Description

TECHNICAL FIELD

[0001] The application relates to the technical field of refrigeration equipment, and particularly relates to a vehicle-mounted mobile agricultural product high-efficiency refrigeration device. BACKGROUND

[0002] After the agricultural products are picked, rapid cooling treatment is carried out in the field or nearby, which aims to rapidly remove the "field heat" carried by the agricultural products from the field and the continuous respiratory heat of the agricultural products, so that the core temperature of the agricultural products is reduced to a suitable low temperature in the shortest time. The effect of this technology is crucial, because the agricultural products are still living organisms after being picked, and will continuously carry out respiration and release heat. If not pre-cooled in time, the high temperature will accelerate the water loss, nutrient consumption, texture softening and aging process of the agricultural products, and create conditions for the reproduction of microorganisms, resulting in accelerated corruption and deterioration. Through rapid pre-cooling, the respiration intensity and enzyme activity of the agricultural products can be effectively inhibited, the metabolic speed is slowed down, and the original freshness, color, flavor, nutrition and firmness of the agricultural products are maximally maintained, and the postharvest preservation period and shelf life of the agricultural products are significantly prolonged. At the same time, pre-cooling can also reduce the refrigeration load of the subsequent cold chain links, lay a foundation for efficient and energy-saving long-distance transportation and storage, and is a key link for ensuring the stability of the quality of agricultural products from the field to the table and reducing the loss.

[0003] A differential pressure pre-cooling box is disclosed in Chinese patent document CN216080510U, which comprises a box body, a pre-cooling chamber and a mechanical chamber are formed adjacent to each other in the front and back of the box body, a temperature insulation plate is arranged between the pre-cooling chamber and the mechanical chamber, an air inlet and an air outlet are formed in the temperature insulation plate, and the air outlet is arranged above the air inlet. The overall structure design of the box body is similar to that of a container or a cold chain transport box, which is convenient for loading and transportation. The pre-cooling chamber is used for stacking agricultural products to be pre-cooled; the differential pressure pre-cooling box further comprises a cold storage bin, a centrifugal fan, a heat exchanger and a liquid pump arranged in the mechanical chamber. The cold storage bin is used for containing a predetermined cold storage agent, and the cold storage bin is arranged in a left-right spaced manner; the centrifugal fan is arranged between the two cold storage bins and corresponds to the air inlet in the front-rear direction; the heat exchanger is arranged between the centrifugal fan and the air outlet and above the cold storage bin and the centrifugal fan; and the liquid pump is used for conveying the cold storage agent to the heat exchanger. The differential pressure pre-cooling box further comprises a fan corresponding to the air outlet, which can usually adopt a predetermined specification of axial flow fan. Of course, a corresponding power module (not shown) is also arranged in the mechanical chamber, and the power module is used to drive the centrifugal fan, the liquid pump and the fan to work. An air suction duct is formed between the two cold storage bins, and in the actual working process, the centrifugal fan draws the air in the pre-cooling chamber into the air suction duct, and under the joint action of the fan, the air flows through the heat exchanger and is then discharged from the air outlet, so that the pre-cooling chamber is cooled.

[0004] In the aforementioned technology, during the operation of the air-cooled condenser in the refrigeration system, if it is during the rainy season, rainy days, or in coastal areas, the dew point temperature of the air is high (i.e., the air already contains a large amount of water vapor). When the dew point temperature of the air flowing through the heat dissipation fins in the refrigeration system is higher than the surface temperature of the heat dissipation fins, the water vapor in the air undergoes a phase change and condenses into liquid water on the fin surface. This process is more pronounced when the ambient humidity is high and the refrigeration system operates efficiently, keeping the fin temperature at a low level. The long-term retention of condensate will cause multiple adverse consequences: First, the continuous contact between liquid water and the surface of the metal fins will accelerate the electrochemical corrosion and oxidation of the fins, directly damaging the core heat exchange element. Firstly, the structural integrity and service life of the components are affected. Secondly, the water film on the fin surface significantly alters the boundary layer state of airflow and increases airflow resistance, leading to a decrease in heat exchange efficiency. This forces the compressor to operate at a higher load to compensate for the efficiency loss, resulting in a decrease in the overall system energy efficiency ratio and an increase in energy consumption. Furthermore, static water provides an ideal environment for the growth of microorganisms (such as algae and mold), and their metabolic products and biofilms further exacerbate dirt adhesion and corrosion. At the same time, in the actual operating environment, the heat dissipation fins inevitably come into contact with suspended particles such as dust, willow catkins, and leaves. These impurities, along with condensate, adhere to the fin surface, all of which lead to a decrease in heat dissipation efficiency. Summary of the Invention

