DETAILED DESCRIPTION

[0022] Figure 1 It is the best embodiment of the utility model, and the following Figures 1 to 3 The utility model is further described.

[0023] Embodiment 1:

[0024] like Figure 1 As shown, a vehicle-mounted low-temperature milking and milk storage machine includes a transfer cart 19, and the surface of the transfer cart 19 is a bearing surface. In this vehicle-mounted low-temperature milking and milk storage machine, the transfer cart 19 is implemented by a trolley, and an armrest 5 is arranged at the rear end of the surface of the transfer cart 19, a bottom wheel 16 is arranged at the bottom of the bearing surface of the transfer cart 19, and a universal wheel 12 is arranged at the front end of the bottom of the bearing surface of the transfer cart 19.

[0025] A milk storage tank 18 is arranged at one end of the bearing surface close to the handrail 5. The milk storage tank 18 is placed vertically. A support column 7 is erected in front of the milk storage tank 18. A bracket 2 is arranged on the top of the support column 7. The bottom of the bracket 2 is rotatably mounted on the top of the support column 7. The upper end of the bracket 2 is bent to form an inclined support rod. Since the bottom of the bracket 2 is rotatably connected to the support column 7, the support rod can swing back and forth on the surface of the support column 7.

[0026] A vacuum pump 15 is provided on the side of the support 7 facing away from the milk storage tank 18. The vacuum pump 15 is fixed on the surface of the carrying surface of the transfer vehicle 19. A baffle 14 is provided on the side of the vacuum pump 15. A vacuum tank 9 is also provided on the upper part of the support 7. The vacuum tank 9 is located on the upper part of the vacuum pump 15. The vacuum port of the vacuum pump 15 is connected to the vacuum tank 9 through a pipeline. The pipeline leading from the vacuum pump 15 protrudes from the bottom surface of the vacuum tank 9 after entering the vacuum tank 9, so as to prevent the liquid mixed in the vacuum tank 9 from flowing back into the vacuum pump 15 and causing damage to the vacuum pump 15. A control box 6 is provided on one side of the support 7.

[0027] A pulser 8 is provided on the top of the vacuum tank 9, and a pulse tube 10 is led out from the port of the pulser 8, and the pulse tube 10 is connected to the milking cup group 3. A hanging ring 4 is provided in the middle of the above-mentioned support rod, and a hanging hook is provided at the end of the support rod, and the milking cup group 3 is hung at the hanging hook. A milk extraction pipeline 1 is led out from the milking cup group 3, and the milk extraction pipeline 1 is connected to the milk storage tank 18. The milk extraction pipeline 1 and the pulse tube 10 are simultaneously hung through the hanging ring 4 to prevent the milk extraction pipeline 1 and the pulse tube 10 from falling to the ground. A pipeline is also led out from the side of the vacuum tank 9, and the other end of the pipeline is simultaneously connected to the milk storage tank 18. The pipeline led out from the vacuum tank 9 is installed at the top cover of the milk storage tank 18, and the milk extraction pipeline 1 is simultaneously installed at the top cover of the milk storage tank 18.

[0028] A refrigeration unit 11 is arranged at the front end of the carrying surface of the transfer vehicle 19, a refrigerant pipeline 13 is led out from the refrigeration unit 11, a coil 17 is arranged in the milk storage tank 18, and the refrigerant pipeline 13 is connected to the coil 17. The working principle of the refrigeration unit 11 is the same as the refrigeration principle in the prior art. Taking an air conditioner as an example, the refrigeration unit 11 is equivalent to the external unit of the air conditioner.

[0029] A compressor, a condenser and an expansion valve are provided in the refrigeration unit 11. The compressor compresses the gaseous refrigerant (such as Freon) into a high-temperature and high-pressure gas. The high-temperature and high-pressure gaseous refrigerant passes through the condenser in the refrigeration unit 11 and becomes a liquid refrigerant at room temperature and high pressure. The liquid refrigerant at room temperature and high pressure is connected to the coil 17 through the refrigerant pipeline 13. The coil 17 is equivalent to the evaporator of the air conditioner. The liquid refrigerant at room temperature and high pressure is vaporized in the coil 17 and becomes a gaseous low-temperature refrigerant to cool the fresh milk in the milk storage tank 18. After absorbing heat in the coil 17, the refrigerant returns to the refrigeration unit 11 through the refrigerant pipeline 13 and is compressed again, and so on.

