The invention provides a cement deblocking machine with a magnetic resonance crushing function, and relates to the field of building cement processing equipment. The problems that a hammer head and ahammer plate can be jammed by cement in the overlarge particle size during operation of an existing cement deblocking machine and consequently the deblocking operation is time-consuming and power-wasting and low in efficiency are solved. The cement deblocking machine with the magnetic resonance crushing function comprises a machine body, a crushing mechanism, the hammer plate and a feeding port baffle. The improved cement deblocking machine has the following beneficial effects that I, the hammer plate can be prevented from being jammed by cement blocks in the large particle size through a magnetic resonance mechanism; II, the viscidity of white emulsion additives can be reduced according to the friction heating principle, and the deblocking rate of the cement blocks is increased; time andenergy are saved; III, the crushing hammer head can be prevented from being jammed by the cement blocks through cooperation of a shredding and unblocking device and a transmission cleaning mechanism,thereby benefiting normal operation of the crushing hammer head; and the timesaving, energy-saving and high-efficiency operation can be achieved through overall cooperation, and equipment parts can beprevented from being damaged by the cement blocks.

The invention discloses an anti-winding fertilizer volume control ratio layered fertilization monomer based on spiral dial throwing, which relates to the field of agricultural machinery and equipment, including a layered fertilization shovel, a spiral dial roller, a cutting disc, a driving component, and a fertilizer flow controller , fertilizer quantity control ratio distribution device and ditch opener, layered fertilization shovel includes base, shovel handle, hanging arm, main fertilizer pipe, shallow fertilizer pipe, deep fertilizer pipe, shallow fertilizer outlet and deep fertilizer outlet, spiral The dial roller is set at the front end of the shovel handle, the cutting disc is fixed at the lower part of the spiral dial roller, the main fertilizer pipe is fixed at the rear end of the shovel handle, the shallow fertilizer pipe and the deep fertilizer pipe are arranged at the lower end of the main fertilizer pipe, and the rear end of the shallow fertilizer pipe A hanging arm is fixed, and a ditch opener is installed on the hanging arm. Both the fertilizer flow control device and the fertilizer quantity control ratio distribution device are installed in the main fertilizer pipe, and the fertilizer flow control device is located above the fertilizer quantity control ratio distribution device. The device can realize the throwing of weeds and rice stubble, improve the passability of the layered fertilization shovel, realize the adjustment of the fertilizer amount in the deep and shallow layers and layered fertilization, and improve the utilization rate of the fertilizer.

The invention relates to an automatic oil feeder for an assembly line and the hook head assembly line containing the same. The automatic oil feeder for the assembly line comprises a support and an oil tank, wherein the oil tank is fixed to the support, an oil injection opening is formed in the top of the oil tank, an oil outlet pipeline is arranged on the bottom of the oil tank, and the support is provided with a control switch used for opening or closing the oil outlet pipeline in time. The hook head assembly line comprises a power device, a main drive sprocket, a guide rail and a bearing table, wherein the tail end of the bearing table is connected with the automatic oil feeder for the assembly line or the automatic oil feeder for the assembly line is fixedly arranged on the outer side edge of the rail. The automatic oil feeder for the assembly line and the hook head assembly line containing the same have the beneficial effects that lubrication and maintenance can be carried out on the assembly line automatically, artificial control is not needed, the labor cost is lowered, and the service life of equipment on the assembly line is prolonged; according to the operation condition of the assembly line, lubrication and maintenance are carried out selectively, lubricating grease is prevented from being used for a long time and at large amount, and the production cost is saved.
