Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 13 As shown, the present invention provides a fertilizer discharging machine with adjustable fertilizer amount, comprising a fertilizer discharging shell 2, wherein a fertilizer discharging mechanism and a fertilizer discharging tongue 15 are installed inside the fertilizer discharging shell 2, and a first connecting end cover 4, a second connecting end cover 5 and a connecting tube 3 are sleeved on the fertilizer discharging mechanism, wherein the first connecting end cover 4 and the second connecting end cover 5 are respectively installed on the front and rear sides of the fertilizer discharging shell 2, and the end of the first connecting end cover 4 away from the fertilizer discharging shell 2 is connected to the connecting tube 3, and the fertilizer discharging mechanism is connected to a driving motor, and the fertilizer can be discharged along the fertilizer discharging tongue 15 through the fertilizer discharging tongue 15, while preventing the fertilizer from being directly discharged from the gap of the spiral blades; the fertilizer discharging mechanism can control the discharge amount of the fertilizer.

[0034] In this embodiment, the fertilizer discharge mechanism includes a fertilizer discharge shaft 7 and a fertilizer adjustment component. The fertilizer discharge shaft 7 is arranged in the fertilizer discharge housing 2. One end of the fertilizer discharge shaft 7 passes through the first connecting end cover 4 and the connecting tube 3, and the other end passes through the second connecting end cover 5. The fertilizer adjustment component is sleeved on the fertilizer discharge shaft 7. A first bearing 12 is provided at the connection between the fertilizer discharge shaft 7 and the connecting tube 3, and a third bearing 14 is provided at the connection between the fertilizer discharge shaft 7 and the second connecting end cover 5. A bearing cover 6 is sleeved on one end of the fertilizer discharge shaft 7 close to the third bearing 14, and the bearing cover 6 is connected to the second connecting end cover 5. The fertilizer discharge shaft 7 is provided with a spiral blade adapted to the fertilizer adjustment component; the fertilizer discharge shaft 7 discharges fertilizer through the spiral blade, and the spiral blade can push the fertilizer from one side of the fertilizer discharge tongue 15 to the other side.

[0035] In this embodiment, the fertilizer adjustment assembly includes a blocking wheel 8, a blocking wheel rear cover 9, a push rod 10 and a telescopic motor 11, one end of the push rod 10 is connected to a push ring, and the other end is connected to the output end of the telescopic motor 11, and the telescopic motor 11 is fixed in a telescopic motor box 16 on the inner wall of the connecting tube 3, the blocking wheel 8 and the push ring of the push rod 10 are sleeved on the fertilizer discharge shaft 7, and a threaded through groove is provided on the blocking wheel 8, and the threaded through groove is adapted to the spiral blade on the fertilizer discharge shaft 7, the pitch of the threaded through groove is equal to the pitch of the spiral blade, the groove width of the threaded through groove is slightly larger than the thickness of the spiral blade, and the inner diameter of the central axis hole of the blocking wheel 8 is slightly larger than the inner diameter of the spiral blade;

[0036] The push rod 10 is sleeved with a blocking wheel rear cover 9, and the blocking wheel 8 is provided with a first slide groove at one end close to the push rod 10, and the blocking wheel rear cover 9 is provided with a second slide groove at one end close to the push rod 10. The blocking wheel 8 is connected to the blocking wheel rear cover 9, and the first slide groove and the second slide groove are connected to form a mounting groove of the push ring, and the inner wall of the mounting groove abuts against the outer wall of the push ring, and the first slide groove and the second slide groove on both sides of the push ring are provided with second bearings 13;

[0037] The blocking wheel 8 cooperates with the spiral blade to adjust the amount of fertilizer in the spiral blade. The blocking wheel 8 can be pushed under the action of the telescopic motor 11 and the push rod 10. Pushing the blocking wheel 8 will cause the blocking wheel 8 to rotate and advance along the gap of the spiral blade to adjust the gap length of the spiral blade; the second bearing 13 arranged in the first slide groove on the left side of the push ring is sleeved on the fertilizer discharge shaft 7, which can prevent the blocking wheel 8 from driving the fertilizer discharge shaft 7 to rotate under the push of the telescopic motor, thereby avoiding the influence of the blocking wheel 8; the second bearing 13 arranged in the second slide groove on the right side of the push ring is sleeved on the push rod 10 and the fertilizer discharge shaft 7, which is used to prevent the blocking wheel 8 from driving the push rod 10 to rotate when the telescopic motor pushes it.

