[0025] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Example 1

[0026] like Figure 1-4 As shown, the utility model proposes an adjustable valve metering machine, including a metering machine discharge channel 1, and also includes a connecting frame 2, the connecting frame 2 is fixedly connected to the bottom of the metering machine discharge channel 1; a receiving hopper 3, the receiving hopper 3 is fixedly connected to one end of the connecting frame 2 away from the metering machine discharge channel 1, and the top of the receiving hopper 3 is located directly below the bottom end of the metering machine discharge channel 1, the bottom end of the receiving hopper 3 is fixedly connected with a discharge pipe 4 for diversion, and a receiving basin 5 for receiving materials is arranged directly below the bottom end of the discharge pipe 4; a rotating valve shaft 10 is rotatably connected through the discharge pipe 4, and one end of the rotating valve shaft 10 located in the discharge pipe 4 is fixedly connected with a rotating valve block 11 adapted to the inner pipe wall of the discharge pipe 4; a mounting plate 6 is installed on the top of the receiving hopper 3, a stirring mechanism 8 for preventing material blockage is installed on the mounting plate 6, and a dredging mechanism 9 for accelerating the passage of materials is installed at the bottom of the stirring mechanism 8;

[0027] First, the material will smoothly slide down the discharge channel 1 of the metering machine into the receiving hopper 3, and enter the receiving basin 5 through the diversion and flow limiting of the receiving hopper 3 and the discharge pipe 4 to be collected. In this process, the rotating valve shaft 10 can be rotated to drive the rotating valve block 11 to rotate in the discharge pipe 4, so as to adjust the gap between the valve and the discharge pipe 4, and then control the outflow rate of the material. The stirring mechanism 8 and the unblocking mechanism 9 can timely alarm and unblock the blocked material when the material is blocked.

[0028] The stirring mechanism 8 includes a small motor 801, which is fixedly connected to the top of the mounting plate 6. The output shaft of the small motor 801 passes through the mounting plate 6 and is fixedly installed with a threaded rotating rod 804. A plurality of stirring rods 805 that are compatible with the inner diameter of the receiving hopper 3 are plugged and fixed on the threaded rotating rod 804. The stirring rod 805 is in the shape of a diamond. Through this arrangement, when a blockage problem occurs, the small motor 801 can be started, and the output shaft of the small motor 801 will drive the threaded rotating rod 804 to rotate. The accumulated materials can be stirred by plugging and fixing the plurality of stirring rods 805 on the threaded rotating rod 804, thereby accelerating the flow of materials and alleviating the blockage problem.

[0029] The stirring mechanism 8 also includes a monitor 802 and a warning light 803, both of which are installed on the top of the mounting plate 6. A color pigment ring is provided on the inner wall of the receiving hopper 3 near the top, and the monitor 802 is arranged opposite to the color pigment ring. Through this arrangement, the discharge of materials in the receiving hopper 3 can be conveniently monitored at any time. When the material is blocked, the accumulated material will cover the color pigment ring. When the monitor 802 cannot monitor the color pigment ring, it will send a signal to the external controller, and start the small motor 801 and the warning light 803 at the same time. The warning light 803 will flash, prompting personnel to come and check to avoid the problem from worsening and affecting production. At the same time, the output shaft of the small motor 801 will drive the threaded rotating rod 804 and the stirring rod 805 to stir the accumulated material, accelerate the flow of materials, and alleviate the blockage problem, thereby achieving intelligent monitoring of the material discharge and intelligent and rapid resolution of sudden blockage problems.

[0030] The dredging mechanism 9 includes a threaded sleeve 901, the top of which is sleeved on the bottom end of the threaded rotating rod 804 and is threadedly connected to the threaded rotating rod 804. Two symmetrical slide grooves 902 are provided on the outer wall of the threaded sleeve 901. The slide groove 902 is limited and slidably connected to a limit block 903. The end of the limit block 903 away from the slide groove 902 is fixedly connected to the inner wall of the hopper 3. The bottom end of the threaded sleeve 901 is fixedly connected to a connecting block 904. The bottom end of the connecting block 904 is fixedly connected to an impact block 9 05. Through the above arrangement, when the threaded rotating rod 804 rotates, the threaded connection relationship between the threaded rotating rod 804 and the threaded sleeve 901 and the limiting sliding connection relationship between the slide groove 902 and the limit block 903 can facilitate the vertical lifting movement of the threaded sleeve 901 at the bottom end of the threaded rotating rod 804. During the lifting process of the threaded sleeve 901, the connecting block 904 and the impact block 905 will be driven to impact and break the material blocked at the discharge pipe 4, thereby accelerating the passage of the material and solving the problem of material blockage.

