Description

Technical Field

[0001] The utility model relates to the technical field of livestock breeding, in particular to a heating type feeding passage for dairy cows. Background Art

[0002] An important link in dairy cow breeding is feed processing. In winter, the temperature is relatively low, and the feed for feeding is too cold in cold weather, resulting in the problem that dairy cows do not eat. Moreover, eating cold feed may cause discomfort to dairy cows and affect the milk yield of dairy cows. Therefore, heating the feed in winter is crucial.

[0003] Arc-shaped grooves are usually arranged on both sides of the aisle in the cowshed. The arc-shaped grooves are adjacent to the cow guardrail. The arc-shaped grooves form both a feeding trough and a water trough. The feed is usually placed on the aisle. During feeding, the feed is manually dialed into the arc-shaped groove by workers. The dairy cow can stretch its head out of the guardrail to eat the feed. After the feed is fed, the feeding trough is cleaned, and drinking water can be added for the cows to drink after cleaning. In the actual use process, the following problems are mainly encountered: 1. The arc-shaped groove is made of cement, resulting in a rough and uneven inner surface of the arc-shaped groove. When the dairy cow licks the feed, it is easy to hurt its tongue, affecting the feeding amount of the cow, and at the same time, it is not conducive to the effective cleaning of the forage; 2. When used in winter, the surface of the feeding trough made of cement is icy cold, and the dairy cow is reluctant to lick the feeding trough, which affects the feeding amount of the cow and is not conducive to milk production of the dairy cow.

[0004] A feeding trough heating device for livestock breeding with the patent number CN207692679U includes a heating box. A movable box is fixedly connected to the bottom of the heating box. Heaters are arranged on both sides of the inner cavity of the heating box, and heating wires are arranged in the heaters. A feeding trough body is arranged in the inner cavity of the heating box. Slide rods are arranged on both sides of the bottom of the feeding trough body. A slide rail adapted to the slide rods is opened at the bottom of the inner cavity of the heating box. A rotating rod is fixedly connected to the center of the bottom of the feeding trough body. The bottom of the rotating rod penetrates through the heating box and the movable box and extends into the inner cavity of the movable box. The connection between the bottom of the rotating rod and the movable box is movably connected through a movable base. A driven wheel is sleeved on the bottom surface of the rotating rod. The utility model can heat the food in the feeding trough through the mutual cooperation of the heating box, the heater, the driven wheel, the rotating rod, the movable base, the belt, the motor, the driving wheel, the slide rod and the slide rail, so that the food is more convenient to heat. However, in actual application, due to the large size and heavy weight of dairy cows, the feeding trough is easily damaged. After the feeding trough is damaged, the heating wire is exposed in the air, which is likely to cause electric shock due to contact. At the same time, the structure is complex and the cost is high. Content of the Utility Model

[0005] The purpose of the utility model is to provide a heating type feeding passage for dairy cows. The heating type feeding passage has a simple structure, can heat the food and water, is not only safe and reliable, but also does not cause cross-infection among dairy cows, and improves the milk yield and the quality of raw milk of dairy cows.

[0006] To achieve the above object, the present utility model adopts the following technical solutions:

[0007] A heated feeding passage for dairy cows, comprising a feeding trough, a first drainage pipeline, a second drainage pipeline, a first chamber and a heat exchange system. The first drainage pipeline, the first chamber, the second drainage pipeline and the heat exchange system are connected end to end to form a closed loop; the liquid heated by the heat exchange system flows into the first chamber through the first drainage pipeline and exchanges heat with the liquid in the first chamber, then flows out of the first chamber through the second drainage pipeline and returns to the heat exchange system; the first chamber provides heat for the feeding trough.

[0008] Preferably, a top plate is provided at the top of the first chamber, a through groove is provided along the length direction of the top plate, and a feeding trough is correspondingly placed in the through groove. The feeding trough includes a drinking trough and a feed trough.

[0009] Preferably, a plurality of sliding rails are provided at the bottom of the through groove, and sliding blocks are provided at the bottoms of the drinking trough and the feed trough and are matched with the sliding rails. The sliding blocks are clamped on the sliding rails and can move along the sliding rails.

[0010] Preferably, an embedded groove is provided on the sliding rail, a long strip-shaped mounting hole is provided on the sliding block, the mounting hole is a through hole, and a clamping member is inserted in the mounting hole. The clamping member is in a T shape and can be clamped in the embedded groove.

[0011] Preferably, a first communication hole is provided on the left side of the first chamber, and a second communication hole is provided on the right side of the first chamber. The first drainage pipeline is inserted into the first communication hole and is matched with the first communication hole, and the second drainage pipeline is inserted into the second communication hole and is matched with the second communication hole.

