[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0024] Please refer to Figures 1-4, A rice processing feeder, including a conveyor body 1. A drying device 13 is arranged at the rear side in the conveyor body 1. An installation frame 2 is arranged in the middle of the conveyor body 1. A moisture following detection device 3 is arranged on the installation frame 2. A fork-type moisture meter 31 (using existing technology) is installed at the bottom of the moisture following detection device 3. The moisture following detection device 3 drives the fork-type moisture meter 31 to intermittently move downwards and insert into the rice on the conveyor belt 12 in the conveyor body 1, and moves with the rice during the detection. After the detection is completed, the fork-type moisture meter 31 is lifted up and then moved back to the reset position. A controller is arranged on the conveyor body 1. The sensor in the fork-type moisture meter 31 is connected to the drying device 13. The moisture data detected by the sensor is fed back to the controller and used to control whether the drying device 13 is turned on or off; The moisture following detection device 3 includes a long gear 32 rotatably installed on the installation frame 2 and a vertical rack 33 engaged with the long gear 32. A motor one connected to the long gear 32 is fixed on the installation frame 2. The long gear 32 is driven to rotate by the motor one. At the same time, the fork-type moisture meter 31 is fixed at the bottom of the vertical rack 33. The up and down movement of the vertical rack 33 can be controlled by the forward and reverse rotation of the long gear 32. At the same time, due to the setting of the long gear 32, the vertical rack 33 can also move horizontally along the long gear 32. During use, first, the long gear 32 is rotated to drive the vertical rack 33 to move downwards to push the test head at the bottom of the fork-type moisture meter 31 into the rice on the conveyor belt 12. At this time, the long gear 32 stops rotating, and the fork-type moisture meter 31 moves with the subsequent moving rice, so that the fork-type moisture meter 31 is relatively stationary with the detection point. After the detection is completed, the long gear 32 is rotated again to lift the fork-type moisture meter 31 out of the rice;
[0025] The moisture following detection device 3 further includes a non-slip belt 34 rotatably arranged on the installation frame 2. Multiple sets of belt pulleys 35 are rotatably arranged on the installation frame 2. The belt 34 is sleeved on the multiple sets of belt pulleys 35. One set of belt pulleys 35 is fixedly connected to the output shaft of a motor two fixed on the installation frame 2. The rotation direction of the belt 34 driven by the motor two is the same as that of the conveyor belt 12. A reset connecting piece 36 is fixed on the vertical rack 33. The reset connecting piece 36 intermittently contacts the bottom side section of the belt 34 in a non-slip manner, that is, after the fork-type moisture meter 31 is lifted out of the rice, the reset connecting piece 36 moves upwards to contact the bottom side section of the belt 34, so as to drive the fork-type moisture meter 31 to move forward and reset by using the belt 34.
[0026] Please refer to Figures 3-4, Rice processing feeder. The rotation speed of the motor two driving the belt 34 is the same as that of the conveyor belt 12. At the same time, a following contact member 37 is fixed above the reset connecting member 36 on the vertical rack 33. The following contact member 37 intermittently makes anti-slip contact with the top side section of the belt 34. That is, when the fork-type moisture meter 31 moves downward and inserts into the rice, the following contact member 37 moves downward and contacts the top side section of the belt 34, so as to drive the fork-type moisture meter 31 to move backward and move synchronously with the conveyor belt 12 by using the belt 34, realizing the relative static state between the fork-type moisture meter 31 and the test point, and ensuring the stability of the fork-type moisture meter 31 following the movement of the rice. The motor one and the motor two are also electrically connected to the controller. By controlling the working states of the motor one and the motor two through the controller, when the rice poured from the bag onto the conveyor belt 12 passes under the fork-type moisture meter 31, the fork-type moisture meter 31 moves downward and inserts into the rice for detection. If the moisture content exceeds the standard, the drying device 13 can be started through the controller to dry this batch of rice.
[0027] Please refer to Figures 1-2 , Rice processing feeder. Above the conveyor belt 12 on the conveyor body 1, and evenly distributed rake teeth are fixed on the inlet side of the drying device 13. The rice before drying after detection is raked evenly through the evenly distributed rake teeth to improve the drying effect.
[0028] Please refer to Figure 3 , Rice processing feeder. A horizontally placed sliding rod 38 parallel to the long gear 32 is fixed on the mounting frame 2. A sliding sleeve 39 also slides on the horizontally placed sliding rod 38. A long hole 331 for the horizontally placed sliding rod 38 to pass through is provided on the vertical rack 33, and the vertical rack 33 is vertically slidably connected to the sliding sleeve 39. The setting of the long hole 331 enables the vertical rack 33 to not only slide horizontally along the horizontally placed sliding rod 38, but also slide vertically along the horizontally placed sliding rod 38. The cooperation between the horizontally placed sliding rod 38 and the sliding sleeve 39 provides stable support for the moving vertical rack 33.
[0029] Please refer to Figures 1-2 , Rice processing feeder. There is a convex platform 11 at the front end of the conveyor body 1 with a height higher than the conveyor belt 12 in the conveyor body 1. The convex platform 11 is used to place the packaging bag. After the bagged rice is placed on the convex platform 11, the tying mouth is untied or cut open, and then the rice is poured onto the conveyor belt 12.
