Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a substrate filling and covering device for seedling trays with substrate block crushing function. Technical Background

[0002] Precision seeding equipment for plug trays is a key piece of equipment in factory-scale seedling cultivation technology. With China's economic development, especially the rapid development of urban construction and the adjustment of industrial structure, the demand for vegetables and flowers is increasing. Precision seeding equipment for plug trays has been widely used due to its advantages such as saving on high-quality seeds, high and uniform germination rates, and increased yield and efficiency. However, manually filling the plug trays with substrate inevitably prolongs working time and reduces work efficiency; therefore, plug tray substrate covering devices have emerged.

[0003] Chinese utility model patent application number CN98243246.1 discloses a seeder for factory seedling raising, characterized in that: the seeder consists of a box and a seeding wheel, and equidistant left and right double-headed spiral grooves are machined axially on the circumferential surface of the cylindrical body of the seeding wheel. The spacing of the spiral grooves corresponds to the row spacing of the seedling tray holes. The seeding wheel rotates to spread the substrate into the box and into the seedling tray.

[0004] However, if the substrate or soil used contains a certain amount of moisture, the surface of the seeding wheel will stick to the substrate or soil, resulting in uneven coverage and poor substrate or soil coverage.

[0005] However, the above-mentioned existing technology still has the following technical problems: when covering the seed trays with soil, the box contains a large amount of substrate or soil. Under the action of gravity, the substrate or soil containing water will gradually sink and accumulate, adhering and clumping together. When discharging, the accumulation at the discharge port will cause difficulties in discharging, or even block the discharge port. Moreover, the L-shaped scraper in the chain scraper can only divide the large pieces of substrate that are adhering into small pieces of substrate, but cannot break them up, resulting in poor covering effect. Utility Model Content

The distance between the substrate scraping mechanism 13 and the substrate storage and mixing mechanism 11 can be adjusted by the adjustable bracket 15, which can adjust the amount of substrate scraped out and also facilitate disassembly and maintenance after the device becomes clogged.

[0027] For further details, please refer to Figure 3 The substrate storage and stirring mechanism 11 includes a storage tank 111, a stirring rod 112, and a third drive motor. The storage tank 11 is fixedly installed above the seed tray conveying mechanism 12 by a bracket and is used to store substrate.

[0028] Furthermore, a substrate discharge adjustment plate 113 is provided above the opening side of the storage box to adjust the amount of substrate scraped out.

[0029] Furthermore, the matrix storage and stirring mechanism 11 is equipped with at least one stirring rod 112, and these stirring rods 112 are installed in an alternating manner.

[0030] In this embodiment, the staggered stirring rods 112 can make the stirred and broken matrix blocks smaller and finer, improving the crushing effect while also crushing some unscreened impurities, preventing the device from being blocked by impurities.

[0031] For further details, please refer to Figure 4 The substrate scraping mechanism 13 includes a substrate scraping component 131, a drive shaft 132, a driven shaft 133, and a first drive motor 134.

The second drive motor 163 is connected to the brush 162 via a belt to drive the brush 162 to rotate, level the substrate-covered substrate, and remove excess substrate.

[0034] In this embodiment, the rotation direction of the brush 162 is opposite to the movement direction of the acupuncture plate, in order to improve the leveling effect of the acupuncture plate.

[0035] For further details, please refer to Figure 6 The substrate filling and covering device 10 with substrate block crushing function also includes a substrate width adjustment mechanism 14. The substrate width adjustment mechanism 14 includes a substrate guide rail 141, a guide rail fixing seat 142, and a fixing knob 143. The substrate conveying mechanism 12 is fixedly installed on both sides of the guide rail fixing seat 142.

The fixing knob 143 is used to fasten the substrate guide rail.

[0036] When implementing this utility model, the staff first needs to adjust the hole tray width adjustment mechanism 14 according to the hole tray specifications so that the hole tray moves in the direction of the hole tray conveying mechanism 12 under the guidance of the hole tray guide rail 141. After adjustment, the hole tray is placed on the hole tray conveying mechanism 12, the device is started, the third drive motor rotates, driving the stirring rod 112 to rotate, and the substrate in the substrate storage and stirring mechanism 11 is initially stirred and broken. At the same time, the hole tray moves in the required direction. When the front end of the hole tray moves to below the opening of the substrate storage and stirring mechanism 11, the first drive motor 134 rotates, driving the drive shaft 132 to rotate, so that the substrate scraping component 131 wrapped around the drive shaft 132 and the driven shaft 133 moves synchronously. The substrate scraping component 131 breaks up the small pieces of substrate that are stuck together and scrapes out the substrate, so that it falls into the hole tray. After the hole tray is filled with substrate, it continues to move in the required direction and passes through the hole tray leveling mechanism 16. The reverse rotating brush 162 levels the substrate, completing the covering and removing excess substrate at the same time.

[0037] The modules or units in the device of this utility model embodiment can be merged, divided, and deleted according to actual needs.
