Description

Technical Field

[0001] This utility model relates to the technical field of dairy cow milking equipment, specifically to a cow loading protection device for a rotary milking machine. Background Technology

[0002] With the advancement of science and technology, manual milking has been gradually replaced by mechanical milking machines, which has led to the emergence of rotary milking equipment. Rotary milking machines can milk multiple cows at the same time, greatly improving milking efficiency.

[0003] However, the loading device of the existing rotary milking machine can cause cows to be squeezed between the railing and the turntable due to crowding or premature entry, resulting in injury to the cows. Utility Model Content

[0004] In view of this, the problem to be solved by this utility model is to provide a cow protection device for a rotary milking machine.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A cow protection device for a rotary milking machine includes several guide frames arranged side by side, with gaps between adjacent guide frames for cows to pass through, and gates rotatably connected to the lateral ends of the guide frames.

[0007] The photoelectric sensor, which is electrically connected to the electrical control cabinet, is installed on the guide frame. The reflector of the photoelectric sensor is installed on the gate. The photoelectric sensor is used to detect the relative rotational position between the gate and the guide frame. When the reflector is driven out of the detection range of the photoelectric sensor by the gate, the photoelectric sensor controls the electrical control cabinet to stop running.

[0008] The guide frame has an extended positioning plate at the top and bottom of its horizontal end. Both sets of extended positioning plates have columnar supports installed at their facing ends. The gate has a tubular structure in its vertical direction, and the two ends of the tubular structure are respectively fitted and connected to the columnar supports.

[0009] The outer positioning plate is also constructed with a strip slot for inserting photoelectric sensors. Ear plates are fixedly sleeved on the outer periphery of the tubular body, and reflectors are fixedly installed on the ear plates. When the guide frame is flush with the gate, the reflector is located directly below the strip slot.

[0010] The guide frame and the ear plate are connected by an elastic reset member.

[0011] The guide frame is also fixedly provided with a screw bracket, and both ends of the screw bracket are threaded with screws. Both ends of the screw and the ear plate are fixedly connected with chains, and the chains of the screw and the ear plate are connected by tension spring hooks.

[0012] The outer side of the lateral end of the guide frame is also provided with abutments for abutting against the gate.

[0013] The advantages and positive effects of this utility model are:

[0014] The guide frame is equipped with a gate and a photoelectric sensor. A reflector corresponding to the photoelectric sensor is mounted on the gate. When the guide frame is flush with the gate, the rays emitted by the photoelectric sensor are reflected by the reflector and received by the receiver, preventing cows from entering through the gate. The control cabinet continuously drives the turntable to rotate. When a cow pushes the gate prematurely or due to crowding, an angle forms between the gate and the guide frame. Consequently, the reflector shifts with the gate. When the reflector moves out of the photoelectric sensor's detection range due to the gate, the sensor sends a signal to the controller, which then stops the control cabinet, thus preventing cows from being squeezed between the gate and the turntable and causing injury.

[0024] like Figures 1 to 4 As shown, this utility model provides a cow protection device for a rotary milking machine, including several guide frames 10 arranged side by side. The gap between adjacent guide frames 10 is used for cows to pass through. A gate 9 is rotatably connected to the lateral end of the guide frame 10. In the initial state, the guide frame 10 is flush with the gate 9, and the gate 9 is closed relative to the turntable. When the turntable is stationary, after the cow passes through the gap between adjacent guide frames 10, it pushes the gate 9 to enter the cow position on the turntable.

[0025] A photoelectric sensor electrically connected to the control cabinet is installed on the guide frame 10. The reflector 11 of the photoelectric sensor is installed on the gate 9. The photoelectric sensor includes a transmitter and a receiver. When the guide frame 10 is flush with the gate 9, the rays emitted by the transmitter of the photoelectric sensor are reflected by the reflector 11 and received by the receiver. This means that no cows are entering through the gate 9. The control cabinet continues to drive the turntable to rotate. When the gate 9 rotates relative to the guide frame 10 and the control cabinet is in operation, it means that a cow has pushed the gate 9 in advance or that the cow has pushed the gate 9 due to crowding or other reasons. An angle appears between the gate 9 and the guide frame 10. Correspondingly, the reflector 11 moves with the gate 9. When the reflector 11 is driven out of the detection range of the photoelectric sensor by the gate 9 (the reflector 11 moves completely out of the range of the transmitter, and the receiver cannot receive the rays reflected by the reflector 11), the photoelectric sensor sends a signal to the controller. The controller controls the control cabinet to stop operating, thereby preventing the cows from being squeezed between the gate 9 and the turntable and causing injury to the cows.

