[0011] The drive unit includes a drive motor, a drive shaft, and several synchronous pulley mechanisms; the drive motor drives the drive shaft to rotate; the rotating shafts of the two material distribution mechanisms are respectively connected to the drive shaft through the synchronous pulley mechanisms; when the drive shaft rotates, it drives the synchronous pulley mechanisms to rotate the rotating shaft.

[0012] The speed regulating mechanism includes several synchronous belt pulley mechanisms with different transmission ratios and a linkage; the linkage is used to connect or disconnect the drive shaft and the synchronous belt pulley mechanisms with different transmission ratios respectively.

[0013] The synchronous belt pulley mechanism includes a support base, a first synchronous pulley, a synchronous belt, and a second synchronous pulley.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] like Figure 1 , 5 As shown in Figure 6, a dynamic fertilizer mixing device with a soil conditioner quantitative mixing mechanism includes a mixing tank 1, two feeding tanks 2, a drive unit, and a speed regulating mechanism. The mixing tank 1 is hollow inside and equipped with a stirrer for mixing the soil conditioner and fertilizer introduced into the mixing tank 1. A discharge port 101 that can be opened and closed is provided at the bottom of the mixing tank 1. When the soil conditioner and fertilizer are mixed, the discharge port 101 is closed. After the mixing is completed, the discharge port 101 is opened so that the mixed materials are discharged from the discharge port 101.

[0032] Specifically, such as Figure 5 As shown, a discharge pipe extends downward from the bottom discharge port 101 of the mixing tank 1, and a pair of rotating discharge gates 102 are provided at the discharge port 101. One end of a hydraulic rod 103 is hinged to the bottom of the discharge gate 102, and the other end of the hydraulic rod 103 is hinged to the side wall of the discharge pipe. When the hydraulic rod 103 extends, the discharge ports close when the two discharge gates rotate to the same level. When the hydraulic rod 103 shortens, the two discharge gates rotate downward to a certain angle, and the discharge ports open.

[0033] It should be noted that the agitator is existing technology, comprising a stirring motor 104, a stirring shaft 105, and a stirring head 106. The stirring motor 104 is located at the top inner side of the mixing chamber 1, and the stirring head 106 is connected to the stirring motor 104 via the stirring shaft 105. Multiple blades on the stirring head 106 mix the materials. A sealing cover is provided on the outside of the stirring motor to seal and protect it, preventing the materials from contacting the motor. Mixing materials using an agitator is a common mixing method used by those skilled in the art and is not an improvement in this embodiment; therefore, it will not be described in detail here.

[0034] Two feeding boxes 2 are respectively located on the top sides of the mixing box 1, and are used for distributing soil conditioner and fertilizer respectively. A feeding port is provided on one side of the feeding box 2, and a feeding hopper 201 is provided outside the feeding port for easy pouring. Soil conditioner or fertilizer is poured into the feeding hopper 201 and enters the feeding box 2 through the feeding port. A distributing port 202 is provided at the bottom of the feeding box 2 and communicates with the inside of the mixing box 1. The material entering the feeding box 2 enters the mixing box 1 through the distributing port 202. In order to make the speed at which the material enters the mixing box 1 uniform and adjustable, a distributing mechanism is provided inside the feeding box 2 to feed the material into the mixing box 1 at a certain speed.

[0035] The drive unit is connected to the material distribution mechanism of the two feeding boxes 2 respectively, and is used to provide power to the material distribution mechanism and drive the material distribution mechanism to feed materials into the mixing box 1;

[0036] To further adjust the mixing ratio of soil conditioner and fertilizer, the speed at which the material is fed by the dispensing mechanism is changed. Therefore, a speed regulating mechanism is connected to the dispensing mechanism of one of the feeding boxes 2. Preferably, the speed regulating mechanism is connected to the feeding box 2 that dispenses soil conditioner. By adjusting the speed at which the dispensing mechanism of the feeding box 2 dispenses soil conditioner, the mixing ratio of soil conditioner and fertilizer is changed.

