TECHNICAL FIELD
[0001] The utility model relates to agricultural picking device technical field, concretely is a precooling type melon and fruit picking device. BACKGROUND
[0002] There is still a large amount of field heat in fruits and vegetables after picking, and this heat leads to rapid aging of the critical growth of plants, and also causes the loss of fruit and vegetable moisture, ultimately leading to changes in the color of the fruit and vegetable skin and accelerating the speed of fruit and vegetable decay. Therefore, after picking fruits and vegetables, they must be cooled in time to eliminate field heat. Common rapid precooling methods also include air conditioning cold air precooling and cold water spraying or soaking precooling. Cold air precooling requires an air conditioning warehouse and a blower, and cold water spraying or soaking precooling requires a precooling pool and other equipment. However, the above precooling methods are not timely enough and need to be transported to a designated location after picking, which affects the timeliness of precooling, so a picking vehicle with a precooling device that can travel in a field greenhouse can bring more timely precooling effect.
[0003] Some picking vehicles with precooling functions have appeared in the prior art: 1. For example, some picking vehicles are equipped with small air conditioners, but the vehicles are also equipped with compressors, high-power batteries and other air conditioning equipment, which are heavy in weight, high in cost and slow in cooling rate. 2. Cold water pools are placed on picking vehicles, but the cold water pools require a large amount of water, and the overall weight of the vehicle is heavy, making it difficult to walk. SUMMARY
[0004] The utility model aims at providing a precooling type melon and fruit picking device, which is applied to a fruit and vegetable plantation and used for rapid cooling of picked fruits and vegetables to eliminate field heat, improve the quality of fruits and vegetables and increase the shelf life of fruits and vegetables.
[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:
[0006] A precooling type melon and fruit picking device, a fruit and vegetable box and a lower water tray are arranged in the vehicle compartment, a lower water hole is arranged at the bottom of the fruit and vegetable box to lead to the lower water tray below, a plurality of spraying arrays are arranged at the top of the inner cavity of the vehicle compartment, the lower water tray is connected to the spraying arrays through a pipeline and a water pump assembly, and a fruit and vegetable inlet is arranged at the top of the vehicle compartment.
[0007] After picking fruits and vegetables, workers put the fruits and vegetables into the circular fruit and vegetable inlet at the top, and the fruits and vegetables are stored in the fruit and vegetable box; the fruits and vegetables are cooled by circulating spraying water, the spraying water is driven to circulate by the water pump assembly, the water pump assembly includes a water pump and a small battery that provides power for the water pump, and the cold water is sprayed from the top to the bottom through the spray heads of the spraying arrays at the top, so that the fruits and vegetables at the top and the bottom can be uniformly cooled.
[0008] The lower water tray edge is stepped, the lower step plane supports the fruit and vegetable box bottom surface, the fruit and vegetable box can be pulled out from the rear of the vehicle compartment in a drawer type, and the lower water tray is fixed in the vehicle compartment inner cavity.
[0009] The fruit and vegetable box middle part is provided with an inclined surface body below the fruit and vegetable inlet position, the inclined surface body forms an inclined slide way, so that the input fruit and vegetable can slide to the two sides along the inclined surface, without free falling and colliding to cause damage, and the fruit and vegetable surface intact rate is improved; the inclined surface body also divides the fruit and vegetable compartment into front and rear two parts, and workers can select to deviate the fruit and vegetable to any end compartment space according to the empty rate of the front and rear spaces.
[0010] The vehicle compartment inner cavity top part is provided with a disc-shaped spray array, and the spray array is staggered with the inclined surface body position.
[0011] The spray array matching position is provided with a refrigerant above, the refrigerant is in contact with the pipeline surface of the spray array, and a refrigerant cover is arranged above the refrigerant.
[0012] The lower water tray is provided with a filter screen near the water outlet pipe end.
[0013] The vehicle compartment bottom part is provided with a plurality of traveling wheels.
[0014] Advantages of the utility model
[0015] (1) The utility model is applied to a fruit and vegetable plantation, is used for rapid cooling of fruit and vegetable after instant picking, eliminates field heat, improves fruit and vegetable quality, and prolongs the shelf life of fruit and vegetable.
[0016] (2) The utility model uses a refrigerant to provide the cooling capacity of cooling water, so that a refrigeration device does not need to be arranged in the device, the refrigerant can be updated or taken out at any time, and the utility model is very flexible.
[0017] (3) The fruit and vegetable box guides through the inclined surface body, prevents the fruit and vegetable free fall from colliding with the surface, and improves the surface quality of the fruit and vegetable. BRIEF DESCRIPTION OF DRAWINGS
