Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of precious metal smelting, and particularly relates to a precious metal smelting leaching device. BACKGROUND

[0002] The existing precious metal smelting leaching uses a thickener for solid-liquid separation. The thickener realizes solid-liquid separation through physical sedimentation. The core principle is to use the difference in specific gravity between solid particles and liquid to make the solid particles settle to the bottom of the equipment under the action of gravity, and the clarified water overflows from the top.

[0003] In the use process of the existing thickener, after the ore pulp enters the thickening tank, the material can be uniformly distributed by the distribution barrel, and the material can be precipitated at the bottom of the thickening tank, thereby forming a high-concentration underflow. If the high-concentration underflow is not timely pumped away, it will gradually accumulate at the bottom of the thickening tank, thereby increasing the resistance of the rake frame during rotation, and also increasing the pressure when the thickener is lifted. Further, as the degree of accumulation of high-concentration ore pulp at the bottom of the thickening tank deepens, not only the rake teeth may be buried, but also the high-concentration slurry may easily form a hardening at the bottom of the thickening tank. The hardening not only hinders the rotation of the rake frame in the thickening tank, but also may even cause the rake to be pressed. SUMMARY

[0011] Among them, the bottom end of the first inclined groove is closer to the rotating shaft than the top end, and the top end of the second inclined groove is closer to the rotating shaft than the bottom end.

[0012] When the first guide rod moves along the bottom end of the first inclined groove towards the top end of the first inclined groove, the nozzle of the first nozzle gradually deviates from the central axis of the tank body while facing the inner bottom surface of the tank body.

[0013] Further, among the plurality of rake teeth uniformly distributed on the rake frame, from the outside of the tank body to the inside of the tank body, the lengths of the first inclined groove and the second inclined groove in the plurality of first combined guide grooves gradually decrease.

[0019] The present application has the following advantages:

[0020] The present application has the following advantages:

[0021] During the process of injecting material into the tank through the feed pipe, an external air pump supplies air to the first nozzle. When the first nozzle sprays air into the tank, its nozzle faces the bottom surface of the tank, thereby disturbing the material settled in the area traversed by the rake frame. The rotatable design of the first nozzle can blow the material settled on the bottom surface of the tank toward the tank outlet, so that the more concentrated material can be drawn away from the tank outlet. Moreover, since the rake teeth are elastically mounted on the mounting rod, the thrust of the first nozzle when spraying air can drive the rake teeth to approach the rake frame on the mounting rod. Therefore, during the spraying process, the first nozzle can disturb the material settled in a larger area on the bottom surface of the tank, further reducing the amount of material accumulated and settled in the area traversed by the rake frame. This not only helps the rake frame rotate normally and reduces the probability of the rake being pressed down, but also increases the output of the invention.

[0022] Furthermore, the slope of the first inclined chute is greater than that of the second inclined chute, which makes the first guide rod on the first nozzle slide in the first inclined chute for a longer time than it slides in the second inclined chute. This allows the first nozzle to blow material closer to the rotating shaft for a longer period of time, thereby blowing as much material as possible towards the rotating shaft and allowing more material to be discharged from the outlet.

[0023] Furthermore, the lengths of the first and second inclined troughs in the first combination guide grooves corresponding to the multiple rake teeth decrease sequentially along the length direction of the rake frame. This results in the first nozzle's rotation amplitude gradually decreasing from the outside of the tank to the inside of the tank along the length direction of the rake frame. The larger the rotation angle of the first nozzle, the larger the range of material blown by the first nozzle, thus allowing more material to be blown towards the rotating shaft. The gradually shortening lengths of the first and second inclined troughs prevent the first nozzle near the rotating shaft from blowing material over the shaft to the other side, thus avoiding a reduction in material conveying efficiency.

[0024] Furthermore, the second nozzle, which is located on the side of the rake teeth away from the first nozzle, can rotate when the second elastic guide connected to it slides in the second combined guide groove. When rotating, the second nozzle is configured by the second limiting shaft to face the mounting side of the first nozzle located on the other rake tooth behind it. When the second nozzle sprays air, it can clean the rake teeth behind it, preventing material from accumulating on the mounting surface of the first nozzle on the rake teeth behind the second nozzle, thereby reducing the possibility of the first nozzle getting stuck.