[0037] like Figure 6 As shown, in order to achieve a uniform material feeding speed by the material distribution mechanism, the material fed into the feeding box 2 is first separated into equal portions, and then these portions are fed into the mixing box 1 in sequence, thus achieving a uniform feeding speed.

[0038] In one embodiment, the material distribution mechanism includes a rotating shaft, a secondary shaft, a belt 206, and several material distribution plates 207 connected to the drive unit. The rotating shaft and the secondary shaft are parallel to each other and rotatably disposed inside the feed box 2, with the rotating shaft and the secondary shaft arranged vertically and vertically respectively. The belt 206 is wound around the rotating shaft and the secondary shaft. When the rotating shaft is driven to rotate by the drive unit, it drives the belt 206 to rotate. Several material distribution plates 207 are equidistantly wound around the outside of the belt 206. The material distribution plates 207 are in contact with the inner sidewall of the feed box 2, and adjacent material distribution plates 207 form a compartment with the inner sidewall of the feed box 2. When the material is put into the feed box 2, it is sequentially filled into multiple compartments. When the belt 206 rotates, the multiple compartments rotate accordingly, so that the compartments are connected to the material distribution port 202 at the bottom of the feed box 2, so that the material in the compartments falls into the mixing box 1 through the material distribution port 202.

[0039] In another embodiment, in order to avoid the mixing ratio being out of balance due to slippage or other factors during power transmission, a synchronization groove is wound around the side wall of the rotating shaft and the secondary shaft, and a synchronization tooth is wound around the inner side wall of the belt 206. Through the meshing of the synchronization groove and the synchronization tooth, the slippage phenomenon that is easy to occur during the transmission of power by the belt 206 is avoided.

[0040] like Figure 1As shown, the drive unit needs to be able to drive the dispensing mechanisms of the two feed boxes 2 to operate separately. One power source is used. Since a more precise mixing ratio of materials is required, a synchronous drive structure is preferred for power transmission to reduce the mixing ratio imbalance caused by slippage or other factors during power transmission. To better distinguish between the two feed boxes 2, the rotating shaft in the feed box 2 that conveys fertilizer is called the first rotating shaft, and the rotating shaft in the feed box 2 that conveys soil conditioner is called the second rotating shaft. When adjusting the mixing ratio, the rotation speed of the first rotating shaft is kept constant, and the rotation speed of the second rotating shaft is changed.

[0041] In one embodiment, the drive unit includes a drive motor 301, a drive shaft 304, and a plurality of synchronous pulley mechanisms 205; the use of a synchronous belt 2053 for power transmission can avoid slippage during transmission by the belt 206; the drive motor 301 is located on the top of the mixing box 1, and the drive shaft 304 is driven to rotate by the drive motor 301, so that the drive shaft 304 is parallel to the first rotating shaft and the second rotating shaft respectively;

[0042] The synchronous belt pulley mechanism 205 includes a first synchronous pulley 2052, a synchronous belt 2053, and a second synchronous pulley 2054. The first synchronous pulley 2052 is connected to the drive shaft 304 and rotates synchronously with the drive shaft 304 to provide power. The second synchronous pulley 2054 is connected to a first rotating shaft and a second rotating shaft respectively, so that the first rotating shaft and the second rotating shaft can rotate with the second synchronous pulley 2054. The synchronous belt 2053 is wound around the first synchronous pulley 2052 and the second synchronous pulley 2054, linking the first synchronous pulley 2052 and the second synchronous pulley 2054 together. The drive shaft 304 drives the first synchronous pulley 2052 to rotate, and the synchronous belt 2053 transmits power to the second synchronous pulley 2054, so that the second synchronous pulley 2054 drives the first rotating shaft and the second rotating shaft to rotate.

[0043] like Figure 3 As shown, in one embodiment, since it is not necessary to change the rotational speed of the first shaft, a set of synchronous belt pulley mechanisms with a fixed transmission ratio is used and installed on the drive shaft 304 and the first shaft. When adjusting the speed of soil conditioner application, it is necessary to change the rotational speed of the second shaft. Therefore, a set of synchronous belt pulley mechanisms with a variable transmission ratio is used and installed on the drive shaft 304 and the second shaft respectively. The set of synchronous belt pulley mechanisms with a variable transmission ratio includes multiple sets of synchronous belt pulley mechanisms with different transmission ratios. By switching to synchronous belt pulley mechanisms with different transmission ratios, the drive shaft 304 and the second shaft are linked, thereby changing the rotational speed of the second shaft.