[0005] This invention provides a vehicle-mounted mobile high-efficiency refrigeration device for agricultural products, aiming to solve the problem in related technologies where condensation or debris on the surface of heat dissipation fins leads to a decrease in the heat dissipation efficiency of the fins.

[0006] A vehicle-mounted mobile high-efficiency refrigeration device for agricultural products includes two manifolds and multiple horizontal flat tubes arranged vertically between the two manifolds. A gap exists between two adjacent horizontal flat tubes, and a corrugated heat sink is installed within the gap. A fan is located on the left side of the heat sink. The device also includes:

[0007] The dewatering mechanism includes an air collecting groove that is slidably installed on the front end face of the horizontal flat tube in the left-right direction and multiple air outlet pipes that are rotatably installed on the bottom of the air collecting groove. The air outlet pipes correspond one-to-one with the gaps. The air outlet pipes are used to guide the air in the air collecting groove to the heat sink. The air collecting groove is provided with a first driving component for driving the air outlet pipes to rotate. The rear end of the air outlet pipe is located in the gap. The collecting tube is provided with a second driving component for driving the air collecting groove to move.

[0008] When the air collection slot drives the air outlet pipe to pass over the vertical surface of the heat sink, the air outlet pipe comes into contact with the heat sink and deflects. After the air outlet pipe passes over the vertical surface of the heat sink, the air outlet pipe quickly deflects in the opposite direction and strikes the heat sink in the direction of its deflection.

[0009] The water removing mechanism composed of the air collecting groove and the air collecting groove is driven by the driving member II to move along the surface of the heat exchanger in a reciprocating linear motion, so that the whole surface of the heat exchanger is fully covered and automatically cleaned. During the movement, the air flow entering the air collecting groove forms a high pressure air flow when entering the air outlet pipe, and the high pressure air flow is accurately guided to the surface of the heat sink through the air outlet pipe, and the flow direction of the air flow is at an acute angle with the surface of the heat sink, so that the air flow directly blows to the surface of the heat sink and blows off the condensed water. Since the air outlet pipe is a deflection-rebound-knock composite cleaning action, when the air outlet pipe encounters the heat sink during movement, it will be passively deflected, rebound quickly after passing over the heat sink under the action of the driving member I, and knock on the heat sink behind by using the rebound inertia force. The cleaning method combining blowing and knocking can effectively remove the condensed water by using the impact force of the air flow and the stripping force of the mechanical vibration, and the cleaning effect is better than that of single air flow blowing. The whole process is automatic and does not need to stop, so that the heat exchanger can always be in operation.

[0010] Preferably, a collecting groove is arranged on the rear end surface of the parallel flat tube, and the collecting groove is used for collecting the condensed water or dust blown down by the air outlet pipe. A drain hole is arranged at the lower end of the collecting groove, and the air collecting groove is fixedly connected with the collecting groove.

[0011] By arranging the collecting groove, the condensed water blown down by the air outlet pipe on the heat sink is prevented from gathering around the whole device, so that the fan is prevented from sucking the condensed water blown down again and blowing it to the heat sink.

