[0019] The present invention will be further explained below in conjunction with specific implementation schemes, but the present invention is not limited thereto.

[0020] like Figure 1-6As shown, the present invention provides a novel fertilizer discharger, characterized in that it includes: a left shell 1, a right shell 2, a fertilizer discharge brush 3, a fertilizer blocking brush 4, a fertilizer scraping steel sheet 5, a transmission shaft 6, a groove wheel pressure seat 7, a lead screw 8, a blocking wheel 9, a plurality of butterfly bolts 10, a blocking wheel seat 11, a cylindrical pin 12, a groove wheel 13, a groove wheel steel sheet 14, a groove wheel seat 15 and the retaining ring 16. The left shell 1 and the right shell 2 are installed in cooperation with each other on the left and right sides, and a fertilizer inlet and a fertilizer outlet are respectively provided at the upper and lower ends. The transmission shaft 6 passes through the side surfaces of the left shell 1 and the right shell 2, and a middle circular hole for carrying the transmission shaft 6 is processed. The transmission shaft 6 extends out of the left shell 1 and is connected to an external driving device. The groove wheel 13 is sleeved on the transmission shaft 6 , and is located in the left shell 1 and the right shell 2, the blocking wheel 9 passes through the middle circular hole of the right shell 2, and is sleeved on the outside of the groove wheel 13, the blocking wheel seat 11 is sleeved on the blocking wheel 9, and is connected to the outer surface of the right shell 2 through a plurality of screws, the lead screw 8 passes through the center of the blocking wheel 9, and is connected to the inner thread groove at the center of the groove wheel 13 through the threaded groove on the surface of the lead screw 8, the retaining ring 16 is sleeved in the retaining ring groove on the inner side of the lead screw 8 to limit the end face of the blocking wheel 9, a plurality of butterfly bolts 10 are located at one end of the lead screw 8 to tighten the lead screw 8 and the blocking wheel 9, the fertilizer discharge brush 3 and the fertilizer blocking brush 4 are both located in the left shell 1 and the right shell The upper end of the fertilizer discharge brush 3 and the lower end of the fertilizer blocking brush 4 are respectively overlapped on the circumferential surface of the groove wheel 13 and the blocking wheel 9 to block the fertilizer. The fertilizer scraping steel sheet 5 is located at the lower end of the left shell body 1 and the right shell body 2, and is placed at a cutting angle with the circumferential surface of the blocking wheel 9. The groove wheel steel sheet 14 is located between the groove wheel seat 15 and the groove wheel 13. The cylindrical pin 12 passes through the circular mounting hole on the transmission shaft 6 and penetrates into the groove wheel 13. The groove wheel pressure seat 7, the groove wheel steel sheet 14 and the groove wheel seat 15 are sequentially mounted on the groove wheel 13. The groove wheel pressure seat 7 is installed on the end face of the groove wheel 13 and is connected to the outer surface of the left shell body 1 through a number of screws. The groove wheel 13 is connected, and the groove wheel pressing seat 7 can rotate, but the groove wheel pressing seat 7 does not rotate. When using this device, the fertilizer inlet at the upper end after the left shell body 1 and the right shell body 2 are combined with each other is convenient for the fertilizer to flow in, and the fertilizer outlet at the lower end is convenient for the fertilizer to be discharged downward through the internal transmission. The groove wheel 13 located between the left shell body 1 and the right shell body 2 is convenient for horizontal synchronous radial rotation under the drive of the transmission shaft 6. Due to the shape of the groove wheel 13, it is convenient to carry the fertilizer in each groove and to transmit the fertilizer downward in weight. The end of the transmission shaft 6 extending out of the left shell body 1 is connected to the external driving device, that is, the driving end of the driving motor, so that it is convenient to rotate under the rotation of the external driving motor, thereby rotating the groove wheel 13.Combined with the shape of the groove on the circumferential surface of the groove wheel 13, the fertilizer is continuously transmitted downward, wherein the blocking wheel 9 located on the outer side of the groove wheel 13 is convenient for fitting on the groove wheel 13. The degree of fitting on the groove wheel 13 is adjusted according to the amount of fertilizer required. If the groove of the groove wheel 13 is exposed for a long time, more fertilizer will be transmitted each time. If the groove of the groove wheel 13 is exposed for a short time, less fertilizer will be transmitted each time. The horizontal adjustment position of the blocking wheel 9 is determined by manually twisting the lead screw 8 through the screwing position of the threaded groove on the surface of the lead screw 8 and the internal threaded groove at the center of the groove wheel 13. After the position is fixed, several butterfly bolts 10 located on the outer side of the lead screw 8 are twisted to fix the lead screw 8 so that the overall position does not move. Several butterfly bolts 10 are passed through There are usually three of them, and the triangular fixing effect is good. Because it is butterfly-shaped, it is convenient to hold when manually twisting. The retaining ring 16 located between the screw 8 and the blocking wheel 9 is convenient for forming axial limit between the screw 8 and the blocking wheel 9 and enabling radial rotation. When discharging fertilizer, the fertilizer discharge brush 3 located between the left shell 1 and the right shell 2 is overlapped on the outer surface of the blocking wheel 9, which is convenient for properly blocking the position where the fertilizer is not transferred downward through the groove wheel 13 to prevent the fertilizer from going down directly, and it is also convenient to properly clean the outer surface of the blocking wheel 9 to prevent fertilizer accumulation. The fertilizer blocking brush 4 is used to properly block the fertilizer discharged from the lower row to prevent the fertilizer from flowing back into the gap between the blocking wheel 9 and the shell, causing blockage. The fertilizer scraping steel sheet 5 which is in the right shell body 2 and overlaps the circumferential surface of the other end of the blocking wheel 9 is convenient for scraping and cleaning the fertilizer accumulated on the surface of the blocking wheel 9. The groove wheel pressure seat 7 is mounted on one end of the groove wheel 13 and is connected to the outer surface of the left shell body 1 through a number of screws, which is convenient for fixing one end of the groove wheel 13. However, the groove wheel 13 can be rotated in the groove wheel pressure seat 7, which is convenient for rotating with the rotation of the transmission shaft 6. The blocking wheel seat 11 is mounted on the blocking wheel 9 and is connected to the outer surface of the right shell body 2 through a number of screws. The blocking wheel seat 11 supports the blocking wheel 9 and prevents the blocking wheel 9 and the right shell body 2 from wearing. The cylindrical pin 12 penetrates the transmission shaft 6 and penetrates into the groove wheel 13, which is convenient for fixing by penetrating the cylindrical pin 12. The groove wheel 13 rotates with the rotation of the transmission shaft 6 to form a radial linkage. At the same time, the inner groove of the blocking wheel 9 cooperates with the outer groove of the groove wheel 13 to form a radial linkage. The circumferential surface of the blocking wheel 9 located inside the shell and in direct contact with the fertilizer is fully cleaned by the fertilizer scraping steel sheet 5 to ensure the continuous and uninterrupted operation of the fertilizer discharger. The external thread of the lead screw 8 is installed in cooperation with the internal thread of the groove wheel 13. The rotating end face of the lead screw 8 is provided with a positioning screw hole. The lead screw 8 and the blocking wheel 9 are tightened by a number of butterfly bolts 10 to prevent the lead screw 8 and the blocking wheel 9 from axial displacement. The groove wheel seat 15, the groove wheel steel sheet 14, and the groove wheel 13 are installed in the middle hole of the left shell 1 in sequence. The groove wheel steel sheet 14 serves as a friction medium on the contact surface between the groove wheel seat 15 and the groove wheel 13, which effectively prolongs the service life.The transmission shaft 6 is installed with a cylindrical pin 12 and inserted into the middle hole of the groove wheel 13 to form a linkage fit. Through the above linkage fit and adjusting the exposed length of the fertilizer discharge groove of the groove wheel 13 in the blocking wheel 9, the amount of fertilizer can be controlled.

