Description

Technical Field

[0001] This utility model relates to a branch crushing device. Background Technology

[0002] In orchards, fruit trees need to be pruned regularly to ensure ventilation and light penetration. However, a large number of pruned branches fall into the orchard and need to be collected and disposed of. Dragging the branches directly is labor-intensive and takes up a lot of space in the truck bed.

[0003] The existing device uses a set of rotary cutters to cut and collect branches into segments. The applicant found that when making direct cuts, the branches tend to deviate, causing damage or chipping to the blades, resulting in uneven segment lengths and significant wear on the rotary cutters.

[0004] Traditional equipment uses rotary tillers, which directly cut through an input shaft using rotary cutters. This results in uneven force on the rotary cutters, and the rotary cutters have low torque, making them prone to tooth breakage, blade chipping, or inability to cut properly and feed food.

[0005] Ensuring uniform cutting lengths, protecting the blade, improving cutting efficiency, and facilitating subsequent operations have become urgent technical challenges. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a branch crushing device.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: To pre-treat cut branches and reduce the workload of the cutter, a branch crushing device includes a frame body; a pre-rolling assembly is provided on the frame body. The pre-rolling assembly includes at least one set of meshing teeth; The meshing gear set includes a lower meshing shaft and an upper meshing shaft that mesh with each other; The centerline of the upper meshing shaft is fixed or can be moved up and down relative to the centerline of the lower meshing shaft.

[0008] As a further improvement to the above technical solution: As is standard practice, a crushing component is installed behind the pre-rolling component; The shredding assembly includes a rotating rotary cutter or a roller cutter; To facilitate the transport of branches and leaves, a feeding channel is provided between the lower meshing shaft and the upper meshing shaft; To facilitate the extrusion and feeding of branches and leaves, the height opening of the feeding channel is smaller than the set size; A feeding port is provided in front of the bite teeth assembly; After passing through the feeding channel and the biting teeth, the flattened branches are fed into the crushing component for cutting.

[0009] To facilitate the picking up of branches and leaves and feeding them into the feeder, a front fork claw is provided at the lower front of the pre-rolling assembly. The front fork pawl is below the center line of the lower engagement shaft. The fork pawl clearance is greater than the set value.

[0010] To facilitate power transmission and traction connection, a connecting part and / or power transmission shaft are provided on the vehicle frame; The connecting part is used to connect to the tractor; The drive shaft is used to connect to the rear output shaft of the tractor.

[0011] To increase the flexibility of the connection and accommodate stones or other hard objects, the upper meshing shaft is positioned above the lower meshing shaft via an elastic pressure rod that moves up and down.

[0012] The lower meshing shaft engages with the upper meshing shaft via spur teeth or helical teeth. The spur teeth enable rapid flattening or rolling. The helical teeth allow for adjustment of the axis of the branches and leaves, thereby flattening the other parts of the shaft.

[0013] Several process breaks are provided on the lower meshing shaft and / or the upper meshing shaft respectively, so as to achieve axial compression of the branches and leaves.

[0014] To prevent adjustment of the axial position of branches and leaves, the meshing teeth assembly includes a left meshing section and a right meshing section along the axial direction. To facilitate the adjustment of the branch and leaf positions, the spiral teeth of the left and right meshing sections rotate in opposite directions.

[0015] In order to fully engage the concentrated branches and leaves, a middle engagement section is provided between the left and right engagement sections; The left and right meshing sections have trapezoidal teeth, which increases strength, prevents tooth breakage, and provides high compressive force.

[0016] The middle section of the meshing part is a straight tooth meshing.

[0017] To prevent the branches and leaves from becoming horizontal, the direction of the branch and leaf conveying is adjusted to prevent the branches and leaves from entering the upper part of the upper meshing shaft. A horizontal stop bar is installed in front of the upper meshing shaft at the feeding port. Vertical adjustment rods are installed at intervals in front of the feeding port; For easy fixing, the middle part of the vertical adjustment rod is installed on the horizontal stop.

[0018] This utility model is reasonably designed, low in cost, sturdy and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and easy to use.

[0019] Compared to the optical axis roller pressing, this utility model has meshing teeth, which generate feeding driving force and avoid slippage. As the basic mechanism, the power transmission shaft and the lower meshing shaft realize fixed connection and power output.

[0020] The upper meshing shaft is upgraded by controlling the elastic downward pressure rod, thereby enabling the passage of stones and knots. Axial rolling is achieved through the process fracture. The left and right meshing parts achieve rolling and concentration of branches. The middle meshing part achieves rolling in the direction of travel, thereby maintaining the protection of the meshing teeth and avoiding problematic meshing. This utility model can meet various working conditions in orchards and can pre-roll and press branches of different sizes (1cm-10cm).

[0021] This invention uses a spiral hobbing gear, which can feed in some medium to finer branches and cut them directly. Very fine branches can be processed by a rotary cutter.

[0022] For thick branches, this invention can be used to roll and flatten them into fibers, thereby reducing the workload of the rotating blade.

[0023] For example, a 10cm branch can be rolled and flattened into 2-5cm fibers.

[0024] The spiral has high extrusion force and torque, axial rubbing force, and automatic adjustment and conveying functions.

The branch is squeezed and clamped by the crushing component 5, thus achieving cutting without tilting.

[0039] A fork pawl 4 is provided at the lower front of the pre-rolling assembly 3, so as to pick up fallen branches and twigs and feed them automatically.
