Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of feeder equipment, specifically is a stick feeder. BACKGROUND

[0002] The stick feeder is mainly used for feeding and preliminarily screening blocky and granular materials in various industrial production processes. The stick feeder is generally powered by a vibrating motor or a vibrating motor. When the vibrating motor is running, the inertial force generated by the eccentric block of the vibrating motor repeatedly superimposes or offsets at a specific phase, generating a composite exciting vibration force, so that the machine body makes forced vibration on the supporting spring, thereby bringing the material to slide and throw on the stick, realizing the forward feeding of the material. The sticks of the stick feeder are arranged in a strip shape and have certain gaps. During the feeding process, the materials larger than the stick gap are blocked by the sticks and continue to move forward on the sticks, and the materials smaller than the stick gap fall into the material receiving equipment below through the stick gap, achieving the purpose of screening.

[0003] The existing defects are that the sticks of the traditional stick feeder are parallelly and fixedly arranged. During the material screening process, the materials continuously impact the sticks due to the falling difference, which causes serious wear of the stick surface and loud noise. At the same time, the stick gap often has the problem of blocking materials. Generally, it is manually cleared by hard pounding, which not only wastes time and effort, but also easily damages the entire device. UTILITY MODEL CONTENT

[0027] The second buffering mechanism 6 comprises a second support plate 6.1, a second support shaft 6.2, second bars 6.3, a second limiting rod 6.4 and a second compression spring 6.5; the second support plate 6.1 is fixed in the shell 1 and below the first support shaft 5.2, the second support shaft 6.2 is installed in the shell 1, six second bars 6.3 are rotatably arranged on the second support shaft 6.2, one end of the second bars 6.3 is below the first bars 5.3, the lower surface of one end of the second bars 6.3 is fixed with the second limiting rod 6.4, the second limiting rod 6.4 is sleeved with the second compression spring 6.5, one end of the second compression spring 6.5 abuts against the upper surface of the second support plate 6.1, the other end of the second compression spring 6.5 abuts against the lower surface of one end of the second bars 6.3, and the second support plate 6.1 is provided with second sliding grooves 6.11 corresponding in number to the second limiting rods 6.4, and the lower end of the second limiting rod 6.4 is slidably arranged in the second sliding groove 5.11.

[0028] Since the first buffering mechanism 5 and the second buffering mechanism 6 have the same structure, the effects are also the same, that is, the elastic force generated by the compression spring and the impact force generated during the falling of the material are mutually offset, so as to reduce the grinding ability of the material on the surface of the bars and reduce the sound generated during the falling of the material.

[0029] The shell 1 is provided with two shaft holes 1.1 corresponding to the first support shaft 5.2 and the second support shaft 6.2, so that the first support shaft 5.2 and the second support shaft 6.2 are movably arranged in the two shaft holes 1.1, facilitating disassembly. The first support shaft 5.2 and the second support shaft 6.2 are inserted into the shaft hole 1.1 and protrude from the outer surface of the shell 1, and the circumferential surface of each end of the first support shaft 5.2 and the second support shaft 6.2 is vertically provided with a through hole 7, and a limiting piece 8 is inserted into the through hole 7.

The bottom of the narrow end of the bar is provided with a hole slot 9, and the hole slot 9 is in interference fit with the first support shaft 5.2 or the second support shaft 6.2, so that the first bars 5.3 and the second bars 6.3 are respectively fixed on the first support shaft 5.2 and the second support shaft 6.2, and the bars can be easily disassembled later.

[0031] The working principle is that when the vibration motor operates, the material slides and throws on the rod, and in the process of forward feeding, the material first falls on the first rod 5.3 and the second rod 6.3 in sequence to carry out screening, when the material falls on the surface of the rod, the rod can be elastically rotated, under the action of the compression spring, the elastic force generated by the compression spring and the impact force generated in the process of the material falling are offset to each other, so as to reduce the grinding ability of the material on the surface of the rod and reduce the sound generated in the process of the material falling. Meanwhile, the rod is designed to be narrow in front and wide in back, in the process of continuously feeding the material forward, the rod can effectively prevent the phenomenon of material jamming.