[0012] Preferably, the driving member I includes an elastic member I arranged between the air collecting groove and the air outlet pipe, and the elastic member I is used for making the air outlet pipe perpendicular to the vertical surface.

[0013] The elastic member I is used for providing a power source for the "deflection-rebound-knock" action of the air outlet pipe. When the air outlet pipe is deflected by the heat sink, the elastic member I is deformed and stores elastic energy. When the air outlet pipe passes over the heat sink, the stored elastic energy is rapidly released to drive the air outlet pipe to produce a high-speed reverse deflection and knocking action. This passive triggering structure does not need an additional control system and power source.

[0014] Preferably, the elastic member I is a torsion spring, and the two ends of the torsion spring are respectively connected with the air collecting groove and the air outlet pipe.

[0015] Since the number of heat sinks is large, the torsion spring is adopted, which has a simple structure and high reliability, can provide stable torque, and can make the air outlet pipe reset rapidly after deflection, so as to ensure the accuracy and repeatability of the knocking action.

[0016] Preferably, the driving member two comprises a motor arranged on the collecting pipe and a lead screw mounted on the output end of the motor, the lead screw is arranged on the collecting groove, and the collecting groove and the lead screw are threadedly engaged.

[0017] The rotation of the lead screw is driven by the motor, and the rotation is converted into the linear movement of the collecting groove through the thread engagement, so that the accurate positioning and reciprocating movement of the water removal mechanism are realized. The lead screw transmission has self-locking characteristics, which can ensure that the collecting groove is stably stopped at any position and avoid misoperation.

[0018] Preferably, the projection of the collecting groove in the front-rear direction is completely covered by the collecting groove.

[0019] It ensures that the collecting groove is always within the protection range of the collecting groove during movement, avoids overflow of condensed water or dust from the gap between the collecting groove and the horizontal flat tube, and improves the collection efficiency.

[0020] Preferably, the right end of the collecting groove is provided with a plurality of cleaning rods for removing large dust, and the cleaning rods correspond one-to-one to the gaps.

[0021] The cleaning rods can pre-clean large dust such as willow catkins, leaves, insect corpses, etc. during the movement of the collecting groove, prevent these impurities from blocking the air outlet pipe or affecting the airflow distribution, and improve the adaptability and reliability of the water removal mechanism.

[0022] Preferably, the collecting pipe is provided with a dust collecting groove, when the right end of the collecting groove moves into the dust collecting groove, the cleaning rods push the large dust into the dust collecting groove, and the lower end of the dust collecting groove is provided with a dust discharging hole.

[0023] The dust collecting groove is arranged to collect large impurities, and the large impurities are concentrated and treated through the pushing action of the cleaning rods, avoiding accumulation in the fin gap, and the dust discharging hole facilitates discharge.

[0024] Preferably, a plurality of through holes are formed in the right end surface of the collecting groove, the cleaning rods are slidingly installed in the through holes in the left-right direction, the left end of the cleaning rod is located in the collecting groove, and the left end of the cleaning rod is provided with a ring table for blocking the through hole. A driving member three is arranged on the collecting groove to move the cleaning rod, when the collecting groove moves to the rightmost end, the right end is located in the dust collecting groove, the cleaning rod moves to the left, the ring table is separated from the through hole, and the collecting groove and the dust collecting groove are communicated through the through hole.

[0025] This structure realizes the automatic extension and retraction of the cleaning rod, and makes the collecting groove and the dust collecting groove communicate. When the collecting groove moves to the rightmost end, the driving member three pushes the cleaning rod to move to the left, so that the ring table is separated from the through hole. The airflow in the collecting groove can enter the dust collecting groove through the through hole, and the large impurities accumulated on the cleaning rod can be blown into the dust collecting groove, realizing the centralized cleaning and discharge of the large impurities.

