Description

Technical Field

[0001] This invention relates to the field of harvesting machinery technology, and more specifically to a device and machine for harvesting dried safflower filaments. Background Technology

[0002] Safflower is a common flower that produces many stamens after flowering, which have significant medicinal value. Unlike fresh stamens, dried safflower stamens wilt and lie flat on the fruit cluster after a certain period, exposing the top of the flower cluster. At this point, they can be harvested with minimal effort, reducing the number of harvests and allowing for a more efficient harvesting process, similar to other crops.

[0003] However, existing safflower filament harvesting devices have two drawbacks. First, due to the spatial anisotropy of safflower plants, the fruit clusters are easily blocked during harvesting, resulting in a low harvesting rate. Second, the branches of safflower plants are relatively soft and may sway with the harvesting machine, which can easily cause damage.

[0004] Therefore, providing an efficient device and machine for harvesting dried safflower filaments is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a safflower filament harvesting device and harvesting machine, which can reduce the filament breakage rate, fruit damage rate and stem damage, and improve the harvesting rate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for harvesting dried safflower filaments, comprising:

[0008] The posture adjustment mechanism includes two spiral roller brushes with opposite spiral directions and a first drive mechanism. The two spiral roller brushes are arranged side by side and inclined to form a clamping and conveying channel between them. The tail ends of the two spiral roller brushes are connected by a gear set. The first drive mechanism is connected to the tail end of either spiral roller brush.

[0009] A harvesting mechanism, which is inclined and located directly above the clamping and conveying channel.

[0010] By adopting the above solutions, the beneficial effects of the present invention are:

[0011] Two spiral roller brushes clamp the safflower plant and transport it backward. At the same time, the friction of the spiral roller brushes pulls the safflower plant perpendicular to the axis of the spiral roller brushes, ensuring that the safflower fruit balls have a consistent posture when passing through the spiral roller brushes. Then, the picking mechanism directly acts on the top of the stamen clusters that are withered on the fruit balls. Only a small picking force is needed to detach the stamens from the fruit balls, thereby reducing the stamen breakage rate, fruit damage rate, and stem damage, and improving the harvesting rate.

[0012] Furthermore, the picking mechanism includes a picking shaft, a picking roller, and a second drive mechanism. The picking shaft is located directly above the clamping and conveying channel; the picking roller is fitted and fixed on the picking shaft; and the second drive mechanism is connected to the tail end of the picking shaft.

[0013] The beneficial effect of adopting the above-mentioned further technical solution is that the spiral roller brush and the picking mechanism are driven by different drive mechanisms, which can produce different motion patterns.

[0014] Furthermore, the dried safflower filament harvesting device also includes an inlet mechanism, which includes a connector and a guide cone. The front end of the harvesting shaft is rotatably connected to the connector, and the guide cone is fixed on the connector.

[0015] The beneficial effects of adopting the above-mentioned further technical solutions are to avoid blockages before the safflower plants enter the clamping and conveying channel (harvesting area) and to guide the safflower plants into the clamping and conveying channel.

[0016] Furthermore, each of the spiral roller brushes includes a roller brush shaft and bristles, the bristles being fixed on the roller brush shaft and distributed in a spiral shape to form the clamping and conveying channel between two of the bristles; the two roller brush shafts are connected by the gear set; the first drive mechanism is connected to the tail end of any of the roller brush shafts.

[0017] The beneficial effect of adopting the above-mentioned further technical solution is that the bristles are distributed in a spiral shape, thereby realizing the backward transport of safflower.

[0018] Furthermore, the bristles located at the front end of the roller brush shaft are tapered.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is that it helps guide the safflower plant into the clamping and conveying channel.

[0020] Furthermore, the bristles are made of a flexible material.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is to reduce damage to the filaments.

[0022] A safflower filament harvesting machine includes a walking frame and a safflower filament harvesting device as described above, wherein the safflower filament harvesting device is fixed inside the walking frame.

[0023] By adopting the above solutions, the beneficial effects of the present invention are:

[0024] When harvesting safflower plants, the machine moves forward and pulls the plants. The two spiral bristles can reduce this force and achieve better harvesting.

[0025] Furthermore, it also includes two vertical bearings with mounting brackets, which are respectively installed on the two roller brush shafts near their tail ends, and both vertical bearings with mounting brackets are fixed to the traveling frame by support seats. The front ends of the two roller brush shafts are rotatably connected to the traveling frame. The first drive mechanism and the second drive mechanism are both installed on the traveling frame. The second drive mechanism is connected to the tail end of the picking shaft by a universal coupling. A hanging member is fixed to the top end of the connecting member, and the hanging member is hung on the traveling frame.

