[0001] This invention relates to the field of garden tools, and in particular to a grass collection device and a lawnmower. Background Technology
[0002] When a push-type lawnmower collects grass, it is equipped with a grass collection device. The cut grass is thrown by the blades towards the grass collection device, which then collects the grass.
[0003] To facilitate the replacement of the grass collection device, some grass collection devices are detachably installed on the lawnmower body. However, based on our understanding of the relevant technology, there are usually gaps at the connection between the lawnmower body and the grass collection device when it is installed. Grass clippings or foreign objects may enter the grass collection bag and fly out from the gaps, causing grass clippings or foreign objects to fly towards the operator, which may affect the operator's experience or personal safety. Summary of the Invention
[0004] The purpose of at least one specific embodiment of the present invention is to overcome the defects of the prior art and provide a grass collection device and a lawnmower.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0006] A grass collection device, comprising:
[0007] Mounting bracket, which is suitable for mounting on the machine body;
[0008] Grass collection bags;
[0009] The grass collection bag is equipped with a connecting part and a sealing part. The grass collection bag is installed onto the mounting bracket through the connecting part.
[0010] The grass collection bag has an opening. After the mounting bracket is installed on the machine body, the opening of the grass collection bag corresponds to the grass outlet on the machine body.
[0011] The sealing part on the grass collection bag abuts against the sealing part on the machine body, thus sealing the connection between the grass collection bag and the machine body.
[0012] Furthermore, the seal is a rear cover plate that is rotatably mounted on the machine body.
[0013] Furthermore, the mounting bracket includes a first bracket and a second bracket connected to the first bracket;
[0014] The connecting part of the grass collection bag is made of rigid material. The connecting part covers the outside of the first bracket and supports the sealing part. The first bracket supports the front end of the grass collection bag and forms an opening. The second bracket extends into the grass collection bag and supports the rear end of the grass collection bag.
[0015] Furthermore, the sealing part is located on one side of the connecting part, and the sealing part is a flexible component, which is constructed as a hollow structure that is easy to deform.
[0016] When the grass collection device is installed on the machine body, the sealing part fits against the side of the rear cover plate, and the connection between the grass collection bag and the machine body is sealed, so that the inner cavity of the grass collection bag forms a closed grass collection space.
[0017] Furthermore, a stop portion is provided on the rear cover plate, which includes a side stop portion and an upper stop portion;
[0018] The side stop and the side wall of the rear cover plate form an accommodating space. When the grass collection device is installed on the machine body, the connecting part on the side of the grass collection device and the first bracket are limited in the accommodating space, and the sealing part on the side of the grass collection device abuts against the inner wall of the accommodating space.
[0019] When the grass collection device is installed on the machine body, the sealing part on the top surface of the grass collection device abuts against the upper wall of the rear cover plate, and the upper stop is located on one side of the connecting part on the top surface of the grass collection device.
[0020] Furthermore, a hook is provided at the front end of the grass collection bag on the first bracket, and the bracket is suspended from the machine body by the hook.
[0021] Furthermore, an elastic element is provided at the connection between the rear cover and the machine body. One end of the elastic element is connected to the rear cover and the other end is connected to the machine body. The elastic force of the elastic element can press the rear cover towards the side of the grass collection bag.
[0022] Furthermore, after the grass collection bag is fitted onto the outside of the mounting bracket, the grass collection bag includes a first side, a second side, a third side, a top surface, and a bottom surface;
[0023] The ends of the first side, the third side, the top surface, and the bottom surface form the opening of the grass-collecting bag;
[0024] The grass outlet on the main body of the machine faces the second side, and the grass is discharged from the outlet in the direction of the junction between the first and second sides.
[0025] Furthermore, the mesh apertures on the first side, second side, and top surface are smaller than the mesh apertures on the third side.
[0026] The beneficial technical effects of the grass collection device provided in this application compared with the prior art are as follows: the grass collection bag of the grass collection device is provided with a connecting part and a sealing part. The grass collection bag can be quickly installed onto the mounting bracket through the connecting part. The mounting bracket is installed on the machine body in a detachable manner. The grass collection device is easy to install as a whole.
[0027] Moreover, after the grass collection device is installed on the machine body via the mounting bracket, the opening of the grass collection bag corresponds to the grass outlet on the machine body, and the sealing part on the grass collection bag abuts against the sealing part on the machine body, so that the connection between the grass collection bag and the machine body is sealed, and the inner cavity of the grass collection bag forms a closed grass collection space, which can prevent foreign objects and grass clippings thrown out of the grass outlet from blowing towards the operator.