[0044] As shown in Figures 1 to 14 The present application provides a noble metal smelting leaching device, which comprises a tank body 110, a rake frame 200 and rake teeth 300. The tank body 110 is a coverless metal tank for containing ore slurry and has a conical bottom surface. The tank body 110 is installed on a support 100, which is a metal support 100. The tank body 110 is provided with a feeding pipe 120 and a cross frame 130. The feeding pipe 120 is installed at the bottom of the cross frame 130 and opens into the tank body 110, used for injecting ore slurry into the tank body 110. The cross frame 130 is a metal frame, which is arranged horizontally on the tank body 110 and passes through the central axis of the tank body 110. The cross frame 130 is rotatably provided with a rotating shaft 131 and a driving member 140 for driving the rotating shaft 131 to rotate. The driving member 140 can be a motor installed on the cross frame 130. The output shaft of the motor is coaxially arranged with the rotating shaft 131, the tank body 110 and the output shaft of the motor. The output shaft of the motor is fixedly connected with the rotating shaft 131 and extends towards the tank body 110 on the cross frame 130. The end of the rotating shaft 131 away from the driving member 140 extends into the tank body 110 and is close to the inner bottom surface of the tank body 110. A discharge port 111 is formed at the center of the bottom of the tank body 110, and a pump is arranged at the discharge port 111. The pump can extract the ore slurry in the tank body 110 and supply it to other use positions through a pipeline.

[0045] The rake frame 200 is a long straight rod arranged in the tank body 110 and parallel to the inner bottom surface of the tank body 110. A plurality of rake frames 200 are arranged in the tank body 110. The plurality of rake frames 200 are fixed on the rotating shaft 131 and uniformly distributed around the circumference of the rotating shaft 131. A plurality of installation rods 210 are fixed on the rake frame 200 along the length direction of the rake frame 200 and perpendicular to the rake frame 200. The plurality of installation rods 210 are parallel to each other on the rake frame 200 and located on the side of the rake frame 200 facing the inner bottom surface of the tank body 110.

[0046] The rake tooth 300 is elastically arranged at the lower part of the mounting rod 210. The length direction of the rake tooth 300 is perpendicular to the length direction of the mounting rod 210, and is arranged obliquely relative to the rake frame 200, and the length direction of the rake tooth 300 forms an angle with the length direction of the rake frame 200. The rake tooth 300 is a combined structure member spliced by two plates, and has a cavity inside. The end of the mounting rod 210 away from the rake frame 200 penetrates through the upper end surface of the rake tooth 300 and extends into the cavity inside the rake tooth 300. The part of the rod body of the mounting rod 210 inserted into the rake tooth 300 is provided with a tab for preventing the mounting rod 210 from being separated from the rake tooth 300. A spring is sleeved on the mounting rod 210, and the two ends of the spring are connected with the rake tooth 300 and the rake frame 200 respectively, so that the spring is arranged to elastically arrange the rake tooth 300 at the lower part of the mounting rod 210.

[0047] The side of the rake tooth 300 facing the rotating direction of the rotating shaft 131 is provided with a first spray head 310. Specifically, a ball groove is formed in the side plate of the side of the rake tooth 300 facing the rotating direction of the rotating shaft 131. The first spray head 310 is a spherical spray head, and the first spray head 310 is rotatably arranged in the ball groove. The rake tooth 300 is provided with a pipeline connected with a gas supply device such as an external air pump. The spray pipe of the first spray head 310 is connected with the pipeline arranged in the rake tooth 300.

[0048] In the present application, the spray opening of the first spray head 310 faces the bottom surface of the tank body 110, and the first spray head 310 can rotate in the corresponding ball groove. When the first spray head 310 rotates with the rake tooth 300, the rake frame 200 and the rotating shaft 131, the first spray head 310 can blow the material deposited on the bottom surface of the tank body 110, and the first spray head 310 can also blow the material close to the outside of the tank body 110 to the side close to the rotating shaft 131 when rotating, thereby accelerating the flow of the material to the discharge port 111 at the bottom of the tank body 110, and facilitating the discharge of the material.

[0049] The operation principle of the present application is as follows:

[0050] Firstly, the to-be-deposited material is introduced into the tank body 110 through the feeding pipe 120, and the material in the tank body 110 is settled. Then, the rake frame 200 is driven to rotate by the driving member 140. After that, the pump arranged at the position of the discharge port 111 at the bottom of the tank body 110 is used to pump the material with high concentration deposited at the discharge port 111 away from the tank body 110, so as to realize the output of the deposited material.

