Description

Technical Field

[0001] This utility model relates to the field of dairy cow breeding and testing technology, and in particular to a device for testing the breeding of replacement dairy cows. Background Technology

[0002] To ensure milk production efficiency, selective breeding of dairy cows is necessary, and determining the optimal mating time is crucial. There are various methods for determining the mating time, one of which is detecting the state of mucus discharge from the cow's vulva. Existing Chinese patent application number 202420603239.7 discloses a dairy cow mucus detection device, comprising: a first gripping unit, a second gripping unit, the second gripping unit being disposed on one side of the first gripping unit for use with the first gripping unit for a user to hold; a first clamping arm unit, the second end of the first clamping arm unit being connected to the first end of the first gripping unit; and a second clamping arm unit, the second end of the second clamping arm unit being connected to the first end of the second gripping unit, and connected to the... The first clamping arm unit is hinged and used to cooperate with the first clamping arm unit to form an open or closed state under the action of the first gripping unit and the second gripping unit; a first clamping unit is disposed at the first end of the first clamping arm unit; a second clamping unit is disposed at the first end of the second clamping arm unit and is detachably connected to the first clamping unit, used to cooperate with the first clamping unit to clamp and stretch the cow mucus to detect the viscosity of the mucus; a measuring unit is rotatably disposed on the side of the first end of the first clamping arm unit or the side of the first end of the second clamping arm unit, used to measure the length of the cow mucus clamped by the first clamping unit and the second gripping unit.

[0003] The aforementioned technology has an X-shaped overall structure and lacks limiting components, requiring manual control when testing the number of times the mucus can be stretched without breaking. This results in excessively high operational requirements and the mucus may be accidentally broken due to excessive opening between the first and second gripping elements, leading to inaccurate detection. Therefore, to address the high operational difficulty of the aforementioned technology, we propose a replacement dairy cow breeding testing device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for measuring the selection of replacement dairy cows.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for selecting and measuring replacement dairy cows includes a pair of support rods. One end of each support rod is rotatably connected by a pin. Each support rod near the pin has a slot and a corresponding limiting plate is slidably inserted therein. The limiting plate has an adjustment groove in the middle of its body. Locking bolts and locking plates are respectively provided on the upper and lower sides of the limiting plate. The rod of the locking bolt passes through the adjustment groove and is connected to the locking plate. The other end of each support rod has a contact head through a quick-release assembly. An installation cylinder is installed at the end of each support rod near the contact head. A top spring is installed inside both installation cylinders.

[0007] Preferably, the quick-release assembly includes a plug rod and a rectangular insertion hole. The plug rod is fixed to the end face of the support rod, and the insertion hole is located inside the contact head. The contact head is inserted into the rod body of the plug rod through the insertion hole.

[0008] Preferably, a magnetic block is installed at one end of the plug rod inside the socket, and a matching adsorption sheet is installed on the end face inside the socket corresponding to the magnetic block.

[0009] Preferably, the limiting plate has scale markings on its body, and the scale markings are located on both sides of the adjustment groove.

[0010] Preferably, the locking plate has limiting protrusions at both ends, which extend to the side of the limiting plate.

[0011] Preferably, the mounting cylinder is a transparent cylinder with a smooth inner wall.

[0012] Preferably, the support rod has a grip groove in the middle of its body, and the groove wall has anti-slip texture.

[0013] The present invention provides a device for determining the selection and breeding of replacement dairy cows, which has the following advantages:

[0014] 1. In this utility model, a top spring is installed between the support rods via a mounting cylinder. When the operator does not actively grip the rods, the top spring pushes the rods apart, causing the contact head to open. This allows for the determination of the stretching length and number of stretches of the cow mucus. In summary, the pin and top spring design allows for one-handed operation, requiring only a squeeze. The top spring automatically opens the contact head, simplifying the operation. Furthermore, the combination of the limiting plate and locking bolt restricts the opening angle of the support rods, ensuring that the maximum distance of the contact head after each opening is a fixed value adjustable by the operator. This eliminates concerns about accidental breakage of the mucus due to insufficient operator skill. Thus, the cooperation of these components effectively simplifies the operation, reduces operational difficulty, and facilitates frequent cow breeding and testing.

[0015] 2. The quick-release component in this invention allows personnel to easily disassemble the contact head, enabling them to conveniently replace the used contact head after inspecting one or two cows, thus maintaining its cleanliness. The magnetic block and adsorption plate provide a certain degree of connection stability to the contact head, preventing it from detaching from the plug rod. The scale markings facilitate accurate judgment of the support rod's opening angle, aiding in determining the stretching length when stretching the vulvar mucus of the cow. The limiting protrusion ensures stable contact between the locking plate and the limiting plate, facilitating the installation of the locking bolt and preventing it from spinning freely.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figure 1-4A device for selecting and measuring replacement dairy cows includes a pair of support rods 1. One end of each support rod 1 is rotatably connected by a pin 2. Each support rod 1 has a slot near the pin 2 and a corresponding limiting plate 3 is slidably inserted therein. The limiting plate 3 has an adjustment groove in the middle of its body. The upper and lower sides of the limiting plate 3 are respectively provided with locking bolts 4 and locking plates 5. The rod of the locking bolt 4 passes through the adjustment groove and is connected to the locking plate 5. The other end of each support rod 1 has a contact head 6 provided by a quick-release assembly. The contact head 6 is used to contact the vulvar mucus of the dairy cow. Each support rod 1 has an installation cylinder 7 installed near the contact head 6. A top spring 8 is installed inside both installation cylinders 7.

