The utility model discloses a portable mulching device for mountain crops, belongs to the field of agricultural machinery, including base and film, the bottom fixed connection of base has the push flat plate, and push flat plate's trapezoidal setting, the top of base is swingingly connected with the control mechanism through the bearing, the inside of film swingingly connects in film, and both ends of control mechanism all swingingly connect with the connecting frame through the pivot, it is through positive and negative thread drive rod cooperation drive block structure, makes the inserted rod to be able to quick tension film reel, and the interval of synchronous regulation push wheel and flat wheel, adapts to different topography and operation demand, simplifies the complex assembly process of traditional mulching equipment, secondly, the push flat plate pre -leveling ground, and push wheel is stable in soft soil in the V -shaped anti -trapping strip and advances, avoids the equipment subsidence, and the flat wheel is through the sliding fit of connecting rod, ensures that the film is uniformly compacted, improves the mulching quality, thereby the portability and operating flexibility of equipment have been improved significantly.

This invention discloses a wedge-shaped linkage side-pressure mold for composite material molding, including an upper mold and a lower mold, a side-pressure mechanism, and a linkage component. The side-pressure mechanism has an integrally formed fiber-reinforced composite layer on both the pressing surface of the side-pressure plate and the supporting surface of the pressing part. The fiber-reinforced composite layer uses metal or ceramic as a matrix, in which reinforcing fibers are dispersed. The reinforcing fibers are selected from a combination of carbon fiber and glass fiber, and their type is consistent with the type of reinforcing fibers in the product to be molded. When the upper mold closes to the lower mold, the linkage component drives the side-pressure plate to move towards the side of the mold cavity through an inclined transmission structure, so as to cooperate with the pressing part to press the product in the mold cavity from both sides. This invention converts the vertical clamping force of the upper mold into the lateral movement of the side-pressure plate. This transmission process ensures that the lateral clamping force and the clamping force have a definite proportional relationship, thereby maintaining basic stability throughout the molding process and avoiding the nonlinear increase problem of side pressure caused by changes in compression of traditional nitrogen springs.