[0051] When the material in the tank body 110 is settled, in order to avoid the settlement of the material to form a hardening layer at the bottom of the tank body 110 and to avoid the phenomenon of pressing the rake, during the process of injecting the material into the tank body 110 through the feeding pipe 120, the first spray head 310 is inflated through the external air pump and the pipeline connected between the external air pump and the first spray head 310.

[0052] The first spray head 310 can spray air towards the inner bottom surface of the tank body 110, thereby being able to disturb the material accumulated on the bottom surface of the tank body 110, reducing the possibility of material being hardened on the bottom surface of the tank body 110. Moreover, the first spray head 310 can be pushed to move in a direction parallel to the mounting rod 210 and away from the bottom of the tank body 110 due to the reaction force of the spray end of the first spray head 310 when spraying air, thereby making the area of the bottom surface of the tank body 110 that can be blown by the first spray head 310 larger. In addition, since the first spray head 310 can rotate, when the first spray head 310 rotates with the rotating shaft 131, the first spray head 310 can blow the material on the bottom surface of the tank body 110 towards the discharge port 111 of the tank body 110, which is more convenient for the output of the material from the discharge port 111, thereby reducing the accumulation of material in the tank body 110, facilitating the rotation of the rake frame 200, reducing the probability of the present application being pressed, and improving the output of the present application.

[0053] Further, the rake tooth 300 is provided with a first limiting shaft 320. A first limiting groove 301 is formed on the side plate of the side of the rake tooth 300 on which the first spray head 310 is mounted, and the first limiting groove 301 is communicated with the ball groove on which the first spray head 310 is mounted. The first limiting groove 301 is inclined relative to the rake tooth 300, and one end thereof communicated with the ball groove is close to the side of the first spray head 310 extending out of the rake tooth 300, and the other end extends towards the inside of the rake tooth 300. The first limiting shaft 320 is mounted in the first limiting groove 301, and the first limiting shaft 320 can limit the direction of the first spray head 310, so that the spray port of the first spray head 310 always faces the bottom surface of the tank body 110, thereby facilitating the blowing of the first spray head 310 to the bottom surface of the tank body 110 and reducing the possibility of material being hardened on the bottom surface of the tank body 110. At the same time, when the first spray head 310 rotates, the first limiting shaft 320 can also limit the first spray head 310 to rotate only around the first limiting shaft 320, so that the first spray head 310 can blow the material close to the outside of the tank body 110 to the side close to the rotating shaft 131 when rotating, which is beneficial to the output of the material in the tank body 110 and reduces the possibility of the present embodiment being pressed.

[0054] In some embodiments, one end of the mounting rod 210 is inserted into the rake tooth 300, and a first combined guide groove 400 is formed on the part of the rod body side wall of the mounting rod 210 inserted into the rake tooth 300. The first combined guide groove 400 faces the first spray head 310. The first spray head 310 is provided with a first elastic guide piece 330, which is a top support structure piece with a certain elasticity. One end of the first elastic guide piece 330 away from the first spray head 310 extends into the first combined guide groove 400. The first combined guide groove 400 is configured to provide a movement interval for the movement of the first elastic guide piece 330. During the movement of the first elastic guide piece 330 along the first combined guide groove 400, the first spray head 310 can rotate, which is beneficial to the discharge of the material on the bottom side of the tank body 110.

[0055] Further, the first positioning slot is arranged on the first spray head 310, the first elastic guide 330 comprises a first guide rod 331 and a first spring 332, one end of the first guide rod 331 is inserted into the first positioning slot, the other end of the first guide rod 331 is inserted into the first combined guide slot 400, the first spring 332 is located in the first positioning slot, and the two ends of the first spring 332 are fixedly connected with the bottom of the first positioning slot and the first guide rod 331 respectively, and the first elastic member is configured to provide the first guide rod 331 with an elastic force always acting on the corresponding first combined guide slot 400.

[0056] In the embodiment, when the first spray head 310 sprays air, the first spray head 310 can be subjected to a reverse thrust of the air flow, thereby pushing the rake tooth 300 to move along the length direction of the mounting rod 210 to approach the rake frame 200, and in the process of approaching the rake frame 200, the one end of the first guide rod 331 on the first spray head 310 can move relative to the first combined guide slot 400.

