inhaling air for heat dissipation, the air inhaled by the radiator when working will contain a large amount of dust and debris, and these dust and debris will adhere to it when passing through the heat dissipation core. After a short period of use, a layer of dust will adhere to the surface of the heat dissipation core, and even some weeds and debris will adhere to the heat dissipation core. This not only seriously affects the heat exchange between the heat dissipation core and the air, but also the air circulation will be blocked, which will eventually seriously affect the heat dissipation efficiency and effect of the radiator, and the problem of engine heating is prominent. Therefore, it is necessary to optimize and improve the existing radiator so that the radiator can operate well for a long time.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention:

[0005] The purpose of the present invention is to solve the problems existing in the prior art and provide an efficient heat dissipation method for an engine of a garlic harvester. The method optimizes and improves the existing water tank radiator and adopts source dust prevention, multiple dust prevention measures and precise temperature control to achieve the purpose of efficient heat dissipation of the engine.

[0006] The present invention achieves the above-mentioned purpose by adopting the following technical solutions:

[0007] An efficient heat dissipation method for an engine of a garlic harvester includes a water tank radiator, an air guide box is sealed and connected to the air inlet end of the water tank radiator, the air guide box is vertically arranged, an air inlet is designed on the outer wall of the upper end of the air guide box, an air outlet is designed on the inner wall of the lower end of the air guide box, the air outlet is directly connected to the water tank radiator, and the height of the air inlet relative to the air outlet is designed to be 1m to 1.5m; the direction in which air enters from the air inlet is designed to be perpendicular to the air guide box, and the direction in which air is discharged from the air outlet is designed to be perpendicular to the air guide box; a dustproof net is designed at the air inlet, and an air intake grille is designed on the housing of the garlic harvester corresponding to the position of the air inlet;

[0008] A cooling plate is designed on the outer wall of the upper water chamber of the water tank radiator, and the heat absorbing surface of the cooling plate is attached to the outer wall of the upper water chamber. The cooling plate is connected to the power supply through a control switch. A temperature sensor is designed on the lower water chamber of the water tank radiator. The temperature sensor transmits water temperature data to the controller in real time. When the water temperature exceeds the set value, the controller starts the cooling plate through the control switch to efficiently cool the water in the upper water chamber.

[0009] The air guide box is designed to be a cuboid in shape, and the upper ends of the two side walls of the air guide box are respectively provided with side air inlets, and the side air inlets are provided with side dustproof nets.

[0010] A cooling fin is provided on one side of the upper water chamber close to the air guide box body, and cooling ribs are provided on the heat dissipation surface of the cooling fin. An opening is provided at the air outlet end of the air guide box body, and an air guide cover plate is rotatably provided at the opening. An electric cylinder is rotatably provided on the air guide box body, and the electric cylinder is rotatably connected to the air guide cover plate. The electric cylinder is connected to a power supply via a control switch B, and the control switch B is connected to a controller. The air guide cover plate guides air in the direction of the cooling fin.

[0011] The lower end of the air guide box is arranged on the engine mounting frame.

[0012] An inspection door is provided on the outer side wall of the lower end of the air guide box body.

[0013] The present invention adopts the above structure, which can bring the following beneficial effects:

[0014] (1) On the basis of adopting the existing water tank radiator, the incoming air is optimized and improved, and the following design is achieved by designing the air guide box. First, the height of the air inlet is raised. When the garlic harvester is working, dust, debris, etc. are mainly concentrated at a height below 1 meter. The higher the air is, the cleaner it is. Therefore, by raising the air inlet, the dust intake can be reduced from the root; the dust entry is further reduced by designing a dustproof net; by designing the air to collide with the air intake box when entering, and collide with the air guide box again when the air is discharged, the dust entering the air intake box will be trapped in the air intake box due to the two collisions, and ultimately greatly reduce the possibility of dust entering the water tank radiator, thereby ensuring the long-term good operation of the water tank radiator; (2) Considering that garlic harvesting is relatively concentrated, the engine needs to work continuously for a long time, and sometimes relying solely on the water tank radiator for heat dissipation will result in untimely heat dissipation. Adding active and efficient heat dissipation means, especially using refrigeration plate technology, can achieve rapid and efficient cooling of the circulating water, thereby achieving the purpose of efficient heat dissipation of the engine.

Specific implementation method:

[0023] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0026] Furthermore, terms such as "upper end" and "lower end" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the position of the indicated technical features.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1-7As shown, the garlic harvester engine efficient heat dissipation method includes a water tank radiator 1, the water tank radiator belongs to the prior art, includes an upper water chamber 101, a radiator core 102, a lower water chamber 103 and a cooling fan 104, wherein the cooling fan 104 is connected to the output shaft of the engine 22, the lower water chamber 103 is connected to a water outlet pipe 23, the water outlet pipe 23 is connected to a water pump 24, the water pump 24 is driven by the engine 22, the water pump 24 is connected to a circulating water cooling channel (prior art) on the engine 22 through a water pipe, and the circulating water cooling channel is connected to a water inlet pipe 25 (return pipe) on the upper water chamber 101; in the water tank radiator 1 The air inlet end is sealed and connected to an air guide box 2, the air guide box 2 is vertically arranged, an air inlet 3 is designed on the outer wall of the upper end of the air guide box 2, and an air outlet 4 is designed on the inner wall of the lower end of the air guide box 2, the air outlet 4 is directly connected to the water tank radiator 1, and the height of the air inlet 3 relative to the air outlet 4 is designed to be 1m to 1.5m; the direction in which air enters from the air inlet 3 is designed to be perpendicular to the air guide box 2, and the direction in which air is discharged from the air outlet 4 is designed to be perpendicular to the air guide box 2; a dustproof net 5 is designed at the air inlet 3, and an air intake grille 7 is designed on the housing 6 of the garlic harvester corresponding to the position of the air inlet 3;

