Description

Technical Field

[0001] This invention belongs to the field of agricultural planting machinery technology, and specifically relates to a waterweed planting machine. Background Technology

[0002] Aquatic plants (such as Elodea nuttallii, Vallisneria natans, Hydrilla verticillata, and Ceratophyllum demersum) play a vital role in shrimp and crab pond ecosystems. They not only purify water and provide habitats for aquatic organisms but also promote ecological balance. Therefore, aquatic plant cultivation is a crucial step in shrimp and crab pond aquaculture and aquatic ecological restoration projects. Currently, pond aquatic plant cultivation mostly relies on manual planting. This involves manually dividing the plants and inserting them into the pond silt. This method is not only labor-intensive and inefficient but also results in uneven planting depth, weak root adhesion to the silt, and frequent floating of the plants upon filling with water, leading to a low survival rate.

[0003] Current aquatic plant planting machinery lacks effective anti-tangling and weed-separating structures, causing aquatic plants to easily entangle and knot at the outlet, affecting planting efficiency and quality. For example, the aquatic plant planting device disclosed in patent CN119817262A can only be used with Elodea seedlings, and the seedlings need to be trimmed and neatly arranged in the seedling tray before use. Similarly, the submerged plant planting device disclosed in patent CN116034685A requires the seedling roots to be soaked before use, and manual intervention is also required for each round of planting and replenishment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an aquatic plant planting machine to solve the problem of continuous aquatic plant delivery.

[0005] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0006] A water plant planting machine includes a mobile vehicle body equipped with:

[0007] The feed hopper has a feed inlet and a grass-cutting mechanism at its bottom, the grass-cutting mechanism being used to cut the aquatic plants falling into the feed inlet;

[0008] The chute connects to the feed inlet and is used to guide the aquatic plants to the ground.

[0009] The grass pressing mechanism, located behind the exit of the slide, is used to press aquatic plants into the silt.

[0010] Furthermore, a grass-separating mechanism is provided, including a grass-separating fork and its driving mechanism;

[0011] A fork insertion slot is provided on one side wall of the discharge port;

[0012] The grass-separating fork can be inserted into the material box from the upper end of the fork socket, slide down the fork socket to the material outlet, and then be pulled out from the lower end of the fork socket.

[0013] Furthermore, the drive mechanism includes a motor and a crank-rocker mechanism, wherein the crank is driven to rotate by the motor, and the connecting rod is fixedly connected to the grass-separating fork.

[0014] Furthermore, the grass-separating mechanism is equipped with a lifting structure for adjusting the height of the grass-separating fork.

[0015] Furthermore, the material box is equipped with a feeding mechanism, which is a screw conveyor, and is vertically arranged towards the feeding port.

[0016] Furthermore, the grass-cutting mechanism includes a cutter and a grass-cutting cylinder, wherein the cutter is driven by the grass-cutting cylinder and reciprocates within the channel between the feed inlet and the feed mechanism.

[0017] Furthermore, the grass-pressing mechanism includes a grass-pressing wheel, which is connected to the bottom of the vehicle body via a grass-pressing bracket.

[0018] Furthermore, the grass-pressing wheel is connected to the grass-pressing bracket via a swing arm, and the swing angle of the swing arm is adjustable and lockable.

[0019] Furthermore, the feed inlet, grass separating fork, slide, and grass pressing wheel are provided in multiple sets, with each set arranged side by side.

[0020] Furthermore, the material box is connected above the discharge port via a funnel-shaped opening.

[0021] The beneficial effects of this invention are as follows:

[0022] (1) The present invention provides a water plant planting machine, which cuts the whole clump of water plants into small pieces through the grass cutting mechanism in the feed box, and then peels off the cut grass with the help of the external grass separating mechanism, and finally transmits it to the ground through the slide, thereby realizing the mechanized continuous delivery of water plant seedlings and solving the problem of water plants tangling and knotting in the feed box.

[0023] (2) The present invention uses a grass pressing wheel to press aquatic plants into the silt to complete the planting operation.

