[0044] The following is combined with Figure 1 -Attached Figure 4 The present application is further described in detail. In this embodiment, if not clearly specified, "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, etc., which can be understood according to the specific circumstances. In the absence of any contrary explanation, the directional words used in this application, such as "inside" and "outside", refer to the outline of the corresponding parts themselves.
[0045] like Figure 1 As shown, an embodiment of the present application discloses a screening machine with a drying function (hereinafter referred to as a "screening machine"), which includes a feeding mechanism 1, a heating mechanism 2, a screening mechanism 3, an air supply mechanism 4 and a collecting mechanism, and is used for drying and screening fertilizers.
[0046] like Figure 2-Figure 4 As shown, the feeding mechanism 1 includes a main feeding member 11, a first dividing member 12 and a second dividing member 13, the first end of the first dividing member 12 and the first end of the second dividing member 13 are both connected to the main feeding member 11, the first dividing member 12 is separated from the middle of the second dividing member 13, and the second end of the first dividing member 12 is connected to the second end of the second dividing member 13. The main feeding member 11, the first dividing member 12 and the second dividing member 13 can all be pipeline structures for conveying fertilizer as a material. The first dividing member 12 and the second dividing member 13 can improve the dispersion of the fertilizer by diverting the fertilizer, so that the subsequent heating and drying can be fully carried out to avoid affecting the drying effect due to fertilizer accumulation.
[0047] The feeding mechanism 1 also includes a dividing block 14, which is arranged below the output end of the main feed member 11 and is used to divert the fertilizer so that the first dividing member 12 and the second dividing member 13 are arranged on both sides of the dividing block 14. The dividing block 14 can be a diamond block structure, and the upper end of the dividing block 14 is provided with a protruding sharp corner. The fertilizer in the main feed member 11 hits the protruding sharp corner, so that the fertilizer is diverted to the first dividing member 12 and the second dividing member 13, which improves the dispersion of the fertilizer before heating, helps to make the heating uniform, and optimizes the drying effect. The dividing block 14 can also be an asymmetric structure on both sides, so that the conveying lengths of the first dividing member 12 and the second dividing member 13 are different, further optimizing the dispersion of the fertilizer.
[0048] like Figure 2-Figure 4 As shown, the input end of the heating mechanism 2 is connected to the second end of the first material dividing member 12 and the second end of the second material dividing member 13. The heating mechanism 2 includes a first heating component 21, and the first heating component 21 includes a first conveying member 211 and a first heating member 212. The upper end of the first conveying member 211 is connected to the feeding mechanism 1, and the first conveying member 211 is provided with a hollow first material channel 213, which is used to provide a flow channel for the fertilizer. A first cavity 214 is provided in the side wall of the first conveying member 211, and the first heating member 212 is provided in the first cavity 214. The first heating member 212 can be a resistance wire. The first heating member 212 is arranged circumferentially in the first material channel 213, which can increase the heating area and optimize the heating effect on the fertilizer.
[0049] A first support plate 215 and a second support plate 216 are provided on one side of the side wall of the first conveying member 211 close to the first material channel 213. The first support plate 215 and the second support plate 216 are arranged on opposite sides of the first conveying member 211.

The first support plate 215 and the second support plate 216 are arranged alternately so that the conveying path of the fertilizer in the first material channel 213 is extended, thereby extending the heating time and optimizing the heating effect.
[0050] like Figure 2-Figure 4 As shown, the heating mechanism 2 also includes a second heating component 22, and the second heating component 22 includes a second conveying member 221 and a second heating member 222. The second conveying member 221 is provided with a hollow second material channel 223, and the second conveying member 221 is inclined to slow down the passing speed of the fertilizer and prolong the residence time of the fertilizer. The side wall of the second conveying member 221 is provided with a second cavity 224, and the second heating member 222 is arranged in the second cavity 224. The upper end of the second conveying member 221 is connected to the lower end of the first conveying member 211, so as to perform secondary heating on the basis of the first heating component 21 and optimize the heating effect. The second heating member 222 can be a resistance wire or other structure that can achieve heating, and the second heating member 222 is arranged around the circumference of the second material channel 223.
[0051] like Figure 2-Figure 4 As shown, the screening mechanism 3 is connected to the output end of the heating mechanism 2. The air supply mechanism 4 is connected to the screening mechanism 3, and the air supply mechanism 4 is used to blow air into the screening mechanism 3. On the one hand, the heating and blowing functions are set separately, which can blow away the hot air generated by the heating to avoid the hot air being re-adsorbed in the fertilizer to increase the risk of agglomeration; on the other hand, after the second heating, if the fertilizer is too dry, the fertilizer will quickly absorb moisture in the air, affecting the drying effect. At this time, the air-drying method that accelerates the air flow helps to ensure the drying effect. The air supply mechanism 4 can be a blower or a fan structure.
