[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0036] Combination Figure 1-4 As shown, an embodiment of the present disclosure provides an agricultural vehicle air-conditioning evaporator drainage device, comprising: an evaporator 100 and a shell mounted on the outside of the evaporator 100, the shell being composed of a rectangular bottom plate 101 and side walls 102 forming a cavity around the bottom plate 101, the shell bottom plate 101 being bent in the middle and inclined at both ends upward, and the side edges of the bottom plate 101 are connected to the side walls 102, the shell side walls 102 are connected with drainage holes 103, and the drainage holes 103 are arranged on the side walls 102 at the lowest end of the bottom plate 101.

[0037] By adopting the drainage device of the agricultural vehicle air-conditioning evaporator 100 provided in the embodiment of the present disclosure, heat exchange can be carried out through the evaporator 100. Condensed water will condense on the evaporator 100 during the heat exchange. The outside of the evaporator 100 can surround and wrap the evaporator 100, and air can enter from one side of the shell and flow through the evaporator 100 and then be discharged from the other side, thereby completing the heat exchange work. However, the condensed water on the evaporator 100 will remain in the shell, and the shell is composed of a bottom plate 101 and a side wall 102. The fallen condensed water will remain on the bottom plate 101. The condensed water can be accumulated in the low-lying part of the bend through the bend on the bottom plate 101, and the condensed water can be discharged through the drainage hole 103 of the bottom plate 101 through the side wall 102, and the drainage hole 103 is set on the side wall 102 at the lowest end of the bottom, which can facilitate the discharge of the condensed water.

[0038] Optionally, a carrying plate 200 for supporting the evaporator 100 is provided inside the shell, and the carrying plate 200 is arranged on the upper part of the bottom plate 101 .

[0039] In this way, by placing a supporting plate 200 inside the shell, the evaporator 100 can be supported. Since most agricultural machinery works in farmlands and other uneven roads, and has poor shock absorption effect like a vehicle, the supporting plate 200 can stably support the evaporator 100, and long-term vibration will affect the stability of the evaporator 100.

[0040] Optionally, a plurality of drain holes 201 for separating condensed water from the evaporator 100 are provided on the supporting plate 200 .

[0041] In addition, by arranging a plurality of drain holes 201 on the upper part of the supporting plate 200, the condensed water condensed on the evaporator 100 can be discharged, and the condensed water can directly fall onto the bottom plate 101 at the bottom of the supporting plate 200, and then be discharged from the drain holes 103 on the side of the bottom plate 101, thereby preventing the condensed water from accumulating at the bottom of the evaporator 100 and preventing the condenser from rusting due to water accumulation in the condenser.

[0042] Optionally, the bottom plate 101 is a V-shaped plate structure along the length direction.

[0043] In this way, by setting the bottom plate 101 as a V-shaped structure, it is convenient to collect the fallen condensed water, so that the condensed water can flow into the lowest end of the bottom plate 101 and then be discharged from the drainage hole 103.

[0044] Optionally, the bottom plate 101 is an inverted V-shaped plate structure along the width direction, and the bottom plate 101 is bent to form a groove on the side of the bottom plate 101.

[0045] In this way, the bottom plate 101 is a V-shaped structure, which allows condensed water to flow to both ends of the bottom plate 101. The lowest end of the bottom plate 101 is formed between the bottom plate 101 and the side wall 102. Water flows from the middle of the bottom plate 101 to both sides, and then can be drained from the drain outlet of the side wall 102, thereby preventing water accumulation on the bottom plate 101.

[0046] Optionally, the bottom plate 101 is tilted upward from both ends to the middle to form a V-shaped tilted portion 104, and the tilted portion 104 is tilted downward from the middle to both ends. Both ends of the bottom plate 101 are tilted by the tilted portion 104 to form two lowest ends.

[0047] In this way, by providing an inclined portion 104 at the bottom of the V-shaped bottom plate 101, the bottom plate 101 is a V-shaped bending structure, and along the bending line of the bottom plate 101, it is inclined upward from both ends to the middle to form the inclined portion 104, and the lowest end of the inclined portion 104 is arranged toward the side wall 102, and the lowest end of the inclined portion 104 is arranged at the bending part of the V-shaped bottom plate 101, so that two lowest points can be formed at both ends of the bottom plate 101, and the drainage holes on the side walls 102 on the sides of the two lowest points can discharge the condensed water on the bottom plate 101, which can prevent the condensed water from accumulating on the bottom plate 101, and the inclined portion 104 is inclined downward from the middle to both ends, and the inclined portion 104 is two inclined surfaces, which can prevent the problem of a high overall height of a single inclined surface. Through the two inclined surfaces, when the inclination angle is the same, it can be ensured that the height after inclination is half of the single inclined surface.

[0048] Optionally, the drainage hole 103 is provided on the side wall 102 at the lowest end of the bottom plate 101 .

[0049] In this way, the drainage hole 103 is arranged on the side wall 102 at the lowest end of the bottom plate 101, so that the condensed water accumulated at the lowest end of the bottom plate 101 can be discharged through the drainage hole 103, so that the condensed water can be better discharged.

[0050] Optionally, there are two drainage holes 103 , which are respectively disposed on the side wall 102 at the lowest end of the bottom plate 101 .

[0051] In this way, there are two drainage holes 103, which can conveniently discharge the condensed water at the lowest ends of the two bottom plates 101, and by arranging the drainage holes 103 on the side walls 102, the drainage holes 103 can be arranged on both sides of the side walls 102, thus preventing the problem of the shell height being too high.

[0052] Optionally, the inclined portion 104 is a planar structure bent toward two ends.

[0053] In this way, the inclined portion 104 is a planar structure with a bent middle portion, which can facilitate the flow of condensed water.

[0054] Optionally, the evaporator 100 is vertically disposed on the supporting plate 200 , and one end of the evaporator 100 passes through the outside of the side wall 102 .

[0055] In this way, the evaporator 100 is vertically arranged on the supporting plate 200, so that the supporting plate 200 can better support the evaporator 100, and one end of the pipe of the evaporator 100 extends out of the side wall 102, so that the evaporator 100 can be connected to the compressor.