[0026] Preferably, the driving member three comprises an elastic member two arranged between the cleaning rod and the air collecting groove and a baffle one arranged on the cleaning rod, the air collecting groove is provided with a baffle two, the elastic member two is used for keeping the ring table in a state of blocking the through hole, when the air collecting groove just enters the ash collecting groove, the baffle one and the baffle two abut.

[0027] Through the cooperation of the elastic member two and the baffle, the automatic control mechanism of the cleaning rod is realized, when the air collecting groove gradually enters the ash collecting groove, the baffle one and the baffle two abut closely, this action effectively overcomes the resistance generated by the elastic member two, in this process, the force of the baffle is transmitted to the cleaning rod, which drives the displacement of the cleaning rod, and finally leads to the through hole being smoothly opened, so that the airflow can pass through the through hole to clean the right end of the cleaning rod.

[0028] By adopting the above technical scheme, the application has the following beneficial effects:

[0029] 1. The water removal mechanism adopts the cooperative design of the air collecting groove, the air outlet pipe and the collecting groove, and combines the deflection-rebound-knock composite action of the air outlet pipe, so that the double removal mechanism of airflow blowing and mechanical vibration is realized, when the air outlet pipe encounters the edge of the heat dissipation fin during the movement of the water removal mechanism, the air outlet pipe is deflected, the direction of the airflow is changed, the high-pressure airflow directly impacts the surface of the heat dissipation fin at an acute angle, and the condensed water or dust attached to the surface is effectively blown off; after the air outlet pipe passes over the heat dissipation fin, the air outlet pipe rebounds quickly and knocks the heat dissipation fin under the action of the elastic member one (such as a torsional spring), so that vibration is generated and the condensed water or dust is further shaken off, so that the problem of poor removal effect caused by the parallel direction of the airflow and the surface of the heat dissipation fin in the traditional airflow removal is overcome, and the removal rate of the condensed water or dust is greatly improved;

[0030] 2. The water removal mechanism realizes the reciprocating linear motion along the surface of the heat exchanger through the driving member two (such as a motor and a lead screw), so that full-coverage automatic removal can be completed without stopping, the continuous and stable operation of the heat exchanger is ensured, the use efficiency and reliability of the equipment are improved, and at the same time, the fixed connection design of the air collecting groove and the collecting groove ensures the completeness of dust collection, the collecting groove can effectively collect the blown-off condensed water or dust and discharge it through the drain hole, so that the removed condensed water or dust is prevented from gathering around the device;

[0031] 3. The water removal mechanism is also provided with the cleaning rod and the ash collecting groove for pretreatment and collection of large impurities (such as willow catkins, leaves, etc.), the cleaning rod pre-scoops large dust during the movement, and through the cooperation of the baffle one and the baffle two, when the air collecting groove moves into the ash collecting groove, the cleaning rod moves left on the surface of the air collecting groove, so that the ring table is separated from the through hole and the through hole is opened, at this time, the inside of the air collecting groove and the ash collecting groove is in a communication state through the through hole, and then the airflow is used to blow the impurities into the ash collecting groove for centralized discharge, so that the impurities are prevented from blocking the gap between the heat dissipation fins, and the dust removal effect is further optimized.

[0044] DETAILED DESCRIPTION

[0045] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary, and are intended to explain the present application, and cannot be understood as a limitation of the present application. ​​​

