Description

Technical Field

[0001] This utility model relates to the technical field of grain storage equipment, specifically a phosphine grain pile dosing device. Background Technology

[0002] Aluminum phosphide is a widely used fumigant in my country. Application methods commonly include fumigation through grain surface deliquescence, generators, small cloth bags, and buried probes. Small cloth bag fumigation is a highly efficient method, creating a high concentration of pesticide locally within the grain pile, resulting in good localized insecticidal effects. It offers high precision, requires less pesticide, and is economical. Furthermore, because the pesticide is contained within the cloth bag, it does not directly contact the grain, preventing contamination.

[0003] In current practices, when applying pesticides using small cloth bags, workers often use wooden sticks or iron rods to directly insert the bags into the grain pile. However, due to the high resistance of the grain pile, the bags are not buried deeply enough, affecting the fumigation effect. Furthermore, this method is slow and requires a significant amount of physical effort. The bags are also prone to tearing during the process, leading to pesticide leakage and contamination of the grain.

[0004] Therefore, a device that can easily and quickly deliver phosphine packets to a designated location within a grain pile, while avoiding damage to the packets during delivery, is urgently needed for development. Utility Model Content

[0005] The present invention aims to provide a phosphine grain pile dosing device. By setting a dosing cylinder with an inclined surface, the resistance when the dosing cylinder is inserted into the grain pile is reduced. At the same time, a flip-top is set to protect the phosphine package inside the dosing cylinder and prevent it from being damaged during dosing.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0007] A phosphine grain pile dosing device includes a dosing cylinder, a connecting rod, and a handle. The dosing cylinder and the handle are respectively located at both ends of the connecting rod. The dosing cylinder has an opening at its end, which is sloped and has a flip-top.

[0008] The dosing cylinder is equipped with a push plate and a push rod inside. One end of the push rod is connected to the push plate, and the other end passes through the connecting rod and extends out from the handle. The end of the push rod is equipped with a push handle.

[0009] As an improvement, the inclination angle of the bevel of the opening is 30-60°.

[0010] As an improvement, the bevel of the opening includes a long end and a short end, one end of the flap is hinged to the long end, and the other end is a free end pressed onto the short end.

[0011] As an improvement, the free end of the flip cover is provided with a magnetic suction part, which is used to attach the cover to the dosing cylinder.

[0012] As an improvement, the thickness of the magnetic attraction part is 0.3-0.6 cm.

[0013] As an improvement, the flip cover has a protrusion on the outside of the dosing cylinder.

[0014] As an improvement, the push plate is a rubber sheet.

[0015] As an improvement, a spring is fitted onto the push rod, and the two ends of the spring are respectively connected to the handle and the push handle.

[0016] The advantages of this utility model are:

[0017] The dosing cylinder of this invention features a slanted opening design with an inclination angle of 30° to 60°, which effectively reduces resistance when inserting into the grain pile, allowing the device to be inserted deeper into the grain pile more easily. The flip-top is magnetically attached to the cylinder body, preventing grain from entering the dosing cylinder and compressing the medicine bag during the dosing process, thus preventing the medicine bag from breaking during dosing and avoiding medicine leakage that could contaminate the grain.

[0018] This utility model features a reasonable overall structural design, facilitating operation and use. Operators do not need to expend excessive physical effort when administering medication, significantly improving work efficiency. This utility model not only improves medication administration efficiency and safety but also effectively reduces labor intensity, demonstrating high practicality and economic efficiency.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Example 1

[0030] This embodiment discloses a phosphine grain pile dosing device, such as... Figure 1 and Figure 2 As shown, it includes a dosing cylinder 1, a connecting rod 2 and a handle 3. The dosing cylinder 1 and the handle 3 are respectively located at both ends of the connecting rod 2. The dosing cylinder 1 has an opening 4 at its end. The opening 4 is set with an inclined surface and has a flip cover 5 on it.

[0031] like Figure 3 and Figure 4 As shown, the inclined angle of the slope of opening 4 is 30°. The inclined surface of opening 4 includes a long end 4a and a short end 4b. One end of the flip cover 5 is hinged to the long end 4a, and the other end is a free end pressed onto the short end 4b. A magnetic suction part 6 is provided on the free end of the flip cover 5, and it is attracted to the dosing cylinder 1 through the magnetic suction part 6. The thickness of the magnetic suction part 6 is 0.6cm.

[0032] like Figure 5 As shown, the dosing cylinder 1 has a push plate 7 and a push rod 8 inside. One end of the push rod 8 is connected to the push plate 7, and the other end passes through the connecting rod 2 and extends out from the handle 3. The end of the push rod 8 has a push handle 9. The push plate 7 is a rubber sheet. A spring 10 is sleeved on the push rod 8, and the two ends of the spring 10 are connected to the handle 3 and the push handle 9, respectively.

[0033] In this embodiment, the dosing cylinder 1 is a circular 304 stainless steel pipe with an outer diameter of 50mm and a wall thickness of 1.5mm. The length of the dosing cylinder 1 is 20cm.

The push rod 8 is a circular 304 stainless steel pipe with an outer diameter of 18mm and a wall thickness of 2mm, and is approximately 150cm long.

[0034] The following are the instructions for using the pesticide dispenser:

[0035] (a) The small cloth bag for phosphine drug should be long and thin, slightly smaller than the diameter of the dosing tube 1, and a hemp thread should be threaded through the mouth of the bag to facilitate drug dispensing.

[0036] (ii) Before applying the medicine, calculate the amount of medicine to be used, the number of burial points, and the number of small cloth bags, and mark the grain surface in advance.

[0037] (iii) When administering medication, a designated person should dispense the medication and pack it into bags in measured quantities.

[0038] (iv) The operation team consists of two people, one holding the medicine dispenser and the other holding the medicine bag.

[0039] (v) First, place the medicine bag inside the medicine dispensing cylinder 1 and close the flap 5. The magnetic suction part 6 can automatically adhere to the outer wall of the medicine dispensing cylinder 1. Insert the medicine dispensing cylinder 1 into the grain until the predetermined depth is reached, then lift the handle upwards. Because the magnetic suction part 6 has a certain thickness, it will be subjected to friction during the lifting process, causing the flap 5 to open automatically. At the same time, manually press the push handle 9, and the medicine bag will fall into the designated position in the grain pile under the push plate 7, completing the medicine dispensing.
