Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a seeding rate adjustment and compensation device. Background Technology

[0002] In existing technologies, seeders are used to automatically sow seeds in fields. The sowing structure includes a seed box fixedly connected to a frame, with several seeders fixedly connected to the lower side of the seed box. A motor drives a grooved wheel inside the seeder's housing to rotate, achieving automatic seed distribution. When the seeding rate needs adjustment, the motor speed is adjusted to control the grooved wheel speed, thereby adjusting the seeding rate. However, the motor alone cannot arbitrarily adjust the seeding rate to any desired parameter. But by adjusting the position of the grooved wheel, compensation can be made for the seeding rate adjustment achieved through motor speed control, thus expanding the seeding rate adjustment range. Therefore, a seeding rate adjustment compensation device is urgently needed to achieve seeding rate adjustment compensation. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] In view of the problems existing in the above and / or existing seeding technologies, this utility model is proposed.

[0005] Therefore, the problem that this utility model aims to solve is the limited range of seeding adjustment.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a seeding rate adjustment and compensation device, which includes a seeding box fixedly connected to a frame, a plurality of seeders connected to the lower side of the seeding box, and grooved wheels of the plurality of seeders connected by a drive shaft. The grooved wheels can slide along the axial direction of the drive shaft. A circular first adjustment shaft and a second adjustment shaft are fixedly connected to both ends of the grooved wheels, respectively. A manual adjustment and compensation component is connected to the seeding box. The manual adjustment and compensation component includes a sliding block slidably connected to the drive shaft. The sliding block is connected to the grooved wheel of one of the seeders at one end in the left-right direction. The grooved wheel can rotate relative to the sliding block. In the initial state, the section where the drive shaft and the grooved wheel are connected is not a complete circle, and the drive shafts on both sides of the grooved wheel are circular. The outer edge of the non-circular part exceeds the outer edge of the circular part.

[0007] Before operation, adjust the position of the grooved wheel according to the required precise seeding rate. This allows for precise adjustment of the seeding rate per revolution of the seeder's grooved wheel, serving as a seeding rate compensation for motor speed adjustment. During operation, move the sliding block, which in turn moves the grooved wheel. When the sliding block reaches the appropriate position, fix it relative to the frame to adjust the seeder's own seeding rate, further expanding the seeding rate adjustment range. This can be applied to seeding rate adjustment compensation operations.

[0008] As a preferred embodiment of the seeding rate adjustment and compensation device of this utility model, the manual adjustment and compensation component further includes a fixed bracket disposed above the sliding block and fixedly connected to the outside of the seed box. The fixed bracket has an arc-shaped sliding groove, and a swing bracket is movably connected to the sliding block. The upper part of the swing bracket is fixedly connected to a movable rod that can slide along the sliding groove.

[0009] In a preferred embodiment of the seeding rate adjustment and compensation device of this utility model, a fixed plate is fixedly connected to the seeding box between the fixed bracket and the sliding block, and a support shaft is fixedly connected to the fixed plate. The swing bracket is rotatably connected to the support shaft, and the axis of the arc surface where the upper and lower edges of the sliding groove are located is consistent with the axis of the support shaft.

[0010] As a preferred embodiment of the broadcast volume adjustment and compensation device of this utility model, it further includes a connecting bracket fixedly connected to the inner side of the frame. The connecting bracket includes a plurality of fixed rods arranged on the inner side of the frame. A fixed plate is fixed on the side of the fixed rods opposite to the sliding block. A plurality of first fixed holes are arranged on the fixed plate. A plurality of second fixed holes corresponding one-to-one with the first fixed holes are arranged on the sliding block.

[0011] As a preferred embodiment of the broadcast volume adjustment and compensation device of this utility model, the manual adjustment and compensation component further includes a first connecting sleeve fitted on the transmission shaft. One side of the first connecting sleeve is fixed to the end of the sliding block away from the inner side of the frame. The side of the first adjusting shaft away from the grooved wheel is disposed opposite to the sliding block. A first connecting ring is detachably connected to the side of the first adjusting shaft away from the grooved wheel. A circular first insertion groove is opened on the side of the first connecting ring opposite to the first adjusting shaft. A circular first insertion sleeve is detachably connected to the side of the first connecting sleeve away from the sliding block and inserted into the first connecting ring through the first insertion groove. The outer diameter of the first insertion sleeve is larger than the outer diameter of the first connecting sleeve.

[0012] In a preferred embodiment of the seeding rate adjustment and compensation device of this utility model, a second connecting sleeve is also fitted on the transmission shaft between the grooved wheels of two adjacent seeders. A second connecting ring is detachably connected to the side of the second adjusting shaft away from the grooved wheel. A circular second insertion groove is opened on the side of the second connecting ring opposite to the second adjusting shaft. An insertion part is fixed on one side of the second connecting sleeve. The insertion part is inserted into the second connecting ring through the second insertion groove. A second insertion sleeve is detachably connected to the other side of the second connecting ring. The outer circumference of the second insertion sleeve is circular. The second insertion sleeve is inserted into the corresponding second connecting ring through the corresponding second insertion groove.

