The application relates to the walnut processing technical field and discloses a walnut ultrasonic shell breaking and kernel taking device, which comprises a rack, a walnut conveying mechanism arranged on the rack, a walnut shell breaking mechanism and a material collecting mechanism. The walnut conveying mechanism is used for driving the fallen walnuts to move and is conveyed to the walnut shell breaking mechanism. The walnut shell breaking mechanism drives the walnuts to move and extrudes the walnuts to break the shells through ultrasonic high-frequency vibration. The material collecting mechanism is used for screening and collecting the walnut kernels and the walnut shells after the shells are broken. The walnut conveying mechanism, the walnut shell breaking mechanism and the material collecting mechanism realize the processes of walnut conveying, extrusion shell breaking and recovery. The ultrasonic wave is applied to the walnut shell breaking field. The walnut shells in Yunnan are hard and have small kernel-shell gaps. The high-frequency vibration under the mechanical effect of the ultrasonic wave is suitable for the characteristics of hard and brittle material breaking, assists the walnut shell breaking, and improves the shell breaking rate and the whole kernel rate.

The utility model discloses a production device suitable for processing small-particle-size cotton seeds, which belongs to the field of cotton seed processing, and comprises a delinting machine, a delinting machine, a quintuplet sieve, a delinting machine, a delinting machine, a screening device, a softening device and a drying device, the distance between saw blades of the delinting machine is set to be 8.8 mm, a dial is arranged between a seed poking roller of the delinting machine and sawteeth, and the delinting machine is connected with the delinting machine. Adjusting the tangential angle of an impurity removal knife of the delinting machine to be 15-30 degrees, and forming an impurity removal opening in a down drawing air duct; the down cleaning machine adopts two-stage down cleaning, the angles of a first-stage impurity removal cutter and a second-stage impurity removal cutter of the down cleaning machine are set to be different, and the down cleaning machine adopts a 40-mesh dust cage net surface; the husking machine adopts a double-roller husking machine, and the differential ratio of a fast roller to a slow roller of the husking machine is adjusted; and the screening device adopts a winnowing type step screen, a plane screen and a vibrating screen which are matched step by step. According to the utility model, the cotton linter output rate of small-particle-size cotton seeds can be greatly improved, the protein residual oil is reduced, the protein content is improved, and the product quality is improved.

The utility model relates to a buckwheat huller capable of dynamically adjusting pressure, and belongs to the technical field of grain hulling. The device comprises a rack and a box body, wherein the box body is arranged on the rack; a feeding hole communicated with the outside is formed in the top of the box body, and a discharging hole is formed in the bottom of the box body; a partition plate is arranged in an inner cavity of the box body and divides the inner cavity of the box body into a rubbing hulling cavity and a screening cavity. The top of the rubbing shelling cavity is communicated with the feeding hole; the inner wall of the rubbing shelling cavity is connected with a rubbing shelling mechanism; a connecting frame is arranged in the screening cavity and provided with a screening mechanism. The multiple groups of fixed rubber roller assemblies and the multiple groups of movable rubber roller assemblies can be adjusted, so that the hulling requirements on tartary buckwheat or other materials with different physical properties in actual production are met; and the acting force on the buckwheat grains is always in a low-pressure state, so that a relatively high whole kernel rate is ensured.

The invention relates to the field of agricultural mechanical equipment, in particular to a conical drum type buckwheat huller which comprises a rack, a hulling drum, a main shaft, a cylindrical shell, a gap adjusting mechanism, a transmission assembly, a feeding hopper and a motor. The main shaft is supported on the machine frame through the gap adjusting mechanism, the hulling roller is fixed to the main shaft, the transmission assembly is arranged at the front end of the main shaft, the rear end of the cylindrical shell is integrally connected with a conical shell with the front portion narrow and the rear portion wide, the cylindrical shell and the conical shell are jointly arranged on the outer side of the hulling roller in a sleeving mode, and the cylindrical shell and the conical shell are both fixed to the machine frame. A discharging cover cap is installed at the rear end of the conical shell, a discharging guide groove is connected to the lower end of the discharging cover cap, the feeding hopper is installed at the top of the front end of the cylindrical shell, and the motor is arranged on the rack and connected with the main shaft through a transmission assembly; the problems that existing buckwheat hulling equipment is low in production efficiency, the whole kernel rate of buckwheat kernels is low, and the whole hull rate of buckwheat hulls is low are solved.