[0030] The specific working process and working principle are as follows: the staff pushes the vehicle-mounted low-temperature milking and milk storage machine to the milking place, and docks it with the cow (or goat) after removing the milking cup group 3. Turn on the vacuum pump 15, and after the vacuum pump 15 works, a negative pressure is formed in the vacuum tank 19. The pulser 7 is connected to the vacuum tank 9. The pulser 7 is used to control the suction rate of the milking cup group 3 to ensure the health of the milk-producing animal. The principle of the pulser 7 and the milking cup group 3 to achieve milk extraction belongs to the common knowledge in the field and will not be repeated here.

[0031] Since the milk storage tank 18 is connected to the vacuum tank 19 through a pipeline, negative pressure is formed in the milk storage tank 18 through the vacuum tank 19. Since the milk extraction pipeline 1 is connected to the milk storage tank 18, the fresh milk extracted through the milking cup group 3 is output through the milk extraction pipeline 1 and flows into the milk storage tank 18, forming a milk extraction cycle.

[0032] At the same time, the refrigeration unit 11 is working, and the fresh milk in the milk storage tank 18 is cooled through the coil 17 according to the above principle to prevent the fresh milk from deteriorating.

[0033] Embodiment 2:

[0034] like Figure 2~3 As shown, in this embodiment, the same as in Embodiment 1: a milk storage tank 18 and a refrigeration unit 11 are respectively arranged at the front end and the rear end of the carrying surface of the transfer vehicle 19.

[0035] The difference from the first embodiment is that the milk storage tank 18 in the present embodiment is horizontally arranged on the surface of the transfer vehicle 19, and its capacity is much larger than that of the milk storage tank 18 in the first embodiment. The refrigerant pipeline 13 drawn from the refrigeration unit 11 extends along the edge of the transfer vehicle 19 to the end surface of the milk storage tank 18 and then connects to the milk storage tank 18 and connects to the coil 17 ( Figure 2~3 not shown).

[0036] In this embodiment, a fixing frame is provided on the surface of the carrying surface of the transfer vehicle 19, the fixing frame is located between the milk storage tank 18 and the refrigeration unit 11, a delivery pump 22 is provided at the lower part of the fixing frame, an intermediate milk tank 21 is provided at one side of the lower part of the fixing frame, the inlet of the delivery pump 22 is connected to the intermediate milk tank 21 through a pipeline, and the outlet of the delivery pump 22 is connected to the milk storage tank 18 through a pipeline. A control box 20 is also provided at one side of the fixing frame.

[0037] The vacuum pump 15 is fixed on the top of the milk storage tank 18. The vacuum port of the vacuum pump 15 is connected to the vacuum tank 9 through a pipeline. The vacuum tank 9 is fixed on the upper surface of the fixing frame. The pipeline drawn from the side of the vacuum tank 9 is connected to the middle milk tank 21. The pulser 8 installed on the top of the vacuum tank 9 is connected to the milking cup group 3 through the pulse tube 10. The milk extraction pipeline 1 drawn from the milking cup group 3 is connected to the middle milk tank 21.

[0038] The support 2 is directly fixed on the surface of the carrying surface of the transfer vehicle 19, and the support 2 is located between the fixing frame and the milk storage tank 18. The milk extraction pipeline 1 and the pulse tube 10 are hung on the support 2 in the same manner as in the first embodiment.

[0039] The specific working process and working principle are as follows:

[0040] The staff pushes the vehicle-mounted low-temperature milking and milk storage machine to the milking place, and docks it with the cow (or goat) after removing the milking cup group 3. The vacuum pump 15 is turned on. After the vacuum pump 15 works, negative pressure is formed in the vacuum tank 19. The pulser 7 is connected to the vacuum tank 9. The pulser 7 is connected to the milking cup group 3 through the pulse tube 10 to extract milk.

[0041] Since the volume of the milk storage tank 18 in this embodiment is much larger than that of the milk storage tank 18 in Embodiment 1, it is difficult to form a negative pressure in the milk storage tank 18 through the vacuum tank 9 and realize milk extraction through the milk extraction pipeline 1. Therefore, in this embodiment, an intermediate milk tank 21 is provided. Since the volume of the intermediate milk tank 21 is small, it is easier to form a negative pressure in the intermediate milk tank 21 through the vacuum tank 9, and the fresh milk extracted from the milking cup group 3 is firstly pumped into the intermediate milk tank 21 through the milk extraction pipeline 1, and then the fresh milk in the intermediate milk tank 21 is sent to the milk storage tank 18 through the delivery pump 22. The refrigeration unit 11 cools the fresh milk in the milk storage tank 18 with the same working principle to prevent the fresh milk from deteriorating.

[0042] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