[0057] The end of the first guide rod 331 inserted into the first combined guide slot 400 can be a ball head end, when the ball head end of the first guide rod 331 moves relative to the first combined guide slot 400, the first spray head 310 can be driven to rotate around the corresponding first limiting shaft 320. The rotatable arrangement of the first spray head 310 enables the first spray head 310 to blow air to multiple regions of the inner bottom surface of the tank body 110 in the process of approaching the rake frame 200, thereby improving the disturbance efficiency of the material accumulated on the inner bottom surface of the tank body 110, dispersing the deposited material in the rotating region of the rake frame 200, and further reducing the resistance of the rake tooth 300 during rotation, thereby reducing the probability of the present application of the rake pressing phenomenon, and being beneficial to ensure the normal implementation of the present application.

[0058] In some embodiments, the first combined guide slot 400 comprises a first inclined slot 410, a second inclined slot 420 and a first straight slot 430, the first inclined slot 410 is located below the second inclined slot 420, and the first inclined slot 410 and the second inclined slot 420 are respectively close to the bottom end and the top end of the part of the rod body of the mounting rod 210 extending into the rake tooth 300. The inclination directions of the first inclined slot 410 and the second inclined slot 420 are opposite, and the inclination of the first inclined slot 410 is greater than the inclination of the second inclined slot 420, the first straight slot 430 is a slot body parallel to the length direction of the mounting rod 210, and the first straight slot 430 connects the two ends of the first inclined slot 410 and the second inclined slot 420 close to each other and away from each other, so that the first inclined slot 410, the second inclined slot 420 and the first straight slot 430 form a communication slot.

[0059] Specifically, the first chute 410 and the second chute 420 are both straight chutes, the cross section of the chute body can be a tapered chute body, a truncated cone chute body or the like, and the first guide rod 331 can be a ball head end at one end of the first chute 410 and the second chute 420. When the ball head end of the first guide rod 331 abuts against the first chute 410 or the second chute 420, if the first nozzle 310 can be pushed to move in the direction close to the rake frame 200 by the reaction force when the first nozzle 310 sprays air, the first guide rod 331 will slide in the corresponding chute body, and when sliding, the first guide rod 331 will be affected by the inclination direction of the first chute 410 and the second chute 420, so that the first guide rod 331 is deflected, and the first nozzle 310 is driven to rotate at the installation position, so that the direction of the nozzle of the first nozzle 310 is changed, and the area of the first nozzle 310 blowing to the inner bottom surface of the tank 110 is changed, so that the disturbance efficiency of the first nozzle 310 to the material in the tank 110 is improved.

[0060] In the embodiment, the first chute 410 is located below the second chute 420, the bottom end of the first chute 410 is closer to the rotating shaft 131 than the top end, and the top end of the second chute 420 is closer to the rotating shaft 131 than the bottom end. The first straight chute 430 can be provided with two, and the two first straight chutes 430 are respectively connected to the two ends close to each other and the two ends away from each other of the first chute 410 and the second chute 420, so that the first chute 410, the second chute 420 and the first straight chute 430 form a complete communication chute.

[0061] The first chute 410 and the second chute 420 can be provided as a group, and the first straight chute 430 connects the two ends close to each other of the first chute 410 and the second chute 420 in the same group. In the embodiment, the first chute 410 and the second chute 420 in the first combined guide chute 400 can be provided with more than one group, and the first chute 410 and the second chute 420 in more than one group are arranged in sequence from top to bottom along the length direction of the mounting rod 210, and the first straight chute 430 is communicated between the two adjacent groups of the first chute 410 and the second chute 420.

[0062] For example, assume that the first inclined groove 410 and the second inclined groove 420 in the first combination guide groove 400 are provided with two groups, respectively defined as a first group and a second group, wherein in the length direction of the mounting rod 210, the first group is located above the second group. The first inclined groove 410 of the first group and the second inclined groove 420 of the second group are close to each other, and the two ends close to each other are connected by the first straight groove 430, so that the two groups of the first inclined groove 410 and the second inclined groove 420 can form a continuous groove approximately in the shape of S, while the second inclined groove 420 of the first group and the first inclined groove 410 of the second group are away from each other, and the two ends away from each other are also connected by the first straight groove 430, thereby forming a closed through groove in the shape of S. When the first guide rod 331 slides along the two groups of the first inclined groove 410 and the second inclined groove 420 connected, it can drive the first nozzle 310 to repeatedly rotate around the first limiting shaft 320, and can realize the disturbance of the first nozzle 310 to the material on the bottom surface of the tank 110, and can reduce the possibility of the pressure rake.

