[0037] In this embodiment, as Figure 1 and Figure 2 As shown, a punch plate type bulk solid flow meter includes a flow meter body 1, a detection plate 11 disposed in the flow meter body 1, and a feeding assembly 2 installed on the flow meter body 1. The feeding assembly 2 is used to guide the solid sample to the inclined surface of the detection plate 11. The feeding assembly 2 includes a feeding pipe 21, a guide shell 22, and an adjusting component 23. The bottom end of the feeding pipe 21 extends into the inner cavity of the flow meter body 1. The guide shell 22 is inserted into the bottom end of the feeding pipe 21. The adjusting component 23 is used to adjust the position of the guide shell 22 to guide the solid sample to the inclined surface of the detection plate 11.

[0038] Therefore, when measuring lighter materials, the adjustment component 23 is activated to drive the guide shell 22 to move downward along the outer wall of the feed pipe 21, thereby shortening the distance between the discharge position of the feed pipe 21 and the detection plate 11. The material is discharged at an angle along the discharge port at the bottom of the guide shell 22 to impact the detection plate 11, so that the material can fully contact the detection plate 11 when it falls.

[0039] Specifically, the flow meter body 1 is a punch plate type bulk solid flow meter, the detection plate 11 is a component of the flow meter body 1, the detection plate 11 is used to detect the horizontal component of the impact force generated when the material impacts the tilted detection plate 11, the feed pipe 21 is processed into a square tube shape, the inner cavity of the guide shell 22 is adapted to the feed pipe 21, and the outlet of the guide shell 22 is correspondingly set to the detection plate 11.

[0040] In some embodiments, such as Figure 2 As shown, the adjusting component 23 includes a threaded sleeve 231, a screw 232, and an ear plate 233.

[0041] Specifically, the threaded sleeve 231 is located at the top of the flow meter body 1, and the screw 232 is used to push the ear plate 233 to move, so as to drive the guide shell 22 to move up and down on the outer wall of the feed pipe 21. The distance between the guide shell 22 and the detection plate 11 is adjusted according to the degree of crushing of the solid test material.

[0042] In some embodiments, such as Figure 3 As shown, a material control component 24 is configured on the feed pipe 21. The material control component 24 is used to control the feeding speed of the solid test object into the flow meter body 1. The material control component 24 includes a mounting shell 241, a rotating shaft 242, a flap 243 and a motor 244. The bottom end of the mounting shell 241 is connected to the feed pipe 21. The rotating shaft 242 is connected to the mounting shell 241 through a bearing. The flap 243 is inserted into the outer periphery of the rotating shaft 242 and is located in the cavity of the mounting shell 241.

[0043] Specifically, a rectangular cavity is machined in the mounting shell 241. The solid test material in the mounting shell 241 is introduced into the feed pipe 21. The rotating shaft 242 is located in the middle of the mounting shell 241. The flap 243 is used to stir the solid test material, control the feeding speed, and reduce the agglomeration of the solid test material. The motor 244 is connected to the rotating shaft 242 through a coupling.

[0044] In some embodiments, such as Figure 5As shown, an opening and closing assembly 3 is installed at the bottom of the flow meter body 1. The opening and closing assembly 3 is used to clean the material remaining in the flow meter body 1. The opening and closing assembly 3 includes a material collection shell 31, a locking member 32, and a discharge pipe 33. The material collection shell 31 is located at the bottom of the flow meter body 1. The material collection shell 31 is connected to the flow meter body 1 through the locking member 32. The top end of the discharge pipe 33 is connected to the material collection shell 31.

[0045] Specifically, the collecting shell 31 has a cavity that is wider at the top and narrower at the bottom, and the discharge pipe 33 is located at the bottom of the collecting shell 31. The discharge pipe 33 is used to discharge the solid test material in the collecting shell 31.

[0046] In some embodiments, such as Figure 4 As shown, the bottom end of the discharge pipe 33 is connected to a flexible hose 34, and the bottom end of the flexible hose 34 is fixedly connected to a flange 35.

[0047] Specifically, the hose 34 is made of rubber material, and the flange 35 is designed for connection with external pipelines, with multiple through holes distributed in the flange 35.

[0048] In some embodiments, such as Figure 1 and Figure 5 As shown, the locking member 32 includes a pin 321, a bolt 322, and a reset member 323. The top end of the pin 321 is fixedly connected to the flow meter body 1, and the bottom end of the pin 321 extends into the limiting hole of the collection shell 31. The pin 321 is connected to the collection shell 31 by the bolt 322. The reset member 323 is located in the limiting hole of the collection shell 31. The reset member 323 is used to drive the pin 321 to move upward so that the flow meter body 1 and the collection shell 31 are separated.

[0049] There are four pins 321. The pins 321 are machined with threaded holes that are compatible with bolts 322. The pins 321 are inserted into the limiting holes of the collecting shell 31 and connected to the bolts 322 to fix the collecting shell 31 and the flow meter body 1.

[0050] In some embodiments, such as Figure 5 As shown, the reset member 323 includes an elastic member 323a and a pad 323b. The elastic member 323a is located in the limiting hole of the collection shell 31. The bottom end of the pad 323b is fixedly connected to the elastic member 323a, and the top end of the pad 323b abuts against the pin 321.

[0051] Specifically, four limiting holes adapted to the elastic element 323a are machined in the material collection shell 31, the pad 323b is machined in a stepped shape, and the elastic element 323a is located between the pad 323b and the material collection shell 31.

[0052] In some embodiments, such as Figure 5 As shown, the elastic element 323a is a compression spring.

[0053] Specifically, the elastic element 323a adopts a compression spring design, which facilitates pushing the pad 323b upward to push the pin 321 out of the limiting hole of the collection shell 31.

[0054] In some embodiments, such as Figure 3 As shown, a transparent plate 241a is fixedly connected in the mounting shell 241. The transparent plate 241a is used to observe the material feeding situation in the mounting shell 241.

[0055] The transparent plate 241a is located on the side wall of the mounting shell 241. Two transparent plates 241a are provided to facilitate observation of the material feeding process in the mounting shell 241. The transparent plate 241a is made of transparent plastic material.

[0056] In some embodiments, such as Figure 2 As shown, the bottom of the feed guide shell 22 is inclined to feed material onto the inclined surface of the detection plate 11.

[0057] The discharge port of the feed guide shell 22 is parallel to the inclined surface of the detection plate 11, so that the solid test object can impact the inclined surface of the detection plate 11.

[0058] The working principle of this application is illustrated below with a preferred embodiment:

[0059] Depending on the degree of pulverization of the solid test material, the screw 232 is rotated in the threaded sleeve 231. The screw 232 drives the ear plate 233 to move, which in turn drives the guide shell 22 to move downward along the outer wall of the feed pipe 21. This shortens the distance between the discharge position of the feed pipe 21 and the detection plate 11, ensuring that the material contacts the detection plate 11 upon falling. The motor 244 is then started, driving the rotating shaft 242 to rotate within the mounting shell 241. The flap 243 rotates along with the rotating shaft 242, thus feeding the solid test material into the mounting shell 241. In step 1, the rotating flap 243 agitates the solid test object, controls the feeding speed of the solid test object, and the solid test object slides down the inclined surface of the detection plate 11, collects in the collection shell 31 and is discharged through the discharge pipe 33. However, when the flow meter body 1 needs to be disassembled, the rotating bolt 322 and the pin 321 are separated. Under the action of the elastic element 323a, the pad 323b is pushed upward, and then the pad 323b pushes the pin 321 out of the collection shell 31. The bent hose 34 cleans the solid test object remaining in the collection shell 31.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
