Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of seeder accessories, and in particular relates to a multi-functional seed metering device. Background Technology
[0002] Currently, seed metering devices used on seeders include scoop wheel seed meterers and finger clamp seed meterers. Scoop wheel seed meterers can sow crops such as corn, soybeans, mung beans, and sorghum, but are not suitable for high-speed sowing operations. Finger clamp seed meterers are only suitable for sowing corn, do not require adjustment during sowing, and can appropriately increase the operating speed. Because different crop varieties can be sown using a single finger clamp seed meterer or a single scoop wheel seed meterer, different seeders are required for sowing different crop varieties and in different environments, causing great inconvenience and waste of resources. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a multi-functional seed metering device that can be applied to different crop varieties.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: it includes a seed metering device housing, wherein the seed metering device housing is provided with a finger clamp seed metering device core, a spoon wheel seed metering device core, and a spoon wheel seed metering device cover. The seed metering device housing is provided with a central mounting hole and a first edge mounting hole. The finger clamp seed metering device core is provided with a second edge mounting hole that matches the first edge mounting hole. The spoon wheel seed metering device cover is provided with a third edge mounting hole that matches the first edge mounting hole. The first edge mounting hole and the second edge mounting hole or the third edge mounting hole are connected by connecting bolts. The center of the spoon wheel seed metering device core is provided with a fixing bolt that matches the central mounting hole.
[0005] Its additional technical features are: the first edge mounting hole, the second edge mounting hole, and the third edge mounting hole are four of each, which are evenly arranged.
[0006] This utility model provides a multifunctional seed metering device. A seed metering device housing can be assembled with either a finger-clamp seed metering core or a spoon-wheel seed metering core and a spoon-wheel seed metering cover. When used as a finger-clamp seed metering device, the first edge mounting hole of the seed metering device housing and the second edge mounting hole of the finger-clamp seed metering core are connected by connecting bolts, thus forming the finger-clamp seed metering device. When used as a spoon-wheel seed metering device, the center of the spoon-wheel seed metering core is fixed to the center mounting hole of the seed metering device housing by fixing bolts, and the first edge mounting hole of the seed metering device housing is connected to the third edge mounting hole of the spoon-wheel seed metering cover by connecting bolts, thus forming the spoon-wheel seed metering device. This utility model provides a multi-functional seed metering device. By changing the seed metering device core, a single seeder can be used as a finger-clamp seed metering device or a spoon wheel seed metering device. One seeder can sow different crop varieties, making it convenient to use and reducing resource waste. The optimal effect is achieved by evenly distributing four mounting holes (first, second, and third edge) along the edge. Attached Figure Description

[0014] The specific structure of this utility model's multifunctional seed metering device will be further described below with reference to the accompanying drawings.
[0015] like Figure 1 , Figure 2 As shown, the seed metering device housing 1 of this utility model is provided with a central mounting hole 101 and a first edge mounting hole 102, and the first edge mounting hole 102 is four evenly arranged.
[0016] like Figure 3 , Figure 4 As shown, the finger clamp seed metering device core 2 is provided with a second edge mounting hole 201, and there are four evenly arranged second edge mounting holes 201.
[0017] like Figure 5 , Figure 6 As shown, a fixing bolt 301 is provided at the center of the core body 3 of the spoon wheel seed meterer.
[0018] like Figure 7 As shown, the seed feeder cover 302 is provided with a third edge mounting hole 303, and there are four evenly arranged third edge mounting holes 303.
[0019] This utility model provides a multifunctional seed metering device. A seed metering device housing 1 can be assembled with either a finger-clamp seed metering core 2 or a spoon-wheel seed metering core 3 and a spoon-wheel seed metering cover 302. When used as a finger-clamp seed metering device, the first edge mounting hole 102 of the seed metering device housing 1 is connected to the second edge mounting hole 201 of the finger-clamp seed metering core 2 using connecting bolts, thus forming the finger-clamp seed metering device. When used as a spoon-wheel seed metering device, the center of the spoon-wheel seed metering core 3 is fixed to the center mounting hole 101 of the seed metering device housing 1 using fixing bolts 301. The first edge mounting hole 101 of the seed metering device housing 1 is connected to the third edge mounting hole 303 of the spoon-wheel seed metering cover 302 using connecting bolts, thus forming the spoon-wheel seed metering device. This utility model provides a multifunctional seed metering device. By changing the seed metering device core, a single seeder can be used as a finger-clamp seed metering device or a spoon wheel seed metering device. One seeder can sow different crop varieties, making it convenient to use and reducing resource waste. The optimal effect is achieved by evenly distributing four mounting holes: the first edge mounting hole 102, the second edge mounting hole 201, and the third edge mounting hole 303.