[0021] Attached to the instruction manual Figure 1-6 It can be seen that the length of the inner groove of the blocking wheel 9 matches the length of the outer groove of the groove wheel 13. Since the lengths match, it can be completely blocked or not blocked at all, and the adjustment range is relatively large.

[0022] Attached to the instruction manual Figure 1-6 It can be seen that the left shell 1 and the right shell 2 are both shells formed by injection molding, which are easy to mold, install, disassemble and maintain, and are suitable for the installation of various internal parts.

[0023] Attached to the instruction manual Figure 1-6 It can be seen that the fertilizer discharge brush 3 and the fertilizer retaining brush 4 are both composed of a base plate and brush wires. The brush wire parts of the fertilizer discharge brush 3 and the fertilizer retaining brush 4 are in a compacted state with the groove wheel 13 and the blocking wheel 9. Each base plate is connected to the inner surface of the left shell 1 or the right shell 2 by screws, which is convenient for disassembly and installation. Due to the compacted state, the shielding effect is better. The connection method between the base plate and the brush wire includes but is not limited to direct clamping or locking connection through connecting nails, etc., and it only needs to be fixed as shown in the figure.

[0024] Attached to the instruction manual Figure 1-6 It can be seen that the groove is provided in the sheave pressing seat 7, and the groove squeezes and fixes the sheave 13, the sheave steel sheet 14 and the sheave seat 15. The sheave pressing seat 7 is placed opposite to the sheave seat 15 and is respectively located on the two side end surfaces of the sheave 13, so as to fix the sheave 13.

[0025] Attached to the instruction manual Figure 1-6 It can be seen that the groove wheel pressure seat 7 is connected to the outer surface of the left shell body 1 through a number of screws, the inner groove of the groove wheel pressure seat 7 is pressed on the end face of the groove wheel 13, and the screws pass through the screw holes of the groove wheel pressure seat 7 and are fastened to the three screw holes on the circumference of the middle mounting hole of the left shell body 1, which is convenient for good fixation and disassembly and installation.

[0026] Figure 6 This is a diagram of the working principle of the components in the side view cross-section diagram with the fertilizer transfer path. The circles represent the fertilizer, and the position of the circles is only used to indicate its transfer path.

[0027] The length of the inner groove of the blocking wheel 9 and the length of the outer groove of the groove wheel 13 can match each other, but are not limited to this length design. In principle, the inner groove of the blocking wheel 9 is not smaller than the outer groove of the groove wheel 13, so that the blocking wheel 9 can completely block the groove wheel 13.