[0046] As Figures 1-11 shown, the embodiment of the application is a kind of vehicle mobile agricultural products high-efficiency refrigeration device, including box 1, evaporator 2, condenser 3, water removal mechanism 4, compressor 5, fan 6 and throttling device, box 1 can be placed on the car, it is convenient to use in the field, so as to timely cooling of agricultural products, box 1 is divided into precooling bin and equipment bin by partition, precooling bin is used to place agricultural products, equipment bin is used to place evaporator 2, condenser 3, water removal mechanism 4, compressor 5 and throttling device, water removal mechanism 4 is arranged on condenser 3, for removing the water condensed on the surface of condenser 3, compressor 5 is compressed into high-temperature high-pressure gas from low-temperature low-pressure gaseous refrigerant, is sent into condenser 3 and releases heat to the outside world and is condensed into high-pressure liquid;The liquid is throttled by throttling device (such as expansion valve), and is converted into low-temperature low-pressure vapor-liquid mixture;Subsequently enter evaporator 2, absorb the heat of air (or water) flowing through its surroundings under low pressure and evaporate violently, become low-temperature low-pressure gas again, so that the air temperature drops significantly, realize the cooling of agricultural products;The heat-absorbed refrigerant gas is sucked into compressor 5 again, starting a new cycle, fan 6 is arranged on the left side of condenser 3, for blowing and heat dissipation of condenser 3.

[0047] As Figures 1-11 shown, condenser 3 includes two vertically arranged headers 31, a plurality of parallel flat tubes 32 arranged between the two headers 31, a plurality of heat dissipation fins 33 and water removal mechanism 4. The left and right ends of the flat tubes 32 are fixedly installed on the two headers 31, respectively, a plurality of flat tubes 32 are evenly distributed between the two headers 31 in the vertical direction, and there is a gap between the upper and lower adjacent flat tubes 32, the heat dissipation fins 33 are in the shape of a wave, and a plurality of heat dissipation fins 33 are arranged in a plurality of gaps, respectively, the upper and lower ends of the heat dissipation fins 33 abut the flat tubes 32 at the upper and lower ends, respectively, for conducting heat on the flat tubes 32, thereby increasing the heat exchange area and efficiency.

[0048] The heat medium circulates inside the headers 31 and flat tubes 32, at the same time, air flows through the core structure composed of flat tubes 32 and heat dissipation fins 33 in a transverse manner under the strong driving action of fan 6, and efficient heat exchange is carried out in the process. In order to ensure the removal of condensate water on the surface of the heat exchanger, the water removal mechanism 4 is arranged between the two headers 31, and the water removal mechanism 4 can reciprocate linearly along the surface of the heat exchanger, ensuring that the water removal mechanism 4 can realize full coverage of the surface of the heat exchanger, thereby automatically completing the water removal work on the surface of the heat exchanger, and ensuring the continuous and stable heat exchange efficiency.

[0049] As Figures 1-11As shown, the dewatering mechanism 4 includes an air collecting trough 41, multiple air outlet pipes 42, a collection trough 43, a driving component one, and a driving component two. The air collecting trough 41 is a long, narrow trough structure, and it is slidably mounted on the front end face of the horizontal flow flat pipe 32 in the left-right direction. An air inlet is opened on the front of the air collecting trough 41, and the air inlet is connected to an external air source for collecting and guiding airflow. Multiple air outlet pipes 42 are rotatably mounted at the rear end of the bottom of the air collecting trough 41. The number of air outlet pipes 42 is consistent with the number of gaps between the horizontal flow flat pipes 32, and the air outlet pipes 42 correspond one-to-one with the gaps. The rear end of the air outlet pipes 42 extends into the corresponding gaps to guide the air in the air collecting trough 41 to the heat sink 33. The collection trough 43 is a long, narrow trough structure. It is slidably installed on the rear end face of the horizontal flow flat tube 32 in the left-right direction to collect condensate or dust blown off the heat sink 33. The tops of the collection trough 43 and the air collection trough 41 both extend upwards, beyond the uppermost horizontal flow flat tube 32. The top of the collection trough 43 and the top of the air collection trough 41 are fixedly connected by a connecting plate. A sliding rod is also installed between the two collection tubes 31. The sliding rod passes through the connecting plate to support the air collection trough 41 and the collection trough 43. A driving component 1 is installed on the collection trough 43 to drive the air outlet tube 42 to rotate; a driving component 2 is installed on the collection tube 31 to drive the air collection trough 41 to move.

