Description
Technical Field
[0001] The utility model belongs to the technical field of agricultural and forestry vegetation repair equipment in sandy areas, and in particular relates to a cutting mechanism for a salix tamarisk stubble machine and the salix tamarisk stubble machine. Background Art
[0002] In the fields of desertification control, desert border forest, sand vegetation cultivation and farmland shelterbelt in sandy areas, there are a large number of wild or artificially planted shrubs. Among various shrubs, Salix psammophila is a leading pioneer tree species for wind and sand prevention in the sandy land of Inner Mongolia. It is widely planted in the sandy land of eastern and western Inner Mongolia, including wild Salix psammophila. Due to the growth characteristics of Salix psammophila "three years to mature, more prosperous after cutting", it needs to be cut every 3-5 years. If it is not cut, the Salix psammophila will gradually wither and die. Therefore, it is of great significance to develop a professional Salix psammophila cutter that is efficient, economical and suitable for different terrains.
[0003] As a key component of the tamarisk pruning machine, the pruning machine cutter is its most important working part. Continuously developing new cutting devices can enrich the models of tamarisk pruning machines and give designers and personnel from relevant ecological management departments more choices.
[0004] Existing sandy shrub trimmers mostly use unsupported flail-type cutting devices or disc-type sawing devices, which require greater power, consume high power, and have poor trimming effects, requiring secondary trimming, and have low trimming efficiency.
[0005] Therefore, how to provide a cutting mechanism and a tamarisk trimmer that is efficient and labor-saving is a problem that technical personnel in this field urgently need to solve. Utility Model Content
[0006] In view of this, the utility model provides a cutting mechanism for a tamarisk stumping machine and a tamarisk stumping machine, which have low power consumption, high efficiency and are easy to use during stumping operations.
[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cutting mechanism for a Salix psammophila trimmer, comprising:
[0008] A tool mounting plate, the tool mounting plate is rotatably located below the frame, a plurality of guide rods are fixed to the front end of the frame corresponding to the travel, and the guide rods are arranged close to the top side of the tool mounting plate;
[0009] The cutting knife has multiple groups and is fixedly connected to the peripheral side of the tool mounting plate at intervals. The multiple cutting knives cooperate with the tool mounting plate to form a large-tooth cutting structure. There is a spacing distance between the rotation plane of the cutting knife and the bottom surface of the introduction support rod. When the cutting knife rotates to the side of the introduction support rod, it can cooperate with the introduction support rod to form a small gap shear pair.
[0010] The beneficial effects of the utility model are as follows: the cutting knife cooperates with the introduction support rod to form a supported cutting method, and multiple cutting knives cooperate with the tool mounting plate to form a large blade tooth cutting structure. The advantage of large blade tooth cutting is that the branches of the tamarisk can be cut off by the blade teeth at one time, ensuring high cutting efficiency and also ensuring the quality of the stubble. The stubble is flat and has good effect. The device uses the small gap shearing pair formed by the cutting knife and the introduction support rod to efficiently shear the branches. When the tamarisk branches enter the cutting area, they will be cut off by a large blade tooth rotating at a high speed at one time, thereby completing the stubble operation. The device forms a shearing pair under supported conditions, and the tamarisk branches are cut off by a smaller cutting force, rather than being cut off by multiple small teeth of the saw blade, or being interrupted under unsupported conditions. The shearing operation can be completed with a smaller force, low power consumption, and efficient stubble.
[0011] Preferably, a power source is installed on the frame, and the output end of the power source is drivingly connected to the tool mounting disk, and the tool mounting disk is provided with 6-8 mounting positions for installing cutting knives at intervals in the circumferential direction.
[0012] The resulting technical effect is: the power source is a hydraulic motor, and the purpose of the power source is to achieve high-speed rotation of the tool mounting disk. It should be noted that there are only 6 to 8 cutting knives on the tool mounting disk of this device, which is a large-tooth cutting structure. Compared with the 80-120 small teeth of the circular saw blade, the blade of the large teeth of this device has a larger sliding cutting angle. Increasing the sliding cutting angle within a certain range can reduce power consumption. The cutting knife forms a shearing pair under supported conditions, which can efficiently cut off branches.

In addition, the convex side of the knife portion corresponding to the arc is the rotation working direction of the cutting knife, and a sliding cutting bevel is provided below this side. The sliding cutting bevel is larger than the traditional serrated blade, and the cutting stroke is increased to reduce the cutting force. If the sliding cutting bevel is above the cutting knife, it may cause the knife to get stuck, and the branches may be stuck between the gap between the cutting knife and the guide support rod, affecting subsequent cutting.
[0015] Preferably, the radial height dimension of the knife portion corresponding to the knife mounting disc is 80 mm to 100 mm.
[0016] The resulting technical effect is that the device has a large-tooth (large blade) cutting mode, which is different from the traditional small-tooth cutting.
[0017] Preferably, the distance between the top surface of the knife portion and the bottom surface of the introduction support rod is 0.5 mm to 1 mm.
[0018] The resulting technical effect is that the gap range can ensure the shearing effect without causing the knife to get stuck.
[0019] Preferably, a plurality of connection holes are provided on the mounting position of the tool mounting plate, and the connection holes correspond to the bolt holes on the tool holder.
[0020] The resulting technical effect is that each cutting knife on the tool mounting plate is connected via a plurality of bolts, thereby ensuring a reliable fixing relationship between the cutting knife and the tool mounting plate and preventing the cutting knife from falling off easily.
[0021] Preferably, the guide support rod includes an installation section, a connecting section and a guide section from one end to the other end, the installation section is connected to the bottom side of the frame, the connecting section is provided with a groove and cooperates with the cutting knife to concentrate on cutting branches, and the guide section is provided with a guide inclined surface to guide the branches into the groove.

[0024] The beneficial effect of the utility model is that during the specific implementation, there are multiple groups of tool mounting plates and cutting knives on the frame to improve the stubble working surface, and the connection with the external traction equipment is achieved through the hanging bracket. The ground wheel can effectively support the stubble machine and reduce the load power consumption of the external traction mechanism.
[0025] Preferably, a plurality of crop dividers are provided on the top of the frame and above the introduction support rods.

DETAILED DESCRIPTION
[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0038] See the attached Figures 1 to 7According to an embodiment of the utility model, a cutting mechanism of a Salix psammophila trimmer comprises:
[0039] The tool mounting plate 1 is rotatably located below the frame 2, and a plurality of guide rods 3 are fixed to the front end of the frame 2 corresponding to the travel, and the guide rods 3 are arranged close to the top side of the tool mounting plate 1;
[0040] The cutting knives 4 are provided in six groups and are fixedly connected at intervals to the peripheral side of the tool mounting plate 1. The multiple cutting knives 4 cooperate with the tool mounting plate 1 to form a large-tooth cutting structure. There is a 0.5 mm gap between the rotation plane of the cutting knives 4 and the bottom surface of the introduction support rod 3. When the cutting knives 4 rotate to the side of the introduction support rod 3, they can cooperate with the introduction support rod 3 to form a small gap shearing pair 11 for shearing the branches of the Salix psammophila, thereby completing the pruning operation process.
[0041] In other embodiments, a power source 5 is installed on the frame 2, and the power source 5 is a hydraulic motor. The output end of the hydraulic motor is transmission-connected to the tool mounting disk 1 and drives the tool mounting disk 1 to rotate. The tool mounting disk 1 is provided with 6 mounting positions for installing the cutting knife 4 at intervals in the circumferential direction, and a cutting knife 4 is fixedly installed on each mounting position.
