Description

Technical Field

[0001] This utility model specifically relates to a forestry logging machine head, belonging to the field of forestry logging technology. Background Technology

[0002] In the forestry logging industry, efficient logging equipment is crucial for improving productivity and reducing costs. While some logging heads on the market can handle trees of varying diameters well, they are often large and heavy, which not only increases operational difficulty but also limits efficiency in dense stands or on small-diameter timber. Therefore, this paper proposes a forestry logging head. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a forestry harvesting machine head to improve operational efficiency. The machine head includes a machine body, with two sets of feeding wheel arms fixedly connected to the machine body. Each feeding wheel arm has a first feeding roller. Two sets of symmetrically arranged second feeding rollers are located in the middle of the machine body. A top branch-removing knife is located at the top of the machine body. Left and right branch-removing knives and a bottom branch-removing knife are located inside the machine body. A bottom branch-removing knife is fixedly connected to the bottom of the machine body. A length-measuring unit is fixedly connected inside the machine body. A sawing unit is fixedly connected to the bottom of the machine body.

[0004] Furthermore, a boom is fixedly connected to the top of the machine head and body, a rotary motor is fixedly connected to the top of the saw unit, a sheet metal cover is fixedly connected to the top of the machine head and body, and a lubricating oil tank is provided on the machine head and body.

[0005] Furthermore, the two first feeding rollers are symmetrically arranged, and the two second feeding rollers are V-shaped. The diameter of the second feeding rollers is smaller than the diameter of the feed wheel arm, and the second feeding rollers are located in the middle of the machine head and body.

[0006] Furthermore, the top debranching knife is located above the left and right debranching knives, the left and right debranching knives are located above the length measuring unit, the length measuring unit is located above the second feeding roller, the bottom debranching knife is located below the second feeding roller, and the bottom debranching knife is located below the bottom debranching knife.

[0007] Furthermore, the machine head and body are load-bearing and are integrally welded structures.

[0008] Furthermore, the lubricating oil tank is provided in three sets: one set of the lubricating oil tank is installed on one side of the boom, one set of the lubricating oil tank is installed below the second feeding roller inside the machine head body, and one set of the lubricating oil tank is installed above the sheet metal guard on the boom.

[0009] Beneficial effects:

[0010] I. This utility model, through two first feeding rollers and two second feeding rollers, can better increase the friction between the rollers and the trees, prevent slippage during feeding, reduce damage to the trees, and make timber processing more convenient and faster. It also reduces the friction between the trees and the machine body when the trees pass through. Furthermore, the second feeding roller adopts a V-shaped structure, which can perfectly fit trees of different diameters.

[0011] II. The top branch-removing blade, left and right branch-removing blades, and bottom branch-removing blade of this utility model are all movable, and the angle can perfectly fit trees of different diameters, making it more convenient and powerful to remove branches. The saw unit adopts an assembly device, with the hydraulic cylinder and device integrated into a single structure, without excessive redundancy, reducing the failure rate. The machine head and body adopt a load-bearing integrated welded body structure, which ensures the strength of the body while minimizing the weight of the body, effectively utilizing the body space, and making the machine more compact.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 As shown, a forestry logging machine head includes a machine head body 1. Two sets of feeding wheel arms 2 are fixedly connected to the machine head body 1. The feeding wheel arms 2 are provided with first feeding rollers 3. Two sets of second feeding rollers 4 are symmetrically arranged in the middle of the machine head body 1. A top branch removal knife 5 is provided at the top of the machine head body 1. Left and right branch removal knives 6 and a bottom branch removal knife 7 are provided inside the machine head body 1.