[0063] In this embodiment, during the process of the end of the first guide rod 331 sliding from the bottom end of the first inclined groove 410 to the top end of the first inclined groove 410, the first guide rod 331 can push the first nozzle 310 to rotate towards the direction close to the rotating shaft 131, thereby enabling the material deposited at the bottom of the tank 110 to be blown to the discharge port 111 of the tank 110.

[0064] In this embodiment, the tines 300 are arranged on the side of the rake frame 200 close to the inner bottom surface of the tank 110 through the mounting rod 210, and the inclination direction of the tines 300 relative to the rake frame 200 is related to the direction of rotation of the rake frame 200 in the tank 110, wherein the nozzle of the first nozzle 310 on the tine 300 not only faces the inner bottom surface of the tank 110, but also faces the direction of rotation of the rotating shaft 131.

[0065] When the rake frame 200 rotates, it can push the material in the tank 110 to flow. When the first guide rod 331 slides along the first inclined groove 410, the first nozzle 310 blows the material close to the side wall of the tank 110 to the side close to the rotating shaft 131. When the direction of the rake frame 200 pushing the material to flow coincides with the direction of the first nozzle 310 blowing the material, the rotation of the rake frame 200 can promote the blowing of the material by the first nozzle 310, thereby reducing the resistance of the material moving towards the rotating shaft 131 and the discharge port 111, and accelerating the output of the material.

[0066] As Figure 12is a top view of the hidden horizontal frame 130 and the driving member 140 in the application, when the rotating shaft 131 in the application rotates clockwise, the rake teeth 300 on the rake frame 200 are arranged obliquely in this view, and in the rotating direction of the rotating shaft 131, the end of the rake teeth 300 on the front side of the direction is higher than the end on the rear side of the direction. Since the rake frame 200 in the application is parallel to the inner bottom surface of the tank body 110, and the rake teeth 300 are uniformly arranged along the length direction of the rake frame 200, the rake teeth 300 are also arranged in the direction parallel to the inner bottom surface of the tank body 110. Therefore, the inner bottom surface of the tank body 110 is a conical surface, so the end of the rake teeth 300 close to the rotating shaft 131 is lower than the end away from the rotating shaft 131 in the direction relative to the axial direction of the rotating shaft 131.

[0067] In the rotating direction of the rotating shaft 131, the first nozzle 310 is located on the front side plate of the rake teeth 300. The bottom end of the first inclined groove 410 opened on the side of the mounting rod 210 towards the first nozzle 310 is closer to the rotating shaft 131 than the top end of the first inclined groove 410, and the top end of the second inclined groove 420 is closer to the rotating shaft 131 than the bottom end of the second inclined groove 420. Further, the blowing direction of the first nozzle 310 is from the side wall of the tank body 110 towards the rotating shaft 131 during the movement of the corresponding guide rod of the first nozzle 310 along the first inclined groove 410 towards the second inclined groove 420, that is, the first nozzle 310 can blow the material close to the side wall of the tank body 110 towards the side close to the rotating shaft 131. The rotating direction of the first nozzle 310 has a sub-direction in the clockwise rotating direction of the rotating shaft 131, that is, the clockwise rotating direction of the rake frame 200 coincides with the direction of the first nozzle 310 rotating towards the rotating shaft 131, so that the first nozzle 310 can promote the blowing of the material towards the side close to the rotating shaft 131 when the rake frame 200 rotates, which is more conducive to the material entering the discharge port 111 of the tank body 110 and facilitating the discharge of the material.

[0068] At the same time, since the slope of the first inclined groove 410 is greater than the slope of the second inclined groove 420, the time for the guide rod on the first nozzle 310 to slide in the first inclined groove 410 is longer than the time for the guide rod to slide in the second inclined groove 420, so that the first nozzle 310 blows the material towards the side close to the rotating shaft 131 for a longer time and blows more material, and the first nozzle 310 blows the material away from the rotating shaft 131 for a shorter time and blows less material. The less material blown towards the side close to the side wall of the tank body 110, the less impact on the normal operation of the application, which can ensure the normal implementation of the application.

