When the second electric telescopic rod is started, the gate can be controlled to control the size of the opening formed in the rectangular discharge trough, thereby controlling the discharge speed of the rectangular discharge trough. The bottom of the rectangular discharge trough corresponds to the width direction of the conveyor belt, so that the rice falling from the rectangular discharge is evenly laid on the conveyor belt. The flow rate control is directly related to the thickness of the rice laid on the conveyor belt, so that the rice is evenly laid on the conveyor belt, and further the rice on the left side of the valve plate will not accumulate too much. After the valve plate is flattened again, the rice on the conveyor belt is evenly laid and the laying thickness can be flexibly adjusted, which is convenient for the subsequent detection work of the metal detector and enhances practicality.

[0026] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0027] Reference Figure 1-6 A metal detection device for rice processing includes: a support frame 1, a conveyor belt 2 is installed inside the support frame 1, and a metal detector 5 is provided on the upper side of the support frame 1. It should be noted that the metal detector 5 is an instrument that detects metals using the principle of electromagnetic induction. Its working mechanism includes a transmitting coil generating an electromagnetic field, and a receiving coil capturing the magnetic field changes caused by metal objects, thereby performing detection. This is an existing conventional metal detection technology and will not be described in detail here; a mounting plate 13 is fixedly installed on the right side of the support frame 1, and a horizontal plate 14 is fixedly installed on the upper side of the mounting plate 13, and a flow regulating mechanism is provided on the horizontal plate 14; the flow regulating mechanism The structure includes a rice cone hopper 15, which is fixedly mounted on a horizontal plate 14. A rectangular feed trough 16 is fixedly connected to the lower side of the rice cone hopper 15. The rectangular feed trough 16 passes through to the bottom of the horizontal plate 14. A gate plate 17 is slidably mounted on the side of the horizontal plate 14. A connecting plate 18 is fixedly mounted on the outer end of the gate plate 17. A second electric telescopic rod 20 is arranged between the connecting plate 18 and the rectangular feed trough 16. A flexible guide plate 22 is connected between the inner end of the gate plate 17 and the upper edge of the rectangular feed trough 16. Side ear seats 19 are fixedly mounted on both sides of the rectangular feed trough 16. The second electric telescopic rod 20 is fixedly mounted between the connecting plate 18 and the side ear seat 19.

[0028] In this method, a guide arc plate 21 is screwed onto the rear side of the rectangular material trough 16. The guide arc plate 21 is bent to the bottom of the rectangular material trough 16. A gap is left between the guide arc plate 21 and the upper side of the conveyor belt 2, and a number of balls are installed at the bottom of the guide arc plate 21.

[0029] Through the above-mentioned arrangement, the guide arc plate 21 guides the material falling from the rectangular discharge chute 16, and guides the rice to be transported to the side conveyor belt 2. At the same time, a number of balls are arranged at the bottom of the guide arc plate 21. Since the height of the upper side of the conveyor belt 2 will change to a certain extent during daily use, and since the conveyor belt is made of flexible material, the arrangement of the balls reduces the friction between the guide arc plate 21 and the conveyor belt 2.

[0030] In this embodiment, a mounting bracket 3 is fixedly mounted on the right side of the conveyor belt 2 , a metal detector 5 is fixedly mounted on the mounting bracket 3 , and a controller 4 is fixedly mounted on the mounting bracket 3 .

[0031] In this method, support side plates 6 are fixedly installed on both sides of the middle position of the conveyor belt 2, a first electric telescopic rod 7 is fixedly installed on the support side plates 6, a movable top plate 8 is fixedly installed on the upper side of the first electric telescopic rod 7, a valve plate 9 is fixedly installed on the bottom of the movable top plate 8, the width of the valve plate 9 is adapted to the width of the conveyor belt 2, an installation groove 10 is opened at the bottom of the valve plate 9, and an infrared ranging probe 11 is fixedly installed inside the installation groove 10.

[0032] By the above arrangement, the infrared ranging probe 11 can detect the distance between the valve plate 9 and the upper side of the conveyor belt 2 when working, and the infrared ranging probe 11 can provide data of the distance between the bottom of the valve plate 9.

[0033] In this embodiment, an annular groove 12 is formed at the end of the mounting groove 10 , and a transparent protective glass is installed inside the annular groove 12 .

[0034] By the above arrangement, the transparent protective glass improves the installation effect of the infrared ranging probe 11 installed in the installation groove 10.

[0035] In this embodiment, the flexible guide plate 22 includes a flexible rubber plate 23 and a supporting corrugated plate 24 . The supporting corrugated plate 24 is fixedly connected to the inner side of the flexible rubber plate 23 .

[0036] Through the above-mentioned arrangement, the flexible guide plate 22 is a combined plate of the flexible rubber plate 23 and the supporting corrugated plate 24. The outer surface of the flexible rubber plate 23 is smooth and has a good material guiding effect. The supporting corrugated plate 24 supported on the inner side also has good deformation ability, while providing structural strength with the flexible rubber plate 23 as a whole, thereby improving practicality.

[0037] The working principle of the metal detection device for rice processing provided by the utility model is as follows:

[0038] When in use, the rice to be tested is added to the rice cone hopper 15, and the distance between the valve plate 9 and the conveyor belt 2 is first measured by the infrared ranging probe. The laying thickness of the rice is input into the controller 4, and the controller 4 drives the movable top plate 8 to move by controlling the first electric telescopic rod 7. When the distance between the valve plate 9 at the bottom of the movable top plate 8 and the conveyor belt 2 matches the controlled laying thickness of the rice, the first electric telescopic rod 7 stops driving and the conveyor belt 2 starts. Subsequently, the second electric telescopic rod 20 changes the rectangular feeding trough 1 by starting the gate plate 17 inside the control connecting plate 18. 6, the rice added to the rice cone hopper 15 slides down through the rectangular feeding trough 16, and then slides onto the conveyor belt 2 through the guide arc plate 21. The rice that slides onto the conveyor belt 2 is evenly laid again after passing through the bottom of the valve plate 9. The thickness of the rice that has passed through the valve plate 9 is smaller and more uniform. When the rice passes under the metal detector 5, if there are metal impurities in the rice, it will disturb the originally stable magnetic field when it is in the magnetic field area of the metal detector 5. This disturbance is captured and processed by the highly sensitive receiving coil, thereby triggering an alarm or automatic rejection device.

[0039] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
