Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 , the utility model provides an embodiment: a filtering device for preparing a combined herbicide containing sulfonylurea compounds, comprising a filter box 1, a sealed cabinet door 4 is arranged at the bottom end of one side of the filter box 1, a filter plate 2 is welded at the top end inside the filter box 1, and filter holes 3 are evenly opened inside the filter plate 2, support plates 5 are installed on both sides of the filter box 1 above the filter plate 2, and slide grooves 16 are opened on opposite sides of the support plate 5, and limiting guide rods 14 are arranged on both sides of the support plate 5 with upper and lower intervals, and the outer sleeve of the limiting guide rod 14 on the same side is connected with a guide plate 13, and one side of the guide plate 13 is connected with a movable plate 6;

[0023] The bottom end of the movable plate 6 is connected with a swinging material turning mechanism 11 to turn the herbicide and promote the filtering and falling of the herbicide;

[0024] The swinging material turning mechanism 11 includes two half gears 1101 respectively installed at the bottom ends of the inner sides of the two support plates 5, and the bottom ends of the movable plates 6 above the half gears 1101 are installed with tooth plates 1102, the bottom ends of the tooth plates 1102 are meshed with one side of the half gears 1101, and the side of the half gears 1101 away from the teeth is installed with swinging plates 1103, the bottom ends of the inner sides of the two swinging plates 1103 are connected with connecting rollers 1104, and the bottom ends of the connecting rollers 1104 are against the top ends of the filter plates 2;

[0025] The rotation center of the half gear 1101 is located on the longitudinal extension line of the slide slot 16, and the half gear 1101 reciprocates left and right under the meshing action of the tooth plate 1102;

[0026] The swing axis of the connecting roller 1104 coincides with the cross-sectional axis of the filter plate 2, the length of the connecting roller 1104 is greater than the length of the pressing plate 10, and when the connecting roller 1104 is at the bottom, the pressing plate 10 is at the highest point;

[0027] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, when in use, the movable plate 6 is moved horizontally, and the half gear 1101 is meshed with the tooth plate 1102 to realize the left and right reciprocating swing of the connecting roller 1104, so that the herbicide is turned over, the fluidity of the herbicide is promoted, and the filtering speed is increased. In addition, the connecting roller 1104 and the top of the filter plate 2 are offset against each other, which can also produce a certain grinding effect on large-particle herbicides, thereby reducing the subsequent secondary grinding of the herbicide.

[0028] The movable plates 6 are all facing the inner side of the support plate 5, and guide holes 12 are provided inside the two movable plates 6;

[0029] The cross section of the guide hole 12 is an inverted V shape, and the inner width of the guide hole 12 is adapted to the outer diameter of the lifting rod 7;

[0030] A lifting rod 7 is connected through the guide holes 12;

[0031] The two ends of the lifting rod 7 form an up-and-down sliding structure with the support plate 5 through the cooperation of the slide groove 16, and the movable plate 6 forms a left-and-right sliding structure with the support plate 5 through the mutual cooperation of the guide plate 13 and the limiting guide rod 14;

[0032] Both outer ends of the lifting rod 7 extend to the inside of the slide slot 16, and the guide hole 12 cooperates with the slide slot 16 to realize the up and down reciprocating movement of the lifting rod 7. The outer sleeve of the lifting rod 7 is provided with a fixed sleeve 8, and the bottom end of the fixed sleeve 8 is installed with a connecting rod 9, and the bottom end of the connecting rod 9 is installed with a pressing plate 10, and the curvature of the bottom end of the pressing plate 10 is adapted to the curvature of the top end of the filter plate 2. The side of the support plate 5 away from the movable plate 6 is installed with an electric telescopic rod 15, and one end of the electric telescopic rod 15 is connected to the inner side of the guide plate 13, and the movable plate 6 is driven to move horizontally back and forth left and right through the extension and retraction of the electric telescopic rod 15;

[0033] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when in use, the left and right movement of the guide hole 12 is utilized in conjunction with the guiding effect of the slide groove 16 to cause the lifting rod 7 to move up and down, so that the herbicide can be hammered synchronously during the filtering process, which, on the one hand, promotes the crushing of large particles of herbicide, and on the other hand, promotes the vibration of the herbicide on the filter plate 2, so as to further increase the filtering speed.

[0034] Working principle: When the utility model is used, the herbicide is first poured onto the filter plate 2, and the filter holes 3 are used to make the small-particle herbicide fall directly to the bottom of the filter plate 2, and the large-particle herbicide remains on the top of the filter plate 2, and the sealed cabinet door 4 is opened to facilitate the sieved herbicide to be taken;

[0035] Secondly, during the filtering process, the electric telescopic rod 15 is synchronously started to telescope, so that it pushes the guide plate 13 on one side to slide along the limit guide rod 14, thereby driving the two movable plates 6 to synchronously reciprocate left and right. Since both ends of the lifting rod 7 are located inside the movable plate 6 and are limited and guided by the movable plate 6, the guide hole 12 moves synchronously during the movement of the movable plate 6, so that the guide hole 12 further guides the position of the lifting rod 7, so that the lifting rod 7 reciprocates up and down, and the fixed sleeve 8 drives the connecting rod 9 to move up and down, so that the pressing plate 10 beats the top of the filter plate 2, so that the pressing plate 10 crushes the large particles of herbicide;

[0036] Finally, during the left and right movement of the movable plate 6, the tooth plate 1102 is synchronously driven to move. Since the tooth plate 1102 and the half gear 1101 are meshed with each other, the half gear 1101 rotates to drive the swing plate 1103, so that the connecting roller 1104 flips the herbicide on the top of the filter plate 2 to promote the filtering rate of the herbicide.
