This invention relates to the field of no-till seeding devices, and more particularly to a general-purpose no-till seeding device for wheat and rapeseed, comprising: a frame, rollers, a double-disc stubble-breaking blade, a seeding mechanism, and a covering roller; a storage bin is provided on the frame; the rollers are rotatably connected to the frame; an installation block is fixedly connected to the frame; the double-disc stubble-breaking blade is rotatably connected to the installation block; a motor for driving the double-disc stubble-breaking blade is provided inside the installation block; a support rod is fixedly connected to the installation block; in this invention, soil is moved to the crushing roller on a vibrating screen by a suction air pump, crushed into small soil particles, and then screened. The small soil particles fall into the furrow through a transfer funnel and a covering pipe to complete the covering. Subsequently, the covering roller lightly presses the soil to complete no-till seeding. Covering the seeds with small soil particles prevents seed hypoxia and soil compaction, thus avoiding restrictions on seed growth and germination.

The utility model discloses a root-resistant waterproof basement roof landscape planting roof structure which comprises a structural layer, a supporting frame is placed at the upper end of a filtering layer, the interior and the exterior of the supporting frame are filled with vegetation soil layers, the inner wall of the supporting frame is fixedly connected with a threaded installation groove, and a planting bin is installed on the inner wall of the threaded installation groove in an inserted mode. According to the root-puncture-resistant waterproof basement roof landscape planting roof structure, the planting pool can be reinforced and mounted through the reinforcing blocks and the cement mounting layer, the planting pool is an integrally-formed steel mechanism and is good in stability, the vegetation soil layer can be supported through the supporting frame, soil is prevented from being too compact, growth is not affected, and the service life of the planting pool is prolonged. Cultivation can be facilitated through the planting bin, root extension can be effectively prevented through the planting bin and the supporting frame, the planting bin can be rapidly and independently disassembled and assembled through the threaded mounting groove, the root puncture resistant waterproof roll is conveniently and stably adhered through the adhesion fixing block, replacement and use are convenient, and the use effect is good.

The invention relates to the field of single crystal furnace silicon liquid overflow protection, in particular to a single crystal furnace silicon liquid drainage and collection device which comprises a heat preservation drainage layer arranged on the bottom wall of a single crystal furnace. The drainage groove penetrates through the heat preservation drainage layer, one end of the drainage groove is communicated with the interior of the single crystal furnace, and the other end of the drainage groove is communicated with the preformed hole; and the silicon liquid storage tank comprises a groove drum and a tank body, one end of the groove drum is connected with the preformed hole, and the other end of the groove drum is connected with the tank body. The device has the effect of draining and collecting leaked silicon liquid.

The utility model provides a field terrestrial plant illumination intensity adjusting device which comprises a support, a light blocking assembly is movably installed on the top of the support, a plurality of shading assemblies movably installed on the top of the support are arranged on the inner side of the light blocking assembly, and the light blocking assembly comprises a first folding support. Through the cooperation of the light blocking assembly and the multiple shading assemblies, the multiple shading assemblies can be installed at the top of the support at the noon of sunny days, so that the sufficient shading effect is provided through the multiple layers of shading nets, plants are prevented from being illuminated excessively, in cloudy weather or in the morning and evening, all or part of the shading assemblies can be taken down, and the shading assemblies are convenient to use. The illumination intensity of the plants can be accurately controlled by adjusting the number of the shading assemblies, the physiological response mechanism of the plants under the specific illumination intensity can be conveniently researched, and therefore the growth rules of the plants under different illumination can be more accurately known.

The utility model discloses a device that is beneficial to potted landscape plant seedling root cutting belongs to potted landscape plant cultivation tool field, including the pivot, the outer wall rotation of pivot is connected with the shearing knife, the inside of shearing knife is provided with the expansion component, and the expansion component includes the through groove of being arranged in one shearing knife inside, and the inner bottom of through groove is fixedly connected with the circular axle, and the outer wall rotation of circular axle is sleeved with the expansion rod, and the outside wall of expansion rod is fixedly connected with the tension spring, and the end of two tension springs is fixedly connected with the follow -up belt, and through the cooperation of each device, the stability and accuracy when potted landscape plant seedling root cutting are improved, and through the cooperation of circular axle, expansion rod, tension spring and follow -up belt, can adjust the expansion amplitude of two expansion rods according to different potted landscape plant seedlings, cooperate with push rod, clamping spring and clamping rod, can stably clamp expansion rod, make it in the potted landscape plant seedling cutting process will not need to cut the branch seedling and separate, avoid the injury branch seedling cuticle and influence its normal growth.