[0024] Example 2

[0025] Reference Figure 1-4 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0026] The quick-release assembly includes a plug rod 9 and a rectangular insertion hole. The plug rod 9 is fixed to the end face of the support rod 1, and the insertion hole is located inside the contact head 6. The contact head 6 is inserted into the rod body of the plug rod 9 through the insertion hole. A magnetic block 10 is installed at one end of the plug rod 9 inside the insertion hole, and a matching adsorption piece 11 is installed on the end face inside the insertion hole corresponding to the magnetic block 10. The quick-release assembly allows personnel to easily disassemble the contact head 6, thus enabling personnel to quickly and conveniently disassemble the contact head after inspecting one or two cows. The contact head 6 is replaced after use to keep it clean. The magnetic block 10 and the adsorption plate 11 provide a certain degree of connection stability for the contact head 6 to prevent it from falling off the rod of the plug rod 9. The limiting plate 3 has scale marks on its plate body, which are located on both sides of the adjustment groove. The scale marks make it easy for personnel to accurately judge the opening angle of the support rod 1, thus facilitating the determination of the stretching length when stretching the vulvar mucus of dairy cows.

[0027] The locking plate 5 has limiting protrusions at both ends, which extend to the side of the limiting plate 3. The setting of the limiting protrusions allows the locking plate 5 to maintain a relatively stable contact with the limiting plate 3, thereby facilitating the installation of the locking bolt 4 and preventing it from spinning freely. The cylinder body of the mounting cylinder 7 is a transparent cylinder with a smooth inner wall. The transparent mounting cylinder 7 makes it easy for personnel to judge the condition of the top spring 8 inside, so as to replace or maintain the top spring 8 in a timely manner. The support rod 1 has a grip groove 12 in the middle of its body. The groove wall of the grip groove 12 has anti-slip texture, which makes it easy for personnel to grip.

[0028] Operating principle and advantages: In the process of using this utility model, since the lengths of the support rod 1 and the contact head 6 are both known fixed lengths, when the support rod 1 opens, the two support rods 1 and the pin 2 form an isosceles triangular frame, and the base of the triangle is the stretching length of the vulvar mucus of the cow. Thus, the stretching length of the vulvar mucus of the cow can be quickly determined. At the same time, in the above process, since the support rods 1 are provided with a limiting plate 3, and the limiting plate 3 is provided with an adjustment groove, a locking bolt 4, and a locking plate 5, that is, the locking bolt 4 provides the locking plate 5 to be fixed on the limiting plate 3. Thus, the locking bolt 5 can be installed in different positions through the adjustment groove, and the support rod 1 can only slide and open along the end of the limiting plate 3 and the locking bolt 4. That is, by adjusting the position of the locking bolt 4, the opening angle of the support rod 1 can be limited.

[0029] Furthermore, in the above process, since the support rods 1 are connected by a top spring 8 via the mounting sleeve 7, when the person does not actively grasp them, the top spring 8 pushes the support rods 1 away from each other, thereby causing the support rods 1 to open the contact head 6. This allows for the determination of the stretching length and number of stretches of the cow mucus. In summary, when the person grips the support rod 1 tightly, the support rod 1 causes the contact head 6 to move closer together, thus clamping the cow mucus. When the person releases the support rod 1, the top spring 8 pushes the support rod 1 away, causing the support rod 1 to move the contact head 6 away from each other. At this time, the mucus is... The extension of the contact head 6, combined with the cooperation of the limiting plate 3 and the locking bolt 4, restricts the opening angle of the support rod 1. Under the restriction of the locking bolt 4, the straight distance of the end of the contact head 6 after the support rod 1 is extended is only slightly greater than the specified extension length. For example, if it is determined that the cow mucus is qualified when it is stretched to 5 cm without breaking, the straight distance of the end of the contact head 6 after the support rod 1 is extended can be adjusted by the locking bolt 4 to be about 5.5 cm. Furthermore, the setting of the pin 2 allows the operator to hold it with one hand, thereby further improving the ease of operation.

[0030] Furthermore, the quick-release assembly allows for easy disassembly of the contact head 6, enabling personnel to conveniently replace it after inspecting one or two cows, thus maintaining its cleanliness. The magnetic block 10 and the suction plate 11 provide a degree of connection stability to the contact head 6, preventing it from detaching from the rod of the connector 9. The graduated markings facilitate accurate judgment of the opening angle of the support rod 1, aiding in determining the stretching length when stretching the vulva mucus of the cow. The limiting protrusion ensures stable contact between the locking plate 5 and the limiting plate 3, facilitating the installation of the locking bolt 4 and preventing it from spinning freely. The transparent mounting cylinder 7 allows personnel to assess the condition of the internal top spring 8, enabling timely replacement or maintenance. The grip groove 12 provides a comfortable grip for personnel.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
