Description

Technical Field

[0001] This utility model relates to the field of moisture detection technology, and in particular to a handheld feed moisture detection device. Background Technology

[0002] In existing technologies, feed moisture detection is a crucial step in ensuring feed quality, safe storage, and reasonable pricing. Standard testing methods include: oven drying method (national standard method) and rapid halogen moisture meter method; modern rapid testing technologies include: near-infrared spectroscopy (NIRS) and electrical resistance method.

[0003] A search revealed a Chinese patent application with patent number 202421802837.3, which discloses a feed moisture detection device. When adjustment is needed, the height of the detection component can be quickly adjusted by observing the level while rotating the corresponding adjustment cylinder relative to the connector, thus adapting to uneven surfaces and improving work efficiency.

[0004] The aforementioned patent has the following shortcomings: the device is large in size and inconvenient to carry; existing handheld feed moisture detection devices are based on the resistance method, such as the HF-LM8198 (single rod) moisture meter, in which the probe structure used to detect feed moisture is much longer than the main structure, and the front end of the probe is a sharp point. The conventional method is to put a protective shell on the front end of the probe, but the protection of the probe is not comprehensive enough, and the probe tip is easy to damage external objects, which is not conducive to the overall device being carried and used. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a handheld feed moisture detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A handheld feed moisture detection device, comprising: The moisture meter body has a detection probe fixedly installed at its top. A connecting positioning frame is fitted onto the bottom of the outer wall of the detection probe, and a limiting slide cylinder is fixedly connected to both sides of the connecting positioning frame. A guide slide rod is slidably installed inside the limiting slide cylinder. A protective cross arm is fixedly connected to the top of the guide slide rod, and a protective sleeve is fixedly connected to the middle of the bottom end of the protective cross arm. The protective sleeve is fitted onto the outer wall of the detection probe. Two symmetrically arranged clamping arc arms have clamping arc pads fixedly connected to their inner walls. One end of each clamping arc arm is rotatably connected to a positioning mounting pin, and the other end is threaded with a fixing threaded rod. Both the positioning mounting pin and the fixing threaded rod are connected to the connecting positioning frame.

[0007] As a further improvement of this utility model: a connecting gasket is sleeved on the top of the outer wall of the guide slide rod, and a support spring is fixedly connected to the bottom end of the connecting gasket.

[0008] As a further embodiment of this utility model: a connecting washer 2 is provided at the bottom end of the first supporting spring, and a second supporting spring 2 is provided at the bottom end of the second connecting washer.

[0009] As a further embodiment of this utility model: a connecting washer three is fixedly connected to the bottom end of the second supporting spring, and the two connecting washer three are fixedly installed on the top of the connecting positioning frame.

[0010] As a further improvement of this utility model: an internally threaded cylinder is fixedly connected to the top of the outer wall of the limiting slide cylinder, and a locking bolt is installed on the internal thread of the internally threaded cylinder.

[0011] As a further improvement of this utility model: two mounting grooves are symmetrically opened at the top of the connecting positioning frame, and a mounting slider is slidably installed inside the mounting groove.

[0012] As a further embodiment of this utility model: the bottom end of the mounting slider is fixedly connected to a connecting base, the bottom end of the connecting base is fixedly connected to a moisture meter corner clip, and the moisture meter corner clip is fixedly clipped to the top of the side wall of the moisture meter body.

[0013] As a further embodiment of this utility model: the top end of the mounting slider is fixedly connected to a mounting threaded rod, and a fixing nut is threaded onto the outer wall of the mounting threaded rod.

[0014] Compared with the prior art, this utility model provides a handheld feed moisture detection device, which has the following beneficial effects: 1. This handheld feed moisture detection device automatically and completely houses the tip of the detection probe in the protective sleeve after the detection is completed by compressing and storing energy through support spring one and support spring two, thus preventing the tip from being damaged by accidental collision or drop. This design is especially suitable for scenarios with frequent movement or storage, extending the probe's lifespan; at the same time, it can reduce the impact of the detection probe on the external environment.

[0015] 2. This handheld feed moisture detection device uses locking bolts to fix the position of the guide slide rod, allowing for flexible adjustment of the probe tip's extension length beyond the protective sleeve. For example, when measuring small amounts of feed, the probe extension can be shortened to avoid bottom damage; in large batches of feed, the probe can be fully extended to penetrate deep into the feed.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0019] 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.

[0020] A handheld feed moisture detection device, such as Figures 1 to 5 As shown, it includes: a moisture meter body 1 with a detection probe 2 fixedly mounted on its top and a connecting positioning frame 3 sleeved on the bottom of the outer wall of the detection probe 2.

[0021] The connecting positioning frame 3 is configured as an inverted U-shape, with a through hole at its top for mounting the detection probe 2. The diameter of the through hole is larger than the diameter of the detection probe 2 to avoid damage to the probe surface. Two clamping arc arms 14 are symmetrically arranged at the top of the connecting positioning frame 3. Clamping arc pads 15 are bonded to the inner wall of the clamping arc arms 14. The clamping arc pads 15 are clamped to the outer wall of the detection probe 2 to fix the detection probe 2 and make the axis of the detection probe 2 coincide with the axis of the through hole.