[0044] The speed regulating mechanism is a linkage used to connect or disconnect the drive shaft 304 and the synchronous belt pulley mechanism 205 with different transmission ratios. When the drive shaft 304 rotates, it drives the first and second rotating shafts to rotate simultaneously through the synchronous belt pulley mechanisms connected to the first and second rotating shafts respectively. When it is necessary to change the mixing ratio, the linkage is used to switch to the synchronous belt pulley mechanism with the required transmission ratio to link the second rotating shaft and the drive shaft, so that the speed of soil conditioner application changes while the fertilizer application speed remains unchanged, thereby changing the mixing ratio of soil conditioner and fertilizer.

[0045] The first synchronous pulley 2052 in the variable transmission ratio synchronous belt pulley mechanism has a through hole at its center position and is sleeved on the drive shaft 304. There is a gap between the inner wall of the through hole and the drive shaft 304. When the first synchronous pulley 2052 is not connected to the drive shaft 304, it avoids the first synchronous pulley 2052 from contacting the drive shaft 304 and causing wear.

[0046] In order to keep the through hole and the axis of the drive shaft 304 coincident, a support base 2051 is provided on the top of the mixing box 1, and the first synchronous wheel 2052 is rotatably mounted on the support base 2051.

[0047] like Figure 3 and 4 As shown, the linkage is a synchronous sleeve 305, which is sleeved and slidably mounted on the drive shaft 304. A limiting mechanism is provided at the contact point between the synchronous sleeve 305 and the drive shaft 304, so that the synchronous sleeve 305 and the drive shaft 304 can rotate synchronously and ensure that the synchronous sleeve 305 can slide along the axis of the drive shaft 304. An external retaining tooth 3051 is provided on the outer wall of the synchronous sleeve 305 near the end of the first synchronous pulley. An internal retaining tooth 2055 is provided on the inner wall of the through hole to mesh with the external retaining tooth 3051. The synchronous sleeve 305 slides along the drive shaft 304. This causes the outer locking tooth 3051 to move to the through hole of the first synchronous pulley 2052, so that the outer locking tooth 3051 meshes with the inner locking tooth 2055 at the through hole; when the synchronous sleeve 305 rotates with the drive shaft 304, the synchronous sleeve 305 rotates synchronously with the first synchronous pulley 2052; when the synchronous sleeve 305 slides along the drive shaft 304, the outer locking tooth 3051 moves to the through holes of different first synchronous pulleys 2052, so that the synchronous belt pulley mechanisms with different transmission ratios of the drive shaft 304 are connected, thereby changing the application speed of the soil conditioner.

[0048] To drive the synchronizing sleeve 305 to move along the drive shaft 304, a sliding mechanism is also provided, such as... Figure 4As shown, it includes a mounting base 3071, a lead screw 3072, a sliding seat 3073, and a paddle 3074; and an annular groove 3052 is provided around the outer side wall of the synchronizing sleeve 305 away from the outer retaining tooth 3051; there are two mounting bases 3071, which are respectively located on the top of the mixing box 1, next to the drive shaft 304; the two ends of the lead screw 3072 are respectively rotatably mounted on the mounting base 3071, and the lead screw 3072 is parallel to the drive shaft 304; the sliding seat 3073 is fitted onto the lead screw. The sliding seat 3072 is mounted on the top of the mixing box 1, and the bottom of the sliding seat 3073 is attached to the top of the mixing box 1, thereby restricting the rotation of the sliding seat 3073 around the axis of the lead screw 3072. The sliding seat 3073 is provided with a through screw hole, and the lead screw 3072 is fitted into the screw hole. A motor is provided inside the mounting base 3071 on one side and is connected to one end of the lead screw 3072 to drive the lead screw 3072 to rotate. The rotation of the lead screw 3072 can drive the sliding seat 3073 to move along the lead screw 3072. The paddle 3074 is connected at one end to the sliding seat 3073, allowing it to move with the sliding seat 3073. The other end of the paddle 3074 is provided with a retaining ring and is rotatably disposed in the annular groove 3052. When the paddle 3074 moves with the sliding seat 3073, it can push the synchronous sleeve 305 to move along the drive shaft 304, thereby causing the outer retaining tooth 3051 to mesh with different inner retaining teeth 2055. This allows the drive shaft 304 to be connected to the rotating shaft through different synchronous pulley mechanisms 205, changing the mixing ratio. Since it is necessary to ensure that when the synchronous sleeve moves, the outer retaining tooth 3051 can move to the through hole of the first synchronous pulley 2052 located on the outermost two sides of the variable transmission ratio synchronous pulley mechanism group, and to ensure that the paddle 3074 does not contact the first synchronous pulley and cause interference when it moves with the sliding seat 3073, the length of the synchronous sleeve is greater than the overall length of the variable transmission ratio synchronous pulley mechanism group on the drive shaft.

