Description

Technical Field

[0001] This utility model relates to the field of sweet potato planting technology, and in particular to a seedling planting device for sweet potato planting. Background Technology

[0002] Sweet potato, also known as yam or sweet potato, is an important food and economic crop. Its tubers are rich in starch, sugar and various vitamins. It is widely planted around the world and has multiple values, including food, feed processing and industrial raw materials. It is of great significance to ensuring food security and promoting agricultural economic development. In the process of sweet potato planting, seedling planting is a key link that determines the later growth status and yield, and the seedling planter is a commonly used sweet potato seedling planting tool.

[0003] Existing sweet potato seedling planters are generally designed with a smooth rod structure. When users hold the device with sweaty palms, it is easy for the device to tilt and slip. At the same time, the built-in pointed clips of existing sweet potato seedling planters are generally designed with a fixed opening angle, which cannot be flexibly adjusted according to different sweet potato seedling sizes, which can easily cause some small sweet potato seedlings to be planted at an angle that is tilted.

[0004] Therefore, this utility model proposes a seedling planting device for sweet potato planting. Utility Model Content

[0005] Therefore, in order to overcome the problems of low anti-slip performance and need to improve the adaptability of common sweet potato planting seedling devices, this paper proposes a solution.

[0006] The technical solution of this utility model is as follows: a seedling planting device for sweet potato planting, including a pull rod frame, an annular base frame, and pointed clips. The annular base frame is fixedly installed on the outer wall of the bottom end of the pull rod frame. Two sets of pointed clips are hinged to the bottom end of the annular base frame through a movable component. A handle and a reinforcing crossbar are installed on the outer side of the pull rod frame from top to bottom. The handle is set in a U-shape and is slidably installed on the outer side of the pull rod frame. The reinforcing crossbar is fixedly installed on the outer side of the pull rod frame. Ear plates are provided on the side outer walls of both sets of pointed clips. Pull wires are symmetrically arranged on the bottom outer wall of the reinforcing crossbar, and the bottom end of the pull wires is fixedly installed on the side of the ear plates. Two sets of sliding grooves for the pull wires to pass through are correspondingly opened inside the reinforcing crossbar.

[0007] A flexible buffer assembly is installed between the handle and the reinforcing crossbar. An opening control assembly is provided on the outer side of the pull rod frame, and a positioning grip assembly is installed on the inner side of the handle.

[0008] Preferably, the flexible buffer assembly includes a limiting cylinder, a limiting piston rod, and a return spring. The limiting cylinder is fixedly installed on the outer wall of the bottom end of the reinforcing crossbar at the middle position. The limiting piston rod is slidably installed inside the limiting cylinder. The protruding end of the limiting piston rod is located above the limiting cylinder and is connected to the outer wall of the bottom end of the handle. A return spring is installed between the outer wall of the bottom end of the limiting piston rod and the inner wall of the bottom end of the limiting cylinder.

[0009] Preferably, the limiting cylinder is filled with damping fluid, and the top outer wall of the limiting piston rod located at the piston disc position is symmetrically provided with two sets of cylindrical overflow grooves for the flow of damping fluid.

[0010] Preferably, the cavity opening control component includes threaded mounting slots and positioning bolts. The inner walls of the two sides of the pull rod frame located in the handle sliding area are provided with threaded mounting slots at equal intervals. The threaded mounting slots in the same group are arranged in parallel positions, and positioning bolts are threadedly installed inside the two threaded mounting slots in the same group.

[0011] Preferably, the outer wall of the annular surface of the positioning bolt at the rotating end is provided with anti-slip strips at equal intervals, and both outer walls of the anti-slip strips are provided with an arc-shaped structure.

[0012] Preferably, the positioning and gripping assembly includes a handle pad, a shaped gripping groove, and a friction pad. The handle pad is fitted onto the outer wall of the rod at the top position of the pull rod frame. The shaped gripping groove is formed on the outer side wall of the handle at the top position of the handle body, and a friction pad is fitted inside the groove of the shaped gripping groove.