[0050] In actual operation, the second drive unit starts, causing the air collecting trough 41 to move in the left and right direction. The air collecting trough 41 is connected to an external air source (not shown in the figure). After the airflow enters the air collecting trough 41, it blows towards the heat sink 33 through the air outlet duct 42. When the air collecting trough 41 drives the air outlet duct 42 to pass over the vertical surface of the heat sink 33, the first drive unit controls the air outlet duct 42 to deflect first, so that it blows air towards the surface of the heat sink 33 in the deflection direction, blowing off the attached condensate. After the air outlet duct 42 passes over the vertical surface of the heat sink 33, the first drive unit controls the air outlet duct 42 to deflect quickly in the opposite direction and strike the heat sink 33 in the deflection direction, generating vibration, which further causes the condensate to fall off. The blown-off condensate is collected by the collection tank 43 and discharged through the drain hole at its lower end. The air collecting trough 41 is completely covered by the projection of the collection tank 43 in the front and back direction, ensuring the integrity of the condensate collection.

[0051] like Figure 5 As shown, the internal channel of the air collecting slot 41 gradually narrows from front to back, forming a constricted structure. Since the air outlet area of ​​the air outlet pipe 42 inside the air collecting slot 41 is smaller than the air inlet area on the front of the air collecting slot 41, the airflow enters the air collecting slot 41 and then enters the air outlet pipe 42, forming a high-pressure airflow. The high-pressure airflow is precisely guided to the surface of the heat sink 33 through the air outlet pipe 42, and the direction of the airflow is at an acute angle to the surface of the heat sink 33, making it easier to blow off the condensate on the surface of the heat sink 33.

[0052] like Figures 5-9As shown, the driving member one includes an elastic member one 44, which is a torsion spring, and the two ends of the torsion spring are connected with the air collecting groove 41 and the air outlet pipe 42 respectively. In the natural state, the torsion spring makes the air outlet pipe 42 perpendicular to the vertical plane.

[0053] When the air outlet pipe 42 gradually approaches and finally reaches the edge position of the radiating fin 33 during the moving process, the air outlet pipe 42 will first contact and abut against the edge portion of the radiating fin 33, and then, as the air outlet pipe 42 continues to move along the predetermined path, the air outlet pipe 42 will be subjected to the resistance of the radiating fin 33 due to the obstruction of the radiating fin 33, thereby causing the deflection of the air outlet pipe 42, and at the same time, the torsion spring connected with the air outlet pipe 42 will also be subjected to the corresponding deformation due to the external force, and gradually accumulate energy during the deformation process. When the air outlet pipe 42 successfully passes over the front end portion of the radiating fin 33 abutting against it, the torsion spring previously accumulating energy will rapidly release the stored energy, drive the air outlet pipe 42 to reversely deflect at a faster speed, and finally knock on the radiating fin 33 in the deflection direction. The knocking action will make the radiating fin 33 vibrate, and through the vibration, the condensed water attached to the radiating fin 33 can be effectively caused to fall off, thereby improving the cleaning effect on the radiating fin 33.

[0054] As shown in the figure, Figures 2-4 The driving member two includes a motor 45 and a lead screw 46. The motor 45 is installed on the flow collecting pipe 31, the lead screw 46 is connected with the output end of the motor 45, and is arranged through the air collecting groove 41. The air collecting groove 41 is in threaded engagement with the lead screw 46. When the motor 45 rotates, it drives the lead screw 46 to rotate, thereby driving the air collecting groove 41 to move in the left-right direction.

