Description

Technical Field

[0001] The utility model relates to the technical field of spreaders, in particular to a spreader and a material bag. Background Art

[0002] A seeder consists of a container for spreadable material and a spreading mechanism. Particles enter the spreading mechanism from the container and are evenly spread into the soil, completing the process of sowing or fertilizing. There are various types and structures of seeders on the market. Some use metal or plastic containers to hold the spreadable material, while others use bags. Using bags as containers can reduce production costs and are foldable, minimizing space requirements. Bags are commonly used as containers for spreadable material on some handheld spreaders.

[0003] However, the bags on existing spreaders are generally ordinary nylon bags. Since the bags are softer than plastic or metal containers, their shapes are not fixed and are not easy to form. Therefore, it is very inconvenient for users to put the spreadable materials into the bags. Usually, users need to hold the bag opening open while putting fertilizer in, which is inefficient and sometimes difficult to complete. As a result, the material is not put into the bag but spilled out in large quantities, causing serious inconvenience. Utility Model Content

[0031] The following is a further non-restrictive detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. In the description of the utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" can explicitly or implicitly include at least one of the features. In the description of the utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] like Figure 1-Figure 3 As shown, a spreader according to one embodiment of the present invention includes a material bag and a base 2, the bottom of which is mounted on the base 2. The material bag includes a bag body 11, which defines an interior space for accommodating a sowable material. The bag body 11 is formed with a top opening 110 and a bottom opening 111 at each end. The end of the bag body closest to the bottom opening 111 is connected to the base, and sowable material such as seeds and fertilizer is loaded into the interior space through the top opening 110. A spreading device for distributing the sowable material is provided on the base 2. The spreading device includes a drop platform 21, a drop hole 22 disposed on the drop platform 21, and an impeller 24 disposed below the drop hole 22. The material bag is positioned above the drop platform 21, which carries the sowable material within the bag body 11. During use, the sowable material falls through the drop hole 22 onto the impeller 24, which then distributes the sowable material into the soil.

[0033] In this embodiment, the base 2 further includes a hand crank 25 and a transmission mechanism 26. The transmission mechanism 26 adopts a gear transmission. The hand crank 25 is connected to the impeller 24 through the transmission mechanism 26 and drives the impeller 24 to rotate, thereby evenly spreading the sowable material into the soil.

[0034] The base 2 also includes a flow control device 23, which comprises an adjustment handle 230 and an adjustment baffle connected to the adjustment handle 230. One end of the adjustment handle 230 is rotatably connected to the base 2. A through slot 211 is defined in the sidewall of the blanking platform 21, and the other end of the adjustment handle 230 slides freely within the through slot 211. The adjustment baffle is larger than the blanking hole 22. When the adjustment handle 230 is slid, the adjustment baffle rotates relative to the blanking hole 22, causing the area of ​​the blanking hole 22 blocked by the adjustment baffle to change, and the opening size of the blanking hole 22 also changes accordingly. A plurality of protrusions 212 are protruding from the bottom of the through groove 211, and a shift groove 213 is formed between adjacent protrusions 212. A stopper 231 is provided on the adjustment handle 230. When the stopper 231 is engaged with the shift groove 213 at different positions, the area of ​​the adjustment baffle blocked on the blanking hole 22 is different, so that the opening size of the blanking hole 22 is also different, thereby making the flow rate of the spreadable material through the blanking hole 22 different.

[0035] like Figure 1 and Figure 3 As shown, the material bag is further provided with a lid 16 on the top opening 110. The lid 16 can be openably and closably mounted on the top opening 110 by means of a zipper or a button connection. The lid 16 can prevent the spreadable material from spilling out of the top opening 110 due to the tipping of the material bag during use or transportation. The lid 16 is also provided with an observation window 160 covered with a transparent plastic film, so that the user can easily know the remaining spreadable material in the material bag during use.

[0036] When loading the spreader with spreadable material, the user typically uses a tool to load granular materials such as seeds into the bag body through the top opening 110, or simply picks up the container containing the granular materials with both hands and pours the granular materials directly into the bag body through the top opening 110. However, since the bag body 11 is relatively soft compared to metal or plastic containers, it is difficult to shape, resulting in the top opening 110 not being able to remain open all the time. This makes it extremely inconvenient for the user to load the granular materials. To address this issue, the present application provides a support structure 131 on the material bag of the spreader. The support structure 131 can prop open the top opening 110 when loading the granular materials, thereby making it easier for the user to load the materials.

[0037] Specifically, if Figure 3 and Figure 4 As shown, in one embodiment, the support structure is provided as a support frame 13 located at the top opening 110. The support frame 13 extends along the edge of the top opening 110 to provide horizontal support to the top opening 110, thereby opening the top opening 110 to facilitate the user to fill materials. The support frame 13 can be provided as follows Figure 3 The closed ring in can also be set as Figure 4The opening-shaped structure in the embodiment only needs to be able to laterally support the material bag so that the top opening 110 is opened.