[0052] like Figure 2-Figure 4 As shown, the screening mechanism 3 includes a first screening plate 31 and a second screening plate 32. The first screening plate 31 and the second screening plate 32 are both inclined, and the inclination directions of the first screening plate 31 and the second screening plate 32 are opposite, so that fertilizers of different particle sizes flow to different directions respectively, reducing the risk of confusion during collection. The screening particle size of the first screening plate 31 is larger than the screening particle size of the second screening plate 32. The first screening plate 31 is arranged below the output end of the heating mechanism 2, and the second screening plate 32 is arranged below the first screening plate 31, so that the fertilizer can be screened into three different particle sizes, thereby improving the fineness of fertilizer screening.
[0053] like Figure 2-Figure 4 As shown, the screening mechanism 3 further includes a screening box 33, a first adjusting member 34 and a second adjusting member 35, and the first screening plate 31 and the second screening plate 32 are both arranged in the screening box 33. The first adjusting member 34 is connected to the first screening plate 31, and the first adjusting member 34 is used to adjust the inclination angle of the first screening plate 31; the second adjusting member 35 is connected to the second screening plate 32, and the second adjusting member 35 is used to adjust the inclination angle of the second screening plate 32.
[0054] The first adjusting member 34 and the second adjusting member 35 can be a cylinder, a hydraulic cylinder or a telescopic rod structure. One end of the first screening plate 31 is rotatably connected to the screening box 33, and the other end of the first screening plate 31 is provided with a first mounting groove, in which the first elastic member 312 is connected, one end of the first elastic member 312 is connected to the bottom of the first mounting groove, and the other end of the first elastic member 312 is connected to the first adjusting plate 313, and both sides of the first adjusting plate 313 are slidably connected to the first screening plate 31, so that the first adjusting plate 313 can be extended and retracted in the first mounting groove, so that the overall length of the first screening plate 31 can be adjusted accordingly when the tilt angle is adjusted. The first adjusting plate 313 is rotatably connected to the movable end of the first adjusting member 34, so that the vertical extension and retraction of the first adjusting member 34 can be converted into the rotation of the first screening plate 31 around one end thereof, so as to adjust the tilt angle. Similarly, the second screening plate 32 is provided with a second mounting groove, in which a second elastic member 322 and a second adjusting plate 323 are provided, and the connection and tilt angle adjustment principle thereof are similar to those of the first screening plate 31, and will not be described in detail here. According to the type of fertilizer, the first adjusting member 34 and the second adjusting member 35 are adjusted, so as to reasonably set the tilt angles of the first screening plate 31 and the second screening plate 32 to ensure the screening effect of the fertilizer.
[0055] like Figure 2-Figure 4 As shown, the first screening plate 31 is provided with a first vibrator 311, and the second screening plate 32 is provided with a second vibrator 321. The vibration frequency of the first vibrator 311 is greater than the vibration frequency of the second vibrator 321. Vibration is used to accelerate the screening efficiency of fertilizers, and different vibration frequencies are reasonably adopted according to the weight of different particle sizes to optimize the screening effect and reduce energy consumption. The number and location of the first vibrator 311 and the second vibrator 321 can be set as needed, such as being symmetrically arranged on both sides of the screening box 33 to optimize the screening effect.
[0056] like Figure 2-Figure 4 As shown, the collecting mechanism is arranged at the output end of the screening mechanism 3. The collecting mechanism includes a collecting box 51 and a collecting member 52, the two collecting members 52 are respectively connected to the output end of the first screening plate 31 and the output end of the second screening plate 32, and the collecting box 51 is arranged below the second screening plate 32 to collect fertilizers of different particle sizes respectively, thereby completing the screening of the fertilizers.
[0057] The collecting member 52 comprises a collecting box 521 and a cover 522. The connecting end of the cover 522 is rotatably connected to the collecting box 521. The cover 522 is selectively rotated to a vertical or horizontal state. The connecting end of the cover 522 is arranged on a side of the collecting box 521 away from the screening mechanism 3. When the cover 522 is opened vertically, it can prevent the fertilizer from rushing out of the collecting box 521. After the collection is completed, the collecting box 521 can be closed by rotating the cover 522 to a horizontal state, thereby improving the reliability of the collection.
[0058] The implementation principle of a screening machine with a drying function in an embodiment of the present application is as follows: the fertilizer enters the screening machine through the main feeding part 11, and is divided by the first dividing part 12 and the second dividing part 13 to improve the dispersion, thereby optimizing the heating and drying effect when entering the heating mechanism 2 and reducing the possibility of fertilizer agglomeration; the fertilizer is heated and dried in turn by the first heating component 21 and the second heating component 22 and enters the screening mechanism 3 to optimize the screening effect; and, air is blown in the screening mechanism 3 through the air supply mechanism 4 to further keep the fertilizer dry, and the fertilizer screened by the screening mechanism 3 is collected by the collecting mechanism to realize separate collection of fertilizers of different particle sizes, thereby realizing reliable screening of the fertilizer.