[0026] Specifically, the guide frame 10 includes a seamless steel pipe 1, a square tube 2, and a column 3. Three columns 3 are erected and arranged horizontally. One seamless steel pipe 1 and three square tubes 2 are arranged horizontally, passing through the column 3 located in the middle. Both ends are fixedly connected to the columns 3 on both sides. The seamless steel pipe 1 is located above the square tubes 2 to increase the structural strength of the entire guide frame 10. A partition is installed between adjacent square tubes 2.

[0027] The guide frame 10 has an extended positioning plate 7 at both the top and bottom of its lateral end. The extended positioning plate 7 is detachably connected to the guide frame 10 by bolts. The extended positioning plate 7 extends outward along the lateral end of the guide frame 10. Columnar support bodies 71 are vertically installed on the facing ends of both sets of extended positioning plates 7 to provide support for the rotation of the gate 9. A tubular body 91 is constructed vertically on the gate 9. The two sets of columnar support bodies 71 are respectively connected to the two ends of the tubular body 91 in the vertical direction, thereby realizing the relative rotation of the gate 9 relative to the guide frame 10.

[0028] Specifically, the outer positioning plate 7 is also constructed with a strip slot 72 for inserting a photoelectric sensor. An ear plate 92 is fixedly sleeved on the outer periphery of the tubular body 91, and a reflector plate 11 is fixedly installed on the ear plate 92. When the guide frame 10 is flush with the gate 9 (when the gate 9 is closed relative to the turntable), the reflector plate 11 is located directly below the strip slot 72, so that the rays emitted by the emitting end of the photoelectric sensor are reflected by the reflector plate 11 and received by the receiving end.

[0029] Specifically, the guide frame 10 and the ear plate 92 are connected by an elastic reset member. On the one hand, this can dampen the rotation of the gate 9 relative to the guide frame 10, and prevent external forces such as vibration caused by the cow hitting the guide frame 10 from causing the gate 9 to rotate relative to the guide frame 10, thereby causing the electrical control cabinet to stop erroneously.

[0030] Specifically, a screw bracket 4 is also fixed on the guide frame 10. Screws 5 are threaded to both ends of the screw bracket 4. Chains are fixed to both ends of the screws 5 and the ear plate 92. The chain of the screws 5 and the chain of the ear plate 92 are connected by a tension spring 6.

[0031] The screw bracket 4 and the ear plate 92 have the same width and their shapes are symmetrical about the center. Therefore, when the two sets of screws 5 are in the same position on the screw bracket 4, the gate 9 is elastically taut relative to the guide frame 10. The relative distance between the gate 9 and the screw bracket 4 can be adjusted by adjusting the position of the two sets of screws 5 on the screw bracket 4, thereby adjusting the degree of elastic tension to meet different working conditions. Furthermore, the tension at both ends of the gate 9 can be different by adjusting the position of one set of screws 5 on the screw bracket 4, thereby adjusting the initial position of the gate 9 relative to the guide frame 10.

[0032] Specifically, the outer side of the lateral end of the guide frame 10 is also provided with a foot 101 for abutting against the gate 9. In this embodiment, the foot 101 is set vertically relative to the guide frame 10, thereby limiting the rotation angle of the gate 9 to ninety degrees, so as to avoid the tension spring 6 from separating from the screw 5 of the guide frame 10 or the ear plate 92 of the gate 9 due to excessive rotation angle.

[0033] The working principle and process of this utility model are as follows:

[0034] Initially, when the guide frame 10 is flush with the gate 9, the rays emitted by the photoelectric sensor are reflected by the reflector 11 and received by the receiver. This means that no cows are entering through the gate 9. The control cabinet continues to drive the turntable to rotate. When the gate 9 rotates relative to the guide frame 10 and the control cabinet is in operation, it means that a cow has pushed the gate 9 prematurely or due to crowding, causing an angle to form between the gate 9 and the guide frame 10. Correspondingly, the reflector 11 moves with the gate 9. When the reflector 11 is moved out of the range of the emitting end by the gate 9 and the receiving end can no longer receive the rays reflected by the reflector 11, the photoelectric sensor sends a signal to the controller, and the controller controls the electrical control cabinet to stop running. After the cow is safely brought out, due to the lack of pushing force from the cow, the gate 9 rotates relative to the guide frame 10 under the action of the tension spring 6 until it returns to a level position. The rays emitted by the emitting end of the photoelectric sensor can be received by the receiving end after being reflected by the reflector 11, and then the electrical control cabinet continues to drive the turntable to rotate.

[0035] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