[0049] To reduce mechanical wear between the inner clamping tooth 2055 and the outer clamping tooth 3051 during gear shifting, it is necessary to be able to cut off the power transmission between the drive motor 301 and the drive shaft 304 during gear shifting. Figure 2As shown, a clutch 302, preferably a ZF clutch 302, is also provided between the drive motor 301 and the drive shaft 304. This clutch 302 connects the flywheel of the clutch 302 to the output shaft of the drive motor 301, and one end of the drive shaft 304 is connected to the driven plate of the clutch 302. A clutch engagement / disengagement mechanism is provided, including a pressure ring 3031, an abutment joint 3032, a rotating arm 3033, and a hinge seat 3034. The pressure ring 3031 is sleeved on the drive shaft 304 and located next to the diaphragm spring of the clutch 302. The hinge seat 3034 is located at the top of the mixing chamber 1, next to the clutch 302, and in the middle of the rotating arm 3033. Hinged on the hinge seat 3034, one end of the rotating arm 3033 is the abutment 3032, which contacts the side of the pressure ring 3031 away from the clutch 302. By rotating the rotating arm 3033, the abutment 3032 pushes the pressure ring 3031 closer to and against the clutch 302, thereby causing the pressure ring 3031 to press the diaphragm spring and causing the pressure plate inside the clutch 302 to separate from the friction plate, thereby cutting off the power transmission between the drive motor 301 and the drive shaft 304. This facilitates the pushing of the synchronous sleeve 305, so that the drive shaft 304 is connected to the rotating shaft through different synchronous pulley mechanisms 205, changing the mixing ratio.

[0050] The working principle of this embodiment is as follows:

[0051] This utility model discloses a dynamic fertilizer mixing device with a soil conditioner quantitative mixing mechanism. First, the drive motor 301 operates and pushes the synchronous sleeve 305 to move along the drive shaft 304. According to the required mixing ratio, the outer clamping tooth 3051 meshes with the required inner clamping tooth 2055, so that the distributing mechanism in the two side feed boxes 2 operates at a specific speed. Then, the soil conditioner and fertilizer are poured into the feed hoppers 201 of the two side feed boxes 2 respectively, and they are driven by the belt 206, so that the soil conditioner and fertilizer are fed into the mixing box 1 at a specific speed. After the agitator mixes the soil conditioner and fertilizer evenly, the discharge door 102 at the bottom of the mixing box 1 is opened to discharge the mixture.

[0052] When speed adjustment is required, rotating the rotating arm 3033 causes the abutment 3032 to push the pressure ring 3031 closer to and engage with the clutch 302. The pressure ring 3031 presses the diaphragm spring, causing the pressure plate inside the clutch 302 to separate from the friction plate, cutting off the power transmission between the drive motor 301 and the drive shaft 304. Then, the synchronous sleeve 305 is pushed, causing the outer clamping tooth 3051 to mesh with the required inner clamping tooth 2055. Then, the rotating arm 3033 returns to its original position, and the drive shaft receives power to continue rotating. At this time, the soil conditioner is added at a different speed, which in turn changes the mixing ratio.

[0053] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