[0029] A cooling sheet 8 (i.e., a semiconductor cooling sheet, also called a thermoelectric cooling sheet, whose working principle belongs to the prior art) is designed on the outer wall of the upper water chamber 101 of the water tank radiator 1, and the heat absorption surface of the cooling sheet 8 is attached to the outer wall of the upper water chamber 101. The cooling sheet 8 is connected to a power supply 10 (the power supply here is preferably a power supply on a garlic harvester) through a control switch 9. A temperature sensor 11 is designed on the lower water chamber 103 of the water tank radiator 1. The temperature sensor 11 transmits the water temperature data to a controller 12 in real time (the controller on a garlic harvester can be used, and if there is no controller, a third-party controller can be directly purchased). When the water temperature exceeds the set value, the controller 12 starts the cooling sheet 8 through the control switch 9 to efficiently cool the water in the upper water chamber 101. That is, when the heat dissipation effect of the water tank radiator 1 does not meet expectations, the cooling sheet is started to dissipate heat, and the two cooperate to achieve efficient heat dissipation of the engine. On the basis of adopting the existing water tank radiator 1, the incoming air is optimized and improved, and the following design is realized by designing the air guide box 2. First, the air inlet 3 is raised. When the garlic harvester is working, dust, debris, etc. are mainly concentrated at a height below 1 meter. Since the water tank radiator needs to be connected to the engine, the installation height of the water tank radiator is basically consistent with the engine, and the installation height of the engine is about 0.5m, which is exactly where dust and debris are concentrated. Therefore, by raising the air inlet 3, the dust inhalation can be reduced from the root; the dust entry is further reduced by designing the dustproof net 5; and the air inlet is designed to be When the garlic is harvested in a concentrated manner, the engine needs to work continuously for a long time. Sometimes, if the heat is only dissipated by the water tank radiator 1, the heat dissipation may not be timely. Therefore, adding active and efficient heat dissipation means, especially using the refrigeration sheet 8 technology, can realize rapid and efficient cooling of the circulating water, thereby achieving the purpose of efficient heat dissipation of the engine 19.

[0030] The air guide box 2 is designed to be a cuboid, and the upper ends of the two side walls of the air guide box 2 are respectively provided with side air inlets 13, and the side air inlets 13 are provided with side dust screens 14. Considering that adding the dust screen 5 to the air inlet 3 will reduce the amount of air entering, in order to compensate for the amount of air entering, side air inlets and side dust screens 14 are provided on both sides, so as to ensure the amount of air entering while ensuring the dustproof effect, thereby helping to ensure the heat dissipation effect.

[0031] A cooling fin 8 is provided on the side of the upper water chamber 101 close to the air guide box 2, and a heat dissipation rib 15 is provided on the heat dissipation surface of the cooling fin 8. An opening 16 is provided at the air outlet 4 end of the air guide box 2, and an air guide cover plate 17 is rotatably provided at the opening 16. An electric cylinder 18 is rotatably provided on the air guide box 2, and the electric cylinder 18 is rotatably connected to the air guide cover plate 17. The electric cylinder 18 is connected to the power supply 10 through a control switch B19, and the control switch B19 is connected to the controller 12. The air guide cover plate 17 guides air to the direction of the cooling fin 8. Although the cooling fin 8 can cool down quickly, its heat dissipation surface also needs to quickly dissipate heat to ensure its continuous and reliable cooling effect. The heat dissipation area is increased by designing the heat dissipation rib 15, and at the same time, a small part of the inhaled air is led out to quickly dissipate the heat of the heat dissipation rib 15, so as to achieve comprehensive utilization of the inhaled air and ensure the heat dissipation effect.

[0032] The lower end of the air guide box 2 is arranged on the engine mounting frame 20. Since the bottom of the water tank radiator 1 is also arranged on the engine mounting frame 20 for support, installing the bottom of the air guide box 2 on the engine mounting frame 20 is not only convenient for installation, but also convenient for the air outlet 4 to be aligned with the water tank radiator 1 and sealed and connected.

[0033] An inspection door 21 is provided on the outer side wall of the lower end of the air guide box 2. Since the air guide box 2 is provided at the air inlet end of the water tank radiator 1, it is very inconvenient to inspect the water tank radiator 1. By designing the inspection door 21, the water tank radiator 1 can be inspected without disassembling the air guide box 2.

[0034] The above specific implementation manner cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art, any substitution, improvement or change made to the implementation manner of the present invention falls within the protection scope of the present invention.

[0035] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