[0038] In another embodiment, Figure 5 and Figure 6 As shown, the support structure 131 can also provide longitudinal support for the material bag. The support structure 131 includes a horizontal support portion 18 extending in the horizontal direction, and vertical support portions 19 distributed on both sides of the horizontal support portion 18 and connected by the horizontal support portion 18. The support structure 131 is connected by the horizontal support portion 18 and the vertical support portion 19 to form an overall frame. The structure is more stable and forms the skeleton structure of the material bag, so that the soft material bag can be formed. The horizontal support portion 18 opens the material bag or the top opening 110 in the horizontal direction, and the vertical support portion 19 is connected on both sides of the horizontal support portion so that the top opening 110 can be kept directly above the base 2. The horizontal support portion 18 can be set at any height of the bag body, such as Figure 5 Located at the top opening 110, Figure 6 Located in the middle and bottom of the bag body, it only needs to be connected to the vertical support part 19 to form a stable frame to support the bag body 11 and the top opening 110.

[0039] In yet another embodiment, Figure 7-10 As shown, the support structure 131 is configured as a plurality of independent vertical support portions 19 located on the bag body 11. The vertical support portions 19 are spaced apart from each other, meaning that the support structure 131 is not connected to form a single, integrated frame. The bottom of the bag body 11 has a mounting portion 17 for mounting on the base 2. The vertical support portions 19 are positioned above the top of the mounting portion 17 and maintain a certain gap therebetween, so that the vertical support portions 19 do not contact the base 2. The longitudinal support provided by the vertical support portions 19 allows the surface of the bag body 11 to remain relatively flat in the longitudinal direction. Therefore, when filling materials, the bag body 11 is not squeezed by the materials and deformed arbitrarily like conventional material bags. Such deformation would cause the top opening to change shape, making filling extremely difficult. Therefore, in this embodiment, by providing vertical support portions 19 to vertically support the bag body, the shape of the top opening 110 can be prevented from changing arbitrarily, making it easier for the user to fill materials.

[0040] like Figure 8 and Figure 9As shown, when filling the material, since there is no support structure on the bag body between the vertical support part 19 and the base 2, the bag body can initially tilt to one side, making it difficult to fill the material from the top opening 110. The user can easily open the top opening 110 with one hand to fill the material. When the height of the accumulated material in the bag body 11 is higher than the bottom end of the vertical support part 19 by a certain distance, the top opening can be opened and held directly above the base 2 due to the outward pressure of the material on the surface of the bag body. At this time, the user does not need to manually open the top opening of the bag body, which is automatically opened, thereby facilitating the filling of the material.

[0041] The mounting part 17 can be directly the surface of the bag body 11, or a reinforcing member (not shown in the figure) can be additionally added to the surface of the bag body by sewing or other means to form the mounting part together with the surface of the bag body. The mounting part can be connected to the base 2 by nails or other conventional connection methods. Preferably, the reinforcing member is made of soft materials such as rubber or nylon cloth, so that the softness of the mounting part 17 is high, which can adapt to the shape of the base 2, so that the material bag can be installed more stably, and can be adapted to different specifications of the spreader. The support structure 131 is arranged above the mounting part 17, which can reduce the constraint of the support structure on the mounting part 17, and facilitate the deformation of the mounting part. Furthermore, the vertical support parts 19 are independently spaced apart, which can reduce the limitation of the support structure 131 on the deformation of the bag body, so that the bag body can adaptively deform when the mounting part 17 bends along the base 2, which can further reduce the limitation of the support structure on the deformation of the mounting part.

[0042] Preferably, the support structure 131 is made of an elastic body, such as a memory metal material, which can facilitate the adaptive deformation of the bag body 11 according to the use environment. For example, when the bag body 11 is installed on the base, the user can fold the material bag to reduce the occupied space during storage and transportation, and the support structure can return to its original state after the external force disappears. Furthermore, as shown in Figure 7 and Figure 10 As shown, the vertical support part 19 is arranged as a closed member with a smooth edge, which can prevent the support structure from piercing the material bag when the material bag is folded. As shown in Figure 7 and Figure 10 As shown, the shape of the support structure is not limited, and can be circular, square, or other irregular shapes not shown in the figure.

[0043] Continuing to refer to Figure 7 and Figure 10The horizontal cross-section of the material bag in the expanded state is generally rectangular. The bag body 11 includes a first pair of surfaces s1 extending along the long sides of the rectangle, and a second pair of surfaces s2 extending along the short sides of the rectangle. Preferably, vertical support portions 19 are provided on the first pair of surfaces s1 so that the top opening can be fully opened during filling. Moreover, by only providing the vertical support portions 19 on one pair of surfaces of the bag body 11, the restraint of the support structure on the bag body can be reduced, facilitating adaptive deformation of the bag body 11. Figure 10 and Figure 11 As shown, the support structure 131 is circular and located on a flat surface. When making a seed bag, the support structure 131 can be placed on the surface of the bag body 11, and then the mounting member 14 can be covered on the support structure 131. Finally, the mounting member 14 is fixed to the surface of the bag body by sewing. This can achieve a convenient and quick installation of the support structure on the material bag. The mounting member 14 can be shaped like a strip and extend along the shape of the support structure 131.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