[0026] The beneficial effect of adopting the above-mentioned further technical solutions is to increase structural stability. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figure 1-8 As shown, this embodiment of the invention discloses a safflower filament harvesting device, including a posture adjustment mechanism 1 and a harvesting mechanism 2. The posture adjustment mechanism 1 includes two spiral roller brushes 11 with opposite spiral directions and a first driving mechanism. The two spiral roller brushes 11 are arranged side by side and inclined to form a clamping and conveying channel between them, so as to clamp the safflower plant and convey it backward. The tail ends of the two spiral roller brushes 11 are connected by a gear set 12. The first driving mechanism is connected to the tail end of either spiral roller brush 11. The harvesting mechanism 2 is inclined and located directly above the clamping and conveying channel. In this invention, two spiral roller brushes 11 clamp the dried safflower plant and transport it backward. At the same time, under the dragging action of the friction of the spiral roller brushes 11, the safflower plant is made perpendicular to the axis of the spiral roller brushes 11, ensuring that the safflower fruit balls have a consistent posture when passing through the spiral roller brushes 11. At the same time, the inclined distribution method can ensure that all the safflower fruit balls are exposed and picked during the harvesting process, which makes it easy for the harvesting mechanism to directly act on the top of the stamen clusters attached to the fruit balls. Only a small harvesting force is needed to detach the stamens from the fruit balls, thereby reducing the stamen breakage rate, fruit damage rate and stem damage, and improving the harvesting efficiency.

[0038] Specifically, the picking mechanism 2 includes a picking shaft 21, a picking roller 22, and a second drive mechanism. The picking shaft 21 is inclined and located directly above the clamping and conveying channel. The picking roller 22 is fitted and fixed on the picking shaft 21. The second drive mechanism is connected to the tail end of the picking shaft 21. The spiral roller brush 11 and the picking mechanism 2 are driven by different drive mechanisms, which can produce different motion forms, such as differential speed or constant speed. In this embodiment, both the first drive mechanism and the second drive mechanism are electric motors or hydraulic motors. In addition, the picking roller 22 can be a straight bristle, a spiral bristle, a bristle arrangement, or an intermittent arrangement, or it can be other forms of picking mechanism 2, such as inclined comb teeth, inclined vibrating rollers, rollers, etc.

[0039] In order to further optimize the technical solution of the present invention, avoid blockage before the safflower plants enter the clamping and conveying channel (picking area), and guide the safflower plants into the clamping and conveying channel, a dried safflower filament picking device also includes an inlet mechanism 3. The inlet mechanism 3 includes a connector 31 and a guide cone 32. The front end of the picking shaft 21 is rotatably connected to the connector 31; the guide cone 32 is fixed on the connector 31.

[0040] Specifically, each spiral roller brush 11 includes a roller brush shaft 111 and brush bristles 112. The brush bristles 112 are fixed on the roller brush shaft 111 and are spirally distributed to form a clamping and conveying channel between the two brush bristles 112. The spiral brush bristles 112 can ensure that the pulling force generated on the plant during the forward movement is canceled out by the pulling effect generated by the friction of the spiral roller brush, so that the safflower plant is always perpendicular to the axis of the spiral roller brush 11. This ensures that the safflower fruit balls have a consistent posture when passing through the spiral roller brush 11, and the plant is always clamped and conveyed by the two spiral roller brushes 11, reducing the damage caused by the swinging of the safflower plant branches during operation. The axial distribution of the two roller brush shafts 111 and the picking shaft 21 is approximately the same as the distribution of the three edges of the triangular prism. The two roller brush shafts 111 are connected by a gear set 12. The first drive mechanism is connected to the tail end of any roller brush shaft 111.

[0041] To further optimize the technical solution of the present invention, the bristles 112 located at the front end of the roller brush shaft 111 are conical, which helps to guide the safflower plant into the clamping and conveying channel.

[0042] To further optimize the technical solution of the present invention, the bristles 112 are made of a flexible material, which can reduce damage to the filaments.

[0043] This invention also discloses a safflower filament harvesting machine, including a walking frame 4 and a safflower filament harvesting device as described above, wherein the safflower filament harvesting device is fixed inside the walking frame 4. When harvesting safflower plants, the walking frame 4 generates a forward pulling force; the two spiral bristles 112 can reduce this force, achieving better harvesting.

[0044] Specifically, it also includes two vertical bearings 5 ​​with mounting brackets, which are respectively installed on the two roller brush shafts 111 near the tail end. Both vertical bearings 5 ​​are fixed to the walking frame 4 by support bases 6 to ensure that the two spiral roller brushes 11 are in a stable position adjustment state. The front ends of the two roller brush shafts 111 are rotatably connected to the walking frame 4. The first drive mechanism and the second drive mechanism are both installed on the walking frame 4. The second drive mechanism is connected to the tail end of the picking shaft 21 by a universal coupling 7. The top end of the connecting piece 31 is fixed with a hanging piece 33, which is hung on the walking frame 4.

[0045] The working process of this invention is as follows:

[0046] During the harvesting of safflower plants, the traveling frame 4 moves forward, and the safflower plants are fed into the harvesting device. The first drive mechanism drives the two spiral roller brushes 11 to rotate, and the safflower plants enter the clamping and conveying channel. The safflower plants always remain perpendicular to the axis of the spiral roller brush shaft 111, ensuring that the safflower fruit balls have a consistent posture when passing through the spiral roller brush 11. The spiral bristles 112 make the spiral roller brush 11 have a backward conveying effect on the safflower. When the safflower plants enter a certain position, the second drive mechanism drives the harvesting shaft 21, and the harvesting roller 22 performs the harvesting operation. The harvesting roller 22 can directly act on the top of the stamen clusters that are withered on the fruit ball, so only a small harvesting force is needed to detach the stamens from the fruit ball.

[0047] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