[0013] Preferably, the handle pad is configured with an open structure, and the surface of the handle pad has multiple sets of sweat-absorbing grooves, and the irregular grip groove is composed of four sets of semi-cylindrical grooves.

[0014] The beneficial effects of this utility model are:

[0015] 1. When using this sweet potato planting seedling device, the design of the irregularly shaped grip groove and friction pad makes the overall device more ergonomic, better fitting the user's four-finger grip needs. The handle pad is designed to absorb sweat from the user's palm, further enhancing the stability of the device. At the same time, the incompressibility of liquids, combined with the design of flexible buffer components, slows down and buffers the movement of the limiting piston rod, extending the overall durability of the device. In addition, the limit installation of the reset spring makes it less prone to deformation and damage during long-term use, further improving the user's comfort.

[0016] 2. When using this sweet potato planting device, the installation position of the positioning bolt can be flexibly adjusted through the mechanism components. Based on controlling the installation position of the positioning bolt, the stroke length of the limit piston rod can be changed, thereby indirectly controlling the opening and closing size of the nozzle sleeve. This design allows the device to flexibly adjust the opening and closing angle of the sleeve according to the size of different sweet potato seedlings, ensuring the accuracy of the sweet potato seedling planting angle.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a seedling planting device for sweet potato planting, including a pull rod frame 1, an annular base frame 2, and pointed clips 3. The annular base frame 2 is fixedly installed on the outer wall of the bottom end of the pull rod frame 1. Two sets of pointed clips 3 are hinged to the bottom end of the annular base frame 2 through a movable component. A handle 4 and a reinforcing crossbar 5 are installed on the outer side of the rod of the pull rod frame 1 from top to bottom. The handle 4 is set in a U-shape and is slidably installed on the outer side of the rod of the pull rod frame 1. The reinforcing crossbar 5 is fixedly installed on the outer side of the rod of the pull rod frame 1. Ear plates are provided on the outer side walls of the two sets of pointed clips 3. Pull wires 6 are symmetrically provided on the outer side of the bottom end of the reinforcing crossbar 5, and the bottom end of the pull wires 6 is fixedly installed on the side of the ear plates. Two sets of sliding grooves for the pull wires 6 to pass through are correspondingly opened inside the reinforcing crossbar 5.

[0028] A flexible buffer assembly 7 is installed between the handle 4 and the reinforcing crossbar 5. An opening control assembly 8 is provided on the outer side of the pull rod frame 1, and a positioning grip assembly 9 is installed on the inner side of the handle 4.

[0029] It should be noted that the specific way the pointed sleeve 3 is hinged to the bottom of the annular base frame 2 via the movable component, and the specific way the pointed sleeve 3 and the pull wire 6 are fixedly installed, are all existing conventional operating technical structures and have not been improved. They are also existing conventional operating technical means and will not be described in detail here.

[0030] The flexible buffer assembly 7 includes a limiting cylinder 701, a limiting piston rod 702, and a reset spring 703. The limiting cylinder 701 is fixedly installed on the outer wall of the bottom end of the reinforcing crossbar 5 at the middle position. The limiting piston rod 702 is slidably installed inside the limiting cylinder 701. The protruding end of the limiting piston rod 702 is located above the limiting cylinder 701 and is connected to the outer wall of the bottom end of the handle 4. The reset spring 703 is connected between the outer wall of the bottom end of the limiting piston rod 702 and the inner wall of the bottom end of the limiting cylinder 701. The limiting cylinder 701 is filled with damping fluid. Two sets of cylindrical overflow grooves 704 for the damping fluid to flow are symmetrically opened through the outer wall of the top end of the limiting piston rod 702 at the piston plate position.

[0031] The limiting cylinder 701 is filled with damping fluid, and a cylindrical overflow groove 704 is opened inside the limiting piston rod 702. When the handle 4 is forced to move the limiting piston rod 702 within the limiting cylinder 701, the damping fluid needs to flow through the cylindrical overflow groove 704 on both sides of the piston plate to create resistance to the movement of the limiting piston rod 702. By utilizing the incompressibility of the liquid, the overall durability of the device is extended while slowing down and buffering the movement of the limiting piston rod 702.