[0055] As shown in the figure, Figures 3-7 The right end of the air collecting groove 41 is provided with a plurality of cleaning rods 47, the cleaning rods 47 correspond to the gaps one by one, the cleaning rods 47 are at an acute angle with the vertical plane, the front end face of the horizontal flat tube 32 exceeds the front end face of the radiating fin 33, the right end of the cleaning rod 47 extends into the gap, and the right end of the cleaning rod 47 is located between the front end face of the horizontal flat tube 32 and the front end face of the radiating fin 33. The right end of the flow collecting pipe 31 is provided with a dust collecting groove 48. When the air collecting groove 41 moves to the rightmost end, the cleaning rod 47 pushes the large dust into the dust collecting groove 48. The lower end of the dust collecting groove 48 is provided with a dust discharging hole 481 for discharging the large dust. The cleaning rod 47 can shovel the large dust such as willow catkins, leaves, insect corpses, etc. from the front end of the radiating fin 33 in advance during the moving process of the air collecting groove 41. Since the cleaning rod 47 is at an acute angle with the vertical plane, the large dust shovelled will be guided by the cleaning rod 47 to move towards the front, thereby preventing these impurities from being pressed into the gap between the radiating fins 33, and avoiding the gap between the radiating fins 33 from being blocked.

[0056] As shown in the figure, Figures 3-7As shown, a plurality of through holes are formed in the right end surface of the air collecting groove 41, and the cleaning rods 47 are slidingly installed in the through holes in the left-right direction, the left end of the cleaning rod 47 is located in the air collecting groove 41, and the left end is provided with a ring table 471 for plugging the through hole. The air collecting groove 41 is provided with a third driving member for moving the cleaning rod 47 in the left-right direction.

[0057] When the right end of the air collecting groove 41 gradually extends into the interior of the ash collecting groove 48, the edge of the air collecting groove 41 forms a tight sealing state with the left end of the ash collecting groove 48. In this way, the interior space of the ash collecting groove 48 can only communicate with the outside environment through the ash discharging hole 481 at the lower end. When the right end of the air collecting groove 41 just completes the sealing action of the left end of the ash collecting groove 48, the third driving member immediately starts to drive the cleaning rod 47 to move to the left. This movement process makes the ring table 471 on the cleaning rod 47 smoothly separate from the original through hole. At this time, the interior of the air collecting groove 41 and the interior of the ash collecting groove 48 are connected through the through hole. Subsequently, the airflow in the air collecting groove 41 can smoothly enter the interior of the ash collecting groove 48 through the newly formed channel. In this process, the airflow carries enough power to effectively blow off the large impurities accumulated on the surface of the cleaning rod 47, so that they fall into the bottom of the ash collecting groove 48 and are discharged to the outside through the ash discharging hole 481 at the lower end of the ash collecting groove 48, finally realizing the centralized cleaning and discharge of large impurities.

[0058] The third driving member includes a second elastic member 472, a plurality of baffle plates 473 and a baffle plate 482, and the baffle plate 482 is arranged in the ash collecting groove 48. The second elastic member 472 is a spring, and the two ends of the spring are connected with the ring table 471 and the air collecting groove 41 respectively, for keeping the ring table 471 in the state of plugging the through hole. The plurality of baffle plates 473 are arranged at the right ends of the plurality of cleaning rods 47.

[0059] When the right end of the air collecting groove 41 just begins to enter the interior space of the ash collecting groove 48, the baffle plate 473 and the baffle plate 482 tightly abut against each other. As the air collecting groove 41 continues to move to the right along the predetermined direction, the baffle plate 482 begins to push the cleaning rod 47 to move to the left on the surface of the air collecting groove 41. In this process, the ring table 471 gradually separates from the originally nested through hole. At this time, the air collecting groove 41 and the interior of the ash collecting groove 48 are connected through the through hole. The airflow and dust in the air collecting groove 41 can smoothly enter the ash collecting groove 48 through the through hole. In this process, the strong airflow in the air collecting groove 41 effectively blows off the large impurities accumulated on the cleaning rod 47, so that they fall into the interior of the ash collecting groove 48, thereby realizing the centralized cleaning and efficient discharge of large impurities, and ensuring the smooth operation of the system and the cleanliness of the environment.