[0013] As a preferred embodiment of the broadcast volume adjustment and compensation device of this utility model, the movable rod is threaded with a manual handle for easy operation.

[0014] The beneficial effects of this utility model are as follows: By manually operating the handle, the swing bracket is oscillating, which drives the sliding block to slide along the transmission shaft. The sliding block drives the grooved wheel inside the seeder, which is close to the sliding block, to move via the first connecting sleeve. This grooved wheel drives the next grooved wheel to move via the second connecting sleeve, and so on, thereby realizing the adjustment of the position of each grooved wheel and thus the adjustment of the seed discharge of the seeder itself. After the adjustment is completed, the fixing bolt is screwed into the second fixing hole and the first fixing hole, and the nut is screwed on the fixing bolt on the side of the fixing plate away from the sliding block so that the nut abuts against the fixing plate, thereby fixing the sliding block and the frame, that is, fixing the position of each grooved wheel, which is convenient to operate.

Detailed Implementation

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figure 1 This is the first embodiment of the present invention, which provides a seeding rate adjustment and compensation device. The seeding rate adjustment and compensation device includes a seed box 600 fixedly connected to a frame 100. A plurality of seeders 300 are connected to the lower side of the seed box 600. The grooved wheels 301 of the seeders 300 are connected via a drive shaft 500. The grooved wheels 301 can slide along the axial direction of the drive shaft 500. A circular first adjustment shaft 303 and a second adjustment shaft 302 are fixedly connected to both ends of the grooved wheels 301, respectively. A manual adjustment compensation component 200 is connected to the seed box 600 for manual adjustment. The compensation component 200 includes a sliding block 201 slidably connected to the drive shaft 500. The sliding block 201 is connected to a grooved wheel 301 of a seeder 300 at one end in the left-right direction. The grooved wheel 301 can rotate relative to the sliding block 201. In the initial state (the state where the seeder 300 has the largest seeding capacity, i.e., the state where the length of the grooved wheel 301 is the largest in the housing of the seeder 300), the section where the drive shaft 500 and the grooved wheel 301 are connected is not a complete circle. The drive shaft 500 on both sides of the grooved wheel 301 is circular, and the outer edge of the non-circular shape exceeds the outer edge of the circular shape.

[0032] Before operation, adjust the position of the grooved wheel 301 according to the required precise seeding amount, so as to accurately adjust the seeding amount of the seeder 300 itself per revolution of the grooved wheel 301. This serves as seeding amount compensation for the motor speed adjustment. During operation, move the sliding block 201, which drives the grooved wheel 301 to move. When the sliding block 201 moves to the appropriate position, fix the sliding block 201 relative to the frame 100 to realize the adjustment of the seeding amount of the seeder 300 itself. This can be applied to the compensation operation of seeding amount adjustment.

[0033] Example 2: Refer to Figure 2 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, it also includes a connecting bracket 400 fixedly connected to the inside of the frame 100. The connecting bracket 400 includes a plurality of fixing rods 401 arranged inside the frame 100. A fixing plate 402 is fixed to one side of the fixing rods 401 relative to the sliding block 201. A plurality of first fixing holes 402-1 are arranged on the fixing plate 402. A plurality of second fixing holes 201-1 corresponding one-to-one with the first fixing holes 402-1 are arranged on the sliding block 201.

[0035] Under normal use, the fixing bolts securely connect the sliding block 201 and the fixing plate 402 together. When a slight adjustment of the seeding amount is required, loosen the fixing nut, rotate the fixing bolt, adjust the rotation direction of the fixing bolt so that the fixing bolt moves away from the fixing plate 402 to a suitable position, stop rotating the fixing bolt, and then adjust the position of the sliding block 201. The sliding block 201 drives the grooved wheel 301 to move. When the sliding block 201 moves to a suitable position, stabilize the sliding block 201, screw in the fixing bolt so that the fixing bolt is screwed into the first fixing hole 402-1, and screw on the fixing nut so that the fixing nut is pressed against the side of the fixing plate 402 away from the sliding block 201, thereby fixing the sliding block 201 relative to the frame 100 and fixing the position of the grooved wheel 301.

[0036] Example 3: Reference Figure 1 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the manual adjustment compensation component 200 also includes a fixed bracket 203202 disposed above the sliding block 201 and fixedly connected to the outside of the seed box 600. The fixed bracket 203202 has an arc-shaped sliding groove 202-1. A swing bracket 204 is movably connected to the sliding block 201. A movable rod that can slide along the sliding groove 202-1 is fixedly connected to the upper part of the swing bracket 204. A fixed plate is fixedly connected to the seed box 600 between the fixed bracket 203202 and the sliding block 201. A support shaft is fixedly connected to the fixed plate. The swing bracket 204 is rotatably connected to the support shaft. The axis of the arc surface where the upper and lower edges of the sliding groove 202-1 are located is consistent with the axis of the support shaft. A manual handle 205 for easy operation is threaded onto the movable rod.