[0043] The vehicle body 5 is equipped with a material box 1, a grass separating mechanism 2, a slide 3 and a grass pressing mechanism 4, which are used to realize the complete planting functions of grass storage, grass picking, conveying and pressing.

[0044] like Figure 2 and Figure 3 The material bin 1 shown has two symmetrical discharge ports 13 at the bottom, and the top of each discharge port 13 is connected to the material bin 1 through a funnel-shaped opening. A fork insertion slot 14, which is elongated, is provided on the side wall connected to the discharge port 13; a grass-separating fork 25 (… Figure 9 As shown, the material can be inserted into the feed box 1 through the fork socket 14, and the water plants at the feed port 13 can be pushed into the feed port 13 by sliding along the fork socket 14.

[0045] The feed hopper 1 is equipped with two sets of feeding mechanisms 11 and two sets of grass-cutting mechanisms 12. The feeding mechanism 11 is a screw conveyor, vertically arranged, facing the feeding port 13, used to transport the aquatic plants in the feed hopper 1 to the feeding port 13. The grass-cutting mechanism 12 works in the funnel opening between the feeding port 13 and the feeding mechanism 11, used to cut the aquatic plants transported by the feeding mechanism 11 to the feeding port 13.

[0046] like Figure 4 and Figure 5 As shown, the grass-cutting mechanism 12 includes a grass-cutting bracket 15 fixed to the bottom of the feed box 1. Two sets of cutters 18 are provided on the grass-cutting bracket 15. Each set of cutters 18 is movably connected to the grass-cutting bracket 15 through a slide rod 17 and is driven to extend and retract by a grass-cutting cylinder 16. The funnel opening side wall above the feed inlet 13 has an opening for the cutters 18 to reciprocate during extension and retraction.

[0047] like Figure 6The grass-separating mechanism 2 shown includes a fixed frame 21 and a lifting frame 23. The fixed frame 21 is fixedly connected to the vehicle body 5 and has a pair of vertical slide rails. The lifting frame 23 is vertically connected to the vertical slide rails, and a lifting mechanism 22 is provided between them to adjust the position of the lifting frame 23.

[0048] The lifting frame 23 is equipped with grass-separating forks 25 and their driving mechanism. Corresponding to the two discharge ports 13 of the aforementioned material bin 1, the grass-separating forks 25 are also configured in two sets, each fork having a fork at its front end. (Refer to...) Figure 9 As shown, the grass separating fork 25 moves in a reciprocating motion, requiring it to be able to be inserted from the upper end of the fork insertion port 14, then slide along the fork insertion port 14 to the lower end (i.e., the feed port 13), and finally be pulled out from the lower end of the fork insertion port 14 and return to the initial position.

[0049] like Figure 7 As shown, the driving mechanism in this embodiment includes a grass-dividing motor 24 and a crank-rocker mechanism. The crank 26 is rotatably connected to the lifting frame 23 and is driven to rotate by the grass-dividing motor 24. The rocker arm 27 is oscillatingly connected to the lifting frame 23. The connecting rod between the crank 26 and the rocker arm 27 is fixedly connected to the grass-dividing fork 25 (or a part of the rear end of the grass-dividing fork 25 serves as the connecting rod).

[0050] like Figure 8 The grass-pressing mechanism 4 shown includes a grass-pressing bracket 41 fixedly connected to the vehicle body 5. Two sets of swing arms 42 are provided at the bottom of the grass-pressing bracket 41, and grass-pressing wheels 43 are connected to the ends of the swing arms 42. The swing angle of the swing arms 43 is adjustable and locked by bolts, thereby adjusting the height position of the grass-pressing wheels 43 by swinging the swing arms 42. Two sets of grass-pressing wheels 43 are provided for pressing down the aquatic plants that have fallen to the ground.

[0051] like Figure 9 As shown, the slide 3 has an arc-shaped structure and is provided in two sets. One end is connected to the discharge port 13 of the material box 1, and the other end is located above the front side of the grass pressing wheel 43. It is used to guide the water grass peeled off by the grass separating fork 25 to the ground and finally pressed into the silt by the grass pressing wheel 43. The implantation depth can be changed by adjusting the height of the grass pressing wheel 43.
