Description

Technical Field

[0001] This utility model relates to the field of seed metering devices, specifically a shake-proof seed-protecting scoop-type seed metering device. Background Technology

[0002] Seed metering devices are a key component in agricultural machinery, mainly used on seeders or planters. They are responsible for evenly distributing seeds into the soil according to a set quantity, spacing, and depth. They are the core device for achieving precision sowing and directly affect sowing quality and crop yield. Seed metering devices are divided into mechanical seed metering devices, air suction seed metering devices, air blowing seed metering devices, and electric seed metering devices.

[0003] When existing seed metering devices need to be used for different crops, the outer shell of the seed metering device needs to be disassembled and the internal scoop wheel replaced to make it suitable for different crops. The side cover and the outer shell are fixedly connected by multiple bolts. When it is necessary to disassemble the outer shell, all of these bolts need to be removed to take it off. However, removing multiple bolts is quite laborious and affects its working efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a shake-proof seed-protecting scoop-type seed metering device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seed metering device with anti-shaking and seed protection, comprising a seed metering device body, a first limiting block fixed to the outer wall of the seed metering device body, multiple sets of second limiting blocks fixed to the outer wall of the seed metering device body, a side cover movably installed on one side of the seed metering device body, and multiple sets of fixing blocks fixed to the outer wall of the side cover, mounting grooves being provided inside the first limiting block and the second limiting block, a bolt being installed on one side of the first limiting block, a through hole being provided in the middle of the fixing block, and the first limiting block being threadedly connected to the bolt.

[0006] By adopting the above technical solution, the side cover is installed on one side of the seed metering device body by setting multiple sets of fixing blocks in cooperation with the first limiting block and the second limiting block. This makes it easier to install the side cover without manual support. The side cover is fixed with a set of bolts, reducing the number of bolts used and making it easier to disassemble, thus improving the efficiency of disassembly.

[0007] The present invention is further configured such that a protrusion is fixed on one side of the seed metering device body, and a groove is provided on one side of the side cover, and the inner wall of the groove is provided with inclined surfaces on both sides.

[0008] Preferably, the protrusions and grooves can increase the contact area between the side cover and the seed metering device body, thereby making the side cover installation more stable.

[0009] The present invention is further configured such that a first magnetic block is fixed on one side of the fixing block, and a second magnetic block is fixed on the inner wall of the mounting groove.

[0010] Preferably, the first and second magnetic blocks attract each other, which makes the side cover more stable during installation and avoids the problem of it separating from the seed metering device body during use.

[0011] The present invention is further configured such that two sets of extrusion rods are movably installed on one side of the second limiting block, and springs are sleeved on the outer wall of the extrusion rods. A connecting block is fixed at the end of the extrusion rod, and the two ends of the springs are respectively connected to the connecting block and the second limiting block.

[0012] Preferably, the end of the pressing rod is pressed by the fixing block, and the pressing rod slides outward. When the pressing rod slides outward, it pulls the end of the spring. Under the tension of the spring, the pressing rod presses the outer wall of the fixing block, increasing the resistance and making the side cover installation more stable.

[0013] The present invention is further configured such that the end of the extrusion rod is arc-shaped.

[0014] Preferably, the arc-shaped extrusion rod can be pressed outward when the fixing block contacts the extrusion rod.

[0015] The present invention is further configured such that the inner wall of the mounting groove has two inclined surfaces, and the inner wall of the mounting groove is in contact with the outer wall of the fixing block.

[0016] Preferably, the inclined surfaces on both sides of the mounting groove make it easier for the fixing block to enter the mounting groove during installation.

[0017] The present invention is further configured such that the number of the second limiting blocks is three sets, and the three sets of the second limiting blocks are distributed on the outer wall of the seed metering device body.

[0018] Preferably, the three sets of second limiting blocks can cooperate with the fixing blocks to better limit the side cover, making the side cover installation more stable.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model is provided with a side cover, a fixing block, a first limiting block, a second limiting block, and a connecting block. The multiple sets of fixing blocks cooperate with the first and second limiting blocks, so that the side cover is installed on one side of the seed metering device body. This makes the side cover installation more convenient without manual support. The side cover is fixed with a set of bolts, reducing the number of bolts used, which makes the side cover easier to disassemble and improves the efficiency of disassembly.

[0021] 2. This utility model is equipped with a first magnetic block, a second magnetic block, a protrusion, a groove, and a pressing rod. The protrusion and groove cooperate with each other, so that the side cover can be locked more tightly. The first magnetic block and the second magnetic block attract each other, so that there is no need to manually adjust the position of the through hole inside the fixing block and the screw hole of the first limiting block, thus making the bolt installation simpler and faster. The pressing rod can squeeze the fixing block under the action of the spring, increasing the resistance and preventing the side cover from easily separating from the seed metering device body during operation.

Figure 2 and Figure 3 A protrusion 8 is fixed on one side of the seed metering device body 1, and a groove 9 is provided on one side of the side cover 2. The inner wall of the groove 9 is inclined on both sides. The protrusion and groove can increase the contact area between the side cover 2 and the seed metering device body 1, thereby making the side cover 2 more stable to be installed.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 5 A first magnetic block 10 is fixed on one side of the fixing block 3, and a second magnetic block 11 is fixed on the inner wall of the mounting groove 12. The first magnetic block 10 and the second magnetic block 11 attract each other, so that the side cover can be installed more stably and avoid the problem of it separating from the seed metering device body 1 during use.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The inner wall of the mounting groove 12 has beveled sides, and the inner wall of the mounting groove 12 fits against the outer wall of the fixing block 3. The beveled sides of the mounting groove 12 make it easier for the fixing block 3 to enter the mounting groove 12 during installation.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 There are three sets of second limiting blocks 6. The three sets of second limiting blocks 6 are distributed on the outer wall of the seed metering device body 1. The three sets of second limiting blocks 6 can cooperate with the fixing block 3 to better limit the side cover 2, making the side cover installation more stable.

[0036] Second embodiment:

[0037] Please see Figure 1 , Figure 4 and Figure 5Two sets of extrusion rods 71 ​​are movably installed on one side of the second limiting block 6, and springs 72 are sleeved on the outer wall of the extrusion rods 71. A connecting block 7 is fixed to the end of the extrusion rod 71. The two ends of the spring 72 are connected to the connecting block 7 and the second limiting block 6 respectively. When the fixing block 3 extrudes the end of the extrusion rod 71, the extrusion rod 71 will slide outward. When the extrusion rod 71 slides outward, it will pull the end of the spring 72. Under the tension of the spring 72, the extrusion rod 71 extrudes the outer wall of the fixing block 3, increasing the resistance and making the side cover installation more stable.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The end of the extrusion rod 71 is arc-shaped. When the fixing block 3 contacts the extrusion rod 71, the arc-shaped extrusion rod 71 can extrude the extrusion rod 71 outward.