[0031] The top of the impact block 905 is set to a truncated cone shape; the bottom of the impact block 905 is set to a conical shape. Through this setting, it is convenient to break the blocking material at the bottom and break the covering material at the top during the up and down lifting movement of the impact block 905, thereby improving the lifting efficiency and accelerating the breaking effect of the blocked material.

[0032] A plurality of grabbing mechanisms 7 are arranged on the outer wall of the impact block 905, and the grabbing mechanisms 7 include grooves 701. The plurality of grooves 701 are arranged in a ring array on the impact block 905, and the plurality of grooves 701 are rotatably connected with rotating blocks 702, and a folded plastic film 703 is fixedly connected between the rotating block 702 and the grooves 701. By arranging a plurality of grabbing mechanisms 7 on the outer wall of the impact block 905, when the threaded sleeve 901 drives the impact block 905 to descend, the impact block 905 will break the material through the conical end at the bottom, and at this time, the rotating block 702 is squeezed back into the groove 701 by the material. When the impact block 905 rises, the rotating block 702 and the folded plastic film 703 unfold under the rising potential energy and the friction of the material, and re-grab the nearby blocked material for re-stirring, which directly solves the problem of material blockage.

[0033] A spring wire 704 is arranged in the folded plastic film 703, and the two ends of the spring wire 704 are fixedly connected to the groove 701 and the rotating block 702 respectively. Through this arrangement, when the rotating block 702 moves downward and squeezes the material and retracts into the groove 701, the spring wire 704 is compressed and reset when the rotating block 702 rises, thereby assisting the rapid rebound of the rotating block 702, thereby facilitating the rotating block 702 and the folded plastic film 703 to re-grab the blocked material and solve the problem of material blockage.

[0034] Working principle: First, the material will smoothly slide down from the discharge channel 1 of the metering machine into the receiving hopper 3, and enter the receiving basin 5 through the diversion and flow limiting of the receiving hopper 3 and the discharge pipe 4 to be collected. In this process, the rotating valve shaft 10 can be rotated to drive the rotating valve block 11 to rotate in the discharge pipe 4, so as to adjust the gap between the valve and the discharge pipe 4, and then control the outflow rate of the material. The stirring mechanism 8 and the dredging mechanism 9 can timely alarm and dredge the blocked material when the material is blocked;

[0035] In the above process, when the material is blocked, the accumulated material will cover the color pigment ring. When the monitor 802 cannot monitor the color pigment ring, it will send a signal to the external controller, and start the small motor 801 and the warning light 803 at the same time. The warning light 803 will flash to prompt the personnel to come and check, so as to avoid the problem from getting worse and affecting the production. At the same time, the output shaft of the small motor 801 will drive the threaded rotating rod 804 and the stirring rod 805 to stir the accumulated material, accelerate the flow of materials, and alleviate the blockage problem. Finally, the material discharge situation is intelligently monitored, and the sudden blockage problem is intelligently and quickly solved.

[0036] When the threaded rotating rod 804 rotates, the threaded connection between the threaded rotating rod 804 and the threaded sleeve 901 and the limited sliding connection between the slide groove 902 and the limit block 903 facilitate the vertical lifting movement of the threaded sleeve 901 at the bottom end of the threaded rotating rod 804. During the lifting process of the threaded sleeve 901, the connection block 904 and the impact block 905 are driven to impact and break the material blocked at the discharge pipe 4, thereby accelerating the passage of the material and solving the problem of material blockage.

[0037] In addition, when the threaded sleeve 901 drives the impact block 905 to descend, the impact block 905 will break the material through the conical end at the bottom. At this time, the rotating block 702 is squeezed back into the groove 701 by the material. When the impact block 905 rises, the rotating block 702 and the folded plastic film 703 unfold under the rising potential energy and the friction of the material, and grab the blocked material nearby and re-stir it, which directly solves the problem of material blockage.
