Description

Technical Field

[0001] This utility model relates to the field of wire probe adjustment technology, and in particular to a wire probe adjuster. Background Technology

[0002] A pig farm is a specialized facility for raising, breeding, fattening, and slaughtering pigs, with the aim of providing them for market sale. Staff at the farm need to design different feeding programs based on the number and size of pigs in each breeding area. These different feeding programs require adjusting the liquid level of the feed in the feeding troughs to suit varying breeding conditions.

[0003] In existing technologies, level gauges are generally used to monitor the feed level in the feeding trough to prevent overfeeding or underfeeding. However, different feeding programs involve different feed amounts, so the level gauge needs to adjust the probe (usually a steel wire) length according to the feeding program to adapt to the different feed level heights. The conventional adjustment method is to disassemble the steel wire probe fixing structure and replace it with a probe of a different length, or to reinstall the probe at a different position (length or height). However, regardless of the adjustment method, the steel wire probe needs to be disassembled and reinstalled, which is a cumbersome and inefficient process. Utility Model Content

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] A pig farm is a specialized facility for raising, breeding, fattening, and slaughtering pigs, with the aim of providing them for market sale. Staff at the farm need to design different feeding programs based on the number and size of pigs in each breeding area. These different feeding programs require adjusting the liquid level of the feed in the feeding troughs to suit varying breeding conditions.

[0029] like Figures 1-5 As shown, this utility model proposes a wire probe adjuster, which is installed on pipe 9.

[0030] The wire probe adjuster includes: a probe box 1, inside which a connector 2 is installed. The probe box 1 has a volumetric cavity with a second mounting hole 102 on one side and a guide hole 103 on the other side. The second mounting hole 102 and the guide hole 103 are coaxially aligned and communicate with the volumetric cavity. The probe box 1 also has a first mounting hole 101. A clamp 8 is installed on the outer surface of the pipe 9, passing through the first mounting hole 101 to fix the probe box 1 to the pipe 9. The clamp 8 allows for quick and easy fixing of the probe box 1 to the outside of the pipe 9.

[0031] like Figure 3 , Figure 6 As shown, the probe box 1 is connected to the limiter 4. The limiter 4 includes a housing 401, which is snapped into the second mounting hole 102 and is threaded with a fixing nut 3. In use, the housing 401 is fixed to the probe box 1 by the fixing nut 3.

[0032] The outer casing 401 has an internal groove with a gradually decreasing inner diameter. A guide tube 404 is slidably connected to the outer casing 401, and several steel balls 403 are disposed within the guide tube 404. The guide tube 404 is a variable-diameter tube with a gradually increasing outer diameter. Several circular holes are formed at the larger outer diameter end of the guide tube 404, and the steel balls 403 are positioned at these holes, forming a gap between them to allow the steel wire 7 (which serves as a probe structure connecting to an external level gauge) to pass through. The steel balls 403 are slidably connected to the outer casing 401.

[0033] A spring 402 is provided inside the outer casing 401. One end of the spring 402 is fixed to the outer casing 401, and the other end is fixed to the guide tube 404.

[0034] In this embodiment, as Figure 3 As shown, the steel wire 7 passes through the guide hole 103 and the guide tube 404, extends from the pipe 9 into the limiter 4, and extends out of the limiter 4. After the steel wire 7 extends into the pipe 9, the guide tube 404 is moved closer to the spring 402. At this time, the spring 402 contracts, the gap between the steel ball 403 and the outer shell 401 increases, the pressure of the outer shell 401 on the steel ball 403 disappears, and the gap between the steel balls 403 increases, allowing the steel wire 7 to pass freely through the gap. When it is necessary to adjust the extension of the steel wire 7 extending from the limiter 4, the steel wire 7 moves towards the pipe 9. At this time, there is friction between the outer shell 401 and the steel ball 403. The friction drives the steel ball 403 and the guide tube 404 to move towards the pipe 9. The spring 402 extends, and the inside of the outer shell 401 gradually tightens, causing the steel balls 403 to move radially and clamp the steel wire 7, thereby restricting the further movement of the steel wire 7. The greater the tension, the greater the resistance, thus completing the length adjustment of the steel wire 7.

[0035] like Figures 1-4 As shown, the probe box 1 is connected to the button 6, and the bottom end of the button 6 extends into the volume cavity of the probe box 1. The bottom end of the button 6 has an inwardly tapered portion 61, the thickness of which gradually decreases, and its surface is arc-shaped. The button 6 has a hole through which the steel wire 7 passes, the inner diameter of which is larger than the diameter of the steel wire 7. Pressing the button 6 moves the inwardly tapered portion 61 downwards, pushing the guide tube 404 gradually towards the side closer to the spring 402. This increases the gap between the steel ball 403 and the outer shell 401, facilitating the movement of the steel wire 7 among the steel balls 403.

[0036] It is understandable that button 6 is fixed to probe box 1 by pin 5. When moving or pressing button 6, pin 5 needs to be removed before pressing button 6.

[0037] After adjusting the length of the steel wire 7 extending from the limiter 4, feed is added to the feeding trough of the farm. The feed in the feeding trough gradually increases until the steel wire 7 contacts the top feed. The steel wire 7 then sends a signal to the level gauge, and the feeder stops feeding. The amount of feed that has been added is the preset amount of feed.

[0038] During the process of adjusting the extension length of the steel wire 7, it is only necessary to adjust the gap size between several steel balls 403 by sliding the guide tube 404 and the outer shell 401, so that the steel wire 7 passing through the gap can be moved and fixed. This process does not require disassembling the steel wire 7, and the length of the steel wire 7 extending out of the limiter 4 can be adjusted. The operation is simple, quick and efficient, and it is suitable for adjusting the liquid level in different feeding programs.

[0039] It should be noted that the pipe 9 in the attached drawings of this application is usually a horizontally placed round pipe in actual use. Therefore, the steel wire 7 usually extends downward and is located above the feeding trough in the farm.

[0040] Working principle: The steel wire 7 passes through the guide hole 103 and the guide tube 404, extends into the limiter 4 from the pipe 9, and extends out of the limiter 4. After the steel wire 7 extends into the pipe 9, pressing the button 6 causes the inner retractor 61 to move downward. The inner retractor 61 pushes the guide tube 404 to gradually move closer to the spring 402. At this time, the spring 402 contracts, the gap between the steel ball 403 and the outer shell 401 increases, the pressure of the outer shell 401 on the steel ball 403 disappears, and the gap between the steel balls 403 increases, allowing the steel wire 7 to pass freely through the gap. When it is necessary to adjust the extension of the steel wire 7, the steel wire 7 moves towards the pipe 9. At this time, there is friction between the outer shell 401 and the steel ball 403. The friction drives the steel ball 403 and the guide tube 404 to move towards the pipe 9. The spring 402 extends, and the inside of the outer shell 401 gradually tightens, causing the steel balls 403 to move radially and clamp the steel wire 7, thereby restricting the further movement of the steel wire 7.

[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