[0038] The fixed brackets 203202 above and below the sliding groove 202-1 are provided with scales (which are prior art and are not shown in the accompanying drawings of this application). By manually holding the crank handle 205, the swing bracket 204 is swung, and the swing bracket 204 drives the sliding block 201 to slide along the transmission shaft 500. When the swing bracket 204 swings to the appropriate scale position (that is, the grooved wheel 301 moves to the appropriate position, that is, the length of the grooved wheel 301 in the housing of the seeder 300 is adjusted to the appropriate length), the sliding block 201 is fixed.

[0039] Example 4: Reference Figures 4-10 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment and can further realize the synchronous movement of the sliding block 201 and the groove wheel 301.

[0040] Specifically, the manual adjustment compensation component 200 also includes a first connecting sleeve 206 fitted on the drive shaft 500. One side of the first connecting sleeve 206 is fixed to the end of the sliding block 201 away from the inner side of the frame 100. The side of the first adjusting shaft 303 away from the grooved wheel 301 is set opposite to the sliding block 201. A first connecting ring 207 is detachably connected to the side of the first adjusting shaft 303 away from the grooved wheel 301. A circular first insertion groove 207-2 is opened on the side of the first connecting ring 207 opposite to the first adjusting shaft 303. A plurality of first connecting holes 207-1 are arranged on the first connecting ring 207 outside the first insertion groove 207-2. A plurality of first connecting countersunk holes corresponding one-to-one with the first connecting holes 207-1 are arranged on the first adjusting shaft 303. A circular first insertion sleeve 210 is threadedly connected to the side of the first connecting sleeve 206 away from the sliding block 201 and inserted into the first connecting ring 207 through the first insertion groove 207-2.

[0041] The connection between the first connecting sleeve 206, the first connecting ring 207 and the groove wheel 301 does not affect the rotation of the groove wheel 301 during sowing.

[0042] Specifically, a second connecting sleeve 209 is fitted onto the drive shaft 500 between the grooved wheels 301 of two adjacent seeders 300. A second connecting ring 208 is detachably connected to the side of the second adjusting shaft 302 away from the grooved wheels 301. Several second connecting holes 208-1 are arranged on the second connecting ring 208. Several second connecting countersunk holes corresponding one-to-one with the second connecting holes 208-1 are arranged on the second adjusting shaft 302. A circular second insertion countersunk groove 208-2 is opened on the side of the second connecting ring 208 opposite to the second adjusting shaft 302. One side of the sleeve 209 is fixed with a plug part 209-1. The outer circumference of the plug part 209-1 is circular. The plug part 209-1 is inserted into the second connecting ring 208 via the second plug groove 208-2. The other side of the second connecting ring 208 is detachably connected with a second plug sleeve 211. Preferably, the second plug sleeve 211 is threaded to the other side of the second connecting ring 208. The outer circumference of the second plug sleeve 211 is circular. The second plug sleeve 211 is inserted into the corresponding second connecting ring 208 via the corresponding second plug groove 208-2.

[0043] By combining the second connecting sleeve 209, the second connecting ring 208, the first connecting ring 207, and the second plug-in sleeve 211, the grooved wheels 301 in two adjacent seeders 300 are connected, and the grooved wheels 301 in several seeders 300 can move synchronously without affecting the rotation of the grooved wheels 301 during sowing.

[0044] The steps for connecting the second connecting sleeve 209 and the grooved wheels 301 at both ends are as follows: the other side of the second connecting sleeve 209 passes through the second connecting ring 208 and the next first connecting ring 207 in sequence; the insertion part 209-1 is inserted into the second insertion groove 208-2; the second insertion sleeve 211 is threaded to the other side of the second connecting sleeve 209; the next first connecting ring 207 is slid so that the next first connecting ring 207 abuts against the second insertion sleeve 211 and simultaneously fits against the left side of the next first adjusting shaft 303; the connecting bolt is screwed into the first connecting hole 207-1 and the corresponding first connecting countersunk hole to fix the first connecting ring 207 to the corresponding first adjusting shaft 303; the connecting bolt is screwed into the second connecting hole 208-1 and the corresponding second connecting countersunk hole to fix the second connecting ring 208 to the corresponding second adjusting shaft 302.

[0045] When the sliding block 201 moves, the sliding block 201 drives the grooved wheel 301 inside the seeder 300, which is close to the sliding block 201, to move via the first connecting sleeve 206. The grooved wheel 301 drives the next grooved wheel 301 to move via the second connecting sleeve 209, and so on, so as to realize the position adjustment of each grooved wheel 301, thereby realizing the adjustment of the seed dispensing volume of the seeder 300 itself. After the adjustment is completed, the fixing bolt is screwed into the second fixing hole 201-1 and the first fixing hole 402-1, and the nut is screwed on the fixing bolt on the side of the fixing plate 402 away from the sliding block 201, so that the nut abuts against the fixing plate 402, thus fixing the sliding block 201 and the frame 100, that is, fixing the position of each grooved wheel 301, which is convenient to operate.
