Description

Technical Field

[0001] The utility model relates to a seeder, in particular to a material discharging regulating mechanism of the seeder. Background Art

[0002] The seeder is a mechanism that discharges seeds at a set flow rate through the rotation of the seeding wheel. The seeder feeding adjustment mechanism can put a certain amount of seeds into the seeding wheel. The conventional solution is to set protrusions and grooves on the slideway and the slide plate. When the slide plate and the slideway move relative to each other, the protrusions and grooves will be worn, which will not play a positioning role on the slide plate and cannot adjust the size of the feed opening.

[0003] In summary, how to adjust the size of the feed inlet has become an urgent problem that researchers in this field need to solve. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to adjust the size of the feed opening;

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] The utility model discloses a feed adjustment mechanism for a seed drill, comprising: a housing; a slide slot, which is obliquely arranged on the inner wall of the housing; a slide plate, whose two sides are slidably arranged in the slide slot; a plurality of limit slots, which are arranged at the slide slot along the length direction of the slide slot; a lever, which is arranged on the slide plate and is suitable for moving along the width direction of the slide plate; the lever is laterally shifted to place the lever in the corresponding limit slot, so that a feed inlet is formed between the end of the slide plate and the housing;

[0007] In this solution, the slide plate is arranged obliquely and cooperates with the slide groove, and the gap between the end of the slide plate and the shell forms a feed port; by horizontally shifting the lever, the lever is placed in the corresponding limit groove, so that the relative position between the slide plate and the slide groove is fixed, and the size of the feed port is also fixed, thereby realizing the adjustment of the size of the feed port.

[0008] How to realize the lateral movement of the lever, the utility model adopts a method of opening a waist hole on the slide board along the width direction of the slide board; the small diameter section of the lever passes through the waist hole, and the large diameter section of the lever abuts against the surface of the slide board;

[0009] In this solution, the waist hole is provided so that the lever can move along the width direction of the skateboard, and the lever is designed into a small diameter section and a large diameter section, which can limit the lever from escaping from the waist hole in one direction.

[0010] In order to illustrate the specific structure of the limiting groove, the limiting groove adopted in the utility model includes: a first groove and a second groove which are connected to each other; wherein the first groove is opened along the width direction of the slide groove, and has an entrance with the side of the slide groove; the second groove is opened along the length direction of the slide groove;

[0011] The first groove and the second groove form an L-shaped structure, and the lever enters the second groove along the first groove. In this way, when the skateboard is subjected to the force of its own weight, the lever cannot be separated from the second groove, thereby ensuring the stability of the connection between the skateboard and the slide groove.

[0012] In order to be able to move the lever, the utility model adopts an operating chamber for an operator to hold and move the lever, which is provided in the housing and below the slide slot;

[0013] In this way, the operator can put his hand into the operating cavity to operate the lever;

[0014] In this solution, when the lever is moved to the uppermost limit slot, the feed inlet is the largest and the material flow rate entering the shell is the largest; when the lever is moved to the lowermost limit slot, the feed inlet is the smallest, the shell is in a closed state, and no material is fed.

[0015] The beneficial effects of the utility model are as follows: the utility model is a feed discharge adjustment mechanism for a seed drill, the slide plate is obliquely arranged and cooperates with the slide groove, the gap between the end of the slide plate and the shell forms a feed inlet; by horizontally shifting the lever, the lever is placed in the corresponding limit groove, so that the relative position between the slide plate and the slide groove is fixed, the size of the feed inlet is also fixed, and the size of the feed inlet is adjusted.

[0021] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0022] like Figure 1-2 As shown, the utility model is a feed adjustment mechanism for a seed drill, comprising: a housing 1; a chute 2, which is obliquely arranged on the inner wall side of the housing 1; a slide plate 3, both sides of which are slidably arranged in the chute 2; a plurality of limit grooves 4, which are opened at the chute 2 along the length direction of the chute 2; a lever 5, which is arranged on the slide plate 3 and is suitable for moving along the width direction of the slide plate 3; the lever 5 is laterally moved to place the lever 5 in the corresponding limit groove 4, and a feed inlet 6 is formed between the end of the slide plate 3 and the housing 1;

[0023] In this solution, the slide plate is arranged obliquely and cooperates with the slide groove, and the gap between the end of the slide plate and the shell forms a feed port; by horizontally shifting the lever, the lever is placed in the corresponding limit groove, so that the relative position between the slide plate and the slide groove is fixed, and the size of the feed port is also fixed, thereby realizing the adjustment of the size of the feed port.

[0024] like Figure 3 As shown, how to realize the lateral movement of the lever, the utility model adopts a waist hole 31 opened on the slide plate 3 along the width direction of the slide plate; the small diameter section 51 of the lever 5 passes through the waist hole 31, and the large diameter section 52 of the lever 5 abuts against the surface of the slide plate 3;

[0025] In this solution, the waist hole is provided so that the lever can move along the width direction of the skateboard, and the lever is designed into a small diameter section and a large diameter section, which can limit the lever from escaping from the waist hole in one direction.

[0026] like Figure 1-2 As shown, in order to illustrate the specific structure of the limit groove, the limit groove adopted by the utility model includes: a first groove 7 and a second groove 8 that are connected to each other; wherein the first groove 7 is opened along the width direction of the slide groove 2, and has an entrance with the side of the slide groove 2; the second groove 8 is opened along the length direction of the slide groove 2;

[0027] The first groove and the second groove form an L-shaped structure, and the lever enters the second groove along the first groove. In this way, when the skateboard is subjected to the force of its own weight, the lever cannot be separated from the second groove, thereby ensuring the stability of the connection between the skateboard and the slide groove.

[0028] like Figure 1 As shown, in order to be able to move the lever, the utility model adopts an operating chamber 9 for an operator to hold and move the lever 5, which is provided in the housing 1 and below the slide slot 3;

[0029] In this way, the operator can put his hand into the operating cavity to operate the lever;

[0030] In this solution, when the lever is moved to the uppermost limit slot, the feed inlet is the largest and the material flow rate entering the shell is the largest; when the lever is moved to the lowermost limit slot, the feed inlet is the smallest, the shell is in a closed state, and no material is fed.

[0031] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