[0028] Another technical solution adopted in this application is to provide a lawnmower that includes the aforementioned grass collection device.
[0029] As can be seen from the above technical solution, the lawnmower provided in this application has the technical effect of the above-mentioned grass collection device due to the configuration of the grass collection device. During the use of the lawnmower, foreign objects and grass clippings will not fly out from the connection position between the grass collection bag and the main body of the lawnmower.

[0043] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.
[0044] Reference Figure 1 , Figure 2 , Figure 5 A grass collection device 100 includes a mounting bracket 10 and a grass collection bag 20 sleeved on the outside of the mounting bracket 10. The grass collection bag 20 is provided with a connecting part 201 and a sealing part 202. The grass collection bag 20 is installed on the mounting bracket 10 through the connecting part 201.
[0045] The grass collection bag 20 has an opening 203. After the mounting bracket 10 is installed on the machine body 300, the opening 203 of the grass collection bag 20 corresponds to the grass outlet 310 on the machine body 300.
[0046] The sealing part 202 on the grass collection bag 20 abuts against the sealing element on the machine body, thus sealing the connection between the grass collection bag 20 and the machine body.
[0047] In this embodiment, the sealing element is a rear cover plate 200 that is rotatably mounted on the machine body 300.
[0048] In some embodiments, the sealing part 202 is a flexible element, preferably rubber, which is easy to deform by compression, fits more tightly when in contact, and has a better effect in preventing grass leakage.
[0049] Specifically, the sealing part 202 can be a solid structure, preferably a hollow structure, which is easy to deform, so that when the grass collecting device 100 is installed on the machine body 300, the contact resistance between the connecting part 201 and the rear cover plate 200 is reduced, making it easy to install.
[0050] Specifically, the connecting part 201 is made of a rigid material, such as plastic. The connecting part 201 and the sealing part 202 are integrally formed during manufacturing. The connecting part 201 and the grass collection bag 20 are fixedly connected by sewing. The grass collection bag 20 is preferably made of cloth.
[0051] Furthermore, refer to Figure 2 The mounting bracket 10 includes a first bracket 101, a second bracket 102 connected to the first bracket 101, and a third bracket 103 connected between the first bracket 101 and the second bracket 102.
[0052] When the grass collection bag 20 is installed on the mounting bracket 10, the connecting part 201 of the grass collection bag 20 covers the outside of the first bracket 101. The first bracket 101 supports the front end of the grass collection bag 20 and forms an opening 203. The second bracket 102 extends into the grass collection bag 20 and supports the rear end of the grass collection bag 20. The third bracket 103 plays a stable supporting role between the first bracket 101 and the second bracket 102, ensuring the strength and stability of the entire grass collection device 100 after assembly.
[0053] In addition, a hook 104 is provided on the first bracket 101 at the front end of the grass collection bag 20. After the bracket 10 and the grass collection bag 20 are assembled, they can be suspended on the machine body 300 by the hook 104.
[0054] Furthermore, refer to Figures 4 to 11 The sealing part 202 is located on one side of the connecting part 201 and close to the rear cover plate 200. When the grass collecting device 100 is installed on the machine body, the sealing part 202 fits against the side of the rear cover plate 200, so that the inner cavity of the grass collecting bag 20 forms a sealed grass collecting space.
[0055] Specifically, the rear cover plate 200 is provided with a stop part, which includes a side stop part 210 and an upper stop part 220;
[0056] The side stop 210 and the side wall 230 of the rear cover 200 form a receiving space 240. When the grass collecting device 100 is installed on the machine body, the connecting part 201 on the side of the grass collecting device 100 and the first bracket 101 are limited in the receiving space 240, and the sealing part 202 on the side of the grass collecting device 100 abuts against the inner wall of the receiving space 240.
[0057] When the grass collection device 100 is installed on the machine body, the sealing part 202 on the top surface of the grass collection device 100 abuts against the upper wall of the rear cover plate 200, and the upper stop part 220 is located on one side of the connecting part 201 on the top surface of the grass collection device 100.