[0060] As shown in FIG. 6, the air collecting groove 41 is provided with a plurality of through holes, and the cleaning rods 47 are slidingly installed in the through holes in the left-right direction. The left end of the cleaning rod 47 is located in the air collecting groove 41, and the left end is provided with a ring table 471 for plugging the through hole. The air collecting groove 41 is provided with a third driving member for moving the cleaning rod 47 in the left-right direction. Figure 4As shown, the right end of the manifold 31 is provided with a baffle three 49, when the right end of the air collecting groove 41 enters the dust collecting groove 48, the baffle three 49 abuts against the rear end of the air outlet pipe 42, thereby blocking the air outlet of the air outlet pipe 42, and further making the airflow in the air collecting groove 41 only pass through the through hole into the dust collecting groove 48, and the concentrated airflow cleans the large dust in the dust collecting groove 48.

[0061] The working process of the vehicle-mounted mobile type agricultural product high-efficiency refrigeration device is as follows:

[0062] In the initial state, the water removing mechanism 4 is set at the left side of the heat exchanger.When the motor 45 is started, the motor 45 starts to rotate and drives the lead screw 46 to rotate, which in turn drives the air collecting groove 41 to move to the right along the predetermined track. With the right movement of the air collecting groove 41, the airflow in the air collecting groove 41 is strongly blown to the surface of the heat dissipation fin 33 through the air outlet pipe 42. In this process, when the moving path of the air outlet pipe 42 encounters the edge of the heat dissipation fin 33, the air outlet pipe 42 will be deflected accordingly, and this deflection changes the relative angle between the airflow blown by the air outlet pipe 42 and the heat dissipation fin 33, so that the flow direction of the airflow forms an acute angle with the surface of the heat dissipation fin 33, and such an angle setting is more conducive to effectively blowing off the condensed water attached to the surface of the heat dissipation fin 33; at the same time, the torsional spring connected with the air outlet pipe 42 will also be deformed accordingly due to the action of external force, and gradually accumulate energy during the deformation process, when the air outlet pipe 42 successfully passes over the edge of the heat dissipation fin 33, the torsional spring which has accumulated energy will quickly release the stored energy, drive the air outlet pipe 42 to deflect in the opposite direction at a faster speed, and finally knock on the heat dissipation fin 33 in the deflection direction, the knocking action will make the heat dissipation fin 33 vibrate, and through the vibration, the condensed water attached to the heat dissipation fin 33 can be effectively detached, thereby improving the cleaning effect of the heat dissipation fin 33.

[0063] When the right end of the air collecting groove 41 further extends into the interior of the dust collecting groove 48, the baffle one 473 and the baffle two 482 achieve close abutment. With the continuous movement of the air collecting groove 41 to the right, the baffle two 482 exerts a pushing force on the cleaning rod 47, making it move to the left on the air collecting groove 41, and this movement makes the ring table 471 smoothly separate from the original through hole. At this time, the air collecting groove 41 and the interior of the dust collecting groove 48 are connected through the through hole, and the airflow and dust in the air collecting groove 41 can enter the dust collecting groove 48 through the through hole. In this process, the large impurities accumulated on the cleaning rod 47 are also blown off by the strong airflow and enter the dust collecting groove 48, thereby realizing the centralized cleaning and efficient discharge of the large impurities. At the same time, the baffle three 49 closely abuts against the rear end of the air outlet pipe 42, which effectively blocks the air outlet of the air outlet pipe 42, so that the airflow in the air collecting groove 41 can only enter the dust collecting groove 48 through the through hole, and the concentrated airflow thoroughly cleans the large dust in the dust collecting groove 48.

[0064] After the water removal work of the right end is completed, the motor 45 is reversely driven to move the air collecting groove 41 to the left, and the water removal process of the air outlet pipe 42 is repeated to ensure that the condensed water on the entire surface of the heat exchanger is fully and effectively removed.

[0065] Although the embodiments of the present application have been shown and described above, it should be understood by those skilled in the art that the above embodiments are exemplary and cannot be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
