AI Technical Summary

Problems solved by technology

The rake teeth are directly fixed on the roller. The distance between the fixed end of the rake teeth and the tip of the rake teeth is long and integrated. The workload of disassembly is large. After the head of the rake teeth is damaged, the entire rake teeth are invalid, resulting in unnecessary waste.

Embodiment 1

[0050] Figure 1 to Figure 7 It is the tine split roller harrow described in Example 1. The rake teeth split roller harrow includes rake teeth and a roller 3, the rake teeth include a tooth head 1 and a tooth head fixing seat 2, etc., the roller 3 includes a roller and / or a roller, and the tooth head 1 is coated with a wear-resistant material or Inlaid manufacturing, wear-resistant materials include cemented carbide, high-speed steel and wear-resistant alloy steel. Wherein the tooth head fixing seat 2 is arranged on the annular outer surface of the roller 3 at intervals, the tooth head fixing seat 2 is connected with the roller 3, and the tooth head fixing seat 2 and the roller 3 can be fixedly connected or movable. , can also be a one-piece structure. Each tooth head fixing seat 2 is provided with a tooth head 1, and the tooth head 1 and the tooth head fixing seat 2 are flexibly connected. Such as figure 1 As shown, the bottom of the tooth head 1 and the tooth head fixing...

Embodiment 2

[0054] Figure 8 to Figure 11It is the tine split roller harrow described in Embodiment 2. The difference from Example 1 is that the connection between the tooth head 1 and the rake tooth fixing part 2 is a convex connection, the bottom of the tooth head 1 is provided with a convex circle 11, and correspondingly on the rake tooth In the groove, the convex circle 11 is arranged in the groove, so as to realize the connection between the tooth head 1 and the fixing part 2 of the rake tooth. In addition, a convex circle 11 may also be provided on the top of the rake tooth fixing part 2 , and a groove corresponding to the bottom of the tooth head 1 may be provided. The convex circle 11 can be arranged in various directions on the bottom of the tooth head 1 or the top of the rake tooth fixing part 2, such as Figure 10 and Figure 11 shown.

[0055] Others are with embodiment 1.

Embodiment 3

[0057] Figure 12 It is the tine split roller harrow described in Embodiment 3. The difference from Example 1 is that the connection between the tooth head 1 and the rake tooth fixed part 2 is a spherical connection, the tooth head 1 is fixedly connected with the rake tooth fixed part 2 through bolts, and the tooth head 1 and the rake tooth fixed part 2 The contact surface between them is spherical.

Abstract

The invention relates to construction, engineering machinery, mine, metallurgy and port storing and shipping equipment, in particular to a rolling harrow with separated harrow teeth. The rolling harrow with separated harrow teeth is used for a rolling-harrow loader and a harrow control material feeder. The rolling harrow comprises a rolling device and harrow teeth. Each of the harrow teeth comprises a tooth bit and a tooth bit fixing base, wherein the tooth bit fixing bases are arranged at intervals on the annular surface of the rolling device, and the tooth bits are movably connected with the tooth bit fixing bases. The rolling harrow has the advantages that the harrow teeth are divided into the tooth bits and the tooth bit fixing bases, so that the tooth bits can be changed rapidly and independently after being damaged, a rolling drum and the tooth bit fixing bases are not needed to be changed, and the tooth bit fixing bases and the rolling drum can be firmly manufactured; and the tooth bits are manufactured independently, so that the manufacture cost of the rolling harrow is reduced, only the tooth bit portions of the rolling harrow are made of special materials, and compared with the fact that the whole in made of special materials, the material cost is reduced greatly; and as for random accessories, only the tooth bits are arranged, so that waste of a large number of stockpiled rolling drums is reduced.

Description

technical field [0001] The invention relates to construction, engineering machinery, mining, metallurgy, and port storage and transportation equipment, in particular to a rake tooth split roller harrow used for a roller harrow loader and a rake-controlled material feeder. Background technique [0002] The roller harrow loader improves the loading efficiency, and the harrow control feeder improves the feeding efficiency, and the feeding amount is better controlled. However, according to the needs of the site, the rake teeth of the two devices are uniform longer. The rake teeth are directly fixed on the roller. The distance between the fixed end of the rake teeth and the tip of the rake teeth is long and integrated. The workload of disassembly is large. After the head of the rake teeth is damaged, the entire rake teeth are invalid, resulting in unnecessary waste. . Contents of the invention [0003] The purpose of the present invention is to provide a rake tooth split roll...