[0069] When the first guide rod 331 slides to the top end of the second chute 420, the first nozzle 310 stops blowing, at this time the first guide rod 331 can slide along the first straight chute 430 to the bottom end of the first chute 410, that is, the initial position. Then the first nozzle 310 is turned on again, and the first nozzle 310 and the first guide rod 331 repeat the above movement, not only achieving the disturbance of the material at the bottom of the tank body 110, reducing the probability of the occurrence of the rake phenomenon, but also blowing more material to the discharge port 111 of the tank body 110, facilitating the conveying of the material.

[0070] Of course, in some embodiments, in the case of Figure 12 The rotation direction of the rotating shaft 131 can also be counterclockwise rotation under the viewing angle shown. Counterclockwise rotation makes the orientation of the first nozzle 310 and the orientation of the rake tooth 300 opposite to that when the rotating shaft 131 rotates clockwise. The orientations of the first chute 410 and the second chute 420 remain unchanged, and when the first guide rod 331 slides along the first chute 410, it can still blow the material close to the side wall of the tank body 110 to the side close to the rotating shaft 131. The above embodiment is only an embodiment of the present application when the rotating shaft 131 rotates clockwise.

[0071] In some embodiments, among the plurality of rake teeth 300 uniformly distributed on the rake frame 200, the lengths of the first chute 410 and the second chute 420 in the first combined guide groove 400 gradually decrease from the outside of the tank body 110 to the inside of the tank body 110.

[0072] The longer the lengths of the first chute 410 and the second chute 420, the greater the deflection angle of the corresponding first nozzle 310, the greater the rotation angle of the first nozzle 310, and the greater the range of the material blown by the first nozzle 310, thereby blowing more material to the rotating shaft 131. The gradually decreasing length of the first chute 410 and the second chute 420 can avoid the first nozzle 310 close to the rotating shaft 131 blowing the material too much to the other side of the rotating shaft 131 when blowing the material, thereby reducing the conveying efficiency of the material.

[0073] In other embodiments, a second nozzle 340 and a second limiting shaft 321 are arranged on the side plate of the rake tooth 300 opposite to the first nozzle 310. The second nozzle 340 is similar to the first nozzle 310, which is also a spherical nozzle, and the second nozzle 340 is configured to rotate on the rake tooth 300 about the second limiting shaft 321. In the rotation direction of the rotating shaft 131, the second limiting shaft 321 is configured to limit the direction of the nozzle of the second nozzle 340 to be directed to another rake tooth 300 located behind the second nozzle 340.

[0074] Specifically, the tine 300 is provided with a ball groove on the side plate away from the first nozzle 310, the second nozzle 340 is installed in the ball groove, and the side plate is provided with a second limiting groove 302 communicating with the ball groove, the second limiting shaft 321 is installed in the second limiting groove 302, and the side plate is also provided with a pipeline connected to the second nozzle 340, and the pipeline away from the second nozzle 340 can be connected with the same air pump as the pipeline of the first nozzle 310. In the rotation direction of the rotating shaft 131, the second nozzle 340 can flush away the material accumulated on the mounting surface of the first nozzle 310 of the other tine 300 located behind the second nozzle 340 when the second nozzle 340 sprays, so as to avoid affecting the normal rotation of the first nozzle 310.

[0075] Further, the mounting rod 210 is provided with a second combined guide groove 500 symmetrical to the first combined guide groove 400 about the mounting rod 210 on the side away from the first combined guide groove 400, and the second nozzle 340 is provided with a second elastic guide 350. The second combined guide groove 500 is configured to provide a movement range for the movement of the second elastic guide 350, and in the movement process of the second elastic guide 350 along the second guide groove, the nozzle of the second nozzle 340 can sweep the other tine 300 located behind the second nozzle 340 and the mounting side of the first nozzle 310 on the corresponding tine 300.

[0076] In the process of moving the tine 300 on the mounting rod 210 by the first nozzle 310, the second elastic guide 350 on the side plate of the tine 300 where the second nozzle 340 is located can guide the second nozzle 340 to slide along the second combined guide groove 500, and in the sliding process, the second nozzle 340 can be rotated around the corresponding second limiting shaft 321. When the second nozzle 340 rotates, the nozzle thereof can flush the other tine 300 located behind the second nozzle 340, specifically the mounting side of the first nozzle 310 of the other tine 300.

