The invention discloses a floating control axial-flow type threshing method for threshing salvia hispanica. The floating control axial-flow type threshing method for threshing the salvia hispanica disclosed by the invention has the beneficial effects that a floating control axial-flow type threshing machine is adopted for implementing threshing operation, and the gravity is utilized to play a rolein natural guiding, so that the cost for power and labor is effectively reduced; simultaneously, a motor drives a transmission shaft to rotate, further a roller shell rotates, and threshing operationis realized by rotation of three crushing rods arranged on the roller shell, and the threshing force in the process of threshing operation is adjustable, so that the loss of the damage of threshed salvia hispanica seeds due to nonuniform threshing force is effectively reduced; when abnormal conditions or accidents occur in the threshing process, a power-control operating rod is operated, and thena power-control operating disc drives a transmission-control spline sleeve to descend rapidly to cut off power instantaneously so as to avoid further enlargement of the abnormal conditions or accidents.

The invention discloses a mechanical servo control method for axial-flow threshing. An axial-flow threshing machine with the servo feedback control function is used for applying threshing operation, the natural guide effect is achieved through gravity, and the electric power cost and the labor cost are effectively reduced; meanwhile, a transmission shaft is driven by a motor to rotate, a rolling cylinder shell thus rotates, three crushing bars arranged on the rolling cylinder shell rotate to thus achieve threshing operation, the threshing force in the threshing operation process can be adjusted as required, the operation maximum load force after adjustment is linked with a servo feedback control mechanism through an operation part to achieve the uniformity in the whole threshing process, and it is effectively reduced that due to non-uniform threshing force, seeds after threshing are damaged; with changing of the external feeding amount, the whole servo feedback control mechanism is inthe dynamic balance state, and the whole threshing operation effect is effectively guaranteed; when the abnormal condition occurs in the threshing process, a power control operating lever provides feedback control power for the servo feedback control mechanism so that it can be avoided that the abnormal condition is further extended.

The embodiment of the invention provides a processing method and device for a memory in a device based on a SW architecture. The method comprises the following steps: in the process of initializing alarge-page memory, obtaining the memory usage amount required by the device for receiving and sending messages, wherein the memory usage amount is the sum of a packet cache PKB memory usage amount anda direct memory access DMA memory usage amount; at each time aft that large page memory chunk is merged, cutting the large page memory chunk according to the memory usage amount and the preset memorylimit address to obtain the target memory chunk; filtering in a memory to be allocated of the device according to a PKB identifier or a DMA identifier to obtain a target memory block; allocating thetarget memory block to the PKB memory and the DMA memory for use by the PKB memory and the DMA memory. The device performs the method described above. The method and the device provided by the embodiment of the invention can avoid the abnormal condition that the message cannot be received and transmitted by the equipment based on the SW architecture.

The invention relates to a method for preparing 2-ethylhexanal. The reaction solution containing 2-ethyl-2-hexenal obtained by condensation and dehydration of n-butyraldehyde is used as a raw material, and first contacted with a catalyst containing Pd, Pt, Cu, and Ni to convert the aldehyde polymer into 2- Ethylhexanal, etc., are then contacted with a two-stage catalyst containing Pd, Co, and Ag, so that the remaining small amount of 2-ethyl-2-hexenal is converted into 2-ethylhexanal, and at the same time, the aldehyde polymer is further decomposed; After rectification, the still bottom liquid containing 2-ethylhexanal, 2-ethyl-2-hexenal, 2-ethylhexanol and aldehyde polymers is circulated back to the first-stage reactor to increase 2-ethyl ‑2‑hexenal conversion rate, at the same time, some high boilers such as aldehyde polymers are converted into 2‑ethylhexanal, increasing the yield of 2‑ethylhexanal. The invention can continuously produce 2-ethylhexanal with high selectivity and high yield, has good product quality and low energy consumption of three wastes.

Disclosed is an axial-flow type automatic-control threshing machine for salvia hispanica threshing. A top cover is mounted at the upper end of a main cabin, a middle power support is arranged in the middle of the main cabin, a lower power support is arranged in the lower portion of the main cabin, and an inclined discharging plate is arranged between the middle power support and the lower power support. A first transmission shaft is arranged in a drum casing, the upper end of the first transmission shaft is in fit assembly with a first spline socket, and a rotary vane, an upper control springholder and a lower control spring holder are mounted on the first transmission shaft; the lower end of the first transmission shaft is connected with a transmission control spline bushing, and the first transmission shaft is provided with a plurality of floating springs. A second transmission shaft is mounted in the lower power support, the upper end of a transmission control spline shaft is connected with the transmission control spline bushing, and the lower end of the transmission control spline shaft is connected with the second transmission shaft. A motor drives the transmission shaft tofurther drive the drum casing to rotate, and three threshing rods on the drum casing thresh with adjustable threshing force; power is cut off by a power control operating rod, so that accident worsening is avoided effectively.