[0012] Preferably, the heat exchange system includes a housing, a second chamber is provided inside the housing, a combustion chamber is provided in the second chamber, an intake pipe is connected to the bottom of the combustion chamber, the intake pipe passes through the housing and an intake valve is provided at the end; a circulation pipeline is wound outside the combustion chamber, the circulation pipeline is connected to the first chamber through the first drainage pipeline, a water pump is connected to the other end of the first chamber, and the other end of the water pump is connected to the other side of the circulation pipeline through the second drainage pipeline.

[0013] Preferably, a second exhaust pipe is provided at the top of the combustion chamber, and the other end of the second exhaust pipe passes through the housing.

[0014] Preferably, the heat exchange system includes an electric heating wire and a metal pipe. One end of the metal pipe is connected to the first drainage pipeline, the other end of the metal pipe is connected to the second drainage pipeline, an electric heating wire is wrapped around the periphery of the metal pipe, the electric heating wire heats the liquid in the metal pipe, and a third chamber is provided outside the electric heating wire.

[0016] Preferably, a water inlet and a water outlet are provided at the bottom of the first chamber; a first exhaust pipe is provided at the top of the first chamber.

[0017] In the above technical solution, by connecting the first drainage pipeline, the first chamber, the second drainage pipeline and the heat exchange system end to end to form a closed loop, the liquid heated by the heat exchange system flows into the first chamber through the first drainage pipeline, so that the temperature of the liquid in the first chamber rises. Since the outer walls of the first chamber are all metal plates, the liquid in the first chamber with increased temperature performs heat exchange on the metal plates to increase the temperature of the metal plates. At the same time, after the temperature of the liquid in the first chamber decreases, it flows to the heat exchange system through the second drainage pipeline and is heated again by the heat exchange system, repeating the cycle, and finally keeping the temperature of the liquid in the first chamber stable.

[0018] By spraying paint on the inner walls of the metal plates, the liquid in the first chamber will not oxidize the metal plates, increasing the service life. By providing grooves on the top plate, a drinking trough and a feeding trough are correspondingly placed in the grooves. During cleaning, the feeding trough and the drinking trough can be taken out for disinfection and cleaning, which is convenient to use. Further, a number of slide rails are provided in the grooves, and sliders matching the slide rails are provided at the bottoms of the drinking trough and the feeding trough. The sliders can be clamped on the slide rails and move along the slide rails. During cleaning, the sliders can be slid to disengage from the slide rails, which is convenient and fast. Each cow corresponds to a drinking trough and a feeding trough, avoiding cross-infection in diet. Further, embedding grooves are provided on the slide rails, and long-strip installation holes are provided on the sliders. The installation holes are through holes, and clamping members are inserted into the installation holes. The clamping members are in a T shape. When the sliders slide to the designated positions, the clamping members extend downward into the embedding grooves and fix the sliders on the slide rails. When it is necessary to remove the drinking trough or the feeding trough, only the clamping members need to be lifted upward, and the corresponding sliders can be slid along the slide rails.

[0019] The gas is controlled to enter the combustion chamber through the intake valve to heat the liquid in the circulation pipeline wound around the outer periphery of the combustion chamber, and the change of the water temperature can be controlled. The circulation pipeline is connected to the first chamber through the first drainage pipeline, the other end of the first chamber is connected to the water pump, and the other end of the water pump is connected to the circulation pipeline through the second drainage pipeline to form a closed loop, so that the liquid flowing through the first chamber continues to travel to the circulation pipeline through the water pump for heating until the liquid in the first chamber reaches a certain temperature, and heat exchange is carried out between the liquid in the first chamber and the food in the food trough and the water in the drinking trough, so that the water and food consumed by the cows will not be too cold. Or directly heat the metal pipe through the heating wire. After the metal pipe is heated, the heat drives the liquid in the metal pipe to rise in temperature. The power provided by the water pump makes the heated liquid flow into the first chamber, so that the temperature of the liquid in the first chamber rises, and thus the temperature in the metal groove rises.

At the same time, the temperature of the liquid in the first chamber 2 decreases and then flows to the heat exchange system 4 through the second drainage pipeline 3, and is heated again by the heat exchange system 4. This cycle repeats, and finally the temperature of the liquid in the first chamber 2 is kept stable. In this embodiment, paint is sprayed on the inner wall of the metal plate, and the liquid in the first chamber 2 will not oxidize the metal plate, increasing the service life.