[0077] In the embodiment, the second combined guide slot 500 is symmetrical to the first combined guide slot 400 about the mounting rod 210, and thus the second combined guide slot 500 comprises a third inclined slot 510, a fourth inclined slot 520, and a second straight slot 530, wherein the third inclined slot 510 is symmetrical to the first inclined slot 410 in the first combined guide slot 400, the fourth inclined slot 520 is symmetrical to the second inclined slot 420 in the first combined guide slot 400, and the second straight slot 530 is symmetrical to the first straight slot 430 in the first combined guide slot 400. Since the second nozzle 340 is mounted on the two sides of the tine 300 respectively, when the second elastic guide piece 350 of the second nozzle 340 slides along the corresponding third inclined slot 510, the second nozzle 340 can blow the material on the tine 300 at the rear side of the second nozzle 340 and the material between the tine 300 at the rear side and the current tine 300 in the rotation direction of the rotating shaft 131, and blow the material to the direction close to the rotating shaft 131. When the second elastic guide piece 350 of the second nozzle 340 slides along the corresponding fourth inclined slot 520, the second nozzle 340 can blow the material on the tine 300 at the rear side and the material between the tine 300 at the rear side and the current tine 300 to the side wall of the tank 110, and can flush the side of the tine 300 at the rear side and mounted with the first nozzle 310 in the blowing process, so as to reduce the probability of the material entering the installation gap of the first nozzle 310 and avoid affecting the normal operation of the first nozzle 310.

[0078] Meanwhile, since the third inclined slot 510 is symmetrical to the first inclined slot 410, the fourth inclined slot 520 is symmetrical to the second inclined slot 420, and the inclination of the third inclined slot 510 is greater than that of the fourth inclined slot 520, the time length of the second nozzle 340 blowing air to the direction close to the rotating shaft 131 is greater than the time length of the second nozzle 340 blowing air to the direction close to the side wall of the tank 110, so that the second nozzle 340 can reduce the amount of material blown to the side wall of the tank 110 and avoid affecting the normal operation of the present application.

[0079] Further, the second nozzle 340 is provided with a second positioning slot, the second elastic guide piece 350 comprises a second guide rod 351 and a second spring 352, one end of the second guide rod 351 is inserted into the second positioning slot, the other end of the second guide rod 351 is inserted into the second combined guide slot 500, the second spring 352 is located in the second positioning slot, and the two ends of the second spring 352 are fixedly connected with the bottom of the second positioning slot and the second guide rod 351 respectively, and the second elastic piece is configured to provide the second guide rod 351 with an elastic force always abutting against the corresponding second combined guide slot 500.

[0080] In the embodiment, when the first nozzle 310 sprays air, the first nozzle 310 is pushed by the reaction force thereof, and the tine 300 can be pushed to move along the length direction of the mounting rod 210 to approach the rake frame 200. Further, the second nozzle 340 is also moved to approach the rake frame 200, and the second nozzle 340 and the first nozzle 310 can be synchronously lifted.

[0081] In the embodiment, the second elastic guide 350 corresponding to the second nozzle 340 is arranged, even if the position of the first nozzle 310 relative to the rake frame 200 changes, or even if the orientation of the nozzle of the first nozzle 310 changes, the nozzle of the second nozzle 340 can always blow air on another tine 300 located behind the second nozzle 340, the cleaning of the mounting side of the tine 300 on which the first nozzle 310 is mounted can be ensured, the situation that the first nozzle 310 is stuck when the first nozzle 310 rotates can be avoided, the normal application of the first nozzle 310 can be ensured, and further, the normal implementation of the present application can be ensured. In some embodiments, the rotation groove 314 is arranged on each of the first nozzle 310 and the second nozzle 340, the first limiting shaft 320 and the second limiting shaft 321 are coaxially arranged with the rotation groove 314 on the corresponding nozzle, and the first limiting shaft 320 and the second limiting shaft 321 are respectively inserted into the corresponding rotation groove 314.

The two ends of the reset torsional spring 322 sleeved on the second limiting shaft 321 are fixedly connected with the side wall of the rotation groove 314 and the side wall of the second limiting shaft 321.

[0083] When the first nozzle 310 and the second nozzle 340 on the tine 300 rotate, the corresponding reset torsional spring 322 can be twisted, the reset torsional spring 322 can make the first nozzle 310 and the second nozzle 340 have a tendency to return to the initial state, when the first guide rod 331 and the second guide rod 351 slide to the initial position in the corresponding first combined guide groove 400 and second combined guide groove 500, the first nozzle 310 and the second nozzle 340 can be restored to the initial orientation, and the situation that the concentration of the material is greatly different when the present application outputs the material for multiple times due to the disordered orientation can be avoided.