[0038] In this embodiment, Figure 4 The push ring is also provided with an annular baffle, the outer wall of which abuts against the inner wall of the mounting groove, and the inner wall of which abuts against the second bearings 13 on both sides of the push ring, so that the push ring part of the push rod 10 is stuck between the mounting groove and the two second bearings 13, avoiding direct contact between the push ring and the fertilizer discharge shaft 7.

[0039] In this embodiment, a receiving plate 2.1 is provided at the top of the fertilizer discharge shell 2, and the receiving plate 2.1 is connected to the fertilizer collecting box 1. Two fixing plates 2.3 are symmetrically provided on the side of the fertilizer discharge shell 2. A plurality of fixing holes are provided on the fixing plate 2.3, and the fertilizer discharge shell 2 is fixed through the fixing holes. A unilaterally inclined feed port 2.2 is also provided at the top of the fertilizer discharge shell 2, and a discharge port 2.4 is provided at the bottom of the fertilizer discharge shell 2; the unilaterally inclined feed port prevents the fertilizer from sliding clockwise along the spiral blades when the fertilizer machine is not working.

[0040] In this embodiment, the first bearing 12 and the third bearing 14 are both ball bearings.

[0041] In this embodiment, the second bearing 13 is a tapered roller bearing.

[0042] Working principle: When discharging fertilizer, the driving motor is connected to the part of the fertilizer discharging shaft 7 extending out of the bearing cover 6 through a coupling. The outer groove wheel rotates counterclockwise, and the fertilizer fills the gap between the spiral blades under the action of gravity and moves with the blades. Figure 5 The end of the right side of the fat discharge tongue 15 is finally discharged from the outlet at the lower end.

[0043] The fertilizer feed port 2.2 is designed with one side tilted, so that the fertilizer will not slide clockwise along the spiral blade when the fertilizer machine is not working; the fertilizer tongue 15 blocks the fertilizer from sliding directly counterclockwise along the spiral blade; the outer shell near the end of the fertilizer tongue 15 protrudes outward, so that the fertilizer will not be blocked when passing through here. Therefore, only when the fertilizer machine is working normally can the fertilizer be discharged smoothly without leakage and blockage. The threaded groove on the blocking wheel 8 and the spiral of the spiral blade make the fertilizer discharge of the fertilizer machine more uniform. At the same time, when the amount of fertilizer is adjusted by the telescopic motor 11, the adjustment accuracy of the telescopic motor 11 will be higher than the accuracy of manual adjustment, and the fertilizer discharge effect of the fertilizer machine will be better.

[0044] After the blocking wheel 8 is screwed into the spiral blade, the gap between the blades is occupied by the blocking wheel 8, and the amount of fertilizer that can be accommodated is reduced, thereby reducing the amount of fertilizer discharged in a single turn. Since the pitch of the spiral blade is large, the blocking wheel 8 can be screwed in by directly applying axial force to it. Therefore, a push rod 10 that can move linearly is used to push the movement of the blocking wheel 8 to adjust the amount of fertilizer discharged in a single turn. In order to obtain smoother adjustment performance, two second bearings 13 of appropriate size, that is, tapered roller bearings, are installed at the rear end of the blocking wheel 8. The bearing can both withstand the axial force of the push rod 10 and reduce the circumferential friction caused by the circular motion between the push rod 10 and the blocking wheel 8, so that the push rod 10 will not hinder the fertilizer discharge of the fertilizer machine whether it is stationary or pushed and pulled back and forth.

[0045] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
