Abstract
Description
Technical Field
[0001] The utility model belongs to the field of grain and oil detection, in particular to a grain and oil condition safety detection device. Background Art
[0002] Grain and oil safety testing is the process of evaluating the quality and safety of grains and edible oils. It aims to test their physical and chemical indicators, microbial content, heavy metals and harmful substances to ensure that the products meet national standards and protect consumer health.
[0003] Temperature is a crucial criterion when monitoring grain stored in silos. Excessively high silo temperatures can accelerate grain oxidation and even lead to hazards such as spontaneous combustion. Therefore, regular silo temperature monitoring is essential. A resistance temperature probe is an effective tool for this purpose. For silos with a certain depth, the probe can be inserted into the silo for testing.
[0004] However, the rod of the resistance temperature measuring rod is usually of standard length, such as Figure 1 As shown, the depth it can be inserted into a granary is fixed. However, in practice, there is no standard for the depth of granaries. Therefore, due to length limitations, it can only be used in granaries with a suitable depth. Its practicality needs improvement. Utility Model Content
[0005] Technical problem to be solved: How to make the length of the resistance temperature measuring rod adjustable.
[0006] Technical solution: The utility model provides a grain and oil status safety detection device, including a main structure and an improved structure: the main structure includes a temperature measuring head, a digital display screen is provided on the top of the temperature measuring head, and a resistance rod is provided on the top of the temperature measuring head, and the resistance rod is composed of multiple connecting rods of equal length; the improved structure includes a splicing mechanism, after the connecting rods are spliced into resistance rods through the splicing mechanism, the resistance rods are spliced with the temperature measuring head.
[0007] Furthermore, the splicing mechanism includes studs connected to the top end of each connecting rod. At the same time, the bottom ends of the temperature measuring head and other connecting rods except the lowest connecting rod are provided with screw holes adapted to the studs.
[0008] Furthermore, the bottom end of the lowest connecting rod is formed into a rounded structure, and the rounded structure is used to reduce friction with the contact object.
[0009] Furthermore, two handles are symmetrically mounted on the top of the temperature measuring head, and the cross-section of the handles is a planar structure.
[0010] Furthermore, a through hole is formed on the handle, through which a thin rod slightly longer than the resistance rod is movably passed, and a scraper which is movably passed through the resistance rod and has a diameter larger than the resistance rod is fixed at the bottom ends of the two thin rods.
[0011] Furthermore, a limit head with a diameter larger than that of the through hole is installed on the top end of the thin rod, and the limit head is detachable.
[0012] Furthermore, a locking hole is provided at the top end of the thin rod, and at the same time, a locking column that can be engaged with the locking hole is connected to the bottom end of the limiting head.
[0013] Furthermore, the engaging column is an elastic column, and its diameter is slightly larger than the diameter of the engaging hole.
[0014] Technical effects:
[0015] 1. In the utility model, the resistance rod is composed of a plurality of connecting rods of equal length, which are spliced into a complete resistance rod by a splicing mechanism and then assembled with the temperature measuring head. In this way, the length of the entire resistance rod can be adjusted according to the depth of the granary, making it more practical. At the same time, dividing the resistance rod into multiple connecting rods is also more convenient to carry.
[0016] 2. In the utility model, based on the existence of the handle, the thin rod and the scraper are equivalent to forming a cleaning mechanism. Since the thin rod is movable through the handle, when the resistance rod is inserted into the granary, the scraper and the thin rod will slide upward due to the reaction force of the grain, and will not affect the resistance rod. When the resistance rod is pulled out, under the action of gravity, the thin rod and the scraper gradually move downward, which is opposite to the moving direction of the resistance rod. In this way, the scraper can be used to scrape off the grain particles attached to the resistance rod to avoid taking out the grain and causing waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0024] The grain and oil safety detection device provided in this embodiment is as follows: Figure 2 and Figure 3 As shown, it includes a main structure and an improved structure, wherein:
[0025] The main structure includes a temperature measuring head 1, a digital display screen 2 is set at the top of the temperature measuring head 1 for displaying the measured temperature, and a resistance rod 3 is set at the top for inserting into the granary for temperature measurement. The resistance rod 3 is composed of multiple connecting rods 4 of equal length.
[0026] The improved structure includes a splicing mechanism 5, after the connecting rod 4 is spliced into the resistance rod 3 through the splicing mechanism 5, the resistance rod 3 is spliced with the temperature measuring head 1. Figure 2 As shown, the splicing mechanism 5 includes a stud 501 connected to the top of each connecting rod 4. At the same time, screw holes 502 that are compatible with the stud 501 are provided at the bottom end of the temperature measuring head 1 and the bottom ends of other connecting rods 4 except the lowest connecting rod 4. That is to say, through the action of the stud 501 and the screw hole 502, after the connecting rods 4 are assembled into a complete resistance rod 3, this resistance rod 3 can be assembled with the temperature measuring head 1.
[0027] Worth mentioning:
[0028] 1. The bottom end of the lowest connecting rod 4 is formed into a rounded structure, which is used to reduce the friction between the contact object and facilitate the insertion of the resistance rod 3 into the granary.
[0029] 2. Two handles 6 for holding are symmetrically installed on the top of the temperature measuring head 1. The cross section of the handle 6 is preferably a flat structure. Because the thin rod 8 below needs to pass through the handle 6, a flat structure is more conducive to drilling.
[0030] Based on the handle 6, as Figure 3As shown, a through-hole 7 is formed through the handle 6. A thin rod 8, slightly longer than the resistor rod 3, movably passes through the through-hole 7. A scraper 9, larger in diameter and movably extending through the resistor rod 3, is fixed to the bottom ends of the two thin rods 8. These thin rods 8 and scraper 9 form a cleaning mechanism. Because the thin rods 8 movably pass through the handle 6, when the resistor rod 3 is inserted into the granary, the scraper 9 and thin rod 8 are subjected to the reaction force of the grain and slide upward without affecting the resistor rod 3. However, when the resistor rod 3 is removed, gravity causes the thin rod 8 and scraper 9 to gradually move downward, in the opposite direction of the movement of the resistor rod 3. This allows the scraper 9 to scrape off any grain particles adhering to the resistor rod 3, preventing it from being carried out and wasted. Furthermore, to prevent the thin rods 8 from falling when in use while remaining removable when not in use, a removable stopper 10, larger in diameter than the through-hole 7, is mounted at the top of the thin rods 8. The reason for the detachable design is that the top of the thin rod 8 is provided with a locking hole 11, and the bottom of the stopper head 10 is connected to a locking post 12 that can engage with the locking hole 11. The locking post 12 is an elastic post with a diameter slightly larger than that of the locking hole 11, so that it can elastically engage with the locking hole 11 tightly.
