The invention discloses an oil peony planting device. The oil peony planting device comprises a trailer bucket, wherein the trailer bucket is of a cavity structure; a plurality of installation bases are arranged at the bottom end of the trailer bucket; a telescopic sleeve cylinder is arranged at the bottom end of each installation base; a limiting block is arranged at the bottom end of each telescopic sleeve cylinder; a spring sleeves each telescopic sleeve cylinder between the corresponding installation base and the limiting block; a wheel is arranged at the bottom end of each limiting block;a traction base is arranged at one side of the trailer bucket; a rotary motor I is arranged in a cavity of the trailer bucket; a fixed base is sleeved on the rotary motor I, and is fixedly connectedwith the inner wall of the trailer bucket. The oil peony planting device has the beneficial effects that by designing a vibration block on a conveying cylinder, the blockage of seeds is avoided; by designing a spiral plate, the conveying speed of peony seeds is guaranteed; by designing a rotary disc, the guarantee is provided for the burying of the seeds; the design of the whole structure is simple, the planting efficiency of the peony is high, and the certain practicality is realized.

The invention discloses a process for producing low-power non-wire wound fixed resistors, comprising a welding procedure and a coating procedure. A braiding procedure is additionally arranged between the welding procedure and the coating procedure and comprises the steps of adding paper tapes on both ends of welded resistor semi-finished products and controlling the semi-finished products by using a braiding control box to be automatically braided into bag-packaged products. Because the loose-packaged semi-finished products are automatically braided into bags in the braiding procedure, the products are arranged in order so that the bending and the deformation of the lead-out copper wires of the products are prevented; in the coating procedure, the semi-finished products braided into the bags are welded and are dismounted into chain gears through tape dismounting heads to be delivered into a coating track by a chain, the product bending and the deformation caused by artificial operation and vibrated blanking are effectively prevented so that the straightness of the products are ensured and the delivering speeds of the chain and the track in the automatic production of the products are also ensured, and the production speed is enhanced by one time, thereby improving the production efficiency.

The invention provides a down-hole slurry pulse signal generation device. The down-hole slurry pulse signal generation device comprises a plurality of driving valves and a plurality of communication systems corresponding to the driving valves in a one-to-one mode. Due to the arrangement of the multiple driving valves, the types of generated data signals while drilling is more; due to the arrangement of the independent communication systems, the overall transmission speed can be effectively guaranteed, and the precision of detection is guaranteed to a certain extent. In addition, in combination with multiple modulation modes, the data transmission rate is further increased. The signals can be controlled to be strong or weak through selection of the outer diameter of each driving valve and the inner diameter of a limiting base so that the transmitting speed of the data signals while drilling can be guaranteed, the downhole slurry pulse signal generation device can be suitable for working environments with different wells, different displacements and different well depths, and therefore the adaptability to the various environments is greatly improved; the number of working driving valves can be controlled, and therefore high flexibility is obtained.

The invention relates to a calibration system and method for improving the accuracy of the internal reference voltage value of a chip, wherein the method includes that the burner first makes the chip to be tested enter the calibration process, and secondly, the burner cooperates with a semi-automatic burner to detect the The voltage value to be calibrated of the chip to be tested and the voltage difference between the two ends of the contact resistance, and the subtraction of the voltage value to be calibrated of the chip to be tested and the voltage difference between the two ends of the contact resistance is performed to obtain the current calibration value corresponding to the The calibration voltage value of the chip to be tested, and finally the programmer completes the calibration of the internal reference voltage value of the chip to be tested according to the judgment result of whether there is an optimal calibration voltage value.