[0058] In addition, to ensure that the rear cover plate 200 fits tightly with the grass collection device 100, an elastic element is provided at the connection between the rear cover plate 200 and the machine body 300. In this embodiment, the elastic element is preferably a torsion spring 320. One end of the torsion spring 320 is connected to the rear cover plate 200, and the other end is connected to the machine body 300. The elastic force of the torsion spring 320 can press the rear cover plate 200 against one side of the grass collection bag 20. In this way, the sealing part 202 on the side of the grass collection bag 20 can smoothly enter the receiving space 240 on the side of the rear cover plate 200 and make tight contact with the inner wall of the receiving space 240. There is no gap between the fitting position between the rear cover plate 200 and the grass collection bag 20, and the sealing part 202 will also undergo a certain deformation.
[0059] Therefore, the grass collection device 100 of this application has the characteristics of quick assembly and disassembly. At the same time, after the grass collection device 30 is connected to the machine body 300, the sealing of the connection position can be guaranteed.
[0060] Specifically, during assembly, the grass collecting device 100 has its connecting part 201 of the grass collecting bag 20 covering the first bracket 101. The first bracket 101 supports the front end of the grass collecting bag 20 and forms an opening 203. The second bracket 102 extends into the grass collecting bag 20 and supports the rear end of the grass collecting bag 20. The grass collecting bag 20 can then be assembled and formed on the outside of the mounting bracket 10. After forming, the grass collecting device 100 is suspended on the machine body 300 by the hook 104, thus completing the quick installation. After installation, the opening 203 of the grass collecting bag 20 and the grass outlet on the machine body 300 are aligned. Corresponding to 310, the rear cover plate 200 on the machine body 300 is attached to one side of the grass collection bag 20 under the force of the torsion spring 320, so that the sealing part 202 on the side of the grass collection bag 20 can smoothly enter the receiving space 240 on the side of the rear cover plate 200 and make tight contact with the inner wall of the receiving space 240, thereby ensuring that the connection position between the grass collection bag 20 and the machine body 300 is sealed. The inner cavity of the grass collection bag 20 forms a closed grass collection space, which can prevent foreign objects and grass clippings thrown out of the grass outlet 310 from being blown towards the operator from the gap at the connection position between the grass collection bag 20 and the machine body 300.
[0061] Furthermore, refer to Figure 3 , Figure 5 After the grass collection bag 20 is fitted onto the outside of the mounting bracket 10, the grass collection bag 20 is supported into a stable shape. The grass collection bag 20 includes a first side 20a1, a second side 20a2, a third side 20a3, a top surface 20b, and a bottom surface 20c.
[0062] The ends of the first side 20a1, the second side 20a2, the third side 20a3, the top surface 20b, and the bottom surface 20c form the opening 203 of the grass collection bag 20.
[0063] The grass outlet 310 on the machine body 300 faces the second side 20a2, and the grass outlet 310 is directed towards the junction of the first side 20a1 and the second side 20a2.
[0064] In this embodiment, the bottom surface 20c of the grass collection bag 20 is a flat plate. The material density of the first side surface 20a1, the second side surface 20a2, and the top surface 20b is greater than that of the third side surface 20a3. This means that the mesh aperture of the first side surface 20a1, the second side surface 20a2, and the top surface 20b is smaller than that of the third side surface 20a3. In other words, the air permeability of the material of the first side surface 20a1, the second side surface 20a2, and the top surface 20b is less than that of the material of the third side surface 20a3.
[0065] When grass clippings are thrown into the grass collecting device 100 along the tangential rotation of the blades, specifically towards the angle between the first side 20a1 and the second side 20a2, the third side 20a3, with its larger mesh size, increases the air permeability of the grass collecting device 100. After the grass clippings are thrown into the grass collecting device 100, the air inside the grass collecting bag 20 is quickly expelled through the third side 20a3, improving grass collecting efficiency. When the grass collecting device 100 has good air permeability, no swirling air will form inside the grass collecting bag 20, preventing the collected grass clippings from being carried back to the grass outlet 310.
[0066] Example 2
[0067] Reference Figure 1 , Figure 12 Based on the same technical concept, this application provides a lawnmower 400, including the grass collection device 100 in the above embodiments. The lawnmower 400 includes a lawnmower body 410, and the grass collection device 100 is installed on one side of the lawnmower body 410. In this embodiment, the lawnmower body 410 is the machine body 300 mentioned in the above embodiments.
[0068] After the grass collection device 100 is installed on the lawnmower body 410, foreign objects and grass clippings will not fly out from the connection point between the grass collection bag 20 and the lawnmower body 410 during the use of the lawnmower 400.
[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them.