[0022] One end of the clamping arc arm 14 is rotatably connected to a positioning mounting pin 16, which is welded to the top of the connecting positioning frame 3. The other end of the clamping arc arm 14 is threaded with a fixing threaded rod 17, the lower part of which is threaded to the connecting positioning frame 3. A limit pin 18 is engaged between the two clamping arc arms 14 at the end away from the positioning mounting pin 16. The limit pin 18 is welded to the top of the connecting positioning frame 3 to ensure the positioning effect of the detection probe 2.

[0023] Two mounting grooves 19 are symmetrically opened at the top of the connecting positioning frame 3. The two mounting grooves 19 are respectively located on both sides of the through hole, and the mounting slider 20 is slidably installed inside the mounting groove 19. The top of the mounting slider 20 is fixedly connected to the mounting threaded rod 21, and the outer wall of the mounting threaded rod 21 is threaded with a fixing nut 22.

[0024] A compression washer is provided at the bottom of the fixing nut 22 to compress the connecting positioning frame 3. The friction generated by the compression is used to fix the mounting slider 20 inside the mounting groove 19. The bottom of the mounting slider 20 is fixedly connected to the connecting base 23, and the bottom of the connecting base 23 is fixedly connected to the moisture meter corner clip 24. The moisture meter corner clip 24 is fixedly clipped to the top of the side wall of the moisture meter body 1.

[0025] Both sides of the connecting positioning frame 3 are fixedly connected to the limiting slide cylinder 4. The limiting slide cylinder 4 has a guide slide rod 5 slidably installed inside. The bottom end of the guide slide rod 5 extends downward out of the limiting slide cylinder 4 and is fixedly installed with the limiting sleeve block 27 by bolts.

[0026] The top ends of the two guide slide rods 5 are fixedly connected to protective cross arms 6, and the middle of the bottom end of the protective cross arms 6 is fixedly connected to a protective sleeve 7. The protective sleeve 7 is sleeved on the outer wall of the detection probe 2, and both sides of the outer wall of the protective sleeve 7 are welded with reinforcing ribs 8 that are fixedly connected to the protective cross arms 6. The inner cavity of the protective sleeve 7 passes through the protective cross arms 6, and the inner diameter of the protective sleeve 7 is larger than the diameter of the detection probe 2.

[0027] A connecting gasket 19 is fitted onto the top of the outer wall of the guide slide rod 5. A support spring 10 is fixedly connected to the bottom end of the connecting gasket 19. A connecting gasket 21 is provided at the bottom end of the support spring 10. A support spring 22 is provided at the bottom end of the connecting gasket 21. A connecting gasket 313 is fixedly connected to the bottom end of the support spring 212. The two connecting gaskets 313 are fixedly installed on the top of the connecting positioning frame 3.

[0028] The elastic force generated by the compression of two support springs 10 and 12 ensures that the tip of the detection probe 2 is quickly covered by the protective sleeve 7 after the feed moisture detection is completed, preventing adverse effects on the tip. Figure 1As shown, at this time, the support spring 10 and the support spring 2 are in a slightly compressed state, the tip of the detection probe 2 is completely inside the protective sleeve 7, and the limiting sleeve 27 is attached to the bottom end of the limiting slide 4, which is also the initial state of the whole device.

[0029] The top of the outer wall of the limiting slide cylinder 4 is fixedly connected to an internally threaded cylinder 25. The internal threads of the internally threaded cylinder 25 are fitted with locking bolts 26. When the locking bolts 26 are rotated clockwise, they press against the guide slide rod 5, keeping the guide slide rod 5 and the connecting positioning frame 3 in a relatively fixed state. This ensures the protective sleeve 7 can protect the tip of the detection probe 2, and also allows for adjustment of the depth to which the tip of the detection probe 2 is inserted into the feed according to actual usage needs.

[0030] Working principle: Please refer to Figures 1 to 5 Assemble the device as shown in the figure; this device has the following two methods for measuring the moisture content of feed piles: Method 1 (applicable to large quantities of feed): Loosen the locking bolt 26, then hold the moisture meter body 1 and insert the tip of the detection probe 2 into the feed. The contact area between the feed and the protective cross arm 6 is large, which will prevent the protective cross arm 6 from entering the feed. Then, the moisture of the feed is detected by the detection probe 2 and the moisture reading is taken by the moisture meter body 1. Method 2 (applicable to small amounts of feed): Determine the length of the tip of the detection probe 2 extending beyond the protective sleeve 7 based on the amount of feed (e.g., the height of the feed inside the storage tank), then tighten the locking bolt 26 to keep the protective sleeve 7 at its current extension length, and then measure the moisture content of the feed; avoid the tip of the detection probe 2 touching the bottom, which could cause damage.

[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.