[0032] The opening control component 8 includes threaded mounting grooves 801 and positioning bolts 802. The inner walls of the rods on both sides of the lever frame 1, located in the sliding area of ​​the handle 4, are provided with threaded mounting grooves 801 at equal intervals. The threaded mounting grooves 801 in the same group are arranged in parallel positions, and positioning bolts 802 are threadedly installed inside the two threaded mounting grooves 801 in the same group. Anti-slip strips are provided at equal intervals on the outer wall of the annular surface of the positioning bolts 802 located at the rotating end, and the outer walls on both sides of the anti-slip strips are set with arc-shaped structures.

[0033] The anti-slip strip here is designed to increase the friction between the user and the outer wall of the positioning bolt 802, making it more stable and convenient for the user to install and remove the positioning bolt 802.

[0034] The positioning grip component 9 includes a handle pad 901, a shaped grip groove 902, and a friction pad 903. The handle pad 901 is sleeved on the outer wall of the rod at the top position of the pull rod frame 1. The shaped grip groove 902 is opened on the outer side wall of the handle at the top position of the handle 4. The friction pad 903 is fitted inside the groove of the shaped grip groove 902. The handle pad 901 is set as an open structure, and multiple sets of sweat-absorbing grooves are opened on the surface of the handle pad 901. The shaped grip groove 902 is composed of four sets of semi-cylindrical grooves.

[0035] The irregular grip groove 902 is designed to conform to ergonomic design, which can more stably fit the user's four-finger grip needs. The design of the handle pad 901 and friction pad 903 increases the stability of the user's grip on the device by increasing the contact friction. The handle pad 901 is set with an open structure to facilitate the replacement of the handle pad 901 in the future.

[0036] Working principle: See Figures 1-2 and Figure 4 As shown, before using the device, the positioning bolts 802 need to be installed into the threaded mounting grooves 801 in the appropriate positions according to the planting requirements of the sweet potato seedlings. The closer the threaded mounting grooves 801 are to the upper end, the longer the stroke trajectory of the limit piston rod 702, which in turn means a larger opening and closing angle of the pointed sleeve 3. In actual use, the two sets of positioning bolts 802 in parallel positions can be installed into the corresponding positions according to the size of the sweet potato seedlings.

[0037] See Figure 1 and Figure 5 As shown, when actually using the device, the user's palm should first grip the top of the lever 1, and the four fingers should grip the handle 4. The handle pad 901 and friction pad 903 are designed to increase the contact friction, thereby enhancing the user's grip stability.

[0038] See Figures 1-3 and Figure 5 As shown, when the seedling planting process is required, the sweet potato seedlings are first placed inside the pointed clip 3 and inserted into the soil. Then, the handle 4 is pulled upwards, and the upward movement of the handle 4 will automatically drive the limiting piston rod 702 to move upwards. The limiting piston rod 702 will then slide automatically inside the limiting cylinder 701. When the limiting piston rod 702 moves upwards, the damping fluid inside the limiting cylinder 701 flows from one side of the piston plate to the other side through the cylindrical overflow groove 704, thereby slowing down and buffering the movement of the limiting piston rod 702. At this time, the reset spring 703 is in a stretched state due to the movement of the limiting piston rod 702.

[0039] When the handle 4 moves upward, it will automatically drive the pull line 6 upward. It should be noted that the pull line 6 is made of steel wire. When the pull line 6 moves upward, it will automatically pull the ear plates on both sides of the pointed nozzle clip 3 upward. At this time, the pointed nozzle clip 3 will automatically open with the movable component as the rotation support point, and the sweet potato seedling inside the pointed nozzle clip 3 will fall into the soil. Then, while keeping the pointed nozzle clip 3 open, the entire device can be taken out from the soil. After taking it out, release the handle 4, and the reaction force generated by the stretching of the above-mentioned reset spring 703 will automatically drive the handle 4 to reset. The principle is the same as above and will not be described in detail here.

[0040] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
